[First embodiment]
An outline will be described before describing the configuration of the vehicle of the embodiment. In the first embodiment, the driver registers in advance the behavior that the vehicle should take in an emergency during automatic driving. In an emergency, it can be said that the vehicle is in an abnormal state, and it can be said that the vehicle or the passenger is in danger. Further, the behavior that the vehicle should take is also referred to as the operation or running mode of the vehicle, and is hereinafter referred to as “emergency behavior”. For example, when a situation in which a collision cannot be avoided is detected during automatic driving and it is determined that an emergency has occurred, the system is controlled to cause the vehicle to execute a pre-registered emergency behavior.

  For example, it is assumed that the automatic driving system detects that an obstacle (falling stone, etc.) is present in the traveling direction of the vehicle during the automatic driving and determines that the vehicle cannot be stopped before the obstacle even when the brake is applied. In addition, when the collision is unavoidable due to sudden braking, it is assumed that the driver has pre-selected to decelerate the vehicle against a guardrail or the like. In this case, the automatic driving system decelerates and stops the vehicle by causing the vehicle to collide with a guardrail or the like in accordance with the prior selection by the driver. As a result, it is possible to realize automatic driving that reflects the driver's intention to reduce injury to the passenger even if the vehicle is damaged.

  FIG. 1 is a block diagram illustrating a functional configuration of a vehicle 10 according to the first embodiment. The vehicle 10 includes a sensor unit 12, a drive unit 14, an automatic driving control unit 16, an HMI unit 18, and a log storage unit 20. Each block shown in the block diagram of the present specification can be realized in terms of hardware by an element such as a CPU / memory of a computer or a mechanical device, and in terms of software, it can be realized by a computer program or the like. Then, the functional block realized by those cooperation is drawn. Those skilled in the art will understand that these functional blocks can be realized in various forms by a combination of hardware and software.

  The sensor unit 12 includes various devices that detect an operation state of the vehicle 10 or a situation around the vehicle 10. For example, the sensor unit 12 includes an acceleration sensor, an angular velocity sensor, a camera, a sonar, a radar, and the like. The sensor unit 12 includes an obstacle detection unit that detects an obstacle existing around the vehicle 10 and detects a distance to the obstacle. The sensor unit 12 outputs sensor information indicating an operation state of the vehicle 10 or a situation around the vehicle 10.

  The drive unit 14 includes a plurality of types of ECUs (Electronic Control Units) that control the operation of the vehicle 10 and a plurality of types of actuators. For example, the drive unit 14 may include a brake ECU, a steering ECU, a brake actuator, and a steering actuator.

  The log storage unit 20 is a memory (in other words, a storage) that stores the log data output from the automatic operation control unit 16 and the log data output from the HMI unit 18. The log storage unit 20 may be housed in a sealed container having high impact resistance, heat resistance, and water resistance so that it can withstand an impact, fire, submergence, etc. associated with an accident.

  The automatic driving control unit 16 controls the automatic driving of the vehicle 10, and is implemented as an automatic driving control device in the embodiment. The automatic driving control unit 16 includes a registration presence / absence acquisition unit 22, a sensor information acquisition unit 24, a behavior determination unit 26, a vehicle control unit 28, and a log storage unit 30. A computer program including a plurality of modules corresponding to these functional blocks may be stored in the memory of the automatic operation control device. The CPU of the automatic operation control device may exhibit the function of each functional block by executing this computer program.

  The registration presence / absence acquisition unit 22 receives data indicating whether or not the emergency behavior has been registered from the HMI unit 18. The sensor information acquisition unit 24 acquires the sensor information output from the sensor unit 12 and passes it to the behavior determination unit 26.

  The behavior determining unit 26 starts the automatic driving process when data indicating that the emergency behavior has been registered is received by the registration presence / absence acquiring unit 22. That is, the behavior determination unit 26 starts a process for autonomously determining the behavior of the vehicle 10 on the condition that the emergency behavior has been registered. The behavior determination unit 26 determines the behavior of the vehicle 10 according to the sensor information acquired by the sensor information acquisition unit 24. Specifically, the behavior determination unit 26 determines the operation mode of the drive unit 14 (for example, traveling speed, steering angle, brake strength, etc.). ). The behavior determination unit 26 outputs data indicating the determined behavior of the vehicle 10 to the vehicle control unit 28. The vehicle control unit 28 controls the drive unit 14 according to the behavior data input from the behavior determination unit 26.

