摘要： A motor control system includes a main control unit, a power supply unit, and a driving unit. The main control unit obtains sampling data of a motor and a power supply signal from the driving unit, generates a motor control signal according to the sampling data, and outputs a safety enable signal when determining that motor drive is abnormal according to the sampling data or when determining that power supply to the driving unit is abnormal according to the power supply signal. The power supply unit supplies power to the main control unit, monitors a state of the main control unit, and outputs a safety cut-off signal when the power supply unit or the main control unit is abnormal. The driving unit drives the motor according to the motor control signal, and switches to a safe path when receiving any one of the safety enable or safety cut-off signal.

摘要： A control device includes a limit value calculation unit that, when a rotary electric machine is driven as an electric motor, subtracts a power consumption value from a discharge power limit value of a power storage device to calculate an input limit value, and a control unit that, when the rotary electric machine is driven as an electric motor, controls the inverter so that a power consumption value of the rotary electric machine is equal to or less than the input limit value. In response to an abnormality occurring wherein a normal power consumption value cannot be achieved when the rotary electric machine is driven as an electric motor, the limit value calculation unit sets the power consumption value of the electrical device for calculating the input limit value on an upper limit side of a range in which the power consumption value takes when the electrical device is driven.
