Technical Field
The invention relates to the technical field of vehicle remote starting, in particular to a vehicle remote pre-starting method based on decentralization.
Background
In order to improve the comfort and safety of vehicle driving, vehicle remote start technologies have been developed for remotely starting a vehicle. For example, in hot weather, particularly when the vehicle is parked outside for insolation, the temperature in the vehicle is very high, and the vehicle owner cannot normally drive the vehicle at the time, so that the vehicle-mounted air conditioner needs to be started to reduce the temperature in the vehicle before entering the cab. For another example, in cold weather, especially when the vehicle is parked outdoors in winter, the difference between the outside temperature and the inside temperature is large due to the temperature difference between the outside temperature and the inside temperature of the vehicle passing through the day and night, which causes the frosting on the windshield of the vehicle and affects the driving view of the vehicle owner, and at this time, the vehicle must be started first, so that the inside temperature and the outside temperature are balanced, and then the vehicle is heated.
However, in the current vehicle remote starting strategy on the market, a sending end directly sends a starting instruction to an in-vehicle communication module, and the in-vehicle communication module receives the instruction and simply verifies the instruction to control the vehicle-mounted air conditioner to adjust. It can be seen that the existing vehicle remote start technology lacks a security verification strategy for remote control instructions, and since the sending end directly performs data interaction with the vehicle, the authentication information of the control instructions and the ID addresses of the vehicle are directly leaked after the instructions sent by the sending end are intercepted, so that the security of the vehicle is threatened. Moreover, the existing vehicle remote start strategy lacks consideration on convenience of vehicle owners, the vehicle owners often need to search navigation routes by themselves after getting on the vehicle, and the vehicle is idle for a period of time in the process of remote start, so that the idle time is not well utilized to save time cost of the vehicle owners.
