Abstract
A vehicle control system includes a calculator that calculates an integrated controlled variable including a first controlled variable used for controlling the braking/driving force of each wheel so as to optimize the μ utilization ratio of the wheel and a second controlled variable used for controlling the steering angle of each wheel, based on constraints including a target resultant force to be applied to the vehicle body and a limit friction circle of each wheel, a calculator that calculates a steering controlled variable used for controlling only the steering angle of each wheel so as to achieve the target resultant force, and a controller that controls only the steering angle of each wheel, or the steering angle and braking/driving force of each wheel, based on a controlled variable obtained by linearly interpolating the integrated controlled variable and the steering controlled variable.
