The present invention relates to a control apparatus, a system, a computer-readable storage medium, and a control method.
Patent document 1 describes “setting of a route in which a section where automated drive can be performed and a section where the automated drive is not performed are not mixed”.
Hereinafter, the present invention will be described by way of exemplary embodiments of the invention, but the following embodiments are not intended to restrict the invention according to the claims. In addition, not all combinations of features described in the embodiments necessarily have to be essential to solving means of the invention.
The movable object 20, the notification server 40, and the content server 50 are connected to a network 90. The network 90 includes a communication line such as the Internet or a mobile communication network. The notification server 40 communicates with the content server 50 and the movable object 20 through the network 90.
The content server 50 obtains and stores, in a database, video data and text data provided by video distribution services on the network 90, text data and image data such as still image data and video data included in posted information on social network services (SNS), and image data and text data included in web pages and the like. In addition, the content server 50 obtains and stores, in the database, audio data, text data, and image data distributed through television broadcast and radio broadcast. The content server 50 obtains and stores, in the database, advertisement data from an advertisement distribution company. In addition, the content server 50 obtains and stores, in the database, news information from news providing company. The content server 50 sends content data to the notification server 40 according to a request from the notification server 40.
The content data may include, for example, time instant information, location information, and phenomenon information. The time instant information indicates a time instant associated with the phenomenon information. The location information indicates a location associated with the phenomenon information. The phenomenon information includes weather information, accident information, event information, roadwork information, traffic jam information, advertisement information, news information, and the like.
The movable object 20 has an automated driving function. The movable object 20 is provided with an automated drive control apparatus 22, a notification apparatus 24, a communication apparatus 28, and a sensor 29. The sensor 29 is provided with a radar, a camera, a positioning apparatus, a speed sensor, and the like. The automated drive control apparatus 22 is configured to provide the movable object 20 with the automated driving function. For example, the automated drive control apparatus 22 controls steering or acceleration and deceleration of the movable object 20 in an automated manner. The automated drive control apparatus 22 uses information obtained by the sensor 29 to control the steering or the acceleration and deceleration of the movable object 20 in an automated manner. The automated driving function by the automated drive control apparatus 22 may be an automated driving function for controlling the steering and the acceleration and deceleration in a mode in which an intervention degree to the driving by the system is increased. In this case, since an intervention degree to the driving by an occupant of the movable object 20 is relatively decreased, an attention degree of the occupant to a notification tends to be increased, which is preferable to provision of notification data. The automated drive control apparatus 22 may have a function of advanced driver-assistance systems (ADAS). The automated drive control apparatus 22 is implemented, for example, by an electronic control unit (ECU) provided with a microcomputer. The communication apparatus 28 communicates with the notification server 40 through the network 90. The communication apparatus 28 is configured to send destination information of the movable object 20 to the notification server 40. In addition, the communication apparatus 28 sends location information of the movable object 20, speed information of the movable object 20, control information related to the automated driving function of the movable object 20, image information of a surrounding of the movable object 20, and information related to the occupant 80 of the movable object 20 which are obtained by the sensor 29, and the like to the notification server 40. The communication apparatus 28 may be configured by including a telematics control unit (TCU). The occupant 80 may be a driver of the movable object 20.
The notification server 40 is configured to generate notification data based on information collected from a plurality of movable objects including the movable object 20 and information received from the content server 50. For example, based on a destination of the movable object 20, the notification server 40 specifies a route scheduled to be travelled to the destination. The notification server 40 decides automated driving levels of the movable object 20 in a plurality of sections in the route scheduled to be travelled based on road information of the route scheduled to be travelled. Note that automated driving levels of SAE J3016 may be applied as the automated driving levels, for example. In this case, an automated driving level 0 to an automated driving level 2 may correspond to a driver-led manual driving mode, and an automated driving level 3 to an automated driving level 5 may correspond to an automated driving mode led by the automated drive control apparatus 22.
In addition, the notification server 40 sets a passing point on the route scheduled to be travelled by the movable object 20. The notification server 40 obtains, from the content server 50, contents serving as a base of notification data provided to the occupant 80 based on information on a point where the automated driving level is switched and the passing point, occupant information obtained from the movable object 20, and the like, and generates the notification data. For example, the notification server 40 obtains content data which is associated with a switching point of the automated driving level of the movable object 20 and also associated with a time instant at which the movable object 20 passes the switching point, and generates a notification plan for setting timing of the notification data to be sent to the movable object 20. For example, the notification server 40 decides timing for presenting the notification data for switching the automated driving level. In addition, the notification server 40 decides a time instant and a duration for presenting the notification data. According to travelling of the movable object 20, the notification server 40 generates the notification data in accordance with the travel plan, and sends the notification data to the movable object 20.
