Abstract

The embodiment of the invention discloses a vehicle and an electronic stability control system, an exhaust method and an exhaust device thereof. The electronic stability control system ESC comprises amotor, a plunger pump, an oil supply valve, a pressure release valve and a pressure regulating valve, and the ESC is respectively connected with a brake cylinder and a brake wheel set through pipelines. The exhaust process of the ESC comprises at least one exhaust stage, and the exhaust stage comprises the steps that in the first sub-stage, a motor rotates to drive a plunger pump to conduct piston motion, an oil supply valve is opened, a pressure relief valve is closed, and a pressure regulating valve is opened, so that gas between the brake cylinder and the plunger pump is exhausted; and inthe second sub-stage, the motor rotates to drive the plunger pump to perform piston motion, the pressure release valve is opened, the oil supply valve is closed, and the pressure regulating valve is opened, so that gas between the brake wheel set and the plunger pump is exhausted. According to the ESC, the plunger pump is driven by the motor to perform piston motion, so that negative pressure is formed in the ESC, air in a pipeline, where gas is easy to store, in the ESC is exhausted, and the exhaust efficiency of the ESC and the stability of an ESC product are improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle safety, in particular to a vehicle and its electronic stability control system, exhaust method and exhaust device. Background technique [0002] With the development and popularization of the automobile industry, the stability of automobile chassis electronic products is also very important. Among them, the electronic stability control system (Electronic Stability Control, referred to as ESC) effect of liquid and exhaust is also paid special attention. [0003] At present, whether ESC products are on the whole vehicle or on the bench, they will first face the problem of liquid filling and exhausting. ESC product liquid filling and exhausting include conventional brake exhausting method, positive pressure method, and vacuum filling method. Exhaust method. In the conventional brake exhaust method, the brake fluid does not fill the entire ESC brake cavity, and there is gas in ...
