Abstract

The invention discloses a method and a device for automatically recognizing snow terrain pattern of a vehicle. The method comprises the following steps: 1. An electronic stabilization system (3) of the vehicle, an engine (4), a transmission (5) and an electric power assisted steering system (6) send vehicle information to a terrain automatic recognition module (1); 2, that automatic terrain recognition module judge whether the terrain recognition condition are satisfied, if the terrain recognition conditions are satisfied, the step 3 is execute, if the terrain recognition conditions are not satisfied, the terrain pattern judgment is not made, and the step 1 is returned; 3, that automatic terrain recognition module judge whether one of the two condition of snow mode driving is satisfied, ifso, executing the step 4, if not, do not make the terrain mode judgment, and return to the step 1; and 3, the automatic terrain recognition module judges whether one of the two conditions of snow mode driving is satisfied. Step 4: the ATC system confirms that the setting parameter M=Msnow, and the vehicle driving control mode is adjusted to the snow driving mode. The invention can automatically recognize the snow pattern when the vehicle is traveling on the snow road, and manual intervention is not required.

Description

technical field [0001] The invention relates to the field of vehicle drive control, in particular to a method and device for automatic recognition of vehicle snow terrain patterns. Background technique [0002] Some vehicles are now equipped with a terrain control system. This system will adjust the driving state of the vehicle according to the characteristics of the terrain to improve the vehicle's adaptability to driving on different roads, so that it can reduce the requirements for the driver's driving skills in complex terrain conditions and improve the performance of the vehicle. Comfort, passability and other aspects of ability. However, the current terrain control system on the vehicle requires the driver to first identify the terrain and confirm the terrain mode, such as: ice, snow, sand, mud or rocks, etc., and switch the terrain mode control switch to the corresponding gear, so that the vehicle can perform the relevant terrain mode. control. The control system in...
