Ford patents a system through which you can drive a car by mobile phone (6/7)

Ford Motors have patented a system (non-autonomous steering modes) through which a touch-screen device can be converted as a steering system for a vehicle.

One of the ways which Ford has envisaged is turning the device in to a steering wheel. Control from the vehicle steering system could be passed on to the device through a request, and then a ‘base position’ is determined for the steering wheel after the vehicle and device are in sync.

The device then can be used as a steering wheel.
