The invention discloses a vehicle speed display method, a vehicle speed display system and a vehicle, and the vehicle speed display method comprises the steps: obtaining a cruise vehicle speed value; obtaining an actual vehicle speed value, and obtaining a vehicle speed calculation value displayed by an instrument according to the actual vehicle speed value; determining that a jump value exists between the instrument display vehicle speed calculation value and the cruise vehicle speed value; negative feedback operation is carried out according to the instrument display vehicle speed calculation value and the cruising vehicle speed value until no jump value exists between the instrument display vehicle speed calculation value and the cruising vehicle speed value, and the final instrument display vehicle speed calculation value serves as a target instrument display vehicle speed calculation value; and displaying the vehicle speed according to the vehicle speed calculation value displayed by the target instrument. According to the method, when the vehicle speed value displayed by the combination instrument has the jump value, the vehicle speed calculation value displayed by the instrument is recalculated in a negative feedback operation mode, so that the vehicle speed value displayed by the instrument is kept consistent with the cruising vehicle speed value, and the problem that the vehicle speed value displayed by the instrument has the jump value is avoided.

    本发明公开了一种车速显示方法、车速显示系统和车辆,所述车速显示方法,包括:获取巡航车速值;获取实际车速值,并根据所述实际车速值获得仪表显示车速计算值;确定所述仪表显示车速计算值与所述巡航车速值之间存在跳值;根据所述仪表显示车速计算值和所述巡航车速值进行负反馈运算,直至所述仪表显示车速计算值与所述巡航车速值之间不存在跳值,将最终的仪表显示车速计算值作为目标仪表显示车速计算值;根据所述目标仪表显示车速计算值显示车速。该方法在组合仪表显示的车速值存在跳值时,通过负反馈运算的形式对仪表显示车速计算值进行重新计算,以使仪表显示车速值与巡航车速值保持一致,从而避免仪表上显示的车速值存在跳值的问题。
