Embodiment Construction
[0022] The present invention will be described in detail below in conjunction with the implementations shown in the drawings, but it should be noted that these implementations are not limitations of the present invention, and those of ordinary skill in the art based on the functions, methods, or structural changes made by these implementations Equivalent transformations or substitutions all fall within the protection scope of the present invention.
[0023] Such as figure 1 As shown, the automobile retarder control method of the present invention comprises the following steps:
[0024] S1. When the ABS is working, send an ABS working status message;
[0025] S2. Read the ABS working status message, and process the ABS working status message;
[0026] S3. When the processing result in step S2 shows that: when the speed of the vehicle is ≥ 5Km / h and the ABS working state is OFF, then supply power to the retarder control box, control the retarder to work, and execute step S4; ...

The invention provides an automobile retarder control method and system, wherein the method comprises the steps of S1, during operation of an ABS (anti-lock braking system), sending an ABS working state message; S2, reading the ABS working state message, and performing processing for the ABS working state message; S3, when the processing results of step S2 show that velocity of the automobile is > / =5 Km / h and ABS working state is OFF, electrifying a retarder control box to control a retarder to operate, and executing the step S4; S4, reading an engine throttle openness message, and performingprocessing for the engine throttle openness message; S5, when the processing results of step S4 show that throttle openness is greater than 5% of total openness, cutting off power to the retarder control box, and controlling the retarder to stop operating. The automobile retarder control method has the advantages that a speed sensor can be omitted, fewer rigid wires are used, the cost is lowered,failure rate can be reduced, and equipment stability and anti-interfering capacity are improved.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile retarder control method and system. Background technique [0002] At present, the working state control of automobile retarder is realized by hard wire. When the ABS is working, the vehicle control box outputs a signal, and then combines the output signal of the speed switch installed on the vehicle to control whether the retarder works through the relay. The above-mentioned control method has a long hard line, is easy to interfere, has a lot of materials, and costs a lot. It does not meet the requirements for the development of automotive electronic information. Therefore, how to reduce interference and improve work stability is a problem to be solved by the present invention. Contents of the invention [0003] The object of the present invention is to provide a method and system for controlling an automobile retarder, so as to overcome the problems existi...
