The invention discloses a cargo weight estimation device and method. A cargo weight estimation device includes: a TPMS sensor that measures an air pressure of a tire; and a controller calculating a first ground contact area of the tire according to a first air pressure of the tire before loading the cargo measured by the TPMS sensor, and calculating a second ground contact area of the tire according to a second air pressure of the tire after loading the cargo measured by the TPMS sensor, and estimating the weight of the cargo loaded in the vehicle based on the first ground contact area and the second ground contact area.

    本发明公开一种货物重量估计装置和方法。一种货物重量估计装置包括:TPMS传感器,测量轮胎的气压;以及控制器,根据TPMS传感器测量的在装载货物之前的轮胎的第一气压计算轮胎的第一接地面积,根据TPMS传感器测量的在装载货物之后的轮胎的第二气压计算轮胎的第二接地面积,并基于第一接地面积和第二接地面积估计装载在车辆中的货物的重量。
