The operation input device 23 is a user interface for an occupant of the own vehicle to operate the system 10 for dealing with a driver abnormality. The operation input device 23 may be hardware such as a keyboard, a push button, an operation lever, or a touch pad, or may be a software key displayed on the screen. A software key as the operation input device 23 may be displayed on the display device 22, and in that case, the display device 22 and the operation input device 23 are configured as one touch panel.

The driver monitor 24 is a device that collects information for determining the state of the driver of the own vehicle, and includes, for example, a camera that detects the posture of the driver, eye opening and closing, the positions of the driver's limbs, and the presence/absence of steering wheel operation. It is composed of a sensor for detecting In addition, the driver monitor 24 may include a biometric sensor for acquiring biometric information (blood pressure, pulse, heartbeat, body temperature, etc.) of the driver.

The manual driving device 26 is a device for the driver to perform a driving operation of the own vehicle, and is, for example, a steering wheel, an accelerator pedal, a brake pedal, a shift lever, or the like. The travel control device 25 is an ECU (Electronic Control Unit) that performs travel control including drive control, acceleration control, and steering control of the host vehicle.

As will be described later, the driver abnormality response system 10 manages the driving authority of the own vehicle, and can transfer the driving authority of the own vehicle between the mobile terminal 21 and the driver. When the driver has the driving authority, the traveling control device 25 controls the own vehicle according to the operation of the manual driving device 26 by the driver, and when the driving authority is on the mobile terminal 21, according to the operation of the portable terminal 21 by the passenger. Control your vehicle.

As shown in FIG. 1, the driver abnormality response system 10 includes a communication unit 11, a mobile terminal list creation unit 12, an abnormality detection unit 13, a mobile terminal list presentation unit 14, a mobile terminal selection unit 15, and a driving authority management. The unit 16 and the vehicle control unit 17 are provided.

The communication unit 11 is a communication unit for the driver abnormality response system 10 to communicate with the passenger's mobile terminal 21. The mobile terminal list creation unit 12 extracts the mobile terminals 21 corresponding to the driving control of the own vehicle from among the passenger's mobile terminals 21 and creates a list of the mobile terminals 21 corresponding to the driving control of the own vehicle. Hereinafter, this list is referred to as a "mobile terminal list". Whether or not the mobile terminal 21 supports the driving control of the own vehicle can be determined based on, for example, whether or not an application program for driving control of the own vehicle is installed in the mobile terminal 21. it can.

The abnormality detection unit 13 detects an abnormality of the driver of the own vehicle based on the information collected by the driver monitor 24. The driver's abnormality detected by the abnormality detecting unit 13 is mainly intended for a state where the driver suddenly cannot drive normally due to cerebrovascular disease, heart disease, digestive system disease, syncope, or the like. , Fatigue, poor physical condition due to drugs, etc. may be included. As the method for detecting the driver abnormality, the method defined in Non-Patent Document 1 above can be used.

The portable terminal list presenting section 14 displays the portable terminal list created by the portable terminal list creating section 12 on the display device 22 when the abnormality detecting section 13 detects an abnormality of the driver, so that the passengers of the own vehicle can see it. Present the mobile device list to. Since the portable terminal list is presented when the driver is abnormal, the "passenger" here does not have to include the driver.

Using the operation input device 23, the passenger can specify a mobile terminal that permits the driving control of the vehicle from the mobile terminals 21 included in the mobile terminal list displayed on the display device 22. The mobile terminal selection unit 15 selects the mobile terminal 21 designated by the passenger as a mobile terminal that permits the driving control of the own vehicle.

The driving authority management unit 16 manages the transfer of the driving authority of the own vehicle. The driving authority management unit 16 gives the driving authority for the vehicle to the driver at normal times (when the driver is normal). However, when an abnormality of the driver is detected and the mobile terminal selecting unit 15 selects the mobile terminal that permits the driving control of the own vehicle, the driving authority management unit 16 notifies the selected mobile terminal 21 of the own vehicle. Transfer driving authority.

The vehicle control unit 17 controls the traveling of the own vehicle by controlling the traveling control device 25 according to the operation of the mobile terminal 21 to which the driving authority of the own vehicle is given. That is, the vehicle control unit 17 controls the traveling of the own vehicle according to the operation of the mobile terminal 21 having the driving right of the own vehicle.

Next, the operation of the driver abnormality response system 10 will be described with reference to the flowcharts of FIGS.

When the driver abnormality response system 10 is activated, the main flow of FIG. 2 is started. In step S101, the "mobile terminal list creation process", which is a process in which the mobile terminal list creation unit 12 creates a mobile terminal list, is started.

FIG. 3 is a flowchart of the mobile terminal list creation process. In the mobile terminal list creation processing, first, the mobile terminal list creation unit 12 searches for the mobile terminal 21 of the passenger of the own vehicle through the communication unit 11 (step S201). When the passenger's mobile terminal 21 is detected (YES in step S202), the mobile terminal list creation unit 12 extracts the mobile terminal 21 corresponding to the driving control of the own vehicle from the detected mobile terminals 21. (Step S203). When the mobile terminal 21 corresponding to the driving control of the own vehicle is extracted (YES in step S204), the mobile terminal list creation unit 12 creates a mobile terminal list listing the extracted mobile terminals 21 (step S205). ), and returns to step S201.

If the mobile terminal 21 of the passenger is not detected (NO in step S202) or if the mobile terminal 21 corresponding to the driving control of the own vehicle does not exist (NO in step S204), the mobile terminal list is not created and the step is performed. Return to S201.

