Title:
CONTROL DEVICE OF FOUR-WHEEL-DRIVE VEHICLE
Document Type and Number:
Japanese Patent JP2022118390
Kind Code:
A
Abstract:
To provide a four-wheel-drive vehicle based on a front-engine-rear-drive vehicle, which is configured so that behavior of the vehicle is stabilized further.SOLUTION: A control device of a four-wheel-drive vehicle comprises an engine 2, a motor 30, a transfer 54, an adjustment mechanism (an electromagnetic coupling mechanism 58) that changes a distribution ratio between torque of a front wheel 61 and torque of a rear wheel 62, and a control unit 10. The control unit sets the distribution ratio to a first distribution ratio at which the torque of the rear wheel is larger than the torque of the front wheel, in a running state where the engine generates driving torque; sets the distribution ratio to a second distribution ratio at which the distribution ratio of the torque of the front wheel is larger than the first distribution ratio, in a braking state where an engine brake is operated; and sets the distribution ratio to a third distribution ratio at which the distribution ratio of the torque of the front wheel is larger than second distribution ratio, in a braking state where the engine brake is operated and regenerative braking of the motor is performed.SELECTED DRAWING: Figure 5
