摘要： When the total value of demanded hydraulic power and demanded traveling power is larger than the sum of the engine power that can be output by an engine (1) and of the discharge power that can be discharged by an electrical storage device (3), the actual power of a hydraulic pump (9) is increased from the value at the time of demand toward the demanded hydraulic power under the constraint of a predetermined limit. While the power of the hydraulic pump is being subjected to the predetermined limit, the actual power of the traveling motor is decreased from the value at the time of demand by a value smaller than the magnitude of the predetermined limit. This prevents worsening of ride comfort attributable to the distribution of power between the hydraulic pump and the traveling motor.

摘要： An object of the present invention is to provide a controller of a field winding type synchronous motor that can stably output torque even if the d-axis current pulsates by reducing torque pulsation without causing fluctuations in the magnetic flux acting on the torque, and also provide an electric drive system, an electric four wheel driving vehicle, and a hybrid automobile. A motor control unit 100 performs control so that a desired torque 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 currents 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： A motor controlling device for mounting on a vehicle, which includes a controller capable of controlling a DC brushless motor at high response and high accuracy. The motor controlling device for mounting on the vehicle to drive the DC brushless motor comprises a main control section (120) for calculating a torque command for the motor, and a current control calculation section (140) constituted by a module or a dedicated LSI independent of the main control section (120). The current control calculation section (140) converts the coordinates of a current of the DC brushless motor into a d-axis direction, i.e., a direction of magnetic flux of a motor rotor, and into a q-axis direction orthogonal to the d-axis direction, and feedback-controls a current in the d-axis direction and a current in the q-axis direction separately.

摘要： An electric four-wheel drive vehicle includes: an internal combustion engine; a generator for outputting DC electrical power; an inverter for converting DC electrical power, output from the generator, into AC electrical power; and an AC electric motor, which is driven by the inverter, for driving rear wheels. An electric motor controller controls the inverter, the AC electric motor, and the generator, according to torque instructions from a vehicle. Furthermore, in a case that the output of the AC electric motor becomes negative, and excess electrical energy is generated, the electric motor controller controls the current applied to said AC electric motor such that the loss in said AC electric motor exceeds the negative output of said AC electric motor. This enables the AC electric motor to absorb excess electrical energy in the form of thermal loss.
