Provided is a vehicle control system capable of, when a swaying phenomenon occurs during towing, preventing the swaying phenomenon from becoming worse due to driving force reduction control based on an increase in steering angle-related value. This vehicle control system comprises a steering wheel, a driving force control mechanism to control a driving force of a vehicle, and a power-train control module to control the driving force control mechanism. The power-train control module is operable, upon an increase in steering angle, to control an engine to reduce an output torque of the engine and, when a reversal of yaw rate of the vehicle is repeated in a situation where the vehicle is performing a towing operation, to restrict the output torque reduction based on the increase in the steering angle.

Vehicle control system

A vehicle system comprises a brake system comprising a brake pedal and a braking mechanism configured to apply a braking force to a vehicle, and a vehicle control unit operable to automatically stop an engine when the vehicle is decelerated to a given vehicle speed or less during traveling. When it is detected that the brake pedal is manipulated and the vehicle is stopped after automatically stopping the engine, the vehicle control unit is operable to control the braking mechanism to increase the braking force from a current value according to a manipulation amount of the brake pedal up to a given value.
