Driving force distribution control device and driving force distribution method for four-wheel drive vehicle
An ECU, which functions as a driving force distribution control apparatus for a four-wheel drive vehicle, includes a CPU. The CPU controls a coupling for changing torque distribution of front and rear wheels. The CPU determines either of first and second torque distribution modes based on detection signals of a throttle opening sensor and steering angle sensor, which are operating parameters. In the second torque distribution mode, torque is distributed to the front and rear wheels more equally than in the first torque distribution mode. The CPU sets a duration for the second torque distribution mode when the second torque distribution mode is selected. Until the duration elapses, regardless of the operating parameters, the CPU continues the control of the coupling in the second torque distribution mode.
