Patent ID: 8538650

Claim:
A driving force distribution control device which is mounted on a four-wheel-drive vehicle including an engine configured to generate driving force for the vehicle, a transmission device configured to shift rotation of an output shaft of the engine, a clutch configured to engage the output shaft of the engine with an input shaft of the transmission device, and a driving force transmission system capable of transmitting output of the transmission device to main drive wheels which are one of front wheels and rear wheels and auxiliary drive wheels which are the other of the front wheels and the rear wheels, the driving force distribution control device comprising: a control device configured to obtain a torque value to be transmitted to the auxiliary drive wheels, and a driving force transmitting device configured to transmit torque depending on the torque value obtained by the control device to the auxiliary drive wheels, wherein the control device reduces the torque value for a predetermined time when the vehicle is in a stopped state and an increasing speed of engaging force of the clutch is greater than or equal to a predetermined increasing speed value, and wherein the control device reduces the torque value for the predetermined time when the vehicle is in a state where a vehicle speed of the vehicle is lower than a predetermined vehicle speed value and the increasing speed of engaging force of the clutch is greater than or equal to the predetermined increasing speed value.
