Travel trailer synchronous following braking control method considering delay characteristic of electromagnetic braking system

Abstract

The invention discloses a travel trailer synchronous following braking control method considering a delay characteristic of an electromagnetic braking system. Firstly whether a main car brake signal lamp is powered on or not is detected, if not, an electromagnetic brake is maintained to be switched off, if yes, a pre-braking torque signal is output to conduct pre-braking on a motor home; a main car braking deceleration is further detected, a following deceleration of the motor home is previewed and estimated according to the main car braking deceleration, a corresponding control signal is output to the electromagnetic brake, and thus braking operation of the motor home is achieved; and when the motor home is subjected to braking, the situation of switched on / off of the main car braking signal is synchronously monitored, and a following braking torque in the next moment is detected and previewed continuously, till the main car braking signal is cleared. The travel trailer synchronousfollowing braking control method can preview the main car braking deceleration in advance, and maximally overcomes the delay influence of the braking system so that the deceleration of the motor homecan be maintained to be consistent with that of a main car in real time, and accordingly more stable braking is achieved.

Description

technical field [0001] The invention relates to the technical field of brakes for a trailer-type caravan, in particular to a synchronous follow-up braking control method for a trailer-type caravan considering the delay characteristics of an electromagnetic braking system. Background technique [0002] With its flexible layout, complete home life configuration and the convenience of separation from the main car, the trailer-type RV has been widely welcomed in the European and American markets. With the continuous development of the domestic economy and the substantial improvement of people's living standards, RVs Will reflect the huge market potential in China. According to market research, at present, my country's trailer-type RV-related companies are largely at the end of the technology for foreign RV manufacturers and lack relevant technical property rights. Therefore, my country's technical reserves for trailer-type RVs urgently need to be improved. . [0003] Except for...

AI Technical Summary

Problems solved by technology

That is, when the braking deceleration of the main vehicle is used as the real-time tracking target to apply the corresponding braking signal to the RV, the braking response deceleration of the RV has a system lag compared with that of the main vehicle, which cannot achieve better real-time braking consistency
