Abstract

Provided is a vehicle control system capable of improving the responsiveness of a vehicle to a steering operation even when controlling a rear-wheel-driven vehicle. The present invention provides a method of controlling a vehicle (1) in which rear road wheels (2b) are driven. The method includes: a step of selecting a first pedal mode in which an acceleration is set based on a depression amount ofan accelerator pedal, or a second pedal mode in which the acceleration and a deceleration are set; a step of setting a basic torque based on a driving state of the vehicle; a step of setting an incremental torque to allow the basic torque to be increased in accordance with an increase in steering angle; and a step of generating a torque which is determined by adding the incremental torque to thebasic torque, wherein the incremental torque setting step includes setting the incremental torque to different values between when the first pedal mode is selected and when the second pedal mode is selected.

Description

technical field [0001] The invention relates to a vehicle control system, in particular to a vehicle control system and method for controlling a vehicle whose rear wheels are driven by a prime mover. Background technique [0002] A motion control device for a vehicle is described in Japanese Patent No. 5143103 (Patent Document 1). In the vehicle motion control device described in Patent Document 1, deceleration is automatically added to the vehicle as the vehicle turns, thereby preventing lateral slip of the vehicle in an extreme driving range and improving the steering stability of the vehicle. [0003] In addition, Japanese Patent No. 6202478 (Patent Document 2) describes a vehicle behavior control device. In the vehicle behavior control device described in Patent Document 2, the driving force of the vehicle is reduced based on the steering speed of the vehicle to add a target additional deceleration to the vehicle. In this way, in the vehicle behavior control device des...
