摘要：
When receiving emergent signals, active pre-tensioning safety belt can effectively eliminate belt slack before collision, thereby reducing the injury and the risk of secondary impacts of occupant in a frontal collision. In this paper, firstly on the base of modeling and simulation, the function of reducing occupant injury of active pre-tensioning safety belt is verified. Then the parameters of control system are determined, and hence the design of software system algorithm is completed, realizing the preferential execution of the signal with higher priority and ensuring the parallel execution of signal scanning and motor running. Finally, a static bench test is conducted,verifying the functional reliability of control system. The results show that intelligent control system can effectively carry out CAN communication, accurately execute the instruction of belt pre-tensioning, effectively supporting the function execution of active pre-tensioning safety belt. © 2016, Society of Automotive Engineers of China.
