摘要： In an electric motor drive system for an electric vehicle that includes a converter for performing direct-current voltage conversion and an inverter that converts the output voltage of the converter into alternating-current voltage, a control apparatus makes a required torque response determination to determine whether the electric vehicle is in a state in which high torque response is needed. Furthermore, in a drivability priority mode in which high torque response is needed, the control apparatus sets a voltage command value for the converter in a range where sine wave PWM control can be applied. On the other hand, in a fuel efficiency priority mode in which high torque response is not needed, the control apparatus sets the voltage command value for the converter such that power loss in the overall electric motor drive system is minimized, based on the operating state of an alternating-current electric motor.

摘要： In application of a square wave voltage to a motor MG2 to make the motor MG2 output a torque equivalent to a torque command Tm2*, the procedure of square wave control corrects reference phases ψb and −ψb as phases for maximizing an absolute value of the output torque of the motor MG2 with a rotational position detection error θerr and sets the results of the correction to an upper limit phase ψul and a lower limit phase ψll of the square wave voltage (step S110). A target voltage phase ψ* is set within a phase range defined by the upper limit phase ψul and the lower limit phase ψll, in order to reduce a torque difference between the torque command Tm2* and a torque estimate Tm2est (steps S120 and S130). An inverter 42 is controlled based on the target voltage phase ψ* and a rotational angle θ of the motor MG2.

摘要： A control unit of a rotary electric machine control system includes a stationary switching module and a transitional switching module. The stationary switching module switches over a control mode from a rectangular wave voltage phase control mode to an overmodulation current control mode by using a current phase of a smoothed current produced by filtering of high harmonic components on an actual current in a stationary operation state. The transitional switching module switches the control mode from the rectangular wave voltage phase control mode to the overmodulation current control mode by using the current phase of the actual current in a transitional operation state. The control mode is switched over by comparing the current phase of the actual current with a transitional switching reference line, which is preset separately from a switching reference line used for comparison with a current phase of the smoothed current.
