Abstract

The invention relates to a starting control method for a driverless caterpillar. The method comprises the steps that driving parameters of the driverless caterpillar are collected, the ramp slope and real-time ramp heading of the caterpillar on a ramp are calculated, and planning parameters of an upper computer planning system are obtained; on the basis of the collected driving parameters and the obtained planning parameters in the last step, autonomous recognition of starting working conditions is conducted; according to the autonomously recognized starting working conditions, corresponding starting control strategies are adopted for conducting starting of the caterpillar. An autonomous recognition method for the three working conditions of flat ground starting, in-situ steering starting and ramp starting is provided, starting control strategies corresponding to the three working conditions are provided, the slipping frictional power of a clutch is reduced in the control method, and the service life is prolonged. Accordingly, the starting problem of the driverless caterpillar is solved, the driverless demand of the caterpillar can be met, and the maneuverability of the caterpillar is brought into full play.

Description

technical field [0001] The invention relates to the technical field of unmanned driving, in particular to a starting control method of an unmanned crawler vehicle. Background technique [0002] Unmanned vehicles have entered a stage of rapid development. The control technology of unmanned vehicles can be divided into two types: passenger vehicles and special vehicles. Most scientific researchers and technicians have conducted research on the control technology of self-driving passenger vehicles, forming a research system for accelerator / brake control based on the traditional gasoline engine plus AT transmission / DCT transmission power transmission system. The research in this area has been fruitful, and various control algorithms have achieved good results on the basis of continuous improvement. [0003] With regard to the control technology of the automatic clutch, most researchers have used the AMT system as a platform to conduct research on the clutch automatic control te...
