Problems solved by technology

[0003] However, when encountering a turning situation, the tractor turns first, and the semi-trailer is pulled by the tractor to change its direction. An angle will be formed, that is, the relative positional relationship between the center of mass on the semi-trailer and the center of mass of the tractor will change, which will easily lead to folding instability between the tractor and the semi-trailer, and low driving safety

Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0025] In one embodiment, such as figure 1 As shown, a power semi-trailer drive control method is provided, which can be applied to a power semi-trailer to control the drive of the power semi-trailer. Among them, the power semi-trailer is a semi-trailer with its own driving mechanism. Taking the method applied to the control device as an example for illustration, it includes the following steps:

[0026] S110: Obtain the steering wheel angle of the tractor connected to the power semi-trailer at the current moment, the real-time speed of the power semi-trailer, and the re...

Abstract

The invention relates to a power semitrailer driving control method, a control device, a medium and a power semitrailer system. The power semitrailer driving control method comprises the steps of obtaining the steering wheel rotating angle of a tractor connected with a power semitrailer at the current moment, the real-time speed of the power semitrailer and the real-time included angle between thetractor and the power semitrailer; determining a critical included angle corresponding to the current moment according to the real-time vehicle speed and the steering wheel angle; and if the absolutevalue of the real-time included angle is greater than the critical included angle corresponding to the current moment, reducing the output torque of a driving wheel of the power semitrailer. According to the invention, the driving safety of the traction type vehicle can be improved, and the operation stability of the whole vehicle is ensured at the same time.

Description

technical field [0001] The present application relates to the technical field of vehicle drive, in particular to a power semi-trailer drive control method, control device, medium and power semi-trailer system. Background technique [0002] A tractor vehicle refers to a vehicle including a tractor and a semi-trailer towed by the tractor, wherein the tractor and the semi-trailer are connected by a hinge, and the tractor and the semi-trailer are detachable, and are often used for cargo transportation. [0003] However, when encountering a turning situation, the tractor turns first, and the semi-trailer is pulled by the tractor to change its direction. During the turning process, an angle will be formed between the tractor and the semi-trailer, that is, the center of mass on the semi-trailer and the center of gravity of the tractor. The relative position relationship of the center of mass will change, which will easily lead to folding instability between the tractor and the semi...
