基于轮速信息的ABS参考车速算法研究

Research on Reference Speed Algorithm of ABS Based on Wheel Speed Information

为了准确的估算出汽车ABS参考车速,根据ABS制动过程中轮缸压力和轮速的变化规律,提出了一种改进的参考车速综合算法,其关键是最大轮速峰值点是如何的确立。结果表明,该参考车速算法准确性好、适应性强。

In order to accurately estimate the automotive ABS reference speed, an improved reference speed synthesis algorithm is proposed according to the change law of wheel cylinder pressure and wheel speed during ABS braking, the key of which is how the maximum wheel speed peak point is established. The results show that the reference speed algorithm has good accuracy and adaptability.
