摘要： A vehicle driving force control apparatus controls a control torque command of an electric motor based on a power supplying condition of an electric power source. The power source supplies electric power to the electric motor that drives at least one wheel of the vehicle. An electric power supplying status detecting section determines an electric power supplying capacity of the electric power source based on the power supplying condition of the power source, while an electric motor torque control section controls the control torque command of the electric motor based on the power supplying condition determined by the electric power supplying status detecting section. Preferably, an internal combustion engine that drives at least one other wheel also drives a generator that acts as the power source of the electric motor. The vehicle driving force control apparatus is especially useful in a four-wheel drive vehicle.

摘要： A vehicle powertrain includes an electric motor (4) and a clutch (12) between the electric motor and a motor driven road wheel (3L, 3R). Powertrain play between the electric motor (4) and the road wheel is eliminated upon determination that powertrain play elimination (PPE) is needed for motor torque transmission to the motor driven road wheel. The PPE includes controlling engagement of the clutch and regulating the electric motor to produce a very small amount of motor torque required for PPE.

摘要： A driving force control apparatus is provided to prevent shocks from being generated during clutch engagement or release. The clutch is maintained in an engaged state and shocks are prevented from accompanying clutch release during creep travel when the target motor torque is equal to or less than a motor torque prescribed value but the average rear wheel speed, which is equivalent to the travel speed of the auto vehicle, is equal to or less than a low-speed prescribed value. In addition, the drive torque on the rear wheels from the electric motor is also brought to the same level as the creep torque on the front wheels from the internal combustion engine, backlash and other types of gaps between the rear axles of the electric motor are closed, and shocks are minimized or prevented during the subsequent transition to a four-wheel drive state.

摘要： A system is provided, which controls a starting and the subsequent vehicle acceleration procedure of a motor vehicle. The system compares a predetermined variable that grows continuously during the starting procedure to a threshold value. It determines a first desired value of torque in response to operator demand, and a second desired value torque in response to acceleration slip. The system performs a feed-forward 4WD control in response to the first desired value of torque when the predetermined variable is lower than or equal to the threshold value. The system determines whether or not driving situation justifies a change from performing the feed-forward 4WD control to performing a feed-back 2/4WD control in response to the second desired value of torque.

摘要： An electric motor diagnosing apparatus is provided in a vehicle having a generator driven by a drive torque of a drive source, an electric motor driven by electric power supplied from the generator, and a wheel driven by the electric motor. The electric motor diagnosing apparatus comprises a counterelectromotive force determining section and an electric motor diagnosing section. The counterelectromotive force determining section determines whether a voltage of electric power supplied from the generator to the electric motor is greater than an induced voltage of a counterelectromotive force of the electric motor. The electric motor diagnosing section drives the electric motor by controlling the generator to supply the electric power to the electric motor, and determines whether the electric motor is rotating, upon determining that the voltage of the electric power supplied from the generator to the electric motor is greater than the electric motor induced voltage.

摘要： A vehicle driving force control apparatus is configured to provide a vehicle drive force control apparatus that can expand the operating region within which an electric motor can be driven in a stable manner. The output of an engine is delivered to the main drive wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to the electric motor and the output of the electric motor drives the subordinate drive wheels. When it is determined that the generator output voltage will not be sufficient to meet the requirement of the electric motor, the amount of acceleration slippage allowed at the left and front wheels is increased.

摘要： A vehicle driving force control apparatus is configured to provide a vehicle drive force control apparatus that can expand the operating region within which an electric motor can be driven in a stable manner. The output of an engine is delivered to the main drive wheels through a transmission and also to an electric generator. The output voltage of the electric generator is supplied to the electric motor and the output of the electric motor drives the subordinate drive wheels. When it is determined that the generator output voltage will not be sufficient to meet the requirement of the electric motor, the amount of acceleration slippage allowed at the left and front wheels is increased.
