Multi-mode control method and system of electronic control engine and crane with system

Abstract

The invention discloses a multi-mode control method of an electronic control engine, which is used for coordinating operating commands of all accelerator devices of automobile chassis engineering machinery. The method is carried out according to the following steps of: establishing a working relationship table corresponding to a working condition running state and an engine output state accordingto all accelerator devices and outputting the working relationship table to an electronic control unit of the electronic control engine; obtaining operating signals of all the accelerator devices; obtaining a judging result of the current working condition running state under the condition of the preset priority of all the accelerator devices; and outputting a corresponding control signal to the electronic control unit of the electronic control engine according to the judging result of the current working condition running state. The invention integrates power performance requirements of different operating conditions, thereby ensuring that the electronic control engine is reliably applied to the automobile chassis engineering machinery for fully exerting the advantages of the electronic control engine. The invention also discloses a multi-mode control system of the electronic control engine and an automobile crane with the control system.

Description

technical field [0001] The invention relates to the field of automatic control of engineering machinery, in particular to a multi-mode control method and system for an electronically controlled engine and a crane with the system. Background technique [0002] For the throttle control of the truck crane engine, it not only has the main throttle control of the conventional car, but also has the outrigger throttle and the vehicle throttle control, so as to adapt to the working conditions of the crane's outrigger operation and lifting operation. Different requirements for engine speed. [0003] The traditional automobile chassis construction machinery engine is a mechanical engine, and its characteristic curve is unique. Each throttle control is a mechanical flexible shaft linkage mechanism, and the engine speed is controlled by controlling the throttle swing arm of the engine. Taking the truck crane as an example, the output characteristics of the engine are the same under th...

Problems solved by technology

Therefore, if the traditional mechanical engine is used under the above three working conditions, it will inevitably cause insufficient power to cause the engine to stall or waste power.
