Abstract:
A vehicle can ensure an engine torque the driver desires even though the load torque of a generator with respect to the engine varies, and in particular can restrain occurrence of such a risk that an engine stall occurs when a load to the engine is large upon, for example, engagement of a clutch. A controller predicts a load torque of the generator with respect to the engine in future several hundred milliseconds at maximum from the present time, in view of a magnetic field voltage and a speed of the generator at the present time, and controls the engine in accordance with the predicted load torque in order to prevent the output torque of the engine from being insufficient.

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.

Abstract:
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.
