摘　　要：实现转向系统的控制是实现无人驾驶横向控制的基础。文章介绍了一种低速无人驾驶汽车转向系统的控制方案,提供了上位机与转向系统的交互逻辑和控制策略,以及相应的转向性能指标。基于该设计方案,针对不同测试工况进行了实车试验,并分析了不同工况下转向系统的响应性能。道路测试结果表明,该方案可以实现特定道路工况下低速无人驾驶对转向系统的要求。Steering control is the basis of lateral control for autonomous vehicles.In this paper,a control scheme for the steering system of a low-speed driverless car is introduced,and the interaction logic and control strategy between the host computer and the steering system,as well as the corresponding steering performance indicators are provided.Based on the above design scheme,actual vehicle tests are carried out for different test conditions,and the response performance of the steering system under different conditions is analyzed.Road test results show that the solution can achieve the requirements of the steering system for low-speed unmanned driving under specific road conditions.
