Problems solved by technology

In the existing control strategy, the torque output by the hydraulic drive axle is a fixed value. However, the torque of the mechanical drive axle changes gradually during the start-up process of the crane. The torque of the hydraulic drive axle and the torque of the mechanical drive axle do not match during the start-up process. It will lead to useless consumption of power between different power sources, thereby reducing the power and economy of the vehicle

Abstract

The embodiment of the invention provides a method for controlling a hydraulic auxiliary driving system, a processor, a crane and a machine readable storage medium. The method comprises the following steps: determining a first torque output by a mechanical drive axle of the crane; second torque output by the hydraulic drive axle is determined; and under the condition that the difference value of the first torque and the second torque is larger than the preset difference value, the torque output by the hydraulic drive axle is adjusted. By means of the technical scheme, it can be guaranteed that the torque output by the hydraulic drive axle and the torque output by the mechanical drive axle meet the set distribution relation, so that useless power consumption between different power sources is reduced, and the dynamic property and economical efficiency of the whole vehicle are improved.

Description

technical field [0001] The present application relates to the technical field of construction machinery, and in particular to a method, a processor, a crane and a machine-readable storage medium for controlling a hydraulic auxiliary drive system. Background technique [0002] Large cranes are mainly used in urban construction, bridges, wind power and other markets, covering plains, hills and mountains. With the rapid development of the market, users have put forward higher requirements for the dynamic performance of cranes during heavy-load transitions. The mechanical drive axle driven by the traditional chassis engine has exerted its maximum capability due to the constraints of conditions. Therefore, the hydraulic auxiliary drive system is used to drive the hydraulic drive axle. Providing additional power has become one of the main research directions. [0003] In the prior art, the hydraulic auxiliary drive system usually adopts an open-loop control strategy. After the ve...
