英文摘要：

The real-time and effective road automatic identification is important for the braking security of anti-lock braking system （ABS）. In this paper, the brake characteristics are analyzed; a new method that uses variational wheel velocity peak values to calculate vehicle reference velocity is proposed. Based on designing the fuzzy intelligent reasoning algorithms with the inputs of wheel deceleration and reference slip ratio, an adaptive reasoning method is studied, which can online adjust quantization factor and scale factor of fuzzy control by human simulation intelligent parameter modifying idea. Road test results show that compared to traditional logic gate algorithm, the fuzzy adap- tive algorithm is an effective new ABS road automatic identification method that has better braking stability and ada- ptiviness, which improves the response ability.
