Problems solved by technology

However, due to the slow response of the hydraulic system, the maneuverability of the engineering vehicle is reduced, and the energy consumption of the steering system is further increased after the introduction of the hydraulically driven steering trapezoid. The energy consumption of the entire hydraulic power steering system accounts for 10% of the energy consumption of the entire vehicle. %~15%

Embodiment Construction

[0063] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0064] It should be understood that terms such as "having", "comprising", and "including" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0065] The present invention is a differential cooperative steering system and a control method thereof for an all-wheel independent drive vehicle with steering trapezoidal steering and articulated steering. Preferably, the vehicle is driven by a hub hydraulic motor or an electric wheel. Therefore, applying this system to other articulated steerable vehicles capable of realizing all-wheel independent drive is not regarded as an innovation to the present invention. The system and its control method utilize the cooperation of the differential drive system and the original steering t...

Abstract

The invention discloses an all-wheel independent driving articulated vehicle differential cooperative steering system with articulated steering and steering trapezoidal steering, comprising: a front vehicle body and a rear vehicle body articulated by a connecting shaft; a hydraulic steering system, which is arranged between the front vehicle body and the rear vehicle body; a signal acquisition module arranged at a drive wheel for detecting drive wheel steering information; a differential cooperative steering system controller connected to a signal acquisition module for receiving detecting data of the signal acquisition module and making control decisions; a plurality of drive wheel motors respectively connected to the drive wheels for driving the drive wheels to rotate independently; a drive wheel motor controller connected with the differential cooperative steering system controller and a drive wheel motor for controlling the drive wheel to be independently driven. The invention alsoprovides a control method for the all-wheel independent driving articulated vehicle differential cooperative steering system with articulated steering and steering trapezoidal steering.

Description

technical field [0001] The invention belongs to the technical field of all-wheel independent drive articulated steering vehicle steering, and in particular relates to an all-wheel independently drive articulated vehicle differential cooperative steering system with both articulated steering and steering trapezoidal steering and a control method thereof. Background technique [0002] In recent years, with the increasingly serious environmental problems and the intensification of traditional energy shortages, automobiles have gradually developed towards the use of clean energy, among which electric vehicles have been developed to a large extent. With the gradual maturity of electric drive technology, and With the development and improvement of battery technology, engineering vehicles have also begun to adopt all-wheel independent drive technology powered by in-wheel motors or in-wheel hydraulic motors. Compared with the traditional centralized mechanical all-wheel drive mode, ...