In the movable object 20, when the communication apparatus 28 receives the notification data from the notification server 40, the notification apparatus 24 presents the notification data received by the communication apparatus 28 to the occupant 80. For example, the notification apparatus 24 has a human machine interface (HMI) function, and the notification apparatus 24 is configured to present the notification data in a form of audio information and image information. According to the system 10, the notification data related to the point where the movable object 20 travels and the switching of the automated driving level of the movable object 20 can be presented to the occupant 80 at an appropriate timing.
The control apparatus 200 controls notification data presented to the occupant 80 of the movable object 20 having the automated driving function. The control apparatus 200 is provided with a travel road specification unit 210, a setting unit 220, a notification plan generation unit 240, a notification control unit 270, a failure detection unit 230, and an outside world information obtaining unit 260.
The travel road specification unit 210 is configured to specify a road scheduled to be travelled by the movable object 20 corresponding to the destination set for the movable object 20. Note that the travel road specification unit 210 may obtain, from the movable object 20, information on the road scheduled to be travelled which is decided by a car navigation system included in the movable object 20.
The outside world information obtaining unit 260 is configured to obtain outside world information of the movable object 20. The outside world information may include traffic information, for example. The outside world information obtaining unit 260 may obtain information obtained by the sensor 29 included in the movable object 20 as the outside world information. The outside world information obtaining unit 260 may obtain information obtained by sensors included in a plurality of other movable objects as the outside world information. The outside world information obtaining unit 260 may obtain the outside world information from an external server.
The failure detection unit 230 is configured to detect a failure of the movable object 20. The failure detection unit 230 detects the failure of the movable object 20 during the automated drive of the movable object 20. In a case where the movable object 20 travels at an automated driving level higher than a predetermined automated driving level, the failure detection unit 230 detects the failure of the movable object 20 based on an output value of an actuator included in the movable object 20.
The travel road specification unit 210 specifies the road scheduled to be travelled by the movable object 20 corresponding to a destination set for the movable object 20. The setting unit 220 is configured to set, according to the road scheduled to be travelled, a point for switching from the automated drive to the driver-led manual drive on the road scheduled to be travelled based on the outside world information, and set a scheduled time instant at which the point is passed. The notification plan generation unit 240 is configured to estimate an information intensity of the notification data, and decide an order for presenting detection information of the failure and the notification data in a predetermined period of the scheduled time instant according to the information intensity.
In addition, the setting unit 220 sets a point associated with the failure on the road scheduled to be travelled by the movable object 20 according to the road scheduled to be travelled based on the outside world information, and sets a scheduled time instant at which the point is reached. The point associated with the failure is, for example, a point where a sales outlet or a handing shop of the movable object (which will be referred to as a dealer in the present embodiment), a repair center of the movable object, a car rental shop, a parts shop of the movable object, or the like exists. The notification plan generation unit 240 is configured to generate a notification plan for setting an order for presenting predetermined notification data to the occupant 80 of the movable object 20 according to the point and the scheduled time instant. The notification plan generation unit 240 is configured to incorporate the detection information of the failure into the notification plan according to the point.
The notification control unit 270 is configured to cause presentation based on the notification data in accordance with the notification plan generated by the notification plan generation unit 240. For example, the notification control unit 270 causes notification to the occupant 80 by sending the notification data to the movable object 20 via the communication apparatus 290. The notification control unit 270 may cause change notice of the automated driving mode to the occupant 80 at the switching recommendation point according to the automated driving mode set for the road scheduled to be travelled.
The notification plan generation unit 240 is configured to arrange the notification data in an ascending order of the information intensity increasing stepwise in a predetermined period before the scheduled time instant, and arrange the detection information of the failure to be adjacent to the notification data having the information intensity higher than a predetermined value. The notification data may include advertisement data, and the information intensity of the detection information of the failure may be higher than the information intensity of the advertisement data. Different information intensities may be set in the notification information of the failure depending on a type of the failure.
The automated driving function has a plurality of automated driving modes according to an operation amount of the automated drive control apparatus 22 included in the movable object 20. The notification plan generation unit 240 sets the notification data corresponding to the automated driving mode set for the road scheduled to be travelled. Automated driving levels of SAE J3016 described in the present embodiment are one example of the automated driving modes.
