摘　　要：在现有ABS参考车速算法基础上,研究了一种实用的自适应算法。该算法基于轮速和压力控制状态信息,准确区分了每个控制循环,在每一控制循环结束时重新估算车身减速度,并据此估算下一控制循环的参考车速。编写了该参考车速自适应算法的程序,并用自行开发的ABS控制软件进行了实车道路试验。试验结果验证了参考车速算法的有效性,表明该算法满足ABS控制的要求。Based on the existing algorithms of vehicle reference speeds for ABS, an improved self- adaptive algorithm was investigated. This algorithm distinguished every control cycle exactly according to the information of wheel speeds and pressure control states. The vehicle deceleration was estimated at the end of each control cycle, and the reference speeds during the next cycle were determined according to the estimated value of deceleration. The codes of this self-adaptive algorithm was written and tested as part of the self-developed ECU of ABS through road tests. Test results show that this algorithm of reference speed is valid and can meet the demands of ABS control.
