Active control for distributing driving force over four-wheels of four-wheel drive vehicle.

摘要

An active torque distribution control over four wheels of a motor vehicle detects a longitudinal acceleration and a side acceleration which the vehicle is subject to. Based on these longitudinal and side accelerations, a running mode which the vehicle is involved in is detected, and a torque distribution ratio of a portion of torque delivered to the front wheels to the remaining portion to the rear wheels and a differential limiting force are varied in response to a predetermined control schedule for the running mode detected.
