This application claims priority to Chinese Patent Application No. 201910057883.2, filed with the State Intellectual Property Office of P. R. China on Jan. 22, 2019, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the technical field of information processing, and more particularly, to a method and an apparatus for measuring user acceptance of an autonomous vehicle, an electronic device and a storage medium.
With the continued development in automation, robotics and artificial intelligence, vehicles with autonomous driving capabilities have begun to enter into people's daily life. An autonomous vehicle senses the surrounding environment of the vehicle with an in-vehicle sensor, and controls the steering and speed of the vehicle according to information of, for example, the road, the vehicle position, and the obstacle obtained from sensing, so that the vehicle can move safely and reliably on the road.
The US Department of Transportation has issued the Federal Automated Vehicles Policy. China has also introduced the intelligent connected vehicle as a focus of innovation development in the Five-Year Blueprint for Intelligent Manufacturing (2016-2020) issued by the Ministry of Industry and Information Technology and the Ministry of Finance. Other major countries in the world have also provided a lot of support for this course.
Despite all the technological advances and government support, the general public still hesitate to allow fully autonomous vehicles on the road. Whether the public would truly accept autonomous vehicles is a key factor in the application of autonomous driving technology. The instant disclosure provides technology for accurately measuring the user acceptance of autonomous vehicles, thereby providing guidance and support for the development and operation of autonomous vehicles.
A method for measuring user acceptance of an autonomous vehicle, an apparatus, an electronic device and a storage medium according to the present disclosure are used to solve a problem in the art that the development and operation of the autonomous vehicles could not be guided and supported since the user acceptance of the autonomous vehicles cannot be measured accurately in the prior art.

Consequently, by determining the user acceptance of the vehicle to be tested according to the configuration information of the vehicle to be tested and the preset mapping relationship between each functional dimension and each acceptance dimension, the user acceptance of the autonomous vehicle may be measured accurately for guiding and supporting the development and operation of the autonomous vehicle.
Additional aspects and advantages of embodiments of present disclosure will be given in part in the following descriptions, become apparent in part from the following descriptions, or be learned from the practice of the embodiments of the present disclosure.
These and other aspects and advantages of embodiments of the present disclosure will become apparent and more readily appreciated from the following descriptions made with reference to the accompanying drawings.
Embodiments of the present disclosure will be described below in detail, examples of which are illustrated in accompanying drawings. Throughout the drawings, the same or similar reference signs refer to the same or similar elements or elements that have the same or similar functions. The embodiments described below with reference to the accompanying drawings are merely exemplary and intends to illustrate and explain the present disclosure, and should not be construed as a limit to the present disclosure.
With respect to a problem in the art that as the user acceptance of autonomous vehicles cannot be accurately measured, guidance and support cannot be provided for the development and operation of autonomous vehicles, embodiments of the present disclosure provide a method for measuring user acceptance of an autonomous vehicle.
The method for measuring the user acceptance of the autonomous vehicle according to the embodiments of the present disclosure may determine a feature for each of a plurality of functional dimensions of a vehicle to be tested according to configuration information of the vehicle to be tested; determine a current acceptance value for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested, according to a preset mapping relationship between the functional dimension and the acceptance dimension as well as the feature for the functional dimension of the vehicle to be tested; and determine the user acceptance of the vehicle to be tested according to the current acceptance values for the plurality of the acceptance dimensions. In this way, by determining the user acceptance of the vehicle to be tested according to the configuration information of the vehicle to be tested and the preset mapping relationship between the feature for each of the plurality of preset functional dimensions and each of the plurality of acceptance dimensions, the user acceptance of the autonomous vehicle may be measured accurately for guiding and supporting development and operation of the autonomous vehicles.
The method and apparatus for measuring user acceptance of an autonomous vehicle, the electronic device, the storage medium and the computer program according to the present disclosure will be described in detail with reference to the drawings.
As shown in
In step 101, a feature for each of a plurality of functional dimensions of a vehicle to be tested is determined according to configuration information of the vehicle to be tested.
Functional dimensions refer to specific affecting factors that may influence the user acceptance of the autonomous vehicle, which may be determined by means of early-stage literature analyses, expert interviews, user interviews, open-ended questionnaire investigations and the like. In an embodiment, the functional dimensions may include 37 dimensions as shown in table 1.
