A motor control system includes: a converter; two inverters; two alternating-current motors; and a control unit. The control unit is configured to control the system voltage by feedback of a current phase of a current vector of motor current of each of the motors on a d-q coordinate plane so that rectangular wave control of at least one of the first and second motors is performed in a state where the current phase is an optimal current phase, wherein the control unit selects, as a subject of the feedback, the current phase of one of the motors that is larger than the other motor in system voltage deviation obtained based on the current vector.

A motor control system includes: a power supply; a converter; an inverter; an alternating-current motor; and a control unit that drives the motor in any one of sinusoidal PWM control, overmodulation control and rectangular wave control through operation control of the converter and the inverter. The control unit starts step-up operation of the converter when a current vector of motor current of the motor on a d-q coordinate plane becomes a current phase corresponding to motor torque, at which a system loss is equal between before and after starting the step-up operation, while the control unit supplies the direct-current voltage, supplied from the power supply, to the inverter without stepping up the direct-current voltage by the converter and performs the rectangular wave control of the motor in a state where the current phase is an optimal current phase.

摘要:
A control device includes a PWM control unit that executes PWM control over an alternating-current motor mounted on a vehicle. The PWM control unit includes an alarm sound generation processing unit that executes an alarm sound generating process of generating an alarm sound from the motor for informing a pedestrian, or the like, of the approach of the vehicle by intentionally varying phase current flowing through the motor by periodically adding a variation value (ΔV) to a d-axis voltage command value (Vd) at a predetermined interval. At the time of executing the alarm sound generating process, the alarm sound generation processing unit adjusts the variation value (ΔV) such that the d-axis voltage command value (Vda) resulting from the alarm sound generating process (the sum of Vd and ΔV) falls within a range in which it is possible to suppress occurrence of an overcurrent in the motor.
