Abstract

The invention belongs to the technical field of vehicle gearboxes, and in particular relates to a control method of a vehicle gearbox and a control device of a vehicle gearbox. The control method of the vehicle gearbox of the present invention includes the following steps: monitoring the current state of the gear of the gearbox in the vehicle; in the control method of the vehicle gearbox of the present invention, the gearbox is in a neutral state, and the preset gear After the determination, the controller will pre-control the solenoid valves of the corresponding gears to operate. When the actual gear is shifted, the time for shifting gears can be saved, and at the same time, the driver's needs for starting in different gears can be met.

Description

Technical field [0001] The present invention belongs to the field of vehicle gearbox, and more particularly to a control method of a vehicle gearbox and a control device of a vehicle gearbox. Background technique [0002] With the development of industrialization, the demand for non-road vehicles is increasing, and people's performance requirements for non-road vehicles are also increasing, and the application of gearbox gear preset functions in non-road vehicles will continue to increase. [0003] The existing non-road vehicle, such as large bulldozers, the starting position is different, when the shift is required, when it is forward, it requires two files, the existing technology needs to be from the driver. Before entering a gear to the neutral file, then change from the empty file to the back file, it will waste more shift times, and it is inconvenient. [0004] Existing non-road vehicles will waste more shift times when they shift. Inventive content [0005] It is an objec...
