【摘要】：针对频繁发生的驾驶员误将加速踏板当作制动踏板而引起严重交通事故的现象,以加速踏板力、加速踏板的加速度、汽车与前方障碍物的距离及方向盘手握力作为联合判别参数,建立了驾驶员误踩油门判别逻辑规则,并以STC89C52单片机为核心设计出一种基于联合判别参数的防误踩油门制动控制系统,并对该系统进行了实车制动控制性能试验。试验结果表明,驾驶员在车速为20 km/h、40 km/h、60 km/h时误踩油门时,该系统紧急制动,并得到从误踩油门到汽车完全停止后的距离分别为3.66 m、10.79 m、21.10 m,比理论制动停车距离略小。可知该系统能够较精确地判断驾驶员误踩油门行为并能高效地进行制动,所设计的防误踩油门制动控制系统是可靠的,能够显著提高汽车的主动安全性。
[Abstract]:In order to accelerate the pedal force and accelerate the acceleration of the pedal, the driver mistakenly takes the accelerator pedal as the brake pedal and causes the serious traffic accident in order to accelerate the pedal force and the acceleration of the pedal.The distance between the vehicle and the obstacle in front and the grip force of the steering wheel hand are used as the joint discriminant parameters to establish the discriminant logic rule of the driver's wrong stepping on the throttle.Based on the STC89C52 single chip microcomputer, a control system of anti-misstepping throttle brake based on joint discriminant parameters is designed, and the real vehicle brake control performance test is carried out.The test results show that when the driver steps on the throttle at the speed of 20 km / h 40 km / h or 60 km/h, the system can brake urgently, and the distance from the wrong pedal to the complete stop of the vehicle is 3.66 m- 10.79 m-1 / 21.10 m, which is slightly smaller than that of the theoretical braking stop.It is known that the system can accurately judge the driver's misstepping on the throttle and can efficiently brake. The designed anti-misstepping throttle brake control system is reliable and can significantly improve the active safety of the vehicle.
