ABSTRACT:
A drive force distribution control system for a motor vehicle controls a drive force distribution ratio between drive road wheels based on a steering torque and a lateral acceleration. The drive force distribution control system includes a drive force distribution mechanism for varying the distribution ratio between drive forces to be applied to the drive road wheels, a steering force sensor for detecting the magnitude and direction of the steering force applied to steer the motor vehicle, a lateral acceleration sensor for detecting the lateral acceleration applied to the motor vehicle, a control unit for determining a target distribution ratio between drive forces to be applied to the drive road wheels based on the steering force detected by the steering force sensor and the lateral acceleration detected by the lateral acceleration sensor, and a drive mechanism for actuating the drive force distribution mechanism so that the drive force distribution ratio between the drive forces to be applied to the drive road wheels will be equalized to the target distribution ratio determined by the control unit.
