The present invention realizes a technique capable of estimating a ground load in a vehicle with sufficiently high accuracy. A ground load estimation device according to the present invention is configured to estimate a ground load of a vehicle by: acquiring a wheel angular velocity, a steady load, and an inertial load of the vehicle; calculating a first gain using the steady load and the inertial load; estimating a road surface load using the first gain, a prescribed vehicle specification, and a second gain representing a hysteresis characteristic of a tire mounted on the vehicle; and referring to the road surface load.
本发明实现了一种能够以足够高的准确度估计车辆中的接地载荷的技术。根据本发明的接地载荷估计装置被配置为通过以下估计车辆的接地载荷:获取车辆的车轮角速度、定常载荷和惯性载荷;使用定常载荷和惯性载荷计算第一增益;使用第一增益、规定的车辆规格和表示安装在车辆上的轮胎的滞后特性的第二增益来估计路面载荷;以及参考所述路面载荷。
