A method for determining vehicle pitch includes a first operating state defined by a vehicle above a speed threshold, during which absolute vehicle pitch is determined using a plurality of inputs. The vehicle pitch may be calculated by integrating the longitudinal acceleration measurements to estimate the distance average global attitude of the longitudinal acceleration measurements while taking into account variations in vehicle speed and average gravitational acceleration due to gradient. The method also includes a second operating state defined by the vehicle being below the speed threshold, during which the relative vehicle pitch is determined using the plurality of inputs.
一种用于确定车辆俯仰的方法包括由车辆高于速度阈值定义的第一操作状态,在此期间使用多个输入来确定绝对车辆俯仰。车辆俯仰可以通过以下方式来计算:积分纵向加速度测量,以估计纵向加速度测量的距离平均全局姿态,同时考虑车辆速度的变化和由于坡度引起的平均重力加速度。该方法还包括由车辆低于速度阈值定义的第二操作状态,在此期间,使用多个输入来确定相对车辆俯仰。
