Autonomous Emergency Braking Strategy for Dangerous Goods Transportation Vehicle Based on Real-Time Sensing of Road Pavement Attachment

As an 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 algorithms do 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 forward. Then, an automatic emergency braking strategy considering road pavement attachment is established. Finally, a test under different dangerous conditions is carried out. The results show that the dangerous goods transportation vehicle which installed the proposed strategy can provide the best braking timing and braking strength. This research will greatly improve the safety of highway transportation.