The movable object 20 can set a home location. The home location is, for example, a base of the movable object 20. The home location is, for example, a resident or the like of the occupant 80. A travel mode of the movable object 20 is provided with an outgoing travel mode where a destination is set in a direction in which the movable object 20 departs from the home location, and an incoming travel mode where a destination is set in a direction in which the movable object 20 approaches the home location. In a case where a predetermined action is not taken a predetermined number of times or more in response to notification on the detection information of the failure in the outgoing travel mode, the notification plan generation unit 240 is configured to suppress the notification on the detection information of the failure in the incoming travel mode.
The failure detection unit 230 may detect a failure expected to occur in the future. When a failure is expected to occur in a predetermined time or later in the future, the notification plan generation unit 240 may generate a notification plan for a period longer than a predetermined length which is a notification plan for notification on the failure in a case where the movable object 20 travels at an automated driving level higher than a predetermined automated driving level. In a case where the movable object 20 travels at the automated driving level higher than the predetermined automated driving level, the failure detection unit 230 may specify timing at which the failure is expected to occur in the future based on an output value of the actuator included in the movable object 20. The notification plan generation unit 240 may generate a notification plan for a period longer than the predetermined length based on the predicted timing in the failure detection unit 230.
The setting unit 220 sets a plurality of points including points X1 to X4 on the road scheduled to be travelled 300. For example, in a case where the setting unit 220 decides that the movable object 20 travels on a road from the point X0 to the point X2 at the automated driving level 3, the movable object 20 travels from the point X2 to the point X3 at the automated driving level 2, and the movable object 20 travels from the point X3 to the point X4 at the automated driving level 3, the setting unit 220 sets X2 and X3 as the switching recommendation points for switching the automated driving level.
In addition, in a case where a distance between the point X0 and the point X2 exceeds a predetermined distance, the setting unit 220 sets the point X1 between the point X0 and the point X2. For example, the setting unit 220 may decide the point X1 according to a travel time of the movable object 20. For example, the setting unit 220 may decide a point where the movable object 20 has travelled for approximately 1 hour from the point X0 as X1. In addition, the setting unit 220 sets, on the road scheduled to be travelled 300, the point X4 near a point where a specific spot 390 such as a tourist attraction or a facility exists.
The notification plan generation unit 240 sets one management unit 310 in each of a plurality of periods separated by time instants corresponding to the points set by the setting unit 220. The notification plan generation unit 240 sets a plurality of pieces of notification data 330 in each of the management units 310. As one example, the notification plan generation unit 240 sets notification data 330c for notifying the occupant 80 of the switching of the automated driving level in a management unit ahead of timing corresponding to the switching recommendation point X2. In addition, the notification plan generation unit 240 sets notification data 330b serving as advertisement data and notification data 330a serving as news data before the notification data 330c. The notification plan generation unit 240 selects the advertisement data and the news data to be set as the notification data 330 in the management unit based on interest information of the occupant 80 and a point where the movable object 20 exists at a notification timing. In this manner, the notification plan generation unit 240 generates the notification plan in advance based on the switching recommendation point of the automated driving level, and the notification control unit 270 causes transmission of the notification data to the movable object 20 in accordance with the notification plan generated by the notification plan generation unit 240.
In 5412, the communication apparatus 290 is configured to send request information for content data associated with the point on the road scheduled to be travelled to the content server 50. In 5414, the communication apparatus 290 receives the content data from the content server 50. In 5416, the notification plan generation unit 240 generates notification data based on the content data, and assigns the notification data into the management unit. In 5418, the communication apparatus 290 sends the notification data to the movable object 20. In 5404, the notification apparatus 24 presents notification to the occupant 80 in accordance with the received notification data. In a case where the notification data is advertisement data, after the notification apparatus 24 presents the notification, in 5406, the communication apparatus 28 sends, to the notification server 40, information indicating that the notification data has been presented. In 5420, the notification server 40 stores notification track record information indicating the completion of the notification in the storage device 280. The notification server 40 charges a business operator who has provided the content data based on the notification track record information.
The notification plan generation unit 240 specifies point information y′ (y′1 to y′p) associated with the switching recommendation point y (block 530). The notification plan generation unit 240 obtains notification data C (C1 to Cp) based on the point information y′ (block 540). The notification data C may be notification data generated from the content data obtained from the content server 50. The notification data C may be notification data generated by the notification server 40. For example, the notification data C may be notification data for notification on the switching of the automated driving level.
The notification plan generation unit 240 generates a set D (D1 to Dn) of the notification data B, the notification data R, and the notification data C (block 550). The notification plan generation unit 240 decides an order of the notification data to be set in the management unit from the set D, and sets the notification data (C′1 to C′q) in the management unit (block 560). In this manner, the notification plan generation unit 240 generates the notification plan.
