Accelerator switching method, accelerator switching system and engineering machine

Abstract

The invention discloses an accelerator switching method, an accelerator switching system and an engineering machine. The accelerator switching method is applied to switching of an accelerator of the engineering machine and includes the steps of judging whether the engineering machine needs work of a remote accelerator or not, if needing, then sending an accelerator switching signal to an electronic control unit of an engine by means of bus communication through a controller and controlling the remote accelerator to work by the electronic control unit, and if the engineering machine needs work of a master accelerator, sending a remote accelerator off signal to the electronic control unit of the engine by means of bus communication through the controller and then controlling the master accelerator to work through the electronic control unit. With the accelerator switching system, driving and construction of the engineering machine can be guaranteed well.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an accelerator switching method, system and engineering machinery. Background technique [0002] With the great development of the national economy and urbanization, the demand for construction machinery is increasing day by day. This type of construction machinery uses the throttle to make the engine power the on-board unit. For the convenience of work, this type of construction machinery is often divided into main throttle (throttle inside the cab is defined as the main throttle) and remote throttle (throttle outside the cab is defined as remote throttle) to control the engine speed. The throttle is generally defined as the main throttle, and the action throttle that controls the on-board device is generally defined as the remote throttle; obviously, a good switching mechanism between the main throttle and the remote throttle can ensure the vehicle's rapid stability and sa...

AI Technical Summary

Problems solved by technology

[0003] At present, throttle switching requires a special throttle switching switch or signal, and the main throttle or remote throttle is selected through the switch. The problems of this method are: there are many and complicated switching circuit controls, and there are many fault points, which may easily cause the throttle to fail. The situation of switching is completed; and, when the accelerator is required, it is not easy to analyze whether the accelerator is not switched or the cause of the accelerator pedal
