The invention relates to a whole vehicle mass estimation method and device, electronic equipment and a storage medium, and relates to the technical field of commercial vehicle mass estimation.The method comprises the following steps that in the driving process of a target vehicle, a first target moment and a second target moment are obtained; based on the angular velocities of the transmitter crankshaft of the target vehicle at the two target moments, an acceleration difference value between the first target moment and the second target moment of the target vehicle is obtained; based on the torque difference value of the engine at the first target moment and the second target moment, the traction force difference value of the two target moments is obtained; and obtaining the mass of the target vehicle based on the acceleration difference value and the traction force difference value. The mass of the target vehicle can be estimated only through the angular velocity of the engine crankshaft and the engine torque of the target vehicle, and the angular velocity of the engine crankshaft and the engine torque of the engine can be measured in real time, so that the method is less dependent on parameters, needing to be measured in real time, of the vehicle; and the mass of the vehicle is accurately estimated in real time.
本申请涉及一种整车质量估算方法、装置、电子设备以及存储介质,涉及商用车质量估算技术领域,该方法包括以下步骤:在目标车辆的行驶过程中,获取第一目标时刻与第二目标时刻;基于在两目标时刻的目标车辆的发送机曲轴的角速度,获取目标车辆在第一目标时刻与第二目标时刻之间加速度差值;基于第一目标时刻与第二目标时刻的发动发动机扭矩差值,获取两目标时刻的牵引力差值;基于加速度差值以及牵引力差值,获取目标车辆的质量。本申请仅需通过目标车辆的发动机曲轴的角速度和发动机扭矩就可以完成对目标车辆质量的估算,且发动机曲轴的角速度以及发动机的发动机扭矩是可以通过实时测量的,从而较少依赖车辆需实时测量的参数,对车辆的质量进行实时精确地估算。
