The invention relates to a vehicle mass estimation method and device, a medium, equipment and a vehicle. The method comprises the following steps: acquiring driving state data of the vehicle; the driving state data comprises a current gear command, a current road slope, a current acceleration, a current vehicle speed and a current driving torque of a motor; judging whether a mass estimation triggering condition is met or not based on the driving state data; continuing to obtain the road rolling resistance when judging that the mass estimation triggering condition is met; an estimated mass of the vehicle is determined based on the current vehicle speed, the current acceleration, the current road gradient, the road rolling resistance, and the current drive torque. Therefore, additional sensors are not needed, the space of a vehicle is not occupied, the input cost of the vehicle is not increased, and popularization and application are facilitated; meanwhile, mass estimation can be carried out in combination with the actual conditions of the vehicle and the road, the accuracy of mass estimation is high, and timely following of the vehicle speed is facilitated.
本公开涉及车辆的质量估算方法、装置、介质、设备及车辆，该方法包括：获取车辆的行驶状态数据；行驶状态数据包括当前档位命令、当前道路坡度、当前加速度、当前车速以及电机的当前驱动扭矩；基于行驶状态数据，判断是否满足质量估算触发条件；判定满足质量估算触发条件时，继续获取道路滚动阻力；基于当前车速、当前加速度、当前道路坡度、道路滚动阻力以及当前驱动扭矩，确定车辆的估算质量。由此，可无需增加额外的传感器，从而无需占用车辆的空间，不会增大车辆的投入成本，便于推广使用；同时，能够结合车辆和道路的实际情况进行质量估算，质量估算的准确性较高，有利于实现车速及时跟随。