In the embodiment of the present disclosure, a feature for a functional dimension of a vehicle to be tested refers to a specific characteristic of the vehicle to be tested in each functional dimension that is determined according to configuration information of the vehicle to be tested. For example, when a physical button for emergency braking is provided in the vehicle to be tested, the feature for the functional dimension corresponding to the functional dimension of “Is it possible to brake the vehicle reliably in an emergency?” is “yes”. Therefore, the feature for each of a plurality of functional dimension of the vehicle to be tested may be determined one by one according to the configuration information of the vehicle to be tested.
In step 102, a current acceptance value for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested is determined according to a preset mapping relationship between the functional dimension and the acceptance dimension as well as the feature for the functional dimension of the vehicle to be tested.
The acceptance dimension refers to psychological affecting factors influencing the user acceptance, and may include eight dimensions, which are controllability, benefit perception, popularization anticipation, usability, level of awareness, social support, policy confidence and tendency of seeking new technology. In the embodiment of the present disclosure, the controllability indicates whether the autonomous vehicle may be well controlled or not; the benefit perception indicates whether the autonomous vehicle may make the driving process comfortable and efficient; the popularization anticipation indicates whether the user is optimistic about the traffic system and the supporting services may be quickly completed after the autonomous vehicle is put into use; the usability indicates whether the autonomous driving system is simple to operate and easy to understand; the level of awareness indicates whether the user knows about the automatic driving technology and related products; the social support indicates whether there are some important people supporting to use the autonomous vehicle; the policy confidence indicates whether the user believes that the government will make relevant policies of automatic driving in the benefit of the public; and the tendency of seeking new technology indicates the degree of seeking and acceptance of an individual to a new technology.
As a possible implementation, people's opinions on each acceptance dimension and people's evaluation of the significance of each functional dimension affecting the user acceptance of the autonomous vehicle may be obtained through a questionnaire survey.
Alternatively, the new technology tendency is used for measuring the seeking and degree of acceptance of an individual to a new technology and may be measured with 4 entries, e.g., “when I heard a new technology, I will find a way to experience it”. The policy confidence is used for measuring degree of confidence of the subject that the government will promote the development of the autonomous vehicle and may be measured with 6 entries, e.g. “I believe that our government will strongly support the development of the autonomous vehicle”. The social support is used for measuring the opinions of some important people around the subject on the autonomous vehicle and may be measured with 4 entries, e.g. “my friends think that I should drive an autonomous vehicle”. The level of awareness is used for measuring how the subject knows about the automatic driving technology and may be measured with 4 entries, such as “I've never heard of any technologies or products like this”. The usability is used for measuring the subject's opinions on whether the interaction interface of the autonomous vehicle is easy to use and may be measured with 4 entries, e.g. “I believe that the automatic driving system in the vehicle will be easy to understand”. The popularization anticipation is used for measuring the subject's opinions on whether the roads and social environments may be quickly completed during practical popularization of the autonomous vehicle, and may be measured with 5 entries, such as “I think that obstacles encountered in the popularization of the autonomous vehicle will be overcome soon”. The benefit perception is used for measuring the subject's comprehensive opinions on benefits brought by the autonomous vehicle, and may be measured with 4 entries, such as “the autonomous vehicle will help alleviate driving fatigue”. The controllability is used for measuring a sense of control of the subject over the autonomous vehicle, and may be measured with four entries, such as “if such a product is released, I am confident of driving the vehicle at ease”. During the questionnaire survey, the subject is requested to answer on a 7-point scale, with 1 indicating extremely dissatisfied and 7 indicating extremely satisfied.
When the significance of each functional dimension affecting the user acceptance of the autonomous vehicle is evaluated by means of the questionnaire survey, the subject is requested to answer on a 4-point scale, with 1 indicating no effect and 4 indicating a great effect. According to the investigation results, the functional dimensions are ranked from high to low depending on the significance of each functional dimension as the subject believed, as shown in tables 2 and 3.
In an embodiment, after a large amount of survey data about the acceptance dimensions and the significance of each functional dimension affecting the user acceptance of the autonomous vehicle are acquired, the acquired data may be analyzed through a structural equation model to determine a mapping relationship between each functional dimension and each acceptance dimension. That is, in the embodiment of the present disclosure, before the step 102, the method may further include: performing statistical analysis on data in a statistical data collection by using a structural equation model, to determine the preset mapping relationship between the functional dimension and the acceptance dimension.
