Problems solved by technology

[0002] At present, after the vehicle is installed, the on-board ECU software cannot be updated remotely. Once the update is required, the user must drive the vehicle to a designated location, or a professional must go to the user to update it manually. The operation is very cumbersome and time-consuming, which not only reduces the system. Update efficiency, and reduce system maintenance costs, thereby reducing user experience
