Abstract:
To provide a four-wheel driving system capable of obtaining a rotating speed very accurately and improving motor controllability. Solution: In a four-wheel drive vehicle, front wheels (14L,14R) are driven by an engine (1), and rear wheels (15L,15R) are driven by an electric motor (5). A high-power alternator (2) is driven by the engine (1), and electric power generated from the alternator (2) drives the motor (5). In addition to controlling the power generation of the high-power alternator (2) and the driving of the motor (5), a 4WD CU (100) estimates an induced voltage (E) of the motor (5) from a voltage (MHV) of the motor and from an output current Ia of the high-power alternator, and estimates a rotating speed Nm of the motor from estimation results on the induced voltage E.

Abstract:
The invention relates to a vehicle driving force control system capable of reducing a shock caused at the time of clutch release. At the time of a shift from a 4-wheel-drive state to a 2-wheel-drive state, a motor rotation angle control unit brings a clutch (4) into a released state when a clutch angle of an engagement portion of the clutch (4) is within a predetermined range. Also, at the time of a shift from the 4-wheel-drive state to the 2-wheel-drive state, the motor rotation angle control unit controls an output torque of a motor (5) so that the clutch angle of the engagement portion of the clutch (4) takes a predetermined value within the predetermined range.
