The invention discloses an automobile safety speed limiting device based on cooperative work of a GPS, an Internet of Vehicles and a CANFD bus. The automobile safety speed limiting device comprises a measuring module and a control module, wherein the measuring module measures the speed per hour V and the position P in an automobile driving process and transmits the speed per hour V and the position P to the control module, the control module judges whether the automobile is overspeed according to the speed per hour V and the position P, and when the automobile is overspeed, the control module controls the automobile to adjust the speed limit. According to the invention, the latest Internet of Vehicles technology is adopted, a vehicle-mounted GIS system is replaced by vehicle-mounted 5G, a remote terminal server is accessed through networking, and query of the speed limit of the current road section is achieved; the speed per hour and the position of the automobile can be measured by using a GPS; and according to the output result of a speed comparator, a power control system and a brake control system of an automobile are adjusted and controlled through a CANFD bus, so that the speed per hour of the automobile is reduced to be below the speed limit of the current road section.

    本发明公开了一种基于GPS、车联网及CANFD总线协同工作的汽车安全限速装置,包含测量模块和控制模块两大部分,测量模块测得汽车行驶过程中的时速V和位置P并传送至控制模块,控制模块根据时速V和位置P判断汽车是否超速,汽车超速时,由控制模块控制汽车调整限速。本发明采用最新的车联网技术,使用车载5G替代车载GIS系统,通过联网访问远程终端服务器,实现对当前路段限速的查询;同时,利用GPS可以完成对汽车时速和位置的测量;最后,根据速度比较器的输出结果,通过CANFD总线调节控制汽车的动力控制系统与制动控制系统,使汽车的时速降低到当前路段的限速之下。