The statistical data collection refers to a set of data formed by data acquired through early-stage literature analyses, expert interviews, user interviews, open-ended questionnaire investigations and the like.
The structural equation model is a kind of multivariate statistical analysis technology and is widely applied in the fields of psychology, sociology, management science and the like. Primarily, it may be used to verify whether a measurement scale matches the data. Compared with conventional analysis of reliability and validity, the structural equation model has the following advantages. First, it considers and processes multiple dependent variables simultaneously. Second it allows measurement errors in independent variables and dependent variables. Third, relationships between respective factor structures and factors may be estimated simultaneously. Fourth, a model with complex dependency relations, such as an index dependent on multiple factors or high-order factor taken into consideration, may be processed. And fifth, the fitting degree of the entire model may be estimated.
In the embodiment of the present disclosure, a correlation between each functional dimension and each acceptance dimension, i.e., the influence of each functional dimension on each acceptance dimension, may be determined by performing statistical analyses on respective data in the acquired statistical data collection through the structural equation model. And then, the functional dimension corresponding to each acceptance dimension, i.e., the functional dimension correlated to each acceptance dimension, is determined according to the correlation between each functional dimension and each acceptance dimension. Consequently, the mapping relationship between each functional dimension and each acceptance dimension is determined according to the functional dimension corresponding to each acceptance dimension.
Table 4 shows a relationship between 7 acceptance dimensions and 37 functional dimensions, in which “+” indicates a general correlation, “++” indicates a close correlation, and a blank indicates no correlation. Further, the tendency of seeking new technology is not listed in the table since it belongs to individual difference variables.
As an embodiment, each functional dimension that is tightly associated with the acceptance dimension may be determined as the functional dimension corresponding to the acceptance dimension. For example, as can be seen from table 4, the functional dimensions that are tightly associated with the acceptance dimension “Level of Awareness”, include “9. Is it easy for the user to understand behaviors of the vehicle?”, “10. Are the feedbacks of the vehicle state and the driving state timely and sufficient?”, “26. Total number of people using the autonomous vehicle at present”, “27. Media coverage and evaluation of the autonomous vehicle”, “28. Comments on the autonomous vehicle from the government or research institutes”, “29. Are there any highly reliable test data reports?”, “30. Policy support or restrictions for the autonomous vehicle” and “31. Recognition and reputation of manufacturers of the autonomous vehicle”. Therefore, it may be determined that the functional dimensions corresponding to the acceptance dimension “Level of Awareness”, are “9. Is it easy for the user to understand behaviors of the vehicle?”, “10. Are the feedbacks of the vehicle state and the driving state timely and sufficient?”, “26. Total number of people using the autonomous vehicle at present”, “27. Media coverage and evaluation of the autonomous vehicle”, “28. Comments on the autonomous vehicle from the government or research institutes”, “29. Are there any highly reliable test data reports?”, “30. Policy support or restrictions for the autonomous vehicle” and “31. Recognition and reputation of manufacturers of the autonomous vehicle”. Analogically, the functional dimensions corresponding to other acceptance dimensions may be determined respectively, so as to form the preset mapping relationship between each functional dimension and each acceptance dimension.
In the embodiment of the present disclosure, after determining a features for each of the plurality of functional dimensions of the vehicle to be tested according to the configuration information of the vehicle to be tested, a current acceptance value for each of a plurality of acceptance dimension corresponding to the vehicle to be tested may be determined according to the preset mapping relationship between the functional dimension and the acceptance dimension and the feature for the functional dimension of the vehicle to be tested.
Optionally, the feature for the functional dimension of the vehicle to be tested corresponding to each acceptance dimension may be determined according to the feature for each of the plurality of functional dimensions of the vehicle to be tested, and the acceptance value for each acceptance dimension may be determined according to the number of the features for the functional dimensions of the vehicle to be tested corresponding to each acceptance dimension. That is, the greater the number of the features for the functional dimensions of the vehicle to be tested corresponding to each acceptance dimension is, the greater the acceptance value of each acceptance dimension is. On the other hand, the less the number of the features for the functional dimensions of the vehicle to be tested corresponding to each acceptance dimension is, the less the acceptance value of each acceptance dimension is.
