As shown in
The components may each exchange a signal through an internal communication system (not shown). The signal may contain data. The internal communication system may use at least one communication protocol (e.g., CAN, LIN, FlexRay, MOST, Ethernet).
The driving mode setting apparatus according to at least one embodiment of the present disclosure may include at least one of a device and a logic installed in the vehicle 10. For example, the driving mode setting apparatus may include the controller 140 and the storage 150. In other embodiments, the driving mode setting apparatus may further include any one or more of the sensing unit 110, the navigation information acquisition unit 120, and the interface device 130, or it is functionally integrated and implemented with the autonomous driving system 160.
The sensing unit 110 may be configured to obtain information regarding the occupant inside the vehicle 10. Here, the information regarding the occupant may include: a captured image of the occupant, the occupant's voice, and/or occupant's bio-signals (e.g., heart rate, etc.). The sensing unit 110 is implemented as at least one of a camera or cameras for photographing the interior of the vehicle 10, a microphone for receiving the occupant's voice, and various sensing devices capable of sensing the occupant's bio-signals.
The navigation information acquisition unit 120 may be configured to obtain navigation information of the vehicle 10. The navigation information may include location information of the vehicle 10 and/or map information corresponding to the location information, route information, and information about a road on which the vehicle 10 is traveling. The information on the road may include information on the type of road, its curvature, slope, road width, road construction information, and/or the road surface condition. The type of road may include a highway, an intercity or suburban road, or a city road.
The navigation information acquisition unit 120 may be configured to extract map information corresponding to the current location from among the pre-stored map information based on the current location of the vehicle 10 received from the GPS receiver or extracts the map information corresponding to the current location from an external server using V2X communication. Map information corresponding to the location can be collected. The navigation information acquisition unit 120 may be implemented as a GPS receiver, a communication module, and/or a navigation device.
The interface device 130 may be a device for communication between the vehicle 10 and the occupant. The interface device 130 may be configured to receive an input for setting or changing setting values of various functions and may be configured to provide the occupant with information generated in the vehicle 10. To this end, the interface device 130 may include an input device and/or an output device.
The input device may be implemented as, but is not limited to, at least one physical button, a touch panel and/or a microphone, and it may also be implemented in other ways as long as they receive predetermined information from the occupant. According to some exemplary embodiments, the input device may be combined with the output device to be implemented as a touch display or the like.
The output device may be implemented as, but is not limited to, a display that visually provides information generated in the vehicle 10, a speaker that audibly provides information generated in the vehicle 10, and/or a vibration module that tactually provides information generated in the vehicle 10, and it may also be implemented by other means as long as they can provide information generated in the vehicle 10.
The controller 140 may be configured to interwork with the sensing unit 110, the navigation information acquisition unit 120, the interface device 130, the storage 150, the autonomous driving system 160, and/or the vehicle driving device 170 in order to perform calculations and control related to driving mode setting. The controller 140 may include one or more processors. The controller 140 may be implemented as one or more electronic control units (ECUs), microcontroller units (MCUs), or other sub-controllers mounted on the vehicle 10.
The controller 140 may be configured to set any one of a plurality of predefined driving modes as the driving mode of the vehicle 10. The plurality of predefined driving modes may include, but is not limited to, one or more of a fast driving mode, a normal driving mode, a defensive driving mode, and a custom driving mode. For example, the plurality of predefined driving modes may include a plurality of custom driving modes.
Table 1 shows example driving modes according to at least one embodiment of the present disclosure.
As shown in Table 1, driving modes may each have control element data defined for serving as a reference for a driving plan generation and/or motion control of the vehicle 10. The control element data may include a chassis control mode, a longitudinal acceleration/deceleration control level, a lateral acceleration/deceleration control level, and/or a defensive driving degree.
The chassis control mode may be a sport mode, a normal mode, or a comfort mode. The closer to the sport mode from the comfort mode, the heavier the steering feel may be provided while the suspension becomes lower in height and stiffer in strength.
The longitudinal and lateral acceleration/deceleration control levels may be top, mid, or low. As the acceleration/deceleration control level goes from ‘Low’ to ‘Top’, the vehicle 10 may accelerate or decelerate faster.
The degree of defensive driving may be short-distance preceding driving, medium-distance moderate yield driving, or long-distance yield driving. The closer the degree of defensive driving goes to the long-distance yielding driving from the short-distance preceding driving, the greater distance the vehicle 10 may maintain from other vehicles, have more distance to decelerate, and yield better to surrounding vehicles.
