The invention relates to a vehicle and a height-limiting anti-collision control method thereof, wherein the method comprises the steps: obtaining an image of a height-limiting rod in front of the vehicle and the gradient of a road surface where the vehicle is located, and determining the vertical passing size of the height-limiting rod and the road surface according to the image of the height-limiting rod; obtaining the vertical distance between the height-limiting rod and the road surface according to the vertical traffic size and the slope of the road surface; and if the vehicle body height is greater than the vertical distance, outputting alarm information and/or controlling the vehicle to slow down. At the moment, the road surface where the height-limiting rod is located has a slope, when the vehicle goes uphill or downhill, the allowed actual traffic size is not the vertical traffic size any more, but the vertical distance between the height-limiting rod and the road surface, and thus the actual traffic size of the slope road surface, namely the vertical distance between the height-limiting rod and the road surface, can be obtained according to the slope and the vertical traffic size. The vehicle top scraping or collision caused by the fact that the height between the height-limiting rod and the horizontal plane serves as the actual passing size is avoided, the safety and reliability when the vehicle passes through a traffic control obstacle are improved, and unnecessary property loss is reduced.
本发明涉及一种车辆及其限高防碰撞控制方法,通过获取车辆前方限高杆的图像和车辆所在路面的坡度,根据限高杆的图像确定限高杆与路面的竖直通行尺寸;再根据竖直通行尺寸和路面的坡度得到限高杆与路面的垂直距离;若车身高度大于垂直距离,则输出报警信息和/或控制车辆减速。此时限高杆所在处的路面带有坡度,如上坡或者下坡时,此处所允许的实际通行尺寸不再是竖直通行尺寸,而是限高杆与路面的垂直距离,因此,根据坡度和竖直通行尺寸即可得到这种坡度路面的实际通行尺寸即限高杆与路面的垂直距离,避免了限高杆与水平面之间的高度作为实际通行尺寸造成车辆刮顶或者碰撞,提高了车辆过限行障碍物时的安全性和可靠性,减少了不必要的财产损失。