  The behavior determination unit 26 includes an emergency detection unit 32 and an emergency behavior acquisition unit 34. The emergency detection unit 32 determines whether the traveling state of the vehicle 10 is an emergency according to the sensor information. The emergency means a situation where the vehicle 10 during automatic driving is in danger, and includes, for example, a situation where a collision with an obstacle cannot be avoided. For example, the emergency detection unit 32 detects the presence of an obstacle (such as a falling rock) around the vehicle 10 based on the sensor information, and based on the relationship between the distance to the obstacle and the speed of the vehicle 10, It may be determined whether an obstacle can be safely avoided by automatic driving. If the emergency detection unit 32 determines that it is impossible to safely avoid an obstacle, the emergency detection unit 32 may determine an emergency.

  The emergency behavior acquisition unit 34 transmits data indicating an emergency (also referred to as “emergency notification data”) to the HMI unit 18 when the emergency detection unit 32 determines that an emergency has occurred. The emergency notification data is data that requests provision of emergency behavior. The emergency notification data includes data indicating emergency details (also referred to as “detailed data”) estimated by the behavior determining unit 26 based on the sensor information. Detailed data include, for example, 1) probability of injury to passengers and persons outside the vehicle, 2) number of injuries, 3) degree of injury (life-related, sequelae, serious injury, minor injury, etc.), 4) occurrence of accidents (collisions, etc.) Probabilities may be included.

  The emergency behavior acquisition unit 34 receives data indicating emergency behavior (also referred to as “emergency behavior data”) transmitted from the HMI unit 18 as a response to the emergency notification data. The emergency behavior acquisition unit 34 passes the emergency behavior indicated by the emergency behavior data to the vehicle control unit 28 as the behavior that the vehicle 10 should currently execute.

  When the emergency detection unit 32 determines that an emergency has occurred, the log storage unit 30 stores in the log storage unit 20 a sensor log that includes sensor information that is the basis of the determination. In addition, the log storage unit 30 stores a control log including control contents (that is, emergency behavior) transmitted from the vehicle control unit 28 to the drive unit 14 when the emergency detection unit 32 determines that an emergency has occurred. Save to

  The HMI unit 18 provides an HMI (Human Machine Interface) to the driver and the occupant, and is implemented as an HMI device in the embodiment. The HMI device may be, for example, a car navigation device or an IVI (In-Vehicle Infotainment) device. The HMI unit 18 includes a display unit 40, an input unit 42, a storage unit 44, a display control unit 46, an authentication unit 48, a reception unit 50, a transmission unit 52, a registration presence / absence determination unit 54, a behavior identification unit 56, and a log storage unit 58. Prepare. A computer program including a plurality of modules corresponding to these functional blocks may be stored in the memory of the HMI device. The CPU of the HMI device may exhibit the function of each functional block by executing this computer program.

  The display unit 40 is a device that displays various types of information. The input unit 42 receives information input by the driver. The display unit 40 and the input unit 42 may be integrated as a touch panel.

  The storage unit 44 stores various data. The storage unit 44 stores information for authenticating the driver (for example, smart key information and biometric information such as a face image / fingerprint). In addition, the storage unit 44 stores data relating to the emergency behavior selected by the driver in association with the identification information of the driver. Data on emergency behavior includes emergency conditions and emergency behavior. The emergency condition may be, for example, “cannot avoid a collision that leads to injury to a passenger”. Further, it may be that “a collision leading to an injury to the occupant cannot be avoided and the possibility of an injury to the occupant is 20% or more”. The emergency behavior may be, for example, “stop by colliding with a guardrail or the like”, “do not collide with a guardrail or the like”, or “end automatic operation and return to manual operation”.

  The emergency condition stored in the storage unit 44 corresponds to the detailed emergency data included in the emergency notification data transmitted from the automatic operation control unit 16 to the HMI unit 18. That is, the emergency condition stored in the storage unit 44 includes the traveling state of the vehicle 10 that can be estimated by the behavior determination unit 26 based on the sensor information output from the sensor unit 12.

  The storage unit 44 stores data on an emergency behavior registration screen for allowing the driver to register an emergency behavior. FIG. 2 shows an example of an emergency behavior registration screen. The emergency behavior registration screen 60 includes a plurality of questions 62 (a total of 10 questions in FIG. 2), a plurality of options 64 per question 62, and a registration button 66. The question 62 includes an emergency condition, in other words, a specific example of the emergency. Options 64 include at least the emergency behavior of the vehicle 10 and may further include emergency conditions. The emergency condition included in the question 62 and the option 64 corresponds to the detailed emergency data transmitted from the automatic operation control unit 16 to the HMI unit 18. A plurality of options 64 for one question 62 indicate a plurality of types of travel modes that the vehicle 10 can take in the same emergency. Further, the plurality of options 64 for one question 62 may include a different degree of risk and a traveling mode corresponding to the degree of risk.

