CONTROL DEVICE FOR ON-VEHICLE ELECTRIC COMPRESSOR

摘要

A control device for an on-vehicle electric compressor controls and drives an electric motor arranged in the on-vehicle electric compressor. The control device includes a temperature acquisition unit, a current detector, a threshold current value setting unit, and a motor current controller. The temperature acquisition unit acquires a temperature of the control device. The current detector detects a motor current, which is current that flows through the electric motor. The threshold current value setting unit sets a threshold current value in accordance with the temperature of the control device acquired by the temperature acquisition unit. The motor current controller controls the motor current based on a detection result of the current detector so that the motor current becomes less than or equal to the threshold current value.
