Problems solved by technology

[0004] However, from the viewpoint of vehicle safety, the target trajectory for automatic driving generated by the automatic driving control device may not always be appropriate
For example, target trajectories may be generated that require sharp lane changes, overtaking of preceding vehicles

Embodiment approach

[0025] 1. Overall configuration of the vehicle control system of the present embodiment

[0026] First, the schematic configuration of the vehicle control system of the present embodiment will be described. figure 1 It is a block diagram showing a configuration example for explaining the outline of the vehicle control system of the present embodiment. figure 1 The illustrated vehicle control system 100 is mounted on a vehicle. Hereinafter, the vehicle on which the vehicle control system 100 is mounted will also be referred to as "vehicle V1". The vehicle V1 is an autonomous vehicle capable of autonomous driving. The autonomous driving here is assumed to be level 3 or higher in the class definition of SAE (Society of Automotive Engineers). It should be noted that the power source of the vehicle V1 is not limited.

[0027] The vehicle control system 100 controls the vehicle V1. Alternatively, at least a part of the vehicle control system 100 may be arranged in an external d...

Abstract

This vehicle control system is provided with: an automatic driving control device that generates a target trajectory for automatic driving; and a vehicle travel control device that performs vehicle travel control such that the vehicle follows the target trajectory. The vehicle travel control device determines, on the basis of the driving environment information acquired from the plurality of sensor devices, whether or not an operation condition for travel assistance control for reducing the risk of travel of the vehicle is satisfied, and executes the travel assistance control when the operation condition is satisfied. Furthermore, the vehicle travel control device generates risk information on the basis of the driving environment information, and transmits the risk information to the automatic driving control device before the operating condition is satisfied. The automatic driving control device then generates or corrects the target trajectory based on the received risk information.

Description

technical field [0001] The present disclosure relates to vehicle control systems. Background technique [0002] Japanese Patent Application Laid-Open No. 2017-114195 discloses a technology related to a vehicle control device that can avoid the occurrence of disturbance in travel control when collision avoidance control is performed. The vehicle control device of this technique executes the first control (collision avoidance control) for avoiding the collision of the vehicle with the obstacle. Furthermore, the vehicle control device executes second control such as cruise control and lane keeping control. The vehicle control device recognizes obstacles around the vehicle, and determines whether or not predetermined collision avoidance conditions are satisfied based on the recognition results. When it is determined that the collision avoidance condition is satisfied during the execution of the second control, the vehicle control device stops the second control and executes th...