Note that the notification plan generation unit 240 may select one piece of notification data based on priority information associated with each of the plurality of pieces of notification data. In addition, the notification plan generation unit 240 may select a plurality of pieces of notification data. For example, the notification plan generation unit 240 may select the notification data C1 and the notification data R2 as the notification data to be presents in Δt. In this case, the notification plan generation unit 240 may perform such a setting that the notification data C1 and the notification data R2 are shifted in the period Δt to be presented.
In this manner, the notification plan generation unit 240 may generate the plurality of notification plans including the plurality of pieces of notification data from the current location, the passing location, or the destination of the movable object 20, and select and present the notification data corresponding to the switching recommendation point among the plurality of pieces of notification data included in the plurality of generated notification plans.
The notification plan generation unit 240 temporarily selects notification data D (D(tk−1), D(tk), D(tk+1)) that should be presented at each time instant (tk−1, tk, tk+1) in the period Δt. The notification plan generation unit 240 obtains the notification data D in a time series manner to obtain differential information (block 700), and selects the notification data selected as the notification data D such that the differential information satisfies a predetermined condition. For example, in a case where the automated driving level is associated with the notification data, the notification plan generation unit 240 may set a rate of change of the automated driving level per unit time to be below a predetermined value. The association between the notification data and the automated driving level will be described below. In addition, in a case where information intensity of the notification data is associated with the notification data, the notification plan generation unit 240 may set a rate of change of the information intensity per unit time to be equal to or higher than a predetermined value. The information intensity may be associated with the notification data in advance according to the contents presented as the notification data, for example. The notification plan generation unit 240 may set a provided amount of the notification data per unit time which is generated from the advertisement data to be equal to or higher than a predetermined value.
In a case where a combination of the notification data D in which the differential information satisfies a predetermined condition is found, the notification plan generation unit 240 decides the notification data D as the notification data C′ to be presented. Note that in a case where the combination of the notification data D satisfying the predetermined condition is not decided, the setting unit 220 may change the automated driving level of the movable object 20 and search for the notification data D again. In addition, in a case where the notification data satisfying the predetermined condition is not decided, the travel road specification unit 210 may change the road scheduled to be travelled by the movable object 20 and search for the notification data D again.
Regarding the type of the notification data, a “road A” represents notification data associated with a change of the automated driving level.

In the “failure C”, the information intensity 4 is set for the automated driving levels at and above level 3, and the lower information intensity 2 is set for the automated driving level 2 or below. In this manner, the information intensity of the notification data related to the failure is set according to the type of the failure or the period until the failure occurs.
In the “road A” and the “failure A”, the information intensity is set to be higher than the notification data of any other types.
An “advertisement A” represents advertisement data in which it is presumed that the occupant 80 has an interest. The advertisement in which it is presumed that the occupant 80 has the interest may be specified based on history information of the destinations of the occupant 80, a change of facial expression of the occupant 80 in a case where the notification data of the advertisement data is presented, or the like. In the “advertisement A”, the information intensity 3 is set for the automated driving levels at and above level 3, and the lower information intensity 2 is set for the automated driving level 2 or below.

In the “advertisement C”, the information intensity 1 is set for the automated driving levels at and above level 3, and the information intensity 0 is set for the automated driving level 2 or below. For this reason, in a case where the automated driving level is 2 or below, the notification data corresponding to the “advertisement C” is not presented.
“News A” represents news data in which it is presumed that the occupant 80 has an interest. Whether this data is news data in which it is presumed that the occupant 80 has the interest may be specified based on the change of the facial expression of the occupant 80 when the news data is presented, or the like. In the “news A”, the information intensity 3 is set for the automated driving level 3 or above, and the lower information intensity 2 is set for the automated driving level 2 or below.

A “small talk” is notification data presented accompanying with a chat such as an SNS, a conversation system, and a conversation. In the “news C” and the “small talk”, the information intensity 1 is set for the automated driving level 3 or above, and the lower information intensity 0 is set for the automated driving level 2 or below. For this reason, in a case where the automated driving level is 2 or below, the presentation of the notification data of the “news C” and the notification data of the “small talk” is not permitted.
Note that a “type” is one example of an “information attribute”. In addition, an “information intensity” is one example of the “information attribute”. The “information attribute” may be a combination of the “type” and the “information intensity”.
In a case where the notification data is set in the management unit, the notification plan generation unit 240 refers to intensity information and decides an order for setting the notification data such that a change on a time sequence of the information intensity satisfies a predetermined condition.
