摘要:

采用自动紧急制动 (AEB)可以辅助驾驶员避免纵向碰撞。该文对比了5 种AEB 算法对避免纵向碰撞仿真验证制动效果。以自动制动结束时的己车与前车的距离来判断制动效果的 4 种安全距离 (AS) 算法是:Mazda、Honda、Berkeley、SeungwukMoon ;另一种是以即碰时间 (TTC) 为判断制动效果的 TTC 算法。在 Simulink 中运行的汽车主动安全的仿真平台PreScan上进行仿真验证。结果表明:在不干扰扰驾驶员正常驾驶前提下,这 5 种算法中,以即碰时间的 TTC 算法的纵向避撞性能最优。

Abstract:

 Using autonomous emergency braking (AEB) can assist car-drivers to avoid longitudinal collision. Five AEB algorithms to avoid collision were compared to verify the braking effect. Four kind of safety distance algorithms included Mazda, Honda, Berkeley, and SeungwukMoon, by using the distance between the selfcar and the front-car at the end of automatic braking, to judge the braking effect. The fifth algorithm was TTC algorithm with the time to collision (TTC) judging braking effect. Simulation was performed on the active safety car simulation platform PreScan running in the Simulink software. The results show that the vertical collision avoidance performance of the TTC algorithm is the optimal one among the five under the condition of normal driving without disturbing the driver.