For example, as shown in
It should be noted that the process for determining the current acceptance value for each of the plurality of acceptance dimensions may include, but is not limited to, any examples enumerated above. In practice, the process for determining the current acceptance value for each of the plurality of acceptance dimensions may be preset as necessary, and is not limited to the embodiments of the present disclosure.
In step 103, the user acceptance of the vehicle to be tested is determined according to the current acceptance values for the plurality of the acceptance dimension.
In the embodiment of the present disclosure, after determining the current acceptance value for each of a plurality of acceptance dimensions, the user acceptance of the vehicle to be tested may be determined according to the current acceptance value for each of a plurality of acceptance dimensions.
Optionally, the sum of the current acceptance values for the plurality of the acceptance dimension may be determined as the user acceptance of the vehicle to be tested; or an average value of the current acceptance values for the plurality of the acceptance dimension may be determined as the user acceptance of the vehicle to be tested.
Further, the influence of each acceptance dimension on the user acceptance of the vehicle to be tested may be different. Therefore, the statistical data may be analyzed to determine a relationship between each acceptance dimension and the user acceptance of the vehicle to be tested. Further, each acceptance dimensions may be classified into a direct affecting factor or an indirect affecting factors, or, a mediator variable or an antecedent variable.
Accordingly, in an embodiment of the present disclosure, step 103 may further include: determining a hierarchical relationship among the plurality of acceptance dimensions and conversion weight values among the plurality of acceptance dimensions, and determining the user acceptance of the vehicle to be tested according to the hierarchical relationship among the plurality of acceptance dimensions, the conversion weight values among the plurality of acceptance dimensions, and the current acceptance values for the plurality of the acceptance dimensions.
As an embodiment, the user acceptance of a vehicle to be tested may include two components, i.e., cognitive safety and emotional safety. The correlation between each acceptance dimension and the cognitive safety as well as the correlation between each acceptance dimension and the emotional safety may be expressed with the Pearson correlation coefficient. Further, the mediator variable and antecedent variable in each acceptance dimension may be determined according to the correlation between each acceptance dimension and the cognitive safety and the correlation between each acceptance dimension and the emotional safety. The Pearson's correlation coefficient, also known as the Person product-moment correlation coefficient, indicates the degree of linear correlation and the direction of linear correlation between two variables. The Pearson's correlation coefficient may be denoted by r, with a magnitude between −1 and +1, wherein 1 indicates perfect and positive correlation, −1 indicates perfect and negative correlation, and 0 indicates no correlation. It may be defined mathematically as follows:
Table 5 shows Pearson correlation coefficients between cognitive safety and emotional safety, and eight acceptance dimensions.
It should be noted that the Pearson correlation coefficient reflects a degree of co-variation between every two variables. On the other hand, a partial correlation coefficient reflects the net effect of any antecedent variable on an outcome variable of interest (cognitive safety or emotional safety) when other variables are controlled. It helps to determine the hierarchical relationship in a multi-variable model. That is, in a case where other variables are controlled, variables having significant partial correlation coefficients are the most direct predictor variables (mediator variables) of dependent variables. Further, after other variables are controlled, variables having otherwise significant simple correlation coefficients and insignificant partial correlation coefficients may be more remote predictor variables. That is, the effects of those variables on the dependent variables are reflected through the mediator variables. Table 6 shows partial correlation coefficients between cognitive safety and emotional safety and eight acceptance dimensions, in which each coefficient is net-correlated after the other seven variables are controlled.
As can be seen from tables 5 and 6, the partial correlation coefficients of the popularization anticipation, benefit perception and controllability with respect to the two components of acceptance are still significant, meaning that they may be important mediator variables. The social support has a direct predictive effect on the emotional safety. The usability has a direct predictive effect on the cognitive safety. The seeking tendency for a new technology, policy trust and level of awareness are no longer significant after other variables are controlled, indicating that their effects are likely to be reflected through the effects of the above mediator variables. Therefore, the hierarchical relationship among the acceptance dimensions may be determined as follows, i.e., the popularization anticipation, the benefit perception and the controllability being mediator variables, the other five acceptance dimensions being the antecedent variables, the social support being allowed to predict the emotional safety directly, and the usability being allowed to predict the cognitive safety directly.