For example, the notification plan generation unit 240 generates the notification plan for presenting notification data a, notification data b, notification data c, and notification data d in the stated order before the timing at which the point X12 for switching from the automated driving level 4 to the automated driving level 2 is reached. Here, the notification data a and the notification data b are notification data related to an advertisement. The notification data c is notification data related to a failure. For example, the notification data c is notification data for notification on occurrence of the failure. The notification data d is notification data for notification on the switching from the automated driving level 4 to the automated driving level 2.
In addition, the notification plan generation unit 240 generates a notification plan for presenting notification data e, notification data f, notification data g, and notification data h in the stated order before the timing at which the point X13 for switching from the automated driving level 2 to the automated driving level 4 is reached. Here, the notification data e and the notification data f are notification data related to news. The notification data g is notification data related to a failure. For example, the notification data g is notification data for notification on the presence of a dealer that can repair the failure ahead in the travelling of the movable object 20. The notification data h is notification data for notification on the switching from the automated driving level 2 to the automated driving level 4.
In addition, the notification plan generation unit 240 generates a notification plan for presenting notification data i, notification data j, notification data k, and notification data 1 in the stated order before the timing at which the point X14 where the dealer exists is reached. Here, the notification data i and the notification data j are notification data related to an advertisement. The notification data k and the notification data 1 are notification data related to a failure. For example, the notification data k is notification data for notification on the presence of a dealer that can repair the failure nearby. The notification data 1 is notification data for asking the occupant 80 whether the occupant 80 drops by the dealer.
In addition, the notification plan generation unit 240 generates a notification plan for presenting notification data m, notification data n, notification data o, and notification data p in the stated order before the timing at which the point X15 corresponding to the destination is reached. Here, the notification data m and notification data n are notification data related to an advertisement associated with the destination. The notification data o is notification data related to a failure. For example, the notification data o is notification data for notification on occurrence of the failure. The notification data p is notification data for notification on arrival at the destination.
Note that the notification plan generation unit 240 refers to the information intensity illustrated in
For example, a graph 920 of
In this manner, in a case where a failure is detected, the notification plan generation unit 240 regenerates the notification plan to present the notification data related to the failure. For example, the notification plan generation unit 240 regenerates the notification plan to present the notification data related to the failure at the timing close to the timing at which each of the points X12, X13, X14, and X15 is reached. For this reason, a situation can be established where the occupant 80 does not miss the notification data related to the failure.
Note that the notification plan generation unit 240 may determine whether to present the notification data associated with the failure in the incoming travel according to the information intensity set by the type of the failure illustrated in
As one example, in a case where the movable object 20 is a vehicle, the failure detection unit 230 detects a failure of the sensor included in the movable object 20 based on a steering operation amount of the movable object 20, a vehicle speed of the movable object 20, and a tyre turning amount and a variation of a movable object location in a direction orthogonal to a travelling direction of the movable object 20. For example, in a case where the occupant 80 performs the manual drive, the failure detection unit 230 calculates an ideal value of the variation of the movable object location from the steering operation amount, the vehicle speed, and the tyre turning amount detected by the sensor. In a case where a difference between a measured value of the variation of the movable object location and the ideal value exceeds a predetermined value, the failure detection unit 230 determines that verification drive for detecting a failure of the sensor is performed. For example, the difference between the ideal value and the measured value which is detected during the manual drive may be caused by external disturbance such as wind or an inclination of a road surface.
For example, during the automated drive of the movable object 20, the automated drive control apparatus 22 performs the verification drive for reproducing the steering operation amount, the vehicle speed of the movable object 20, and tyre turning amount carried out during the above-described manual drive, and also measures the variation of the movable object location. In a case where a difference between the measured value of the variation of the movable object location in a case where the verification drive is performed and the ideal value exceeds a predetermined value, the failure detection unit 230 determines that a failure may occur in the sensor in a predetermined period. On the other hand, in a case where the difference between the measured value of the variation of the movable object location when the verification drive is performed and the ideal value is equal to or lower than the predetermined value, the failure detection unit 230 determines that there is no possibility that a failure occurs in the sensor. In this manner, the failure detection unit 230 detects the failure of the sensor configured to detect the operation amount of the actuator included in the movable object 20 based on the output value of the actuator related to the operation of the steering during the automated drive. Since there is no intervention from the occupant 80 during the automated drive, the possibility of the failure of the movable object 20 in the sensor or the like can be accurately determined. Note that the failure of the sensor is one example of the failure of the movable object 20.
