Lognormal Similarity Discrimination of Road Surface about ABS

To avoid it happening that the correctness of created model and developed simulation software on calculating the response time of ABS is partially verified by the experiment result, based on the structure of a typical ABS, the calculation models of the controllable characteristic and mechanical characteristic were created, and the simulation calculation software was developed. The current characteristic of the ABS is in real time detected on the computer simulation system, and the vehicular speed and the wheel speed were obtained. Especially, a lognormal similarity discriminate model of road surface was built. The model recognizes wheel speed data of theory and actual survey as the lognormal distribution while the first loop of anti-skid brake finish. When signals shape changed or noise interfered in the work, the model can classify and give right result. This model is benefit for batch produce, promote, renew and uphold of ABS.