As an embodiment, in order to further clarify the hierarchical relationship among the acceptance dimensions, an analysis may be further performed through a structural equation model, to determine the conversion weight values among the acceptance dimensions, and the reliability of the model.
It should be noted that, a value of CMIN/DF between 1 and 3 indicates a model having a parsimonious fit; a value of CMIN/DF less than 1 indicates a model having sample uniqueness. When GFI>0.90, CFI>0.90, TLI>0.90, the closer the value is to 1, the better the fit of the model. A value of RMSEA less than 0.08 indicates a reasonable fit, and a value of RMSEA less than 0.05 indicates a good fit. Consequently, table 7 shows that the model fits very well. The numbers above respective arrows in
It may be understood that the effects of the mediator variables on the acceptance and/or the two components of the acceptance are direct effects, and the effects of the antecedent variables on the acceptance and/or the two components of the acceptance are indirect effects. By extracting and summarizing the direct and indirect effects in the structural equation model, the direct effects, indirect effects and total effects of respective acceptance dimensions on the acceptance, and/or on the two components of the acceptance may be obtained. Table 8 illustrates the direct effects, indirect effects and total effects of respective acceptance dimensions on the two components of the acceptance (i.e., the cognitive safety, emotional safety).
It should be noted that the direct effect of any one of the acceptance dimensions on the cognitive safety or the emotional safety is the standardized regression coefficient (i.e., the conversion weight value) above the arrow that is directly pointing from the acceptance dimension to the cognitive safety or the emotional safety. Further, the indirect effect of any one of the acceptance dimensions on the cognitive safety or the emotional safety is a sum of the products of the conversion weight values on all the paths that are pointing from the acceptance dimension to the cognitive safety or the emotional safety through other mediator variables. For example, the direct effect of the acceptance dimension “controllability” on the cognitive safety is 0.33, and there is no indirect effect since there is no process through an mediator variable. The direct effect of usability on the cognitive safety is 0.11; the effect of the usability on the cognitive safety through the popularization anticipation is 0.10*0.21=0.021; the effect of the usability on the cognitive safety through the benefit perception is 0.40*0.15=0.06; and the effect of the usability on the cognitive safety through the controllability is 0.37*0.33=0.1221. Accordingly, the total indirect effect of the usability is 0.021+0.06+0.1221=0.2021. The total effect of any one of the acceptance dimensions on the cognitive safety or emotional safety is a sum of its direct and indirect effects on the cognitive safety and the emotional safety.
In the embodiment of the present disclosure, after the hierarchical relationship among the plurality of acceptance dimensions, the conversion weight values among the plurality of acceptance dimensions, and the current acceptance values for the plurality of the acceptance dimensions are determined, the user acceptance of the vehicle to be tested may be determined according to the hierarchical relationship among the plurality of acceptance dimensions, the conversion weight values among the plurality of acceptance dimensions, and the current acceptance values for the plurality of the acceptance dimensions. Optionally, the user acceptance of the vehicle to be tested may be determined by the following expression (1).
A=Σ

Here, A is the user acceptance of the vehicle to be tested; ai is a current acceptance value of an ith acceptance dimension; wi is a conversion weight value of the ith acceptance dimension; n is the number of the acceptance dimensions; and i is a sequence number of the acceptance dimension.
It should be noted that the method of determining the user acceptance of the vehicle to be tested may include, but is not limited to, the examples enumerated above. In practice, the method of determining the user acceptance of the vehicle to be tested may be preset as necessary, and is not limited to the embodiment of the present disclosure.
The method for measuring the user acceptance of the autonomous vehicle, the apparatus, the electronic device, the computer readable storage medium and the computer program according to the embodiments of the present disclosure may determine a feature for each of a plurality of functional dimension of a vehicle to be tested according to configuration information of the vehicle to be tested; determine a current acceptance value for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested, according to a preset mapping relationship between the functional dimension and the acceptance dimension as well as the feature for the functional dimension of the vehicle to be tested; and determine the user acceptance of the vehicle to be tested according to the current acceptance values for the plurality of the acceptance dimensions. Consequently, by determining the user acceptance of the vehicle to be tested according to the configuration information of the vehicle to be tested and the preset mapping relationship between each functional dimension and each acceptance dimension, the user acceptance of the autonomous vehicle may be measured accurately for guiding and supporting the development and operation of the autonomous vehicle.
