The invention relates to a vehicle speed verification method and device, equipment and a storage medium. The method comprises the following steps: acquiring a first vehicle speed according to the rotating speed of an output shaft of a gearbox; acquiring a second vehicle speed according to the wheel relative speed; if the difference value between the first vehicle speed and the second vehicle speed is not greater than the vehicle speed difference threshold value, or the difference value between the first vehicle speed and the second vehicle speed is greater than the vehicle speed difference threshold value and the duration is less than the time threshold value, displaying the first vehicle speed; and if the difference value between the first vehicle speed and the second vehicle speed is larger than the vehicle speed difference threshold value and the duration time is larger than the first time threshold value, displaying the first vehicle speed, and displaying that the first vehicle speed is not credible. By comparing the first vehicle speed with the second vehicle speed, after the deviation occurs, a driver can realize the situation that the vehicle has problems at present and can perform adjustment as soon as possible, the first time threshold value is set as the transition time, the situation that the first vehicle speed is instantaneously changed due to the instantaneous error occurring in the measurement process and misinformation is performed is filtered out, and finally, the compliance and the safety of the driver in the driving process are improved.
本申请涉及一种车速校验方法及装置、设备和存储介质,其包括以下步骤:根据变速箱输出轴转速得到第一车速;根据车轮相对速度得到第二车速;若第一车速与第二车速的差值不大于车速差阈值,或者,第一车速与第二车速的差值大于车速差阈值,持续时间小于时间阈值,显示第一车速;若第一车速与第二车速的差值大于车速差阈值,且持续时间大于第一时间阈值,显示第一车速,并显示第一车速不可信。通过比对第一车速与第二车速在出现偏差后使驾驶员意识到目前车辆已出现问题的情况并能够及早进行调整,设置第一时间阈值作为过渡时间,滤除测量时中出现的瞬时误差导致第一车速瞬时变动而进行误报的情况,最终提高驾驶员在行驶过程中的合规性与安全性。
