The invention discloses a sensorless vehicle weight estimation method and device and a storage medium. The method comprises the following steps: acquiring real-time state information of a to-be-estimated vehicle, and determining first average state information of a first time period and second average state information of a second time period based on the real-time state information; determining a first estimated vehicle weight based on the real-time state information; determining a second estimated vehicle weight based on the first average state information and the second average state information; determining whether an absolute value of a difference value between the first estimated vehicle weight and the second estimated vehicle weight is smaller than a preset difference value or not; and determining the estimated vehicle weight to be updated of the vehicle to be estimated based on the first estimated vehicle weight and the second estimated vehicle weight under the condition that the difference value is smaller than the preset difference value. According to the method, the sensor-free accurate estimation of the vehicle weight and the recognition of the road condition are realized.

    本申请公开了一种无传感器车重估算方法、设备及存储介质。方法包括:获取待估算车辆的实时状态信息,并基于实时状态信息,确定第一时间区段的第一平均状态信息与第二时间区段的第二平均状态信息;基于实时状态信息,确定第一估算车重;基于第一平均状态信息与第二平均状态信息,确定第二估算车重;确定第一估算车重与第二估算车重的差值的绝对值是否小于预设差值;在确定小于预设差值的情况下,基于第一估算车重与第二估算车重,确定待估算车辆的待更新估算车重。本申请通过上述方法实现了无传感器精确估算汽车车重及识别道路路况。
