1. A control system of an electric oil pump, the control system comprising: an electric oil pump, comprising: a pump unit, rotating to make oil flow; a motor, driving the pump unit; a motor control unit, exerting driving control on the motor; and a housing, accommodating the pump unit, the motor, and the motor control unit; and
a superordinate control unit, mounted to an application target to which the electric oil pump is applied, directly receiving detection information of a temperature sensor detecting a temperature of the oil, and communicating with the motor control unit to transmit a control command to the motor control unit based on the detection information,
wherein the motor control unit comprises a communication switching part that switches a communication circuit to directly receive the detection information of the temperature sensor when communication with the superordinate control unit is cut off, directly receives the detection information of the temperature sensor based on a switching signal of the communication switching part, and exerts driving control on the motor based on the detection information.
