The invention provides a vehicle speed prediction method and device, a computer readable storage medium and a vehicle. The method comprises the following steps: performing linear fitting on a target vehicle speed value and a target serial number at each target moment in a target array to obtain a vehicle speed prediction formula; calculating a predicted vehicle speed value of the target vehicle at the current moment based on a vehicle speed prediction formula and the target serial number of the target vehicle at the current moment in the target array; under the condition that the difference value between the predicted vehicle speed value at the current moment and the actual vehicle speed value is larger than or equal to a preset threshold value, the predicted vehicle speed value is determined as the current vehicle speed value at the current moment, and under the condition that the difference value between the predicted vehicle speed value at the current moment and the actual vehicle speed value is smaller than the preset threshold value, the predicted vehicle speed value is determined as the current vehicle speed value. And the current vehicle speed value at the current moment is determined at least based on the target vehicle speed value at the previous target moment adjacent to the current moment, so that the problems of relatively large historical data volume and relatively large calculated amount required by vehicle speed prediction in the prior art are solved.

    本申请提供了一种车速预测方法、预测装置、计算机可读存储介质与车辆。该方法包括:对目标数组中的各目标时刻的目标车速值以及目标序号进行线性拟合,得到车速预测公式;基于车速预测公式和当前时刻在目标数组中的目标序号,计算目标车辆在当前时刻的预测车速值;在当前时刻的预测车速值与实际车速值的差值大于或者等于预定阈值的情况下,将预测车速值确定为当前时刻的当前车速值,在当前时刻的预测车速值与实际车速值的差值小于预定阈值的情况下,至少基于与当前时刻相邻的上一个目标时刻的目标车速值,确定当前时刻的当前车速值,从而解决了现有技术中对车速的预测所需的历史数据量较大以及计算量较大的问题。
