自动紧急制动系统控制策略仿真验证

Simulation Verification of Control Strategy of Automatic Emergency Braking System

为了在危险情况时辅助驾驶员实现纵向避撞或减小碰撞造成的伤害,文章提出了一种考虑实际制动过程与驾驶员制动行为的分级制动控制策略。通过试验得到相关参数,根据新车评价标准的AEB测试工况与评价指标,搭建测试场景并评价新车AEB功能。仿真结果表明,AEB控制策略在所有工况下都能达到新车评价规程中AEB功能的标准。提出的分级制动控制策略具有一定的参考价值。仿真模型可以方便地更改参数以适用于不同车辆,可作为新车评价AEB功能的仿真工具,减小试验成本,具有实用价值。

In order to assist the driver in longitudinal collision avoidance or reduce the damage caused by the collision in dangerous situations, a hierarchical braking control strategy that considers the actual braking process and the braking behavior of the driver is proposed. Relevant parameters are obtained through experiments. According to the AEB test conditions and evaluation indicators of the new car evaluation standard, the test scene is built and the new car AEB function is evaluated. The simulation results show that the AEB control strategy can reach the standard of AEB function in the new car evaluation procedure under all working conditions. The proposed hierarchical braking control strategy has certain reference value. The simulation model can easily change the parameters to be suitable for different vehicles. It can be used as a simulation tool for evaluating the AEB function of a new car, reduces test costs and has practical value.