In an embodiment of the present disclosure, after determining the user acceptance of the vehicle to be tested, the performance of the vehicle to be tested may be improved or the operation of the vehicle to be tested may be guided according to the user acceptance of the vehicle to be tested.
The method for measuring the user acceptance of the autonomous vehicle according to the embodiment of the present disclosure will be further described with reference to
As shown in
In step 201, a feature for each of a plurality of functional dimensions of a vehicle to be tested is determined according to configuration information of the vehicle to be tested.
Specific implementations and principle of step 201 may be similar to those in the foregoing embodiments, and details are thus omitted here.
In step 202, a current acceptance value for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested is determined according to a preset mapping relationship between the functional dimension and the acceptance dimension as well as the feature for the functional dimension of the vehicle to be tested.
In the embodiment of the present disclosure, after determining the feature for each of a plurality of functional dimensions of a vehicle to be tested according to configuration information of the vehicle to be tested, the current acceptance value for each of a plurality of acceptance dimensions may be determined according to the preset mapping relationship between the functional dimension and the acceptance dimension as well as the feature for the functional dimension of the vehicle to be tested. Specific implementations and principle for determining the current acceptance value for each of a plurality of acceptance dimensions may be similar to those in the foregoing embodiments, and details are thus omitted here.
Further, during the designing process and manufacturing process the vehicle to be tested, a target operation environment of the vehicle to be tested may be limited, and various functions of the vehicle to be tested may be designed according to the target operation environment of the vehicle to be tested. However, the target operation environment of the vehicle to be tested may be different from the actual operation environment in the survey, leading to inaccurate determination of the current acceptance values for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested. Accordingly, in an embodiment of the present disclosure, after step 202, the method may further include: obtaining a target operation environment corresponding to the vehicle to be tested; and correcting the current acceptance value for each of the plurality of acceptance dimensions corresponding to the vehicle to be tested according to a difference between the target operation environment and a current actual operation environment.
It should be noted that the vehicle to be tested may be a vehicle with some special functions. For example, the vehicle to be tested may be an autonomous vehicle for delivering packages on campus, or an autonomous vehicle for rallying. Therefore, vehicles to be verified for different uses may correspond to different target operation environments, resulting in differences between the target operation environments corresponding to the vehicles to be verified for different uses and the actual operation environments in which the statistical data is collected. For this reason, there may be deviations between the current acceptance value for each of a plurality of acceptance dimensions determined according to the preset mapping relationship between the functional dimension and the acceptance dimension and the acceptance value for each of a plurality of acceptance dimensions of the vehicle to be tested in its target operation environment. That is, in the embodiment of the present disclosure, the current acceptance value for each of a plurality of acceptance dimensions corresponding to the vehicle to be tested may be corrected to improve the reliability of the resultant acceptance value of each acceptance dimension.
As an embodiment, the target operation environment of the vehicle to be tested may be obtained from the configuration information of the vehicle to be tested, or from guidance information such as a user manual of the vehicle to be tested. Then, the difference between the target operation environment and the actual operation environment under test is determined. Then, the current acceptance value for each of the plurality of acceptance dimensions corresponding to the vehicle to be tested is corrected according to the difference between the target operation environment and the current actual operation environment.
Optionally, the functional dimension corresponding to difference information may be first determined according to the difference between the target operation environment and the current actual operation environment. Then, the acceptance dimension having a mapping relationship with the functional dimension corresponding to the difference information is determined according to the mapping relationship between the functional dimension and the acceptance dimension. When the target operation environment of the vehicle to be tested requires the vehicle to be tested to have the features for the functional dimensions corresponding to the difference information, and the current actual operation environment does not require the vehicle to be tested to have the features for the functional dimensions corresponding to the difference information, that is, the target operation environment is stricter than the current actual operation environment, the current acceptance value of the acceptance dimension having the mapping relationship with the functional dimension corresponding to the difference information may be corrected to a smaller value. When the target operation environment of the vehicle to be tested does not require the vehicle to be tested to have the features for the functional dimensions corresponding to the difference information, and the current actual operation environment requires the vehicle to be tested to have the features for the functional dimensions corresponding to the difference information, that is, the target operation environment is simpler than the current actual operation environment, the current acceptance value of the acceptance dimension having the mapping relationship with the functional dimension corresponding to the difference information may be corrected to a larger value.
