The invention discloses a road slope determination method and device, and belongs to the technical field of vehicles. In the process that the vehicle runs on the target road, according to the running speed of the vehicle at the ith sampling moment and the running speed of the vehicle at the (i + 1) th sampling moment, the calculated acceleration of the vehicle at the (i + 1) th sampling moment is determined. And determining an acceleration difference value corresponding to the (i + 1) th sampling moment according to the sampling acceleration of the vehicle at the (i + 1) th sampling moment and the calculated acceleration of the vehicle at the (i + 1) th sampling moment. And determining the road gradient of the target road according to the acceleration difference values corresponding to the plurality of sampling moments. The road gradient of the target road can be determined according to the driving speeds and the sampling accelerations of the vehicle at the plurality of sampling moments, so that parameters needing to be acquired in the process of determining the road gradient of the target road are few, and the process of determining the road gradient can be simplified.

    本申请公开一种道路坡度的确定方法和装置,属于车辆技术领域。在车辆在目标道路上行驶的过程中,根据该车辆在第i个采样时刻的行驶速度和该车辆在第i+1个采样时刻的行驶速度,确定该车辆在该第i+1个采样时刻的计算加速度。根据该车辆在该第i+1个采样时刻的采样加速度和该车辆在该第i+1个采样时刻的计算加速度,确定该第i+1个采样时刻对应的加速度差值。根据多个采样时刻对应的加速度差值确定目标道路的道路坡度。由于根据车辆在多个采样时刻的行驶速度和采样加速度就可以确定目标道路的道路坡度,因此,确定目标道路的道路坡度的过程中需要获取的参数较少,可以简化确定道路坡度的过程。
