Abstract

A steering control method for a trailer includes firstly, controlling steering of front wheels of a tractor and acquiring deflection angles theta 1 of inner steering front wheels of front wheels of the tractor and an included angle alpha between a longitudinal central vertical plane of the tractor and a longitudinal central vertical plane of the trailer; and secondly, controlling steering of other pairs of steering wheels of the trailer, so that deflection angles of various other inner steering wheels on the tractor meet an inequality of arctan [(Li / L1)Xtan(theta 1)-3 degrees]< / =theta i< / ={arctan[(Li / L1)Xtan(theta 1)]+3 degrees, and deflection angles of various inner steering wheels on the trailer meet an inequality of [alpha-arctan(Z / P)-3 degrees]< / =theta j< / =[alpha-arctan(Z / P)+3 degrees]. The invention further provides a controller, the trailer and a steering system of the same. The steering control method, the controller, the trailer and the steering system have the advantages that the various wheels of the trailer can at least rotate around the same steering central area, abnormal abrasion to tires is obviously relieved, and the steering stability and the passing ability of the trailer are improved.

Description

technical field

[0001] The invention relates to a vehicle steering method, in particular to a steering control method of a trailer. Meanwhile, the present invention relates to a controller that can be used in the steering control method of the trailer. Further, the present invention relates to a trailer steering system for implementing the trailer steering control method. In addition, the invention also relates to a trailer comprising the steering system of the trailer. Background technique

[0002] Trailers are mainly used for long-distance transportation or special equipment transportation. As the volume and weight of these vehicles increase, especially the increase in the length of the vehicle, the requirements for the load capacity and the overall wheelbase of the vehicle are increasing.

[0003] Typically, trailers are mainly divided into full-trailer trailers and semi-trailer trailers, for example, see figure 1 with figure 2 As shown, the full-trailer trailer is ...
