A method for vehicle mass estimation includes: setting a vehicle mass value as an initial value and setting a driving resistance value as an initial value; receiving at least a longitudinal acceleration value, a drive/brake torque on each axle/wheel, and a wheel angular velocity value; and estimating a drive resistance value based on the vehicle mass value and the wheel angular velocity value. The method further includes setting the drive resistance value to an estimated drive resistance value and determining a fuel level value of the associated vehicle and a seat occupancy value of the at least one seat. The method further includes estimating a vehicle load value using the fuel level value and the seat occupancy value, and setting at least one of a vehicle center of gravity value and a vehicle moment of inertia value based on the vehicle load value.
一种用于车辆质量估计的方法,包括:将车辆质量值设定为初始值,并将驱动阻力值设定为初始值;至少接收纵向加速度值、每个轴/车轮上的驱动/制动扭矩,以及车轮角速度值;以及,基于车辆质量值和车轮角速度值对驱动阻力值进行估计。该方法还包括将驱动阻力值设定为估计驱动阻力值,并确定相关车辆的燃油油位值和至少一个座椅的座椅占用值。该方法还包括使用燃油油位值和座椅占用值对车辆负载值进行估计,并基于车辆负载值来设定车辆重心值和车辆惯性矩值中的至少一个。
