Problems solved by technology

However, since most of the customers are self-employed, they have insufficient understanding of the braking coordination of the main vehicle and the trailer, which leads to serious problems in the matching of the brakes of the main vehicle and the trailer, which in turn leads to frequent safety problems such as excessive wear of the friction lining and tire dragging.

Abstract

The embodiment of the invention provides a method and device for judging the brake consistency of a driving vehicle and a trailer, and relates to the technical field of vehicle braking systems. According to the method and the device, when a brake signal is received, the vehicle speed is calculated according to the acquired front axle wheel speed of the driving vehicle, the slip rate difference value of the driving vehicle and the trailer is calculated according to the vehicle speed, the acquired driving vehicle wheel speed and the acquired trailer wheel speed, and an alarm signal is generatedwhen the comparison result is that the slip rate difference value is larger than or equal to a preset safety threshold value. According to the method and the device, whether the braking of the drivingvehicle and the trailer is synchronous or not can be judged only by calculating the slip rate difference value of the driving vehicle and the trailer, the structure of the driving vehicle or the trailer is not required to be changed, the implementation cost is low, the application range is wide, the brake consistency of the driving vehicle and the trailer can be ensured, and the driving safety isensured.

Description

technical field [0001] The invention relates to the technical field of vehicle braking systems, in particular to a method and device for judging the consistency of braking between a main vehicle and a trailer, and a braking system. Background technique [0002] With the development of the economy and the progress of the society, the tractor has become the main means of transportation, which is mainly composed of the main vehicle and the trailer. Since the main vehicle and the trailer are produced by different manufacturers, when the tractor is braking, the brakes of the main vehicle and the trailer are not coordinated, which makes the vehicle very prone to dangerous accidents such as folding, rollover, steering failure, and cargo rushing out of the trailer. . [0003] In the prior art, in order to solve this problem, the relevant manufacturers mainly increase and adjust the ejector rod to the front of the trailer valve of the main vehicle, so as to release the aftermarket o...
