This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0136097, filed in the Korean Intellectual Property Office on Oct. 12, 2023, the entire contents of which are incorporated herein by reference.
The present disclosure relates to a smart key wireless update control apparatus and a method therefor, and more particularly, to a technique for wirelessly updating software of a vehicle smart key.
With development in the vehicle industry, development of a system to provide various services using a wireless communication technique is continuously being made in order to provide convenience to a driver. For example, a vehicle may update software of a controller mounted on the vehicle through wireless communication (over the air (OTA)).
During an update of software of a controller of such vehicles, a vehicle communication module receives information related to the update from an OTA update server, and the vehicle communication module transmits information related to the update to an internal update target controller.
However, in a case of a smart key, in response to a case where quality problems occur or software changes are required, such as function addition, wireless or wired reprogramming is not possible. Thus, quality and functionality could be improved by replacing the product itself.
Accordingly, in replacing a smart key, there is the inconvenience of having to visit the service center in person. Also, in replacing a product, there is a problem that costs are excessive due to both part costs and various labor costs.
Accordingly, efforts were made to develop a wireless update method for a smart key, like a vehicle internal controller. However, in a case of the smart key, battery capacity is small, and a time that a driver is inside the vehicle with the smart key is limited. Unlike an in-vehicle controller connected to a wired network, there is a restriction that only wireless updates may be performed. Thus, there is a problem in that wireless updating of the smart key is not easy.
