The embodiment of the invention discloses a vehicle speed display method and device, a vehicle and a computer storage medium. The method comprises the following steps: acquiring a vehicle speed signalvalue at the current moment and a vehicle speed signal value at the previous moment; obtaining the vehicle speed value at the current moment through the formula VN = k1 * (Vn-Vn-1) + Vn, wherein VN is the vehicle speed value at the current moment, Vn is the vehicle speed signal value at the current moment, Vn-1 is the vehicle speed signal value at the last moment, k1 is a positive number larger than 0 and smaller than 1, and n is a natural number larger than or equal to 2; and determining an actual vehicle speed value at the current moment according to the vehicle speed value at the current moment and the vehicle speed display value at the current moment, and displaying the actual vehicle speed value. According to the scheme, the difference value between the vehicle speed signal value atthe current moment and the vehicle speed signal value at the previous moment is reduced to be k1 which is larger than 0 and smaller than 1, shaking or jumping of the vehicle speed signal values is effectively reduced, fluctuation of numbers or pointers is reduced during vehicle speed display, and the impression of a user is improved.
本发明实施例公开了一种车速显示方法、装置、车辆及计算机存储介质。该方法包括:获取当前时刻的车速信号值和上一时刻的车速信号值;通过公式VN=k1*(Vn‑Vn‑1)+Vn得到当前时刻的车速值,其中,VN为当前时刻的车速值,Vn为当前时刻的车速信号值,Vn‑1为上一时刻的车速信号值,k1为大于0小于1的正数,n为大于等于2的自然数;根据所述当前时刻的车速值和当前时刻的车速显示值,确定当前时刻的实际车速值并显示所述实际车速值。上述方案将当前时刻的车速信号值与上一时刻的车速信号值的差值减小为原来的k1,k1为大于0小于1,有效的减小了车速信号值的抖动或跳变,在进行车速显示时,减小了数字或指针的波动,改善了用户的观感。
