As one of the effective means of vehicle collision avoidance, the Automatic Emergency Braking (AEB) system has become the research focus for heavy commercial vehicles in China recently. However, the existing AEB system control algorithm does not consider the influence of road conditions and cannot meet the need of emergency braking for the dangerous goods transportation vehicle. Therefore, this study proposes a vehicle automatic emergency braking control strategy based on real-time perception of road pavement attachment. Firstly, the real-time estimation method of road adhesion coefficient based on vehicle 3D LiDAR is put up. Then, an automatic emergency braking strategy considering road pavement attachment for the dangerous goods transportation vehicle is established. Finally, the simulation and real vehicle tests verification under different dangerous conditions are carried out for this emergency strategy. The results show that under different dangerous conditions and road pavement attachment, the dangerous goods transportation vehicle which installed the proposed independent automatic emergency braking strategy can provide the best braking timing and braking strength. This research will provide theoretical support for practical application of the AEB system in the dangerous goods conveyance realm. It will greatly improve the safety of highway transportation.
