Abstract

The invention discloses a full-automatic electric control gearbox control parameter calibration system and a loader, and relates to the field of engineering machinery, and the full-automatic electric control gearbox control parameter calibration system comprises a control parameter calibration method and a control parameter calibration system; through cooperation of the intelligent instrument and the matrix keys, the calibration request instruction is sent to the bus, after the gearbox controller receives the calibration request instruction, whether the current calibration condition is met or not is judged, and if the calibration condition is met, the gearbox control system is calibrated; the functions of displaying calibration conditions of the gearbox control system and calibrating parameters are realized; by means of the rotating speed sensor connected to the gearbox, rotating speed data output by the gearbox can be detected in real time, speed information can be processed in real time, whether a driver needs to be prompted to conduct calibration operation or not is judged according to the jerk value, and therefore control parameters of a control system can be corrected in time; and the situation of gear shifting impact in the gear shifting process is avoided, and the experience feeling of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a control parameter calibration system for a fully automatic electronically controlled gearbox and a loader. Background technique [0002] The transmission is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in fixed or stepwise steps, also known as the gearbox. Speed ​​changer is made up of speed change transmission mechanism and operating mechanism, and some automobiles also have power output mechanism. Most of the transmission mechanisms are driven by ordinary gears, and some are driven by planetary gears. Ordinary gear transmission transmission mechanisms generally use slip gears and synchronizers. The electronically controlled planetary gearbox of the loader adopts the controller TCU to control the proportional solenoid valve to realize the gear shifting of the gearbo...