It should be noted that the method of correcting the current acceptance value of each acceptance dimension corresponding to the vehicle to be tested may include, but is not limited to, examples enumerated above. In practice, the correction method may be preset as necessary, and is not limited to the embodiments of the present disclosure.
In step 203, the hierarchical relationship among the plurality of acceptance dimensions and conversion weight values among the plurality of acceptance dimensions are determined.
In step 204, the user acceptance of the vehicle to be tested is determined according to the hierarchical relationship among the plurality of acceptance dimensions, the conversion weight values among the plurality of acceptance dimensions, and the current acceptance values for the plurality of the acceptance dimensions.
Specific implementations and principle of steps 203-204 may be similar to those in the foregoing embodiments, and details are thus omitted here.
In step 205, an updated mode of the vehicle to be tested is determined according to the hierarchical relationship among the plurality of acceptance dimensions, the conversion weight values among the plurality of acceptance dimensions, and the current acceptance values for the plurality of the acceptance dimensions.
In the embodiment of the present disclosure, the importance of each acceptance dimension may be determined according to the hierarchical relationship among the plurality of acceptance dimensions and the conversion weight values among the plurality of acceptance dimensions. Then, each acceptance dimension with a relatively high level of importance and preferably depending on the capability of the vehicle to be tested may be determined according to the importance of each acceptance dimension. Then, the updated mode of the vehicle to be tested is determined according to the current acceptance values of the acceptance dimensions with a relatively high level of importance and preferably depending on the capability of the vehicle to be tested. In this way, the capability of the vehicle to be tested may be improved according to the determined updated mode.
For example, when the acceptance dimensions include controllability, benefit perception, popularization anticipation, usability, level of awareness, social support, policy trust and tendency of seeking new technology, according to the foregoing discussion on the hierarchical relationship among the acceptance dimensions and the conversion weight value between the acceptance dimensions, the acceptance dimensions with a relatively high level of importance may be determined as controllability, benefit perception, popularization anticipation, usability and social support, in which the controllability, benefit perception and usability depend on the capability of the vehicle.
As an embodiment, after each acceptance dimension with a relatively high level of importance and preferably depending on the capability of the vehicle to be tested, the feature for each of a plurality of the functional dimensions of the vehicle to be tested corresponding to the acceptance dimensions with low current acceptance values may be improved according to the current acceptance value for each of the plurality of acceptance dimensions with relatively high levels of importance and preferably depending on the capability of the vehicle to be tested, thereby increasing the acceptance values of corresponding acceptance dimensions. That is, the functions of the vehicle to be tested per se may be improved so that the functional features of the vehicle to be tested more fit the functional dimensions corresponding to respective acceptance dimensions.
For example, when the acceptance dimensions with high levels of importance and preferably depending on the capability of the vehicle to be tested are determined as controllability, benefit perception and usability, the updated mode shown in table 9 may be determined. The updated mode includes three primary-level sub-targets, i.e., improving controllability, improving popularization anticipation, and improving benefit perception, and a plurality of secondary-level sub-targets corresponding to the three primary-level sub-targets respectively.
In step 206, an operation mode of the vehicle to be tested is determined according to the user acceptance of the vehicle to be tested.
The operation modes of the vehicle to be tested may include sales, lease, full-automatic operation, semi-automatic driving operation and so on.
In the embodiment of the present disclosure, the operation mode of the vehicle to be tested may be determined according to the user acceptance of the vehicle to be tested. That is, the operation mode of the vehicle to be tested may be guided according to the user acceptance of the vehicle to be tested.
Optionally, when the user acceptance of the vehicle to be tested is low, that is, when the user thinks that the vehicle to be tested has a low level of safety, the operation mode of the vehicle to be tested may be determined as a semi-automatic driving operation, in which the vehicle to be tested is equipped with a safety supervisor for intervening in the operation of the vehicle as necessary.
