Abstract

In order to solve the impact of the estimated accuracy of automotive reference speed on logic threshold control method, automotive reference speed was estimated by using correctional peak-to-peak connection method, and an automotive ABS control strategy was put forward. In the strategy, automotive slip ratio was main control threshold and automotive acceleration was secondary control threshold. A control test was carried out on the road with high attachment coefficient. Test result shows that at 45 km · h-1, the curves of automotive reference speed and real speed match, the maximal error is 6.4%, and the average error is less than 1.6%. Automotive braking time is 3.2 s, the braking distance is 15 m, and the average deceleration is 3.9 m · s-2. Obviously, the control effect is good and the control strategy is credible.
