制动系统支持高阶驾驶自动化功能系统设计的几点讨论

Design of Chassis Brake System Supporting Highly Autonomous Driving System

高阶驾驶自动化功能,对底盘制动系统提出了较高的系统要求;常规的ABS/ESP很难满足高阶驾驶自动化的冗余安全需求。文章在分析底盘制动系统各电子控制单元的原理及局限性基础上,对比设计多种方案的优劣性,深入讨论了不同等级驾驶自动化系统对底盘制动系统的需求,并进行了总结,为不同类型的高阶驾驶自动化的底盘制动选型提供了参考。

The highly autonomous driving(HAD)function puts forward higher system requirements for the chassis braking system;conventional ABS/ESC is difficult to meet the redundant safety requirements of HAD System.Based on the analysis of the principle and the limitation of each electronic control unit of the chassis brake system,this research paper compares the advantages and disadvantages of Every schemes,at last recommend some reference scheme for the selection of chassis brake of different types of HAD System.
