The invention relates to a method and system for dynamically adjusting output vehicle information frequency and a storage medium, and the method comprises the steps: M1, obtaining the speed data information of a vehicle from a CAN message at a sampling frequency of a fixed period when the vehicle runs on a road, carrying out the timestamp calibration, and obtaining the speed data information of the vehicle with the timestamp calibration; and M2, based on the speed data information of the vehicle with the timestamp calibration, adjusting the output frequency of the vehicle information by adopting a piecewise linear interpolation algorithm of the vehicle speed, and outputting the output frequency data information of the vehicle information. According to the invention, not only can the network bandwidth be effectively saved and the power consumption be effectively reduced, but also the abrupt problem that the vehicle position information of the vehicle jumps on the HMI human-computer interaction interface is solved.

    本发明涉及一种动态调整输出车辆信息频率的方法、系统及存储介质,所述方法包括:M1.车辆行驶在道路上,以固定周期的采样频率从CAN报文中获取车辆的速度数据信息,并进行时间戳标定,得到带有时间戳标定的车辆的速度数据信息;M2.基于所述带有时间戳标定的车辆的速度数据信息,采用车辆速度的分段线性插值算法对车辆信息的输出频率进行调节,输出车辆信息的输出频率数据信息。本发明不仅可以有效的节省网络带宽和降低功耗,而且解决了车辆在HMI人机交互界面上车辆位置信息跳变的突兀。
