Abstract

The invention discloses an alarm device of a hydraulic brake system and an alarm method. The alarm device comprises a pressure detector, a pressure data processor and an alarm, wherein the pressure detector is used for detecting the pressure loss of a pipeline of the hydraulic brake system; the pressure data processor is used for comparing the pressure loss which is detected by the pressure detector with the preset safe value, when the loss is larger than the safe value, the alarm indication signal is output; and the alarm is used for alarming in an indication way according to the alarm indication signal. Through detecting the pressure loss of the pipeline of the hydraulic brake system and comparing the pressure loss with the safe value, the hydraulic brake system is judged whether brake liquid seepage or leakage and other faults exist, the delayed alarm problem that the alarm only works when the liquid level descends to a certain scale limit in the prior art is solved, so a driver can judge the fault position within the shortest time, and the safety factor of braking for the integral vehicle is improved.

Description

technical field [0001] The invention relates to an alarm technology for a hydraulic braking system, in particular to an alarm device and an alarm method for a hydraulic braking system. Background technique [0002] In the automobile hydraulic braking system, it is necessary to give an alarm when the energy transmission device fails, so as to improve the safety performance of the automobile. [0003] In the prior art, the hydraulic braking system of the whole vehicle adopts the alarm device for the liquid level of the oil storage cup to alarm. Specifically, the liquid level alarm device includes an oil storage cup sensor and a buzzer. The oil storage cup sensor detects the liquid level in the oil storage cup assembly. When the liquid level drops to the preset dangerous scale line, the buzzer will The device will send an alarm to inform the driver that the energy transmission device is invalid, and remind the driver to take relevant measures. [0004] The defect of the prior...
