CONTROLLER OF TORQUE TRANSFER BETWEEN RIGHT/LEFT WHEELS FOR VEHICLE

摘要

PURPOSE:To improve vehicular traveling stability without damaging rotational ability and increasing energy loss by forming a controller so as to provide appropriate tack-in restraining control with driver's driving operation and driving will reflected in determination of the tack-in. CONSTITUTION:A torque transfer control device is formed by a torque transfer mechanism for giving/receiving torque between left and right rotary wheels by limiting differential motion between the left and right wheel rotary shafts and a control means for controlling the torque transfer mechanism. A tack-in corresponding controller 84 for setting controlled quantity so as to predict vehicular tack-in and restrains the tack-in is arranged in the control means. Standard lateral acceleration speed is calculated at a calculator 84A according to a handle angle and a car body speed 48F in the tack-in corresponding controller 84. A controlled quantity for increasing the torque on rotary inner ring side is set at a setting unit 84B so as to restrain the tack-in when the standard lateral acceleration speed and engine brake manipulated quantity according to an accelerator opening 48G and an accelerator opening speed are respectively large.
