The invention discloses a deceleration strip detection method and device. The method comprises the steps that the longitudinal acceleration and the vehicle speed of a vehicle are obtained through a CAN bus and/or a sensor of the vehicle; according to the longitudinal acceleration and the vehicle speed, a slope angle on a driving road where the vehicle is located is obtained; and detecting the speed bump on the driving road through the slope angle. As the vehicle runs through the deceleration strip, the vehicle can be regarded as going uphill and then going downhill in a short time and finally runs on the road with the original gradient, and therefore, the deceleration strip can be detected according to the slope angle. According to the deceleration strip detection method provided by the invention, the deceleration strip can be detected only by using two kinds of data of the longitudinal acceleration and the vehicle speed of the vehicle, and the method is simpler and quicker.
本申请公开了一种减速带检测的方法及装置,方法包括:通过车辆的CAN总线和/或传感器获取车辆的纵向加速度和车速;根据纵向加速度和车速,获得车辆所在的行驶道路上的坡角;通过坡角检测行驶道路上的减速带。由于车辆行驶过减速带,可以视为车辆在短时间内先上坡再下坡,最后行驶在原有坡度的道路上,因此,可以根据坡角检测减速带。本申请提供的减速带检测的方法,仅使用了车辆的纵向加速度和车速两种数据即可检测减速带,更加简单、快捷。
