The invention provides a driving early warning method and a driving early warning system. The driving early warning method comprises the following steps: acquiring a trigger event for starting driving early warning work; acquiring detection distances between different positions of the vehicle body detected by a vehicle body radar and surrounding obstacles; determining a to-be-early-warned vehicle body area according to the detection distance, and recording a to-be-output detection distance between the to-be-early-warned vehicle body area and the nearest obstacle; displaying a top view image of the vehicle body on a vehicle display screen, wherein the top view image comprises a panoramic image of the vehicle body and surrounding obstacles and/or an amplified image of a vehicle body area to be pre-warned and surrounding obstacles; calculating a verification distance between the vehicle body area to be pre-warned and the nearest obstacle according to the proportion of the top view image to the entity; and comparing the to-be-output detection distance with the verification distance, and outputting the smaller distance as an early warning distance. According to the scheme, the calibrated distance between the vehicle body and the obstacle can be transmitted to a driver, and the driver is assisted in making more accurate judgment and operation.

    本发明提供了一种行车预警方法以及行车预警系统。行车预警方法包括:获取用于启动行车预警工作的触发事件;获取车身雷达探测得到的车身不同位置与周围障碍物的检测距离;根据检测距离确定出待预警车身区域,并记录待预警车身区域与最近障碍物之间的待输出检测距离;在车辆显示屏显示车身的俯视图像,俯视图像包括车身与周围障碍物的全景图像和/或待预警车身区域与周围障碍物的放大图像;根据俯视图像与实体的比例计算待预警车身区域与最近障碍物之间的校验距离;比较待输出检测距离和校验距离,将较小的一者作为预警距离进行输出。本方案能够向驾驶员传达车身与障碍物之间校准后的距离,辅助驾驶员做出更加准确的判断和操作。