The controller 140 may be configured to receive control element data for the custom driving mode from the occupant by using the interface device 130. For example, the occupant may set the chassis control mode of the custom driving mode to any one of sport mode, normal mode, and comfort mode, it may set the longitudinal and lateral acceleration/deceleration control levels to any one of top, mid, and low, and it may set the degree of defensive driving to any one of short-distance preceding driving, medium-distance moderate yield driving, and long-distance yield driving.
The controller 140 may be configured to set the driving mode of the vehicle 10 based on data obtained from the sensing unit 110, the navigation information acquisition unit 120, and/or the interface device 130.
The controller 140 may be configured to determine the task being performed by the occupant based on the information on the occupant obtained from the sensing unit 110. For example, the controller 140 may determine whether the occupant is sleeping, on a call, reading, and/or video watching, based on a captured image of the occupant. As another example, the controller 140 may determine whether the occupant is in conversation based on the occupant's voice or the like.
According to some exemplary embodiments, the controller 140 may be configured to determine the task being performed by the occupant by using other information than information on the occupant obtained from the sensing unit 110. For example, the controller 140 may be configured to determine whether the occupant is listening to music based on audio information outputted by an audio-video navigation (AVN) device mounted on the vehicle 10.
The controller 140 may be configured to determine a task type corresponding to the task being performed by the occupant from among multiple task types.
According to some exemplary embodiments, the controller 140 may be configured to utilize a task classification table which is a table defining the relationship between tasks and task types as a basis for determining the task type corresponding to the task being performed by the occupant. Table 2 shows an example task classification table.
As shown in Table 2, the controller 140 may be configured to determine a task type corresponding to the task based on the degree of concentration required to perform the task. Here, the task type may be the difficulty of the task. For example, the task difficulty may be divided into top difficulty, mid difficulty, and low difficulty. The top difficulty may correspond to tasks requiring a high degree of concentration to perform, the mid difficulty to tasks requiring ordinary concentration, and the low difficulty to tasks requiring a relatively low degree of concentration.
For example, in response to determining that the task being performed by the occupant is any one of laptop use, tablet use, reading, and the like, the controller 140 may determine the task type to be of the top difficulty. In response to determining that the task being performed by the occupant is any one of sleep, video watching, mobile search, and the like, the controller 140 may determine the task type to be of the mid difficulty. In response to determining that the task being performed by the occupant is any one of a call, staring outside, talking, listening to music, and the like, the controller 140 may determine the task type to be of low difficulty.
Meanwhile, a task classification table such as Table 2 may be preset by a manufacturer or an occupant. For example, the occupant may use the interface device 130 to set tasks to be classified into their respective difficulties.
According to other exemplary embodiments, the controller 140 may be configured to determine the concentration level of the occupant based on the information on the occupant obtained from the sensing unit 110 and accordingly determine a task type corresponding to the task being performed by the occupant. Here, the task type may be the task concentration of the occupant. For example, the task concentration may be classified into a top concentration, a mid concentration, and a low concentration.
For example, in response to determining that the gaze of the occupant does not deviate from a certain range for a first preset time or longer, the controller 140 may determine the task type to be in the top concentration. Additionally, in response to determining that the gaze of the occupant does not deviate from the certain range for less than the first preset time or longer than a second preset time, the controller 140 may determine the task type to be in the mid concentration. Additionally, in response to determining that the gaze of the occupant does not deviate from the certain range for less than the second preset time, the controller 140 may determine the task type to be in the low concentration.
Meanwhile, the present disclosure neither reiterates nor particularly limits the details of the method of determining the task being performed by the occupant or determining the concentration of the occupant based on the obtained information on the occupant from the sensing unit 110.
The controller 140 may be configured to determine the type of road on which the vehicle 10 is traveling based on the navigation information obtained from the navigation information acquisition unit 120. For example, the controller 140 may determine the type of road on which the vehicle 10 is traveling based on the location information of the vehicle 10 and/or map information corresponding to the location information. Here, the type of road may be any one of a highway section, a suburban section, or a city section.
The controller 140 may be configured to control the interface device 130 to output the state of the occupant and the type of road. Accordingly, the occupant may recognize the occupant's state and road type determined by the controller 140 through the information outputted by the interface device 130.
