An automobile intelligent thermal management domain control system capable of controlling multiple pump valves comprises a thermal management domain control device, a CAN communication interface circuit, an LIN communication interface circuit, a PWM communication interface circuit and a control circuit, wherein the CAN communication interface circuit, the LIN communication interface circuit, the PWM communication interface circuit and the control circuit are connected with the thermal management domain control device. The temperature of the motor and the liquid level position of the liquid storage container are monitored through the thermal management domain control device, so that over-temperature protection is achieved, the liquid level switch is controlled to be turned on and off, system inductance information is collected through the over-voltage protection module based on an internal channel of the AD collection module, over-voltage, over-current and over-temperature protection is achieved, and the reliability of the system is improved. A single controller can control N electric coolant pumps powered by a BLDC (brushless direct current) to realize pump speed control, and coolant control valves driven by a corresponding number of motors realize valve position control based on a request of an upper controller through a CAN (controller area network) bus.
