Example Embodiment

[0016] figure 1 Shown is a block diagram of the hardware structure of the device of the present invention, which mainly includes three parts: a signal sensing part, an information collection and control unit, and an alarm prompting unit. The contents of each part of the present invention will be further described below with reference to the drawings and embodiments.

[0017] 1. Signal sensing part

[0018] The signal sensing part is composed of a vehicle brake pedal displacement sensor and a vehicle brake pressure sensor. The two sense the displacement signal of the vehicle brake pedal and the vehicle brake pressure signal respectively, and convert them into voltage signals and output them to the information collection and control unit. .

[0019] In the embodiment of the present invention, the brake pedal displacement sensor adopts the linear displacement sensor of the model SENLIN5-500 produced by ISAAC Instrument Company, which has waterproof and dustproof characteristics...

Abstract

A vehicle brake effect motoring and alarm system belongs to the technical field of vehicle electron and safety. The outputs of a vehicle brake pedal displacement sensor and a vehicle brake pressure sensor are respectively connected with the input of an information collection and control unit; the output of the information collection and control unit is connected with the signal input of an alarm device. Due to being corresponding to the stroke of a brake pedal, the information collection and control unit carries out evaluation on the brake effect risk degree R of the vehicle according to a vehicle brake pressure signal BPact that is actually collected by the information collection and control unit as well as a benchmark brake pressure signal BPline2, and gives an alarm to a driver by transmitting a signal to an alarm device according to the evaluated risk degree R. The information collection and control unit is Motorola MC9S08DZ60. The vehicle brake effect motoring and alarm system improves the reliability of the system, has great help on preventing the traffic accidents caused by the losing and reducing of the brake effect, can adopt grading alarm according to the damaged degree of the brake performance, is simple in system structure, is easy to be achieved and has low cost.

Description

technical field [0001] An automobile braking efficiency monitoring and alarm system belongs to the technical field of automobile electronics and safety. Background technique [0002] The braking efficiency of automobiles is directly related to the safety of people's lives and property. To this end, GB 12676-1999 "Automobile Braking System Structure, Performance and Test Methods" puts forward clear and detailed structural requirements, braking system performance requirements and braking system test methods for automobile braking systems. The national standard puts forward corresponding requirements for various conditions that may reduce or lose the braking efficiency of the car, such as component breakage and brake wear. The signal light shall come on not later than the actuation control device". In order to meet the requirements of national standards, there are already some monitoring and alarm technologies for the failure of automobile braking efficiency. For example, pat...
