Title:
ENGINEERING MACHINE AND SUPPORT CONTROL METHOD, APPARATUS AND SYSTEM THEREFOR, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/105216
Kind Code:
A1
Abstract:
An engineering machine and a support control method, apparatus and system therefor, and a medium. The control method comprises: obtaining a target position input by a user at which an upper structure of an engineering machine works; calculating, according to the target position, upper structure attitude information under an optimal upper structure attitude, wherein the optimal upper structure attitude indicates an attitude under which a vehicle's center of gravity of the engineering machine is closest to the inner side, and the inner side indicates the side that a projection distance between the center of gravity of the upper structure and the center of gyration of the engineering machine is short; calculating, according to the upper structure attitude information, the vehicle's center of gravity corresponding to the optimal upper structure attitude; and calculating, according to the vehicle's center of gravity, a recommended support opening degree of support legs of the engineering machine, wherein the recommended support opening degree is configured so that the distance between a side line formed by supporting points of a corresponding support leg and the vehicle's center of gravity is less than a predetermined value, and the side line is located outside the vehicle's center of gravity. According to the support control method for an engineering machine, the recommended support opening degree required for the working of the upper structure can be obtained in advance, so that instructive suggestions are provided for support expansion.
