A vehicle control system that controls a vehicle of a steer-by-wire type, the vehicle control system comprising one or more processors configured to execute: driving assist control that assists driving of the vehicle; and conjunction reaction force control that applies a steering reaction force component to a steering wheel in conjunction with turning of the vehicle caused by the driving assist control, wherein the conjunction reaction force control includes: acquiring a driver turn angle (δx) that is a target turn angle corresponding to a steering angle (θs) of the steering wheel; acquiring a first system turn angle (δy1) that is a target turn angle required by the driving assist control; and an adjustment process that acquires a second system turn angle (δy2) by adjusting the first system turn angle (δy1) according to a steering intention of a driver of the vehicle; characterised in that the conjunction reaction force control includes: applying a steering reaction force component to the steering wheel in a direction of reducing a difference between the driver turn angle (δx) and the second system turn angle (δy2), and the adjustment process acquires the second system turn angle (δy2) by adjusting the first system turn angle (δy1) such that the difference between the second system turn angle (δy2) and the driver turn angle (δx) becomes smaller than a difference between the first system turn angle (δy1) and the driver turn angle (δx). driving assist control that assists driving of the vehicle; and conjunction reaction force control that applies a steering reaction force component to a steering wheel in conjunction with turning of the vehicle caused by the driving assist control, wherein the conjunction reaction force control includes: acquiring a driver turn angle (δx) that is a target turn angle corresponding to a steering angle (θs) of the steering wheel; acquiring a first system turn angle (δy1) that is a target turn angle required by the driving assist control; and an adjustment process that acquires a second system turn angle (δy2) by adjusting the first system turn angle (δy1) according to a steering intention of a driver of the vehicle; characterised in that the conjunction reaction force control includes: applying a steering reaction force component to the steering wheel in a direction of reducing a difference between the driver turn angle (δx) and the second system turn angle (δy2), and acquiring a driver turn angle (δx) that is a target turn angle corresponding to a steering angle (θs) of the steering wheel; acquiring a first system turn angle (δy1) that is a target turn angle required by the driving assist control; and an adjustment process that acquires a second system turn angle (δy2) by adjusting the first system turn angle (δy1) according to a steering intention of a driver of the vehicle; characterised in that the conjunction reaction force control includes: applying a steering reaction force component to the steering wheel in a direction of reducing a difference between the driver turn angle (δx) and the second system turn angle (δy2), and the adjustment process acquires the second system turn angle (δy2) by adjusting the first system turn angle (δy1) such that the difference between the second system turn angle (δy2) and the driver turn angle (δx) becomes smaller than a difference between the first system turn angle (δy1) and the driver turn angle (δx).
