Embodiment Construction

[0026] specific implementation plan

[0027] Such as figure 1 As shown in the air circuit of the retarder, the air brake circuit of the original car is completely controlled by the serial double-chamber air brake valve (1), the front brake relay valve (22), and the rear brake relay valve (6). Control, Park / Center Retarder Reservoir (2) only works when parked.

[0028] The increased air path divides the air from the tandem double-chamber air brake valve (1) to the rear brake chamber through the load-sensing proportional valve (20) into two paths, one path performs the rear wheel braking function, and the other path It is used as a control air path to send to the control port A of the differential relay valve (18). The air from the parking / central retarder air storage tank (2) is divided into two paths through the three-way pipe (21). The air supplied to the retarder air chamber is sent to the air inlet of the differential relay valve (18), and the other air is sent to the dif...

Abstract

The invention relates to an electromechanical ACBS (Anti-lock Central Braking System) retarder control device and its control method, which mainly includes air circuit control and electronic control, and the air circuit is equipped with a PCV regulating valve (16) on the original air brake circuit. The normally closed solenoid valve (19) acts as a control valve to control the air pressure of the retarder air chamber, and uses the parking air reservoir to complete the retarder air supply without affecting the original braking performance of the vehicle. The retarder is cooled by circulating cooling water, and the cooling water is recycled by the electric water pump (25). The central retarder control system can judge the driver's operation, prevent misoperation, and realize the real-time monitoring of speed, temperature and pressure, retarder brake anti-lock, CAN bus communication, display and alarm and other functions. The control of the PCV regulating valve (16) and the normally closed solenoid valve (19) is realized through the high-power drive module, and the ECU of the control circuit adopts ISP programming method, power management, hardware watchdog and other methods to ensure better stability of the controller sex.

Description

technical field [0001] The present invention relates to a control device and a control method of a novel electromechanical ACBS automobile retarder, more specifically refers to an air circuit and valve control device and its control method and an auxiliary brake control circuit, and is a kind of automobile brake control device. The pneumatic device and control circuit of the system. Background technique [0002] The retarder is a high-efficiency vehicle braking auxiliary braking device. It can not only make the vehicle slow and constant speed conveniently when driving on a slope, but also timely It can easily slow down, so it can greatly improve the safety and comfort of the car when driving. [0003] At present, the most commonly used auxiliary brakes for automobiles are generally electric eddy current retarders, hydraulic retarders, and exhaust brakes. Most of the eddy current retarder control adopts contact relay control and PWM pulse width modulation, while hydraulic a...
