specific Embodiment 1

[0050] The control method during the application of a kind of automatic parking system based on air brake described in specific embodiment 1 is as follows:

[0051] (1) When the panel working mode indicators on the first self-resetting switch 51a and the second self-resetting switch 51b are always on, it is in the fully automatic mode, and the system functions as automatic parking and electronic handbrake.

[0052] Automatic parking function: when the ECU controller 3 in the system detects that the engine is working, the gear is in neutral, the accelerator is fully released, and when the vehicle speed is zero, the second dual-control two-position five-way solenoid valve 42 is triggered The left coil 43 is energized, the handbrake chamber 1 communicates with the air outlet port A2 of the second dual-control two-position five-way solenoid valve 42, and the air outlet port A2 of the second double-control two-position five-way solenoid valve 42 communicates with the air inlet port ...

specific Embodiment 2

[0067] A kind of control method based on the automatic parking system of air brake described in specific embodiment 2:

[0068] (1) When the panel working mode indicator lights on the first self-resetting switch 51a and the second self-resetting switch 51b are always on, they are in fully automatic mode, and the system plays the functions of automatic parking and electronic handbrake;

[0069] Automatic parking function: the ECU controller 3 in the system receives the electronic signal when the engine is working, the gear is in neutral, the accelerator is fully released, and the vehicle speed is zero, triggering the second double-control two-position three-way solenoid valve 45 The left coil 43 is energized, and the high-pressure gas in the handbrake chamber 1 communicates with the air outlet port A2 of the second dual-control two-position three-way solenoid valve 45, and the air outlet port A2 of the second double-control two-position three-way solenoid valve 45 communicates w...

Abstract

The invention relates to an automatic parking system and method based on pneumatic braking. The system comprises a hand braking air chamber, a hand braking air cylinder, an ECU controller, an air path control assembly and a mode conversion control assembly. The hand braking air chamber is connected with the air path control assembly. The input end of the ECU controller is connected with an automobile conversional circuit or a CAN bus module, and receives engine rotating speed signals, mileage signals, accelerator signals and gear signals. The output end of the ECU controller is connected with the air path control assembly and the mode conversion control assembly through wiring harnesses respectively. The air path control assembly is connected with the ECU controller through a wiring harness. The air path control assembly is connected with the hand barking air chamber and the hand braking air cylinder through air pipes respectively. The mode conversion control assembly is connected with the air path control assembly through an air pipe. According to the automatic parking system and method based on pneumatic braking, the actions are automatic and intelligent, the automatic control level of the whole vehicle is effectively improved, and the traveling and parking safety is greatly improved.

Description

technical field [0001] The invention relates to an air brake-based automatic parking system and a method thereof, belonging to the technical field of automobile parking brakes. Background technique [0002] Now on the market, cars that use brake fluid as the brake medium, such as cars and small station wagons, use complex electronic control methods to realize the application of automatic parking function (AUTOHOLD) and electronic handbrake (EPB) functions. Most of them The integrated front and rear wheel brake calipers are controlled by the on-board computer or the related components of the advanced ESP (Electronic Stability System) are executed. The cost of parts is very high, so this function is generally only configured in high-end mid-range cars with high prices. superior. The vehicles that use high-pressure air as the braking medium are mainly large and medium-sized passenger cars and trucks, and because the working principle and control method of the brakes are basica...
