    摘要： An apparatus for controlling the driving force of a vehicle is capable of using brakes to limit a differential operation, securing sufficient torque, and suppressing the heating and wearing of the brakes. In the vehicle, an engine generates torque to drive front wheels and/or rear wheels. A front differential allows differential rotation between the front wheels and transmits torque of the engine to the front wheels. A rear differential allows differential rotation between the rear wheels and transmits torque of the engine to the rear wheels. Disk brakes separately brake the front and rear wheels. An ABS/attitude electric control unit controls the disk brakes to limit differential rotation between the front wheels or between the rear wheels. At least one of the front and rear differentials is provided with a differential limiting mechanism.

    摘要： A torque distribution control apparatus for a four-wheel drive vehicle includes a vehicle-speed detector configured to detect a vehicle speed of the vehicle. A wheel-speed detector is configured to detect wheel speeds of main driving wheels and sub-driving wheels of the vehicle. A sub-driving-wheel distribution-torque calculator is configured to calculate a sub-driving-wheel distribution torque in accordance with a rotation speed difference between the main driving wheels and the sub-driving wheels calculated based on an output from the wheel-speed detector. A torque limiter is configured to limit an upper limit of the sub-driving-wheel distribution torque. A controller is configured to control the sub-driving-wheel distribution torque to be transmitted to the right and left sub-driving wheels by right and left torque distribution clutches in accordance with a driving state of the vehicle.
