| Abstract(E) | Autonomous Emergency Braking (AEB) is the most common type of automobile active safety technology, which can effectively reduce the occurrence of rear-end collision accidents. This paper built a vehicle Simulink model with the WEY VV6 as the prototype, and carried out simulation verification on the braking performance of the model. Based on the traditional TTC (Time to Collision) model, this paper proposed an improved TTC model. Combined with the needs of vehicle operating conditions, the automatic brake system strategy design was completed. This paper also established a hierarchical control strategy based on vehicle speed. Taking safety and comfort as the evaluation indicators, according to the relevant regulations of the 2018 version of C-NCAP, based on the vehicle Simulink model, this paper carried out simulation verification on the control strategy of the braking system. According to the result of the comparative analysis, the control strategy based on the traditional TTC model and the improved TTC model can both avoid collisions, and their safe parking distance is more than 1m, but the improved TTC model has better comfort. |
