Abstract: 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.
