Problems solved by technology

However, in this way, the first is that the main shaft will always drive the pump to rotate, which will increase the power in the non-working state; the second is that the proportional valve for controlling the pressure of the variable displacement pump requires higher precision, resulting in higher cost

Embodiment 1

[0031] This embodiment provides a control system for a hydraulic retarder, including a hydraulic pump 2, a motor 1, a first pressure sensor, a second pressure sensor and a controller; such as figure 1 As shown, the motor 1 is connected with the hydraulic pump 2, which is used to provide a power source to make the hydraulic pump rotate to generate pressure, and push the working fluid into the working chamber of the hydraulic retarder. The hydraulic retarder controls the pressure and realizes the control of the working torque of the hydraulic retarder;

[0032] The hydraulic pump 2 is connected to the oil inlet 6 of the hydraulic retarder through the liquid inlet pipeline 4, and the working fluid 10 in the liquid storage tank 3 is input into the working chamber of the hydraulic retarder through the oil inlet 6, and the working fluid 10 enters the hydraulic retarder. Between the stator 11 and the rotor 12, the rotor 12 and the gear 13 are connected coaxially (main shaft), and the...

Embodiment 2

[0075] This embodiment provides an intelligent control system for hydraulic retarder, such as Figure 4 shown, including:

[0076]A demand judging device 1 is used for judging whether the hydraulic retarder is required to provide the working torque required for braking; when not required, the status quo is maintained;

[0077] A quick-start device 2 is used to quickly start the hydraulic retarder when the hydraulic retarder is required to provide the working torque required for braking;

[0078] The neural network prediction device 3 is used to use the fuzzy cerebellum model neural network to deduce and predict the required motor speed according to the input operating environment parameters of the control system of the hydraulic retarder, so as to adjust the outlet pressure of the hydraulic pump to the optimal value , to realize the real-time intelligent control of the working torque required by the hydraulic retarder. Preferably, the operating environment parameters include...

Abstract

The invention discloses an intelligent control method and system for a hydraulic retarder and a program product, and relates to the technical field of intelligent control over the hydraulic retarder. The method comprises the steps that when the hydraulic retarder needs to provide working torque needed by braking, the hydraulic retarder is rapidly started; a fuzzy cerebellar model neural network is adopted, according to input operating environment parameters of a control system of the hydraulic retarder, deduction and prediction are carried out to obtain the required motor rotating speed, the outlet pressure of a hydraulic pump is adjusted to the optimal value, and real-time intelligent control over the working torque required by the hydraulic retarder is achieved. According to actual operating environment parameters, by intelligently controlling the rotating speed of the motor, the outlet pressure of the hydraulic pump can be rapidly changed, optimal control over the working torque needed by the hydraulic retarder is achieved, a vehicle can safely and stably run, and the intelligent control degree is improved.

Description

technical field [0001] The invention relates to the technical field of intelligent control of hydraulic retarders, in particular to an intelligent control method, system and program product of a hydraulic retarder. Background technique [0002] A hydraulic retarder is an automotive retarder that reduces the speed of a vehicle through a hydraulic device, usually including a stator, a rotor, a liquid inlet pipe, a liquid outlet pipe, a liquid reservoir, a radiator, and the like. The stator and the rotor are respectively equipped with vanes, and are arranged oppositely and placed in the casing to form a working cavity, and the working cavity is filled with working fluid through an external circulation loop to generate a braking force. When the rotor moves, it drives the working fluid to move and decelerates on the stator, thereby generating a braking torque on the rotor and transmitting the braking torque to the wheels, thereby generating a braking effect and assisting the brak...