The controller 140 may be configuring to obtain the driving mode inputted by the interface device 130 from the occupant. For example, the occupant may select any one of the plurality of driving modes through the interface device 130.
The controller 140 may be configured to set the selected driving mode as the driving mode of the vehicle 10.
The controller 140 may be configured to combine the occupant's states, the road types, and the occupant's selected driving modes to generate a table (hereinafter, driving mode map) that defines relationships between the occupant's states, the road types, and the occupant's preferred driving modes.
According to some exemplary embodiments, the controller 140 may be configured to combine the occupant's state, road type, and the occupant's selected driving modes to reflect the occupant's tendency in the pre-generated driving mode map.
Table 3 shows an example driving mode map before the occupant's tendency is reflected.
Before the occupant's disposition is reflected, the preferred driving modes for each occupant's state and road type may all be set to a default driving mode (e.g., a normal driving mode).
Table 4 shows an example driving mode map in which the occupant's tendency is reflected.
There may be an example case where the vehicle 10 is driving on the road type that is ‘highway section’, the task being performed by the occupant corresponds to the task type that is of ‘top difficulty’, and the occupant selects ‘defense driving mode’. In this case, the controller 140 may update a preferred driving mode, corresponding to the ‘top difficulty’ and the ‘highway section’ on the driving mode map, to the ‘defense driving mode’.
Meanwhile, in response to multiple citations made of the same occupant status and the same road type through the driving mode selections, the controller 140 may be configured to consider and reflect related data combined on the driving mode map. For example, the controller 140 may be configured to give weight to the number of times the driving mode is selected or the time spent driving in that driving mode and accordingly update the driving mode map with the preferred driving mode that is the most selected driving mode or the longest used driving mode about a specific occupant's state and a specific road type.
Based on the driving mode map, the controller 140 may be configured to set a preferred driving mode corresponding to the occupant's state and road type as the driving mode of the vehicle 10. For example, as shown in Table 4, the controller 140 may be configured to set the ‘defense driving mode’ as the driving mode of the vehicle 10 in response to determining that the task being performed by the occupant corresponds to the task type that is of ‘top difficulty’ and the vehicle 10 is driving on the road type that is ‘highway section’.
The storage 150 may be configured to store various programs and data for setting a driving mode according to at least one embodiment of the present disclosure. For example, the storage 150 may be configured to store a program for the controller 140 to set the driving mode. As another example, the storage 150 may be configured to store criteria for classifying the types of tasks. As yet another example, the storage 150 may be configured to store a driving mode map defining preferred driving modes corresponding to each occupant's state and road type. As yet another example, the storage 150 may be configured to store control element data for each driving mode. The control element data may include a chassis control mode, a longitudinal acceleration/deceleration control level, a lateral acceleration/deceleration control level, and/or a defensive driving degree.
The autonomous driving system 160 may be configured to control the movement of the vehicle 10 based on the set driving mode.
According to some exemplary embodiments, the autonomous driving system 160 may be configured to generate a route for autonomous driving of the vehicle 10. The autonomous driving system 160 may be configured to generate a driving plan for driving along the generated route based on the driving mode of the vehicle 10. The autonomous driving system 160 may be configured to generate a signal for controlling the movement of the vehicle 10 according to the driving plan. The autonomous driving system 160 may be configured to electrically control the vehicle driving devices 170 in the vehicle 10 through the generated signal. The vehicle driving devices 170 may include a steering device, a braking device, a suspension device, and/or a power train.
According to some exemplary embodiments, the autonomous driving system 160 may include one or more processors and memory.
The interface device 130 may provide a GUI.
The GUI according to at least one exemplary embodiment of the present disclosure may include a first graphic object 200 for displaying the road type on which the vehicle 10 is traveling. The first graphic object 200 may include a text and/or an image indicating the road type on which the vehicle 10 is traveling.
The GUI may further include a second graphic object 210 for displaying the current state of the occupant. The second graphic object 210 may include a text and/or an image indicating a task being performed by the occupant. Here, the task being performed by the occupant may be any one of the tasks performed by the occupant within a preset time. For example, the second graphic object 210 may be a text or an image indicating a task that the occupant has performed the most within the last 5 minutes. The second graphic object 210 may further include a text or an image corresponding to the task being performed by the occupant.
According to some exemplary embodiments, the occupant may input a task by using the second graphic object 210. For example, the occupant may select any one of a plurality of tasks by touching one area of the second graphic object 210. For example, when the controller 140 erroneously determines the task being performed by the occupant or when the occupant wants to set a driving mode for another task to perform in the future, the occupant may change the task by using the second graphic object 210.