  In response to the question 62, the driver selects a specific option 64 that matches his own way of thinking, values, and ethics. When the registration button 66 is operated on the emergency behavior registration screen 60, the input unit 42 stores the combination of the question 62 and the selected option 64 on the emergency behavior registration screen 60 in association with the driver identification information. Stored in section 44.

  The display control unit 46 controls display contents on the display unit 40. For example, the display control unit 46 causes the display unit 40 to display the emergency behavior registration screen stored in the storage unit 44. The authentication unit 48 of the HMI unit 18 authenticates the driver by a known method based on a smart key or biometric information (S10).

  The receiving unit 50 receives a signal transmitted from the automatic operation control unit 16 according to a predetermined communication protocol (for example, CAN (Controller Area Network) protocol). The receiving part 50 of an Example receives the 1st signal (above emergency notification data) which shows the emergency transmitted from the automatic driving | operation control part 16. FIG.

  The transmission unit 52 transmits a signal to the automatic operation control unit 16 according to a predetermined communication protocol. The transmission unit 52 according to the embodiment transmits the second signal (the above-described emergency behavior data) for instructing the emergency behavior stored in the storage unit 44 to the automatic operation control unit 16. Further, the transmission unit 52 transmits a signal indicating whether or not the emergency behavior has been registered to the automatic operation control unit 16.

  The registration presence / absence determination unit 54 determines whether or not the emergency behavior data associated with the identification information of the driver has been registered in the storage unit 44 when the authentication of the driver by the authentication unit 48 is successful. The registration presence / absence determination unit 54 passes the determination result to the transmission unit 52 and causes the transmission unit 52 to transmit the determination result to the automatic operation control unit 16.

  When the emergency notification data is received by the receiving unit 50, the behavior specifying unit 56 selects the driver who has been successfully authenticated by the authentication unit 48 from the emergency behavior stored in the storage unit 44 (that is, the current driver). The emergency behavior corresponding to) is specified. In addition, when the emergency notification data includes detailed data, the behavior specifying unit 56 specifies an emergency behavior that matches the detailed data. For example, when the option (B) is selected on the emergency behavior registration screen 60 of FIG. 2, if the detailed data indicates that the possibility of injury to the occupant is 20% or more, the emergency is caused by causing the vehicle to collide with a guardrail or the like to stop. Specify time behavior. The behavior specifying unit 56 passes the specified emergency behavior data to the transmission unit 52 and causes the transmission unit 52 to transmit the data to the automatic operation control unit 16.

  When the emergency behavior data is transmitted from the transmission unit 52, in other words, when the emergency behavior is specified by the behavior specifying unit 56, the log storage unit 58 is the emergency behavior of the vehicle 10 in an emergency. As a result, a log indicating that it is registered by the driver is stored in the log storage unit 20. This log may include the content of emergency notification data, the content of emergency behavior, the identification information of the driver who registered the emergency behavior, and the registration date and time.

The operation of the vehicle 10 configured as above will be described.
FIG. 3 is a flowchart showing the operation of the vehicle 10 of the first embodiment. The authentication unit 48 of the HMI unit 18 authenticates the driver based on, for example, a face image captured by a camera and identifies the driver (S10). The registration presence / absence determination unit 54 determines whether or not the emergency behavior has been registered by the driver who has been successfully authenticated. If the emergency behavior is not registered (N in S12), the display control unit 46 displays the emergency behavior registration screen on the display unit 40 (S14). When a predetermined registration operation is input to the emergency behavior registration screen (Y in S16), the input unit 42 associates the data related to the emergency behavior selected on the emergency behavior registration screen with the identification information of the driver. Is stored in the storage unit 44 (S18).

  If the emergency behavior has been registered (Y in S12), S14 to S18 are skipped. The transmitting unit 52 transmits data indicating that the emergency behavior has been registered (also referred to as “emergency behavior registered notification”) to the automatic operation control unit 16 (S20). If a predetermined registration operation for the emergency behavior registration screen is not input (N in S16), S18 and S20 are skipped.

  The registration presence / absence acquisition unit 22 of the automatic operation control unit 16 receives the emergency behavior registration completion notification from the HMI unit 18. The automatic driving control unit 16 starts the automatic driving system on condition that the emergency behavior registered notification is received (S22). For example, the behavior determination unit 26 of the automatic driving control unit 16 starts processing for autonomously determining the behavior of the vehicle 10 on the condition that an emergency behavior registered notification has been received. In this way, if the emergency behavior corresponding to the current driver has been registered, the transmission unit 52 of the HMI unit 18 sends a signal indicating the above (the emergency behavior registered notification) to the automatic driving control unit. By transmitting to 16, the automatic operation by the automatic operation control unit 16 is started.

