no. 1 approach

[0034] Such as figure 1 As shown, the vehicle 50 of the first embodiment includes an automatic driving control system 100 . The automatic driving control system 100 includes an automatic driving ECU 200 (Electronic Control Unit: Electronic Control Unit), a vehicle control unit 300 , a support information acquisition unit 400 , a driver warning unit 500 , and a power supply unit 600 . In addition, in this specification, the vehicle 50 is also called "own vehicle 50".

[0035] The automatic driving ECU 200 is a circuit including a CPU and a memory. The automatic driving ECU 200 functions to control the automatic driving of the vehicle 50 as the automatic driving control unit 210 by executing the computer program stored in the nonvolatile storage medium, and also functions to recognize the situation related to the vehicle 50 as the situation recognition unit 220 . . The function of the situation recognition unit 220 will be described in detail later.

[0036] The vehicle cont...

no. 2 approach

[0058] Such as Figure 5 As shown, the steps of the power supply connection change processing in the second embodiment are as follows: image 3 Steps S120 and S130 are added between step S40 and step S50, and steps S150 and S160 are added after step S60. In addition, in Figure 5 In the processing procedure of , when step S30 makes a negative judgment, it proceeds to step S120 described later.

[0059] In steps S120 and S130, when the host vehicle 50 temporarily stops or runs slowly near the center of the intersection, if the situation recognition unit 220 recognizes the preset steering angle change situation, the automatic driving control unit 210 will follow the predetermined steering angle change situation. The first steering angle of the traveling route (the first steering angle indicated by the steering angle indication value for automatic driving) is changed to a different second steering angle to alleviate the influence of the host vehicle 50 being rear-ended by anoth...

no. 3 approach

[0075] Such as Figure 9 As shown, in the third embodiment, step S120 ( Figure 5 ) The detailed steps of judging the steering angle change status are the same as those of the second embodiment ( Figure 6 ) are different, but Figure 5 The overall procedure of the shown power supply connection change process is the same as that of the second embodiment. That is, in the third embodiment, with Figure 5 steps to perform the overall power connection change process, to Figure 9 The detailed steps to execute Figure 5 The judgment of step S120.

[0076] Figure 9 and Figure 6 The difference is that step S300 is added between step S220 and step S230. In step S300, it is determined whether or not a preset rear collision condition is satisfied. When the rear collision condition is satisfied, the process proceeds to step S230 , and the status recognition unit 220 recognizes the steering angle change status. On the other hand, if the rear collision condition is not satisfie...

Abstract

This autonomous driving control system (100) comprises: a plurality of power sources (621, 622); a relay device (630) for changing the connection states of the plurality of power sources; a relay control device (610) for controlling the relay device; a situation recognition unit (220) capable of recognizing the situation or the like of a vehicle which is on a scheduled travel route; and an autonomous driving control unit (210) for controlling autonomous driving. The situation recognition unit recognizes during autonomous driving that the probability of a collision with another body is at leasta prescribed threshold value, and recognizes, among the plurality of power sources, a damage-predicted power source that is predicted to be damaged by the collision with said body. In the event thatthe probability of collision is at least the prescribed threshold value, the autonomous driving control unit instructs the relay control device to disconnect the damage-predicted power source from a specific auxiliary machine and connect the power source other than the damage-predicted power source to the specific auxiliary machine.

Description

[0001] References to related applications [0002] This application claims priority based on Japanese Patent Application No. 2017-95448 filed on May 12, 2017, and the entire contents of the invention are incorporated into this application by reference. technical field [0003] The invention relates to an automatic driving control system of a vehicle. Background technique [0004] JP2016-088134A discloses an automatic driving system of a vehicle. In the above-mentioned automatic driving system, on the basis of simulating the movement trajectory of the obstacle and the own vehicle, the damage degree is calculated for each combination of collision with various objects (other vehicles, guardrails, etc.), so that the damage degree The vehicle is automatically controlled in the lowest possible way. For example, it is disclosed that the host vehicle is stopped by contacting a guardrail to protect pedestrians in order to control the host vehicle with a reduced degree of damage. ...
