Abstract: A control system for a vehicle is provided, which includes a steering wheel configured to be operated by a driver, a steering angle sensor configured to detect a steering angle corresponding to operation of the steering wheel, and a controller configured to set an additional deceleration to be applied to the vehicle based on the steering angle detected by the steering angle sensor to control a vehicle posture when the steering wheel is turned, and applies the additional deceleration to the vehicle. The controller sets the additional deceleration larger when the vehicle travels off road than when the vehicle does not travel off road.

Abstract: The vehicle driving force control device comprises: a behavior control mechanism for reducing a driving force of an engine according to a steering speed; a driving force distribution mechanism for distributing the driving force of the engine to rear road wheels; and an ECU for controlling the mechanisms. The behavior control mechanism reduces the driving force by a target torque reduction amount set based on the steering speed, to thereby generate a deceleration, and the driving force distribution mechanism distributes the driving force to the front road wheels and the rear road wheels based on a distribution rate set for the rear road wheels depending on a traveling state, and the ECU corrects the distribution rate based on the target torque reduction amount during cornering of the vehicle.
