Problems solved by technology

[0004] Due to the soft characteristics of mining machinery operation roads and complex road conditions, it is difficult to identify
At present, in terms of road surface recognition, the main road surface is mainly recognized based on the road surface adhesion coefficient, and other parameters of the road surface are used for auxiliary recognition. Failure to consider the reliability of identification results and failure to make full use of identification data with insufficient reliability
This will seriously affect the reliability of road surface recognition, and it is also an underutilization of road surface recognition data
