Abstract
This paper deals with a driving torque transfer system for front-wheel drive vehicles from a viewpoint of vehicle dynamic control, in which two control techniques, yaw moment control and steering wheel torque compensation, are proposed. The first one adopts the two-degreeof- freedom control structure comprising yaw rate following and stabilizing control, each of which enables to specify the turning and stability performance of vehicle lateral dynamics independently. The second one is a compensation technique which reduces the torque steer due to driving torque transfer between front wheels by applying yaw rate feedback to an electric power steering. Experimental data using a test vehicle demonstrate the effectiveness of these techniques.
