The invention provides a control method for judging safe speed based on image identification infrared emission. The control method is characterized in that the control method comprises the following steps that 1, luminance decision parameters and infrared decision parameters are set in an ECU, and the luminance decision parameters comprise a rainy day road surface average luminance threshold, a snowy day road surface average luminance threshold and a frozen road surface average luminance threshold; 2, instant road surface images are obtained through a camera, then average luminance values of the instant road surface images are obtained through the ECU, the ECU compares the instant road surface average luminance values with each road surface average luminance threshold, and the belonging whether of the instant road surface is determined; 3, the infrared average reflection values of the instant road surface are obtained through an infrared transceiver and then is stored into the ECU; 4, the ECU obtains the safe speed MAX through a safe speed budget formula of (0.6X+0.4Y)*beta=K; and 5, according to the safe speed MAX of the instant road surface, and a car is controlled to be driven within the corresponding safe speed MAX.
Description
technical field [0001] The invention relates to the field of vehicle speed limit, in particular to a safe driving control method and system for detecting slippery road surface through image recognition. Background technique [0002] Traffic accidents have always accounted for more than 30% of the abnormal death rate of the population. [0003] In particular, the proportion of traffic accidents caused by wet and slippery roads caused by rainy days, snowy days and other weather conditions is even more prominent; even if drivers drive within the speed limit indicated by signs beside the road, they will still be caused by slippery roads. traffic accident. [0004] How to carry out vehicle safety speed limit in view of the instant road condition of vehicle driving is an urgent problem to be solved. Contents of the invention [0005] The purpose of the present invention is to overcome the deficiencies in the prior art, a safe driving control method for image recognition and de...
