The invention discloses a vehicle weight acquisition method and device, electronic equipment and a vehicle, and the method comprises the steps: obtaining the road slope information of a road in front of a vehicle, and obtaining the acceleration of an engine of the vehicle; according to the road gradient information, the vehicle weight component of the vehicle in the front road gradient direction is obtained through calculation; calculating a driving shaft wheel end resultant force of the vehicle according to the vehicle weight component; and dividing the resultant force of the wheel ends of the driving shaft by the acceleration of the engine to obtain the weight of the vehicle. Therefore, according to the vehicle weight obtaining method, the road slope information of the road in front of the vehicle is obtained in real time in the driving process of the vehicle, the vehicle weight component of the vehicle in the slope direction of the road in front of the vehicle is considered into the driving shaft wheel end resultant force of the vehicle, and the vehicle weight of the vehicle can be calculated more accurately.
本发明公开了一种车重获取方法、装置以及电子设备、车辆,该方法包括:获取自车前方道路的道路坡度信息,并获取自车的发动机加速度;根据道路坡度信息,计算得到自车沿前方道路坡度方向的车重分量;根据车重分量计算得到自车的驱动轴轮端合力;将驱动轴轮端合力除以发动机加速度,得到自车的车重。由此,该车重获取方法,在自车行驶过程中,实时获取自车前方道路的道路坡度信息,并将自车沿前方道路坡度方向的车重分量考虑到自车的驱动轴轮端合力中,能够更加精准地计算出自车的车重。
