Title:

EXCAVATOR THROTTLE CONTROL APPARATUS AND CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2023/226270

Kind Code:

A1

Abstract:

An excavator throttle control apparatus and control method. The apparatus comprises: a main controller (1), an engine control module (ECM) (2), an electronic monitor (3), a starting unit (4), a power supply relay (5), and an integrated switch panel (6); the integrated switch panel (6) effectively integrates a power-on switch and a throttle knob and is used for throttle gear control by means of operating switches, and transmitting a control instruction to the main controller (1); the main controller (1) is used for determining the rotating speed of an engine according to a gear control instruction sent by the integrated switch panel (6) and sending the gear control instruction to the ECM (2) to control the engine to execute a rotating speed of a corresponding gear. By using intelligent throttle control and using a composite key function, switching between throttle increase and decrease modes and fast throttle control are achieved, and the intelligence level of a machine is improved; by means of resettable increase and decrease of a knob gear, the problem of low reliability caused by multiple gears is reduced, and meanwhile, the operability is enhanced.
