重型越野汽车电控制动系统的设计与仿真

摘要

For reducing the braking response time and improving the braking performance of heavy off-road vehicle, an electronically controlled brake system ( EBS) for pneumatic braking is designed. Based on the perform-ance parameters of target vehicle and EBS control algorithm with Matlab/Simulink as simulation platform, models for target vehicle and control alroithm are built to simulate the braking performance of EBS designed in different working conditions, which are then compared with the test data of conventional ABS system, verifying the rationality of sys-tem designed. The results show that the EBS designed has obvious advantages in reducing brake response time and enhancing braking safety.%为缩短重型越野汽车的制动响应时间，提高制动性能，设计了基于气压制动的电控制动系统( EBS)。依据目标车型的性能参数及EBS控制算法，以Matlab/Simulink为仿真平台，建立了目标车型的整车模型及控制算法模型。仿真研究了所设计的EBS系统在不同工况下的制动性能，并通过与常规ABS制动系统试验数据的对比，验证了系统设计的合理性。结果表明，所设计的EBS系统在减少制动响应时间和提高制动安全性方面具有明显的优势。
