基于模糊推理的油门防误踩系统控制研究

Research on the Control System of Preventing False Stepping the Accelerating Pedal Based on the Fuzzy Theory

针对目前驾驶员由于紧张等原因造成误将油门当做制动踏板踩下造成交通事故的问题,分析了现有油门防误踩系统的特点及不足,提出一种新的汽车油门防误踩系统控制方案。该系统利用车距信号、车速信号及油门踏板加速度信号,通过模糊推理算法,智能、准确的判定驾驶员对油门踏板的操作是否为误操作。采用该算法后,保证了误踩油门的辨识度,从而可实现油门防误踩的执行机构的精准启动,可有效防止驾驶员误踩油门导致的安全事故。

IIn order to solve the problem that the traffic accidents caused by the drivers who use the accelerator as a brake pedal. This paper analyze the current preventing false stepping the accelerating pedal system’s features and shortcomings, and proposes a new control scheme for preventing the driver from falsely stepping the accelerating pedal. The system makes three parameters as inputs, the vehicle distance signal, speed signal and accelerator pedal acceleration signal, determine intelligently and accurately the driver’s operation on the accelerator pedal is correct or not through the fuzzy reasoning algorithm. The system is excellent at the identification of the pedal misapplication, so the actuator of pedal misapplication can be started accurately, and it can prevent the accident effectively caused by the dricers’ pedal misapplication.
