摘要:
The objective of the present invention is to provide a control device for maintaining vehicle behavior stability by suppressing the transfer of excess driving force to the rear wheels even when the traction control is not effective. According to the present invention, there is provided a control device for a four-wheel drive vehicle, including: a yaw moment control unit for selecting a wheel based on a driving state and generating yaw moment on the vehicle by applying braking force to the selected wheel; a driving force control unit for identifying excess driving force based on the driving state and reducing the identified excess driving force; a limited slip differential control unit for limiting a differential between a front right wheel and a front left wheel; a front and rear driving force distribution control unit for controlling engagement torque of a clutch unit which varies torque distribution between front and rear axles via a center differential; and a switch unit for selecting an operation state or a non-operation state of the driving force control unit, wherein the front and rear driving force distribution control unit sets the engagement torque of the clutch unit at a value when the yaw moment control unit operates while the driving force control unit is in the non-operation state, the value being greater than that of the engagement torque of the clutch unit when the yaw moment control operates while the driving force control unit is in the operation state.
