Road condition prediction method based on automobile driving characteristics

The invention provides an automobile driving characteristic-based road condition prediction method, which comprises the following steps that: a road condition characteristic judgment criterion number corresponding to typical road conditions is set and constructed according to national standard working conditions, and the typical road conditions comprise urban road conditions, urban unobstructed road conditions, mountain road conditions and expressway road conditions. And setting a criterion number range corresponding to the typical road condition, and constructing a corresponding relationship between the typical road condition and each criterion number. The method comprises the following steps: acquiring driving data of a vehicle, extracting a road condition characteristic criterion number from the driving data, and taking the extracted criterion number as a sample; setting an extraction period of criterion number samples, continuously extracting the obtained criterion number samples in the vehicle driving pr