  FIG. 4 is a flowchart showing the operation following FIG. The display control unit 46 of the HMI unit 18 executes main processing as the HMI unit 18 (S24). For example, if the HMI unit 18 is a car navigation device, a map may be displayed as the main process. The automatic operation control unit 16 executes an automatic operation process of system sovereignty (in other words, system initiative) (S26). When an operation for instructing a normal stop of the automatic driving process is input (Y in S28), the automatic driving control unit 16 ends the automatic driving process (S48). If the operation for instructing the normal stop of the automatic driving process is not input, that is, during the execution of the automatic driving (N in S28), if the emergency detection unit 32 has not detected the emergency (S30). N), returning to S26, the normal automatic driving process is continued.

  When the emergency detection unit 32 detects an emergency (Y in S30), the behavior determination unit 26 stops (in other words, suppresses) the autonomous determination of the vehicle behavior. The emergency behavior acquisition unit 34 transmits emergency notification data to the HMI unit 18 (S32). When the receiving unit 50 of the HMI unit 18 receives the emergency notification data (Y of S34), the behavior specifying unit 56 is the emergency behavior registered in advance by the driver, and the current driving situation (occupant injury probability, etc.) ) Is identified (S36). The transmission part 52 transmits the data which instruct | indicates execution of the emergency behavior identified by the behavior specific | specification part 56 to the automatic driving | operation control part 16 (S38). The log storage unit 58 stores log data including the driver identification information and the emergency behavior specified in S36 in the log storage unit 20 (S40).

  If emergency notification data has not been received (N in S34), S36 to S40 are skipped. When a predetermined end condition is satisfied, such as when the power is turned off or an end operation is input (Y in S42), the flow of FIG. If the end condition is not satisfied (N in S42), the process returns to S24 and the main process of the HMI unit 18 is continued.

  The emergency behavior acquisition unit 34 of the automatic operation control unit 16 receives the emergency behavior data transmitted from the HMI unit 18. The vehicle control unit 28 controls the drive unit 14 to execute the emergency behavior indicated by the received data (S44). The log storage unit 30 stores the sensor log and the control log in the log storage unit 20 (S46). The automatic operation control unit 16 ends the automatic operation process and ends the flow of this drawing (S48).

  According to the HMI unit 18 of the first embodiment, the vehicle can behave in accordance with the driver's intention in an emergency during automatic driving. In addition, the HMI unit 18 and the automatic driving control unit 16 record the log relating to the executed emergency behavior in a safe area, so that the emergency behavior based on the driver's intention is executed in the subsequent verification. It becomes clear and the scope of responsibility can be clarified.

[Second Embodiment]

Send. As a result, the emergency behavior selected by the driver is registered in the cloud server 70.

  The emergency behavior acquisition unit 84 acquires data on the emergency behavior registered in advance by the driver who has been successfully authenticated by the authentication unit 48 from the cloud server 70 and stores the data in the storage unit 44. The data related to the emergency behavior acquired from the cloud server 70 is the same as the data registered in the storage unit 44 from the emergency behavior registration screen 60 in the first embodiment.

  FIG. 6 is a flowchart showing the operations of the vehicle 10 and the cloud server 70 of the second embodiment. This figure corresponds to FIG. 3 of the first embodiment. The authentication unit 48 of the HMI unit 18 authenticates the driver by a known method based on a smart key or biometric information (S50). The emergency behavior acquisition unit 84 transmits an emergency behavior provision request including identification information of a driver who has been successfully authenticated to the cloud server 70 (S52).

  The cloud server 70 searches the emergency behavior data corresponding to the driver using the driver identification information received from the vehicle 10 as a key (S54). The cloud server 70 transmits the search result to the vehicle 10 (S56). Specifically, when emergency behavior data corresponding to the driver of the vehicle 10 has been registered, a search result including the emergency behavior data is transmitted to the vehicle 10. If emergency behavior data corresponding to the driver of the vehicle 10 is not registered, a search result indicating that is transmitted to the vehicle 10. The emergency behavior acquisition unit 84 of the HMI unit 18 acquires the search result transmitted from the cloud server 70.

  When the driver's emergency behavior is not registered in the cloud server 70, that is, when a search result indicating no match is received from the cloud server 70 (N in S58), the display control unit 46 of the HMI unit 18 A behavior registration screen is displayed on the display unit 40 (S60). When a predetermined registration operation is input on the emergency behavior registration screen (Y in S62), the input unit 42 stores data related to the emergency behavior selected by the driver in association with the identification information of the driver. 44 (S64). The emergency behavior registration unit 82 registers the data related to the emergency behavior selected by the driver and the identification information of the driver in the cloud server 70 (S66). The cloud server 70 stores the combination of the emergency behavior received from the HMI unit 18 and the driver in the storage unit 74 (S68).
