Abstract
Road identification is an important premise to the anti-lock function. The ABS control algorithm is put forward on the basis of the analysis of the ABS control process. Combining with the first pressurization time, the dropped wheel speed and the slope of the dropped speed at the end of decompression, a road identification method is put forward. The vehicle road test verification is conducted. The result indicates that the method can achieve real-time identification to various road conditions. (Author/publisher)
