摘要： The present invention provides a motor controller capable of selecting a motor drive system that provides the best possible system efficiency, according to monitored parameters indicative of the vehicle condition and the conditions of the mounted components. A drive signal processing block of the motor controller outputs drive signals to the motor by using a first drive system and a second drive system causing less switching loss than the first drive system, depending on a demanded torque for the motor. A drive system determination block, when an operating point of the motor allows selection between the first drive system and the second drive system, performs switching from the first drive system to the second drive system, based on the condition of an electric component of the vehicle or the vehicle running condition.

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： 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.

摘要： When the torque command value is zero, a set point of DC current for an inverter is calculated to obtain a difference between the set point and a detected DC current so that an error in magnetic pole position may be estimated and corrected. By correcting the magnetic pole position, unwanted power running and regenerative torque of the motor can be avoided and unnecessary charge or discharge to or from a battery can be prevented.
