Problems solved by technology

[0007] The purpose of the present invention is to provide an intelligent control system and method of a hydraulic retarder, aiming at solving the problem that the current control system and method of a hydraulic retarder cannot meet the requirements of constant speed braking control when the car goes downhill. It is difficult to control the braking torque of the hydraulic retarder through a simple control method, and it is also difficult to make the system obtain better control accuracy

Abstract

The invention discloses an intelligent control system and method of a hydraulic retarder. The system comprises a hydraulic retarder driving wheel speed sensor,and the speed sensor is connected to a fuzzy PID controller of the hydraulic retarder and used for detecting the speed of a hydraulic retarder drive wheel and transmitting a detected speed signal of the hydraulic retarder drive wheel to the fuzzy PID controller of the hydraulic retarder; the fuzzy PID controller of hydraulic retarder is used for receiving the speed signal transmitted by the hydraulic retarder driving wheel speed sensor, conducting on-line self-tuning on the speed signal and then sending out a control command signal obtained after online self-turning. The slow-down effect of the system is continuous, and the driving safety is improved. Practice proves that the hydraulic retarder has a satisfying braking assisting effect, and becomes the first choice of high-grade and large-tonnage commercial vehicles.

Description

technical field [0001] The invention belongs to the technical field of retarder control, and in particular relates to an intelligent control system and method of a hydraulic retarder. Background technique [0002] The safety of automobiles has always been very important, especially in today's booming automobile transportation industry, which requires vehicles to have higher operating efficiency, so the vehicle's mass increases, the speed of the vehicle increases, and the kinetic energy of the vehicle increases exponentially. Due to the limitation of many factors, the braking capacity of the service brake cannot be improved synchronously. When braking continuously for a long time or at high speed down a long slope, the brake is subjected to a strong load that converts huge kinetic energy into heat energy. Brake linings and brake drums The temperature can be as high as 1000°C. At such a high temperature, not only the braking ability is reduced, but also the brake drum is easi...
