Problems solved by technology

[0004] There are still some potential safety hazards in the existing electric vehicle braking methods, especially when the electronic control system fails, the following consequences will occur, which greatly threatens the safe driving of the vehicle
[0005] 1. Most of the existing air brakes of electric vehicles adopt electronic control. If the electronic control devices are aging, interfered by high-voltage circuits and contact sintering and other faults, the continuous operation of the air compressor will cause the pipeline pressure to be too high, resulting in motor overload and burning and damage to pipes and components, and increased battery consumption
[0006] 2. The air brake of the existing electric vehicles is mostly started by the air compressor with load, which will increase the starting current and easily cause the motor to burn out

Embodiment Construction

[0016] The accompanying drawings show a specific embodiment of the present invention, and the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] by attaching figure 1 It can be seen that the present invention is an air braking system for automobiles, including a brake pedal 1, a front brake cylinder 2, an air compressor 9, a rear brake cylinder 10 and a main air supply pipeline 11, and its characteristics are: In the dynamic system, an air compressor start / stop control system 4 is set, through which the air compressor start / stop control system 4 realizes the intermittent work of the air compressor 9 within the set working pressure range. The control system 4 is composed of a pressure regulating valve 3, a pressure relay 5, a relay 6, a solenoid valve 7 and an air control directional valve 8, and uses the pressure regulating valve 3 and the pressure relay 5 to start / stop the air compressor. At the ...

Abstract

An air brake controlling method and system for electric car is disclosed. An air compressor starting/stopping control system is arranged in the air brake control system for making the air compressor work in preset pressure range. When the air compressor is stopped, the electromagnetic valve and pneumatic direction valve are used to unload the energy supply loop and discharge pollutant, ensuring that the air compressor is started in idle state.

Description

technical field [0001] The present invention relates to a braking control method of an automobile, in particular to a braking control method of an electric automobile; the present invention also relates to a braking control system of an automobile, in particular to a braking control system of an electric automobile . It is mainly used in the air brake of electric vehicles, and can also be used in the air brake of other vehicles. Background technique [0002] The automobile braking device is an important system to ensure the safe operation of the automobile, and the quality of the automobile braking device will directly affect the safety performance of the automobile. The brakes of traditional internal combustion vehicles mainly include air brakes and hydraulic brakes. Among them, the air brake is completed by the air compressor system driven by the automobile engine. The air compressor is directly driven by the engine. The air compressor operates for a long time and adopts...
