摘要： A controller of a field winding type synchronous motor is provided that can stably output torque even if the d-axis current pulsates by reducing torque pulsation without causing fluctuation in the magnetic flux acting on the torque. A motor control unit 100 performs control so that a desired torque can be generated from a field winding type motor 20 having a field winding 22f on the rotor. Based on a current Id flowing in the d-axis direction out of the current flowing in a stator winding 22a of the field winding type motor 20, the motor control unit 100 calculates an induced voltage Vf2 being induced in the field winding 22f and compensates a field voltage Vf of the field winding based on the induced voltage Vf2, thus suppressing pulsation of the field current flowing in the field winding of the field winding type motor 20.

摘要： An object of the present invention is to provide a controller for an electric four-wheel-drive vehicle, which is capable of minimizing torque changes and consuming excessive power even when the excessive power is generated by a generator. A motor control unit causes an AC motor to generate desired torque by controlling an inverter. When the power generated by the generator exceeds the power consumed by the inverter and AC motor to generate excessive power, a current command determination unit in the motor control unit consumes the excessive power by increasing a loss in the AC motor.

摘要： A vehicle drive unit, for quickly recovering a grip even if a wheel slips, in which in a slip state or at a time when the slip state is going to be generated, by pulsating a torque applied to the wheel, an angular velocity W of the wheel is changed so as to change the slip ratio S close to a slip ratio at which a friction coefficient becomes maximum, and thus, an average of a friction coefficient μ is enlarged and an average of a vehicle driving force F generated by a wheel is enlarged. Since the vehicle driving force is enlarged, the vehicle is accelerated and is easily gripped. Further, in a grip state or at a time of traveling at a high velocity, a vibration and an undesired sound are suppressed by doing away with the torque pulsation or making the fluctuation band of the torque pulsation small.

摘要： In a hybrid car, or an electric motor-driven four-wheel-drive vehicle, in which an electric motor is driven directly by an output from a generator, vehicle running performance is enhanced. The output from the generator is controlled so as to maintain a generator torque in a range, in which the vehicle does not stall. Specifically, a driving apparatus for the hybrid car includes a second generator 2 driven by an engine 1 for driving one pair of either front or rear wheels 14, 15, an electric motor 5 driven through directly receiving the output from the second generator 2 and driving the other pair of either the front or rear wheels 14, 15, and a four-wheel-drive control unit 6 controlling driving of the second generator 2 and the electric motor 5. When the engine 1 is in an overloaded condition, the four-wheel-drive control unit 6 limits the output of the second generator 2.

摘要： A vehicle drive train and drive train system is provided to simplify wire harness including power cables and reduce power loss in an engine-motor hybrid vehicle drive train system. The drive train and system includes some wheels driven by an engine, and other wheels driven by a motorized machine. When the running load is large, for example, starting a vehicle or running on a climbing lane, the motorized machine is activated for driving wheels in order to assist the engine. When no motor assistances is needed (for example, in low to medium load running or deceleration), the motorized machine functions as a generator to convert mechanical energy from the wheels into electric energy. The motorized machine, inverter, capacitor device and controller are integrated into a unit and the unit is attached to a differential gear.
