Problems solved by technology

[0003] But at the same time, the dynamic state of the semi-trailer train composed of tractors and semi-trailers is open-loop stable when running in a straight line, but due to its own nonlinear, unstable, and uncertain factors, the semi-trailer train The dynamic state during reverse driving is open-loop unstable, prone to folding, collision, rollover and other unsteady state phenomena
It is difficult for those novice drivers with insufficient driving experience to complete the reversing task, and reversing accidents are prone to occur

Embodiment

[0061] Embodiment: This embodiment uses the control method of the present invention to carry out linear reversing induction control on a certain type of semi-trailer train, and the specific control process is as follows:

[0062] The basic technical parameters of this type of semi-trailer train are shown in the table below:

[0063]

[0064]

[0065] First, the driver's straight-line reversing demand is known from the reversing demand input button, and then the tractor reversing controllable range of the semi-trailer train of this type needs to be established first.

[0066] Adjust the semitrailer train so that the articulation angle is zero, and start reversing when the steering wheel is turned right to the 10° position. Stop until the velocity along the Y-axis at the center of mass of the trailer axle is greater than the velocity along the X-axis, and the hinge angle at this time is 70.53°; adjust the semi-trailer train again to make the hinge angle zero, and turn the ...

Abstract

The invention discloses an induction control method for semi-trailer train linear back off. According to the linear back-off requirements of a driver, the steering wheel rotation direction and rotation angle prompt is provided for the driver, and accordingly the driver is assisted in linear back-off operation completing. By means of the induction control method, the requirement for the back-off skill of the driver can be lowered, the back-off accidents are reduced, and meanwhile the back-off efficiency is improved.

Description

technical field [0001] The invention relates to the field of steering control of semi-trailers, in particular to an inductive control method for linear reversing of semi-trailer trains. Background technique [0002] In the past ten years, with the continuous improvement of the national road network, road transportation has become an important transportation mode in the comprehensive transportation system, and various types of transportation have the advantages of large load capacity, high transportation efficiency, good fuel economy and low transportation cost. Semi-trailer trains are getting more and more attention from the society and have become the main force of road freight worldwide. [0003] But at the same time, the dynamic state of the semi-trailer train composed of tractors and semi-trailers is open-loop stable when running in a straight line, but due to its own nonlinear, instability, uncertainty and other factors, the semi-trailer train The dynamic state during ...
