The invention relates to the technical field of automobile electronic control systems and data processing, in particular to a vehicle-mounted instrument vehicle speed data processing method. The method comprises the steps that the actual vehicle speed corresponding to a target vehicle is monitored in real time; smoothing the current actual vehicle speed of the target vehicle according to a low-pass filter to obtain the current instrument speed; whether the target difference value between the actual vehicle speed and the current instrument speed is larger than a preset threshold value or not is judged, and if yes, the smoothing coefficient of a low-pass filter is dynamically adjusted according to the target difference value; performing dynamic smoothing processing on the current instrument speed according to the adjusted smoothing coefficient to obtain a dynamic smoothing speed; and adjusting the current instrument speed to a dynamic smooth speed. By means of the technical scheme, the vehicle speed data processing method of the vehicle-mounted instrument can accurately reflect the real acceleration or deceleration performance of the vehicle, and provides more comfortable visual experience for a driver while keeping the authenticity of the data.

    本申请涉及汽车电子控制系统与数据处理技术领域,具体涉及一种车载仪表车速数据处理方法。该方法包括:通过实时监测目标车辆所对应的实际车速;根据低通滤波器对目标车辆当前的实际车速进行平滑处理,得到当前仪表速度;判断实际车速与当前仪表速度之间的目标差值是否大于预设阈值,若是,则根据目标差值动态调整低通滤波器的平滑系数;根据调整后的平滑系数对当前仪表速度进行动态平滑处理,得到动态平滑速度;将当前仪表速度调整为动态平滑速度。通过以上技术方案,本申请提出的一种车载仪表车速数据处理方法可以准确反映车辆的真实加速或减速性能,在保留数据真实性的同时,给驾驶员提供了更加舒适的视觉体验。
