Further, the CPU 41 travels on the left three-lane road of “Okazaki City, Aichi Prefecture ○○” from the navigation map information and the own vehicle position data stored in the map information DB 25, and passes through each vehicle camera 53. From the image recognition of the road marking, it is detected that the vehicle 2 is traveling in the second lane from the left. Further, the CPU 41 detects from the navigation map information stored in the map information DB 25 and the own vehicle position data that there is a place where it is likely to stop on the left side about 100 m ahead. In addition, the CPU 41 recognizes the road marking via each vehicle-side camera 53, so that the vehicle 2 continues to travel safely in the second lane from the left, via the vehicle ECU 71, the brake 73, the engine 74, and the gear shift. The machine 75 and the steering drive unit 76 are driven and controlled.

Subsequently, in S5, when the vehicle 2 is traveling on a road with two or more lanes on one side, the CPU 41 executes a determination process for determining whether or not the vehicle 2 is traveling on the leftmost lane.
Note that when the vehicle 2 is traveling on one lane or one lane road, the CPU 41 proceeds to the process of S6 without executing the process of S5.

And when the vehicle 2 is drive | working the leftmost lane (S5: YES), CPU41 transfers to the process of S6. In S <b> 6, the CPU 41 determines whether or not there are other vehicles or obstacles around the vehicle 2 based on the information on the surrounding situation of the vehicle 2 acquired by each of the outside cameras 53 and each of the millimeter wave radars 62. Execute the process.
If there are other vehicles or obstacles around the vehicle 2 (S6: YES), the CPU 41 flashes and turns on the brake lamps and the lamps of the left direction indicator via the vehicle ECU 71, etc. The driver of the surrounding other vehicle is informed that an emergency abnormal state has occurred in the vehicle 2 and the vehicle stops immediately, and the process proceeds to S8.
On the other hand, when there is no other vehicle or obstacle around the vehicle 2 (S6: NO), the CPU 41 proceeds to the process of S8.

  Subsequently, in S8, the CPU 41 detects the left edge of the road via each of the outside cameras 53, and drives and controls the brake 73, the engine 74, the transmission 75, and the steering drive unit 76 via the vehicle ECU 71. The vehicle 2 is urgently stopped at the left edge of the road. Further, the CPU 41 ends the process in a state in which the brake lamps and the lamps of the left direction indicator are blinked and lit through the vehicle ECU 71 to appeal the emergency stop to the drivers of other surrounding vehicles.

On the other hand, when the vehicle 2 is not traveling in the leftmost lane in S5 (S5: NO), the CPU 41 proceeds to the process of S9. In S <b> 9, based on the information on the surrounding situation of the vehicle 2 acquired by each of the outside cameras 53 and each of the millimeter wave radars 62, the CPU 41 has no other vehicle behind the left side of the vehicle 2 and can be traveled to the left lane. A determination process for determining whether or not is executed.
If it is determined that there is no other vehicle behind the left side of the vehicle 2 and the vehicle 2 can travel in the left lane (S9: YES), the CPU 41 proceeds to the process of S10. In S10, the CPU 41 flashes and turns on the brake lamps and the lamps of the left direction indicator via the vehicle ECU 71, and an emergency abnormal state occurs in the vehicle 2 in the driver of the other surrounding vehicle, and the left lane enters the left lane. After appealing that the vehicle is traveling, the process proceeds to S11.

Make an emergency stop at the left edge of the road. Further, the CPU 41 maintains a state in which an emergency stop is appealed to the drivers of other surrounding vehicles by blinking and lighting brake lamps and lamps of the left direction indicator via the vehicle ECU 71 (S8).

On the other hand, if it is determined in S9 that another vehicle is traveling behind the left side of the vehicle 2 and cannot move to the left lane (S9: NO), the CPU 41 proceeds to the process of S12. In S <b> 12, the CPU 41 proceeds to the process of S <b> 7 after acquiring information related to other vehicles or the like traveling within about 100 m to 150 m behind the vehicle 2 by the respective outside cameras 53 and the respective millimeter wave radars 62.
In S7, the CPU 41 causes the driver 2 of the other vehicle behind to generate an emergency abnormal state in the vehicle 2 by blinking the brake lamps and the lamps of the left and right direction indicators via the vehicle ECU 71. Appeals that the vehicle will stop urgently, and proceeds to S8.

  In S8, the CPU 41 detects a road display via each vehicle-side camera 53, and drives and controls the brake 73, the engine 74, the transmission 75, and the steering drive unit 76 via the vehicle ECU 71 so that the vehicle 2 is in the travel lane. The vehicle is controlled to travel at the center position, and after confirming that there is no other vehicle approaching from the rear of the vehicle 2 by each of the outside cameras 53 and each of the millimeter wave radars 62, the vehicle is urgently stopped at the center position of the travel lane. Further, the CPU 41 ends the process in a state in which the brake lamp and the lamps of the left and right direction indicators are blinked and lit through the vehicle ECU 71 to appeal the emergency stop to the driver of the other vehicle behind.

