Multifunctional braking alarm control system and method

Abstract

The invention belongs to the technical field of automobile braking systems, and discloses a multifunctional braking alarm control system and method. In the braking process, braking hydraulic pressureacts on a braking pad to generate frictional force, and braking is achieved; heat is generated through friction, so that the temperature of the braking pad is increased, through temperature changing,a resistance value of a temperature sensor is changed and transformed into an electrical signal, and the braking situation is reflected. When the temperature is changed abnormally, the signal is transferred to a single chip microcomputer processor, and alarming is conducted; when the braking pad is rubbed and worn to a limit position, a sensing line is rubbed so that bonding can be conducted on the sensing line and a braking disc, the signal is transferred to the single chip microcomputer processor, and alarming is conducted; and when the system pressure is over low, alarming is conducted. According to the multifunctional braking alarm control system and method, braking is effectively monitored, alarming is conducted on the braking pad which is worn to the limit, alarming is conducted whenthe braking pad is overheated in the locking process of a braking system, the braking hydraulic pressure is monitored, the braking pressure is displayed, when the pressure is insufficient, alarming is conducted, and a driver is reminded through alarming.

Description

technical field [0001] The invention belongs to the technical field of automobile brake systems, and in particular relates to a multifunctional brake alarm control system and a control method. Background technique [0002] The braking system mainly applies the working principle of friction, using the friction between brake pads and brake discs (drums) and tires and the ground, to convert the kinetic energy of the vehicle into heat energy after friction, so as to realize deceleration and parking, which is very important to the safety of driving. effect. The brake pad sensor acts on the brake system to help drivers judge the wear of the brake pads, facilitate timely maintenance and ensure the normal and stable operation of the brake system. At present, the technology pays attention to alarming the brake pads whose wear reaches the limit, which can control the hydraulic pressure of the system and prevent locking, but the problem of alarming the mechanical jamming of the brake ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems in the existing technology are: the existing brake system only alarms the brake pads when the wear reaches the limit; there is no brake pad temperature sensor and pressure sensor in the structure; there is no process detection sensor, and process control cannot be realized; There is no brake fluid pressure sensor, and when the braking system fails, it cannot alarm in time, posing a safety hazard; there is no brake pad temperature sensor and pressure sensor in the structure; when the braking system reports failure, the brake pads will overheat and the brake will fail. Failure to report in time, discovery and alarm in time, posing potential safety hazards
