A new Apple patent reported by Patently Apple suggests a possible new addition the company might make to the iPhone’s “Do Not Disturb while Driving” feature. First introduced in iOS 11, Do Not Disturb while Driving allows users to automatically engage a special Do Not Disturb mode that not only silences incoming notifications, but suppresses them from the lock screen entirely to remove the temptation for users to check their iPhone while in the car. Users can also configure an automatic reply in Messages that will be sent to contacts when this mode is engaged, and this is where Apple’s new patent comes in. Patent application 20180146089, titled “Intelligent Digital Assistant for Declining an Incoming Call” would allow Siri to notify the user of an incoming phone message and allow them to dictate a short response that could be sent back to the caller. The response could also include not only text, but also a voice recorded message, a map location, or even a copy of the user’s calendar. Siri could also conceivably answer the call on the user’s behalf to let the caller know that the person is driving. Of course, as with all Apple patents, the mere indication of a patent doesn’t mean that an implementation of it will ever see the light of day, but this one seems like a logical extension of the iPhone’s Do Not Disturb feature.
