The invention discloses a new vehicle recording method capable of saving hard disk storage space under an intelligent driving background, which comprises a sensor, a CPU (Central Processing Unit), an interrupt controller, a control logic, a timer, an interface, an ROM (Read Only Memory), an RAM (Random Access Memory) and a special function register, the short-distance large-angle millimeter-wave angle radar, the laser radar, the long-distance millimeter-wave radar, the short-distance large-angle panoramic camera and the long-distance millimeter-wave radar are connected with the CPU through interfaces. According to the new vehicle recording method capable of saving the hard disk storage space under the intelligent driving background, the sensor is adopted for detecting vehicle information data, collection and detection of the vehicle data are facilitated, the data is periodically transmitted into the RAM through the CPU, coverage recording is conducted through the RAM, the hard disk storage space is saved, the service life is prolonged, and when a special event occurs, the ROM is used for recording, so that the data is prevented from being covered, and the data storage is ensured, thereby achieving the effects of saving the hard disk storage space and prolonging the service life.
本发明公开了智能驾驶背景下一种节省硬盘存储空间的新车记录方法,包括传感器、CPU、中断控制、控制逻辑、定时器、接口、ROM、RAM和特殊功能寄存器,近距离大角度毫米波角雷达、激光雷达、远距离毫米波雷达、近距离大角度全景摄像头、远距离毫米波雷达均通过接口连接CPU;本发明智能驾驶背景下一种节省硬盘存储空间的新车记录方法采用传感器进行检测车辆信息数据,方便车辆数据的收集检测,通过CPU进行周期性的将数据传输至RAM中,通过RAM进行覆盖记录,节省硬盘存储空间,延长使用寿命,而当出现特殊事件时,再通过ROM进行记录,防止数据被覆盖,保证数据的存储,从而达到节省硬盘存储空间,延长使用寿命的效果。
