摘要： A driving force distribution controller comprises: a control device determining the value of torque which must be transmitted to a rear wheel; and a driving force transmission device transmitting torque corresponding to the torque value determined by the control device to the rear wheel. The control device reduces a torque value calculated based on an opening degree of an accelerator and a rotational speed difference when the rotational speed of an engine is lower than a first threshold value but higher than a second threshold value.

摘要： Discloses is a method of controlling a four-wheel drive vehicle equipped with a torque distribution device capable of changing a torque distribution amount for secondary driven wheels according to an input current to be applied thereto. This method comprises the steps of: applying, to the torque distribution device, a current value corresponding to a target torque distribution amount; and, performing a current changing control for increasing and reducing the input current to the torque distribution device. The step of performing a current changing control includes causing the input current to the torque distribution device to be temporarily increased to a value greater than the current value corresponding to the target torque distribution amount, and then returned to the current value corresponding to the target torque distribution amount, and repeating the temporary increasing of the input current at least at intervals of a predetermined time.