In another embodiment, the GUI may include a third graphic object 220 for receiving a driving mode input. The occupant may select any one of the plurality of driving modes by using the third graphic object 220. For example, the occupant may touch one region of the third graphic object 220 for selecting any one of a fast driving mode, a normal driving mode, a defensive driving mode, and a custom driving mode.
In other embodiment, the GUI may include at least one or more graphic objects 230 to 260 for displaying information on the current driving mode of the vehicle 10. Here, the current driving mode may be a driving mode selected by the occupant or a driving mode determined by the controller 140.
At least one or more graphic objects 230 to 260 may correspond to control element data of the driving mode, respectively. For example, the GUI may include a fourth graphic object 230 corresponding to the chassis control mode, a fifth graphic object 240 corresponding to the longitudinal acceleration/deceleration control level, and a sixth graphic object 250 corresponding to the lateral acceleration/deceleration control level, and/or a seventh graphic object 260 corresponding to the degree of defensive driving.
At least one or more graphic objects 230 to 260 may be arrow images each indicating a control level or control degree of each control element data. The length or color of at least one or more graphic objects 230 to 260 may vary according to a control level or control degree of control element data. For example, as the lateral acceleration/deceleration control level of the driving mode goes from ‘Top’ to ‘Low’, the length of the sixth graphic object 250 may become shorter.
Meanwhile, in response to a touch being applied to one area of the third graphic object 220, the controller 140 may determine the selected driving mode as the preferred driving mode corresponding to the occupant's current state and the type of road on which the vehicle 10 is currently driving. There may be an example case where the vehicle 10 is driving on the road type that is ‘highway section’, the task that the occupant has performed the most within the last 5 minutes is ‘sleep’, and the occupant selects a fast driving mode by touching one area of the third graphic object 220. In this case, the controller 140 may determine the fast driving mode as the preferred driving mode corresponding to a ‘task of mid difficulty’ and the ‘highway section’.
The following describes a case where the vehicle 10 is driving on the type of road that is a city section as an example which is for convenience of description but does not limit the present disclosure.
When the occupant boards the vehicle 10 for the first time, the vehicle 10 begins driving in a preset initial driving mode (e.g., a normal driving mode).
When the occupant selects a defensive driving mode through the interface device 130 while performing a mobile search, the driving mode setting apparatus may set the preferred driving mode, which corresponds to the currently used road type and the difficulty of mobile search, to the defensive driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘defense driving mode’ with the preferred driving mode corresponding to the ‘city section’ and the ‘mid difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the defensive driving mode for the vehicle 10 to run in the defensive driving mode.
When the occupant selects a custom driving mode through the interface device 130 while reading, the driving mode setting apparatus may set the preferred driving mode, which corresponds to the currently used road type and to the difficulty of reading, to the custom driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘custom driving mode’ with the preferred driving mode corresponding to the ‘city section’ and the ‘top difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the custom driving mode for the vehicle 10 to run in the custom driving mode.
When the occupant selects a normal driving mode through the interface device 130 while listening to music, the driving mode setting apparatus may set the preferred driving mode, which corresponds to the currently used road type and to the difficulty of listening to music, to the normal driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘normal driving mode’ with the preferred driving mode corresponding to the ‘city section’ and the ‘low difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the normal driving mode for the vehicle 10 to run in that mode.
This series of processes may configure a driving mode map reflecting the tendency of the occupant. For example, the driving mode map as shown in Table 4 may be configured.
Thereafter, when the occupant performs a task corresponding to the ‘top difficulty’ (e.g., using a laptop computer, using a tablet, reading, etc.), the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to the ‘city section’ and the ‘top difficulty’, that is, the ‘custom driving mode’. Accordingly, the vehicle 10 runs in the custom driving mode.
When the occupant performs a task corresponding to ‘mid difficulty’ (e.g., sleeping, video watching, or mobile search, etc.), the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to ‘city section’ and ‘mid difficulty’, that is, the ‘defense driving mode’. Accordingly, the vehicle 10 runs in the defensive driving mode.
According to at least one exemplary embodiment of the present disclosure, the driving mode map is configured based on the type of task, allowing the driving mode of the same level to be provided between the preceding task performed by the occupant and the subsequent task performed even if the tasks are different but equally classified into the same type to satisfy the needs of the occupant.
