Abstract:
A differential limiting control apparatus for a four-wheel drive vehicle having a center differential for distributing torque from an engine to the wheels of the vehicle, the control apparatus comprising:accelerator release detecting means for detecting whether an accelerator is released,braking force detecting means for detecting an amount of braking force applied to the wheels of the vehicle; anddifferential limiting force adjustment means for adjusting a differential limiting force of the center differential,wherein the differential limiting force adjustment means sets the differential limiting force to an initial differential limiting force reference value when the accelerator is released and the braking force is less than a braking force reference value, andwherein the differential limiting force adjustment means sets the differential limiting force to zero when the accelerator is released and the braking force is greater than the braking force reference value.
