The invention provides a vehicle weight estimation method, device and equipment and a medium, and the method comprises the steps: obtaining the first driving data of a vehicle at the current moment; determining a current vehicle weight estimation value based on the first driving data at the current moment; based on the current vehicle weight estimation value, a historical vehicle weight correction value and a preset attenuation coefficient, a current vehicle weight correction value is determined, and the historical vehicle weight correction value is the vehicle weight correction value of the vehicle at the previous moment of the current moment; and repeatedly executing the step of determining the current vehicle weight correction value, and determining that the current vehicle weight correction value is the vehicle weight estimation result of the vehicle under the condition that the current vehicle weight correction value and the historical vehicle weight correction value meet a preset vehicle weight stable change condition. According to the method, the current vehicle weight correction value tending to be stable is determined as the vehicle weight estimation result of the vehicle, so that the accuracy of vehicle weight estimation is improved.

    本发明提供一种车重估算方法、装置、设备及介质,其中,方法包括:获取车辆在当前时刻的第一行驶数据;基于所述当前时刻的第一行驶数据,确定当前车重估算值;基于所述当前车重估算值、历史车重修正值和预设的衰减系数,确定当前车重修正值,所述历史车重修正值为所述车辆在所述当前时刻的上一时刻的车重修正值;重复执行确定所述当前车重修正值的步骤,在所述当前车重修正值与所述历史车重修正值满足预设的车重稳定变化条件的情况下,确定所述当前车重修正值为所述车辆的车重估算结果。本发明通过确定趋于稳定的当前车重修正值为车辆的车重估算结果,有利于提高车重估算的准确度。
