specific Embodiment 2

[0104] Of course, in other embodiments, the step of determining the preset slip condition corresponding to the wheel assembly in accordance with the size relationship of the reference average speed coefficient and the preset low speed speed coefficient. DETAILED DESCRIPTION OF THE INVENTION

[0105] The comparison reference average speed coefficient and the preset low speed speed coefficient, when the current is large, the corresponding first slip rate is selected as the allowable sliding rate, otherwise, each wheel assembly selects the corresponding second slip rate as a corresponding second slip rate. Allow slip rate;

[0106]The preset slip condition corresponding to the wheel assembly is that the speed difference coefficient of the wheel assembly is greater than the corresponding allowable sliding rate, and if so, the wheel assembly satisfies the corresponding preset slip condition.

[0107] That is, in the second embodiment, after determining the vehicle speed, the speed diff...

Abstract

The invention discloses a vehicle anti-skid control method and system. The control method comprises the steps: obtaining speed coefficients of wheel assemblies, wherein each wheel assembly is correspondingly connected to one electric proportional hydraulic motor; using the average value of the speed coefficients of all the wheel assemblies as a reference average speed coefficient; obtaining the speed difference coefficient of the wheel assembly, wherein the speed difference coefficient of the wheel assembly is the difference value between the speed coefficient of the wheel assembly and the reference average speed coefficient; and judging whether the wheel assembly slips or not according to the speed difference coefficient of the wheel assembly, and if yes, reducing the displacement of the electric proportional hydraulic motor connected with the wheel assembly. According to the method, speed reduction control is conducted on the wheel assembly with the slipping problem, speed reduction of the wheel assembly is achieved by reducing the motor displacement of the electric proportional hydraulic motor connected with the wheel assembly, additional valve sets can be reduced, the cost is reduced, and the working efficiency of the hydraulic system is improved.

Description

Technical field [0001] The present invention relates to the field of vehicle engineering technology, and more particularly to a vehicle anti-slip control method and system. Background technique [0002] At present, in some vehicles, the anti-slip method is mainly to increase the flow distribution in the system to increase the split set flow valve, the anti-skid valve, thereby keeping the rotational speed of each motor to the purpose of non-slip. This method is due to the addition of the valve set, the cost is high, and the heat generation of the hydraulic system is increased due to throttling loss, and the system has low efficiency. [0003] Therefore, how to reduce costs, improve system work efficiency, is a technical problem that will be solved by those skilled in the art. Inventive content [0004] In view of this, it is an object of the present invention to provide a vehicle anti-slip control method and system capable of reducing cost and improving system work efficiency. ...
