Accelerator switching method, system and construction machinery

Abstract

The invention discloses an accelerator switching method, system and engineering machinery. Among them, the throttle switching method is used for switching the throttle of construction machinery, including: judging whether the construction machinery needs a remote throttle to work; when the construction machinery needs a remote throttle to work, the throttle switching signal is sent to the engine by the controller through bus communication The electronic control unit of the electronic control unit controls the remote throttle to operate; when the construction machinery needs the main throttle to work, the remote throttle closing signal is sent by the controller to the electronic control unit of the engine through bus communication, and the electronic control unit controls the main throttle. Throttle action. The throttle switching mechanism of the present invention can better guarantee the driving and construction of construction machinery.

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
