车辆行驶记录仪已陆续在许多国家和地区大量使用。该行驶记录仪基于单片机控制,采用flash存储技术,通过霍尔传感器和加速度传感器,记录车辆的行驶状态,可以对驾驶员驾驶行为进行记录,有助于监督驾驶员合法行驶,减少交通事故,并且该记录仪能够通过汽车发生碰撞前后的状态数据,计算出汽车在碰撞过程中的运动轨迹,有助于对交通事故的原因和责任的鉴定。
Vehicle drive recorder has gradually been widely used in many countries and regions. The tachograph is based on single-chip microcomputer control, using flash memory technology, through the Hall sensor and acceleration sensor, record the driving status of the vehicle, can record the driver’s driving behavior, help monitor the driver’s legal driving, reduce traffic accidents, and The recorder can calculate the car’s motion trajectory during the collision process through the status data before and after the collision of the car and contribute to the identification of the cause and responsibility of the traffic accident.
