The invention discloses an automobile brake residual pressure control method and system, the automobile brake residual pressure control system comprises a pressure sensor, a first oil pumping device and a controller, and the pressure sensor is used for detecting a current pressure value in a brake pipeline in a brake system; the first oil pumping device is used for pumping oil of a brake pipelinein the brake system to the brake oil can, the controller is electrically connected with the pressure sensor and the first oil pumping device, and the control method of the automobile brake residual pressure control system is applied to the controller and comprises the steps that the current pressure value, detected by the pressure sensor, of the brake pipeline is received; and the received currentpressure value is compared with a first set pressure value, and when the current pressure value is larger than the first set pressure value and the automobile is in a normal running state, a first oil pumping device is controlled to pump oil in the brake pipeline into the brake oil can. Abrasion of friction plates in the brake is avoided, and driving resistance is reduced.

    本发明公开了一种汽车制动残余压力控制方法及系统,汽车制动残余压力控制系统包括压力传感器、第一抽油装置和控制器,压力传感器用以检测制动系统中的制动管路内的当前压力值,第一抽油装置用以将制动系统中的制动管路的油液抽至制动油壶,控制器与压力传感器和第一抽油装置电连接,汽车制动残余压力控制系统的控制方法应用于控制器,控制方法包括接收压力传感器检测制动管路的当前压力值,将接收到当前压力值与第一设定压力值进行比较,当当前压力值大于第一设定压力值且汽车处于正常运行状态时,控制第一抽油装置将所述制动管路中的油液抽至制动油壶,本发明能够降低制动管路的残余压力,避免了制动器内摩擦片的磨损,降低了行驶阻力。
