Abstract

The invention belongs to the technical field of vehicle gearboxes, and particularly relates to a control method of a vehicle gearbox and a control device of the vehicle gearbox. The control method ofthe vehicle gearbox comprises the following steps that a current state of a gear of the gearbox in the vehicle is monitored; according to the control method of the vehicle gearbox, the gearbox is in aneutral position state, after a preset gear is determined, a controller can pre-control a solenoid valve of the corresponding gear for action, when gear shifting is actually carried out, the gear shifting time can be saved, and meanwhile, the demand of a driver for starting different gears is met.

Description

technical field [0001] 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. Background technique [0002] With the development of industrialization, the demand for non-road vehicles continues to increase, and people's performance requirements for non-road vehicles also continue to increase, and the application of the gearbox gear preset function in non-road vehicles will also continue to increase. [0003] Existing off-road vehicles, such as large bulldozers, have different starting gears under different working conditions. When shifting gears, the first gear is needed when moving forward, and the second gear is needed when going backward. The existing technology is that the driver needs to start from Moving one gear forward and shifting to neutral gear, and then changing from neutral gear to backward second gear, will waste more gear shifting time, and...
