摘要： To provide a vehicle driving system capable of engaging a clutch smoothly and early when clutch engaging is requested.A 4WD CU 100 controls a motor 5 and engagement/disengagement of a clutch 4. After the clutch 4 is disengaged, the 4WD CU 100 matches a rotating speed of a section which drives the clutch, and a rotating speed of a section which is driven by the clutch. A speed-synchronizing request detector 140 discriminates whether the driving side requires synchronization in speed. If the speed-synchronizing request detector 140 discriminates that the driving side requires the synchronization in speed, the 4WD CU 100 matches the speed of the driving side with that of the driven side.

摘要： In a vehicle control unit provided with a motor applying a power to a rear wheel, in order to obtain sufficient driving force and braking force in a range in which the rear wheel does not slip sideways at a time when a vehicle turns, a motor torque is continuously controlled by calculating a rear wheel braking and driving force in the range in which the rear wheel does not slip sideways on the basis of a vehicle turning amount and a front wheel torque. Specifically, an absolute value of the motor torque is made smaller in accordance with an increase of the vehicle turning amount, and an absolute value of the motor torque is made larger in accordance with an increase of an absolute value of the front wheel torque.
