一种客车驾驶防干扰装置设计

Design of Anti-interference Device for Bus Driving

为保障客车驾驶员的良好驾驶环境,防止乘客拉扯方向盘造成行车安全事故,设计了一种摩擦式客车驾驶防干扰装置。本装置采用高速摄像头与LM1881图像处理电路识别干扰源,采用角速度传感器测量方向盘转动角速度。中央处理模块进行数值处理后,将其与数据库中安全阈值进行对比,决定是否启动摩擦锁紧装置与联动制动系统,从而协助驾驶员控制方向并实现汽车减速,同时开启危险警示灯,保障客车行车安全。

In order to ensure a good driving environment for bus drivers and prevent passengers from pulling the steering wheel,a friction type anti-interference device for bus driving was designed.The device uses high-speed camera and LM1881 image processing circuit to identify the interference source,and uses the angular speed sensor to measure the steering wheel rotation angular speed.After numerical processing,the central processing module compares it with the safety threshold in the database to decide whether to start the friction locking device and the linkage braking system,so as to assist the driver to control the direction and realize the deceleration of the car,and at the same time,turn on the hazard warning light to ensure the driving safety of the bus.