  For example, as shown in FIG. 7, when it is determined that the other vehicle 106 is traveling behind the left side of the vehicle 2 and cannot move to the leftmost lane (S9: NO), the CPU 41 Information relating to the situation within about 100 m to 150 m behind the vehicle 2, that is, other vehicles traveling behind the vehicle 2 is acquired by the outside camera 53 and each millimeter wave radar 62 (S12). Then, the CPU 41 flashes and turns on the brake lamps and the lamps of the left and right direction indicators via the vehicle ECU 71, and an emergency abnormal state occurs in the vehicle 2 in the driver of the other vehicle behind. Appeal to stop (S7). Subsequently, the CPU 41 detects a road display via each of the outside cameras 53, and drives and controls the brake 73, the engine 74, the transmission 75, and the steering drive unit 76 via the vehicle ECU 71, so that the vehicle 2 is moved 2 from the left side. After confirming that there is no other vehicle approaching from the rear of the vehicle 2 by each vehicle camera 53 or each millimeter wave radar 62 while controlling to travel in the center position of the second lane, Emergency stop at the center position.

In addition, when the vehicle 2 is abnormally accelerating or decelerating, when the vehicle 2 is meandering 81, or when the vehicle 2 is abnormally approaching the preceding vehicle 101, the guardrail, the median strip, or the like, Is closed or the driver is falling down (S1: YES), the CPU 41 sends a message “Is it all right?” Please reply. " When there is no response from the driver via the microphone 18, or when the driver's eyelid is closed via the driver camera 52 or the driver is falling down, the CPU 41 is not aware of the driver. In other words, it is determined that an emergency abnormal state in which it is difficult for the driver to drive is generated (S2: YES). As a result, the CPU 41 can accurately detect that an emergency abnormal state in which it is difficult for the driver to drive, for example, because the driver is not aware of it.

Further, when the CPU 41 determines that an emergency abnormal state that makes it difficult for the driver to drive due to loss of consciousness or the like (S2: YES), the navigation map information stored in the map information DB 25 and the own vehicle are determined. From the position data, when the vehicle 2 is traveling in the leftmost lane (S5: YES), the brake lamp and the lamps of the left direction indicator are blinked on via the vehicle ECU 71, etc. While appealing to the driver of the other surrounding vehicle that an emergency abnormal state has occurred in the vehicle 2 and the vehicle will stop urgently, the vehicle 2 is stopped urgently at the left edge of the road (S6 to S8).
This makes it possible for the CPU 41 to move the vehicle 2 to the left edge of the road and stop it even in an emergency abnormal state where it is difficult to drive due to the driver's loss of consciousness or the like. This can be prevented beforehand. In addition, the CPU 41 makes an emergency stop to other surrounding vehicles in order to appeal to other surrounding vehicles by flashing and turning on the brake lamps and the left direction indicator lamps via the vehicle ECU 71. It is possible to reliably notify that the situation is present and prevent a rear-end collision or a contact accident.

If it is determined that the vehicle 2 is not traveling in the leftmost lane, there is no other vehicle behind the left side of the vehicle 2, and the vehicle 2 can travel to the left lane (S5: NO, S9: YES) ), The CPU 41 blinks and turns on the brake lamps and the lamps of the left direction indicator via the vehicle ECU 71, and an emergency abnormal state occurs in the vehicle 2 in the driver of the other surrounding vehicle, and the CPU 41 moves to the left lane. After appealing that the vehicle travels, the vehicle 73 is moved and traveled to the left lane by driving and controlling the brake 73, the engine 74, the transmission 75, and the steering drive unit 76 via the vehicle ECU 71 (S10 to S11). The vehicle 2 is brought to an emergency stop at the left edge of the road (S6 to S8).
As a result, the CPU 41 can travel from the traveling lane of the vehicle 2 to the leftmost lane where the vehicle can be stopped to make an emergency stop, and can make the emergency stop more safely.

If it is determined that the vehicle 2 is not traveling in the leftmost lane and cannot move to the left lane (S5: NO, S9: NO), the CPU 41 passes a brake lamp via the vehicle ECU 71. The lamps of the right and left direction indicators are flashed and lit to appeal that the vehicle is to be stopped in an emergency, and the vehicle is stopped at the center of the travel lane (S12, S7 to S8).
As a result, when the CPU 41 determines that the vehicle 2 cannot travel from the traveling lane of the vehicle 2 to the left lane, the CPU 41 makes an emergency stop in the lane in which the vehicle 2 is traveling, and the brake lamp and the left and right direction indicators In order to appeal the fact that the emergency stop is performed by blinking the lamps or the like, it is possible to stop quickly and stop safely.

Furthermore, when the CPU 41 determines that an emergency abnormal state that makes it difficult for the driver to drive due to the driver's loss of consciousness or the like (S2: YES), the CPU 41 indicates the vehicle position together with the vehicle ID. An emergency rescue signal including the position information is transmitted to an information center (not shown) via the communication device 17.
Thereby, when the driver 41 loses consciousness or the like and detects an emergency abnormal state that is difficult to drive, the CPU 41 urgently rescues the driver by reporting the emergency abnormal state to the outside. It becomes possible.
