A patent application filed by Apple and published today by the USPTO describes how an iPhone device could be used to locate a parked car.
The patent describes how the iPhone would be used in conjunction with a compatible car and connected to it. Apple’s CarPlay allows an iPhone to be connected to a car using a Lightning cable so that it can use its dashboard screen and on-board controls. The patent application also describes how Bluetooth could be used as a connection method. Bluetooth isn’t yet supported by CarPlay.
In the patent filing, Apple explains that the data connection could be used to send a signal to the iPhone when the vehicle moves off and when it parks, for example by using the ignition to trigger an event. The iPhone’s on-board sensors could also be used to determine when the car starts moving and when it stops.
