Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0016] figure 1 It is a flow chart of the engine throttle calibration method provided by the present invention. Such as figure 1 As shown, the present invention provides an engine throttle calibration method, the method comprising: receiving a throttle calibration command; obtaining an initial throttle rated voltage value corresponding to a throttle gear, and inputting the initial throttle rated voltage value into the engine's ECM (engine control module); receive the speed of the engine, and compare the speed with the target speed corresponding to the accelerator gear; when the absolute value of the difference between the speed and the target speed is greater ...

Abstract

The invention discloses an engine throttle calibration method and equipment as well as engineering machinery comprising the equipment. The engine throttle calibration method comprises the following steps of: receiving a throttle calibration instruction; inputting an initial rated throttle voltage value corresponding to a throttle gear to an ECM (Engine Control Module) of an engine; receiving a rotation speed of the engine and comparing the rotation speed with a target rotation speed corresponding to the throttle gear; when the absolute value of the difference between the rotation speed and the target rotation speed is more than a preset value, adjusting the initial rated throttle voltage value and inputting the adjusted rated throttle voltage value to the ECM to ensure that the absolute value of the difference between the rotation speed and the target rotation speed is less than the preset value; and replacing the initial rated throttle voltage value corresponding to the throttle gear with the adjusted rated throttle voltage value. Therefore, a user can complete the automatic calibration of the throttle by only inputting the throttle calibration instruction, thereby avoiding the poor maneuverability of an excavator caused by the influences of environmental factors such as temperatures and elevation.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to an engine throttle calibration method, equipment and engineering machinery including the equipment. Background technique [0002] Before the excavator leaves the factory, technicians will debug the voltage corresponding to the 10 throttle positions of the throttle knob and the corresponding engine speed, and manually calibrate the voltage of the 10 throttle positions of the throttle knob in the controller program, so that Each throttle gear can correspond to its rated speed. [0003] However, in practical applications, due to the influence of environmental factors such as temperature and altitude, the same throttle voltage will cause the engine to output different speeds, which will lead to poor maneuverability of the excavator. Contents of the invention [0004] The purpose of the present invention is to provide an engine throttle calibration method, equipment and enginee...
