The invention relates to a vehicle mass estimation method and device, electronic equipment and a storage medium. The method comprises the steps: when the vehicle is in a sliding state, monitoring the pedal opening degree of the vehicle; when it is monitored that the pedal opening degree meets the preset triggering condition, taking the current moment as the first moment, and obtaining the first acceleration of the vehicle at the first moment; controlling the motor to output the torque at the constant target torque; determining a second moment according to the first moment and a first preset duration, and obtaining an actual output torque of the motor at the second moment; when the actual output torque is the same as the target torque, obtaining a second acceleration of the vehicle at a second moment; and according to the target torque, the first acceleration and the second acceleration, estimating the whole vehicle mass of the vehicle. By adopting the method, the vehicle mass estimation difficulty can be reduced.

    本申请涉及一种整车质量估算方法、装置、电子设备和存储介质。所述方法包括:当车辆处于滑行状态时,监测车辆的踏板开度;当监测到踏板开度满足预设触发条件时,将当前时刻作为第一时刻,获取车辆在第一时刻的第一加速度;以恒定的目标扭矩控制电机进行扭矩输出;根据第一时刻和第一预设时长,确定第二时刻,获取电机在第二时刻的实际输出扭矩;当实际输出扭矩与目标扭矩相同时,获取车辆在第二时刻的第二加速度;根据目标扭矩、第一加速度和第二加速度,对车辆的整车质量进行估算。采用本方法能够降低整车质量估算难度。
