The invention discloses a vehicle brake temperature control device. The vehicle brake temperature control device comprises a temperature detection unit, a control unit, a temperature control feedbackunit and a result output module; the temperature detection unit is used for detecting the temperature information of the outer surface of a brake of a vehicle, the control unit is used for receiving related parameter information of the vehicle and the brake, road environment parameter information and the temperature information of the outer surface of the brake and obtaining the work temperature information of the brake and the temperature change amount of the vehicle in the brake process, the temperature control feedback unit is used for receiving the work temperature information of the brake, and on the premise that the work temperature information of the brake reaches the set temperature threshold value, the brake of the vehicle is cooled, and the result output module displays the temperature change amount. According to a brake temperature intelligent monitoring and cooling device, low cost, high practicability and feasibility and good implementation effect are achieved, in the vehicle brake process, the temperature can be monitored in real time, early warning is in time, the brake temperature is prevented from being too high, and the accident occurrence rate is reduced
