Design of Active Safety Warning System for Hazardous Chemical Transportation Vehicle

As the hazardous chemical transportation traffic accident is getting more and more serious, this paper designs a kind of active safety warning system for hazardous chemical transportation vehicle. The content of this paper mainly includes the composition and principle, establishment of theoretical model of safety distance, design of avoidance control strategy and algorithm and so on. This paper firstly introduces the composition and function of the active safety warning system for hazardous chemical transportation vehicle, and claries its working principle. And then establishes a safety distance model according to the theory of vehicle dynamics, and another four models of key vehicle distance which include safety critical, target vehicle, dangerous critical and limit critical. According to the different dynamic models, the paper designs four control strategies including safety control, alarm control, deceleration control and brake control and the algorithm. In this paper, the active safety warning system for hazardous chemical transportation vehicle can help the driver avoid traffic accident in the course of transportation, detect the safety state of the tank, improve the safety performance of the vehicle at the greatest degree and realize the intelligent monitoring of the hazardous chemical transportation vehicle.
