Abstract
A gearbox and two hydraulic clutches are disposed between left and right follower wheels of a vehicle. The torque transfer capacity of the hydraulic clutches is controlled to effect the distribution of a torque between the follower wheels. In a low lateral acceleration range, the torque transfer capacity is increased in accordance with an increase in lateral acceleration to enhance the turning performance and the high-speed stability performance. In a high lateral acceleration range, the torque transfer capacity is decreased in accordance with an increase in lateral acceleration, such that it does not exceed a largest frictional force of a wheel acting as an inner wheel during turning movement of the vehicle, thereby insuring a cornering force.
