1. A sliding mode trajectory voting strategy module, comprising: a fuzzification interface inputting a road curvature information and a road risk assessment information and performing a fuzzy analysis based on a plurality of predetermined membership functions; a fuzzy inference interlace integrating the road curvature information and the road risk assessment information based on a sliding mode control theory and performing a simulation on the road curvature information and the road risk assessment information to obtain a route voting result; and a defuzzification interface defuzzifing the route voting result according to a fuzzy logic rule table to obtain an orientation angle of a safe path.
