VEHICLE CONTROL SYSTEM AND VEHICLE TRAVEL CONTROL DEVICE

In a vehicle control system that controls a vehicle that performs autonomous driving, the vehicle control system includes an autonomous driving control device that generates a target trajectory for autonomous driving of the vehicle, and an vehicle travel control device that executes vehicle travel control that controls steering, acceleration, and deceleration of the vehicle such that the vehicle follows the target trajectory. The vehicle travel control device is configured to determine whether an operation request condition for washer operation for ejecting washer solution toward a windshield of the vehicle is satisfied, transmit an approval request for the washer operation to the autonomous driving control device when the operation request condition is satisfied, and execute the washer operation when approval for the approval request is received from the autonomous driving control device.
