基于有限状态自动机的绿通车辆驾驶室避让控制

Control method for vehicle cab avoidance in free toll lane of highway based on finite state machine

在高速公路绿通车道检测过程中,为了避免射线对驾驶员身体造成伤害,需要对车辆的驾驶室进行避让。本文提出了一种基于有限状态自动机的绿通车辆驾驶室避让控制方法。首先在对车辆通过绿通车道时的状态进行分析的基础上,建立了车辆驾驶室避让的自动状态机模型;然后根据该模型编制了相应的控制程序,对该状态机模型进行了仿真验证和考核;最后对绿通车辆大量的实测数据进行分析。结果表明:基于有限状态自动机的驾驶室避让控制方法能够准确有效地实现驾驶室避让控制,有效地剔除非车辆通行所导致的误动作。

In order to avoid the radiation injury to the drivers in the detection process of the free toll lane in highway, the vehicle cab should be stepped aside; such vehicle is called green-vehicle. A new avoidance control method of green-vehicle cab is proposed using the finite state machine. First, on the basis of the mechanism of vehicle cab avoidance, the finite state machine model of green-vehicle cab avoidance is established. The program is developed based on the model for simulation and evaluation. Simulations are carried out to access and validate the finite state machine model. A large amount of real data measured from experiment is analyzed. The results prove that the control method can accurately and effectively achieve cab avoidance, and eliminate the misoperation caused by non green- vehicles.
