Abstract

The invention discloses a brake pipeline leakage detection method, an automobile electronic stabilization system and an automobile. The brake pipeline leakage detection method comprises the steps that current vehicle data of a target vehicle are collected, and a current working mode of a brake system is determined according to the current vehicle data; when the current working mode is a self-adaptive braking mode, active leakage detection is conducted on a braking pipeline, and a leakage detection result is obtained; and if the leakage detection result is that abnormity exists, controlling a vehicle instrument panel to carry out abnormity reminding. According to the method, leakage detection can be carried out on the brake pipeline without external force, that is, a driver does not need to step on the brake pedal, safety risks caused by hysteresis of leakage detection under the external force can be avoided, and the safety in the driving process is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a brake pipeline leak detection method, an automotive electronic stability system and an automobile. Background technique [0002] The brake pipeline of the brake system is mainly used to transmit the brake fluid in the brake master cylinder to the brakes of each wheel. If the brake pipeline leaks, the brake system will malfunction, thus affecting the safety of car driving. The existing brake pipeline leakage detection generally uses the brake fluid level sensor in the brake fluid tank to detect, but when the brake system has no external force, it is difficult for the brake fluid level sensor to detect the brake fluid level sensor in the brake fluid tank. When the dynamic fluid level is lower than the minimum value, only when the driver steps on the brake pedal, under the action of external force, the brake fluid level sensor can detect that the brake fluid level is too l...
