A vehicle control system comprises: an engine (4); an accelerator position sensor (10) configured to detect the position of an accelerator pedal; a steering device; a PCM (14) configured to generate a deceleration in the vehicle to control the attitude of the vehicle, when a steering angle-related value as a parameter related to a steering angle of the steering device increases; and a brake unit (16) configured to generate a deceleration in the vehicle, independently of reduction of an output torque of the engine, wherein the PCM is configured to generates the deceleration by means of the reduction of the output torque of the engine when a depression of the accelerator pedal is detected by the accelerator position sensor, and to generate the deceleration by the brake unit (16) when the depression of the accelerator pedal is not detected by the accelerator position sensor.