The mobile terminal list creation process of FIG. 3 is repeatedly executed independently of the main flow of FIG.

When a plurality of mobile terminals 21 are included in the mobile terminal list, the arrangement (order) of the mobile terminals 21 in the mobile terminal list may be arbitrary. For example, the portable terminal 21 of a specific passenger can be registered in advance in the driver abnormality response system 10 as being compatible with the driving control of the own vehicle, and the portable terminal list creation unit 12 selects one of the extracted portable terminals 21. Alternatively, the mobile terminal 21 registered in advance may be arranged in the higher rank of the list. Furthermore, priority may be given to each of the mobile terminals 21 to be registered, and the mobile terminals 21 with higher priority may be arranged at the top of the list.

Returning to FIG. 2, in step S102, the "driver abnormality detection process" in which the abnormality detection unit 13 determines whether or not there is an abnormality in the driver is started.

FIG. 4 is a flowchart of driver abnormality detection processing. In the driver abnormality detection processing, first, the abnormality detection unit 13 acquires the information collected by the driver monitor 24 (step S301). Then, the abnormality detection unit 13 analyzes the information and determines whether there is an abnormality in the driver (step S302).

The driver abnormality detection process of FIG. 4 is also repeatedly executed independently of the main flow of FIG.

Returning to FIG. 2, after the mobile terminal list creation processing and the driver abnormality detection processing are started, the mobile terminal list presentation unit 14 determines whether or not a driver abnormality has occurred based on the result of the driver abnormality detection processing. Confirm (step S103). If no driver abnormality has occurred (NO in step S103), step S103 is repeated.

When an abnormality occurs in the driver (YES in step S103), the mobile terminal list presentation unit 14 confirms whether or not the mobile terminal list is created by the mobile terminal list creation processing (step S104). If the mobile terminal list is not created (NO in step S104), the process returns to step S103.

If the mobile terminal list has been created (YES in step S104), the mobile terminal list presentation unit 14 displays the mobile terminal list on the display device 22 and presents the mobile terminal list to the passenger (step S105).

The communication unit 11 also notifies the mobile terminals 21 included in the mobile terminal list (step S106). Upon receiving the notification, the mobile terminal 21 outputs a ring tone, a voice message, a text message, an image, etc. for notifying the passenger who is the user of the notification. Thereby, the passenger who is the user of the mobile terminal 21 included in the mobile terminal list can immediately recognize that his/her mobile terminal 21 is included in the mobile terminal list. The mobile terminal 21 that has received the notification may display, for example, the driving operation screen shown in FIG. 6 as an image for notifying the notification.

FIG. 5 shows an example of the mobile terminal list displayed on the display device 22. In the mobile terminal list of FIG. 5, icons indicating the mobile terminals 21 (mobile terminals A to D) corresponding to the driving control of the own vehicle are arranged side by side, and the passenger operates the operation input device 23, From the mobile terminals 21 included in the mobile terminal list, a mobile terminal that permits the driving control of the vehicle can be designated. That is, the mobile terminal list in FIG. 5 functions as an operation screen for the passenger to specify the mobile terminal 21.

The mobile terminal selection unit 15 selects the mobile terminal 21 designated by the passenger from the mobile terminal list as the mobile terminal that permits the driving control of the vehicle (step S107). When the mobile terminal that allows the driving control of the own vehicle is selected by the mobile terminal selection unit 15, the automatic driving determination unit 18 transfers the driving authority of the own vehicle to the selected mobile terminal 21 (step S108).

In the mobile terminal 21 to which the driving authority of the own vehicle is given, an application program for driving control of the own vehicle is activated, and the driving operation screen as shown in FIG. 6 is displayed on the screen of the mobile terminal 21. In the driving operation screen of FIG. 6, a left turn button 31 for turning the own vehicle to the left and a right turn button for turning the own vehicle to the right are added to the image of the scenery from the driver's seat taken by the vehicle-mounted camera of the own vehicle. 32, a brake button 33 for decelerating the host vehicle, and an accelerator button 34 for accelerating the host vehicle are displayed in a superimposed manner.

The vehicle control unit 17 controls the own vehicle according to the operation of the mobile terminal 21 having the driving authority (step S109). As a result, the passenger who is the user of the portable terminal 21 having the driving authority operates the left turn button 31, the right turn button 32, the brake button 33, and the accelerator button 34 of the driving operation screen shown in FIG. 6, for example. Then, the own vehicle can be driven. Therefore, even if the driver's abnormality occurs and the driver becomes difficult to drive, the passenger drives the vehicle using the mobile terminal 21 and sets the vehicle in a safe place (such as a parking lot or a wide shoulder). Etc.) can be stopped.

After that, when the driver becomes conscious by regaining consciousness, the driver can use the operation input device 23 to instruct the driver abnormality response system 10 to return the driving authority to the driver. .. When an instruction to return the driving authority to the driver is input to the driver abnormality response system 10 (YES in step S110), the driving authority management unit 16 shifts the driving authority of the own vehicle from the mobile terminal 21 to the driver. (Step S111), the process returns to step S103. When the driving authority of the own vehicle returns to the driver, the traveling control device 25 controls the traveling of the own vehicle according to the operation of the manual driving device 26.

As described above, according to the driver abnormality handling system 10 according to the first embodiment, when the driver's abnormality is detected, the driving authority is transferred to the passenger's mobile terminal 21 capable of controlling the driving of the own vehicle. The passenger can operate the mobile terminal 21 to stop the vehicle. Therefore, even when the host vehicle does not have the automatic driving function or the automatic driving cannot be normally performed, it is possible to take measures against the abnormality of the driver.
