摘要

提出了一种基于驾驶员制动加速度分析的分层制动控制策略。首先利用驾驶模拟器采集驾驶员制动时的车辆状态数据。然后通过分析车辆在制动时的加速度，确定驾驶员在避碰时的期望加速度，并根据该期望加速度值划分TTC阈值。基于二阶碰撞时间模型，设计了两级预警和两级制动避碰策略。最后，在Simulink/ Carsim中构建了碰撞预警系统的整体仿真模型。联合仿真试验结果表明，该系统的分层制动预警策略能够有效地避免碰撞。

Longitudinal collision warning system based on driver braking characteristics

A hierarchical braking control strategy based on driver braking acceleration analysis is proposed in this paper. Firstly the vehicle state data of the driver during braking collected by driving simulator. Then by analyzing the acceleration of the vehicle during braking, the driver's desired acceleration during collision avoidance is determined, and the TTC threshold is divided according to this desired acceleration value. The two-level warning and two-level braking collision avoidance strategies are designed based on the second-order collision time model. Finally, the overall simulation model of the collision warning system is constructed in Simulink/ Carsim. The co-simulation test results demonstrate that the hierarchical braking and warning strategy of this system can effectively avoid crash.