When the occupant boards the vehicle 10 for the first time, the vehicle 10 begins driving in a preset initial driving mode (e.g., a normal driving mode).
When the vehicle 10 is driving in a city section and the occupant selects a defensive driving mode through the interface device 130 for safer driving while watching a video, the driving mode setting apparatus may set the preferred driving mode, corresponding to the currently used road type and to the difficulty of video watching, to defensive driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘defense driving mode’ with the preferred driving mode corresponding to the ‘city section’ and the ‘mid difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the defensive driving mode for the vehicle 10 to run in that mode.
When the vehicle 10 is driving on a highway section and the occupant selects a fast driving mode through the interface device 130 while making a call, the driving mode setting apparatus may set the preferred driving mode, corresponding to the currently used road type and to the difficulty of calling, to the fast driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘fast driving mode’ with the preferred driving mode corresponding to the ‘highway section’ and to the ‘low difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the fast driving mode for the vehicle 10 to run in that mode.
When the vehicle 10 is driving a highway section and the occupant selects a defensive driving mode through the interface device 130 while using a laptop, the driving mode setting may set the preferred driving mode, corresponding to the currently used road type and to the difficulty of laptop use, to the defensive driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘defense driving mode’ with the preferred driving mode corresponding to the ‘highway section’ and to the ‘top difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the defensive driving mode for the vehicle 10 to run that mode.
When the vehicle 10 is driving the suburban section and the occupant selects a custom driving mode through the interface device 130 while making a call, the driving mode setting apparatus may set the preferred driving mode, corresponding to the currently used road type and to the difficulty of calling, to the custom driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘custom driving mode’ with the preferred driving mode corresponding to the ‘suburban section’ and to the ‘low difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the custom driving mode for the vehicle 10 to run in that mode.
When the vehicle 10 is driving the suburban section and the occupant selects a normal driving mode through the interface device 130 and sleeps, the driving mode setting apparatus may set the preferred driving mode, corresponding to the currently used road type and to the difficulty of sleeping, to the normal driving mode. For example, the driving mode setting apparatus may update the driving mode map to provide the ‘normal driving mode’ with the preferred driving mode corresponding to the ‘suburban section’ and the ‘mid difficulty’. Additionally, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the normal driving mode for the vehicle 10 to run in that mode.
This series of processes may configure a driving mode map reflecting the tendency of the occupant. For example, the driving mode map as shown in Table 4 may be configured.
When the occupant in the vehicle 10 running in the city section performs a task corresponding to the ‘mid difficulty’ (e.g., sleeping, video watching, or mobile search, etc.), the driving mode setting apparatus may set as the driving mode of the vehicle 10 the preferred driving mode corresponding to the ‘city section’ and ‘mid difficulty’, that is, the ‘defense driving mode’. Accordingly, the vehicle 10 runs in the defensive driving mode. Thereafter, when the vehicle 10 moves from the city section to the suburban section, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to the ‘suburban section’ and ‘mid difficulty’, that is, the ‘normal driving mode’. Accordingly, the vehicle 10 drives in the normal driving mode.
When the occupant in the vehicle 10 running in the suburban section performs a task corresponding to ‘low difficulty’ (e.g., calling, staring outside, talking, listening to music, etc.), the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to ‘suburban section’ and ‘low difficulty’, that is, ‘custom driving mode’. Accordingly, the vehicle 10 drives in the custom driving mode. Afterward, when the vehicle 10 moves from the suburban section to the highway section, the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to the ‘highway section’ and ‘low difficulty’, that is, the ‘fast driving mode’. Accordingly, the vehicle 10 drives in the fast driving mode.
When the occupant in the vehicle 10 driving on the highway section performs a task corresponding to ‘top difficulty’ (e.g., laptop use, tablet use, or reading, etc.), the driving mode setting apparatus may set the driving mode of the vehicle 10 to the preferred driving mode corresponding to the ‘highway section’ and the ‘top difficulty’, that is, the ‘defense driving mode’. Accordingly, the vehicle 10 drives in the defensive driving mode.
According to at least one exemplary embodiment of the present disclosure, the driving mode map is configured based on the road type on which the vehicle is driving, allowing the driving mode of the same level to be provided even between different roads classified into the same type but running toward different destinations or along different routes of the vehicle 10 to satisfy the needs of the occupant.
