Ford has been granted a patent in the United States for a system it calls ‘Non-Autonomous Steering Modes’, which would allow an autonomous car to be steered using a smartphone.
First discovered by carbuzz.com, Ford’s patent allows the vehicle to be controlled through the accelerometer and gyroscope within most smartphones. The same system is used to control cars in video games like Real Racing, but hasn’t yet made the leap to reality for reasons we probably needn’t explain here.
The patent outlines two ‘modes’ for the system. The first mode involves establishing a connection between the smartphone and the car, at which point the user would be asked to align their device with the vehicle’s zero steering angle. At this point, the user will be handed control of the steering systems.
From then, the accelerometer and gyroscope housed within the device would sense the movement, gravity and angle at which the device is being held, and relay that information to the car’s systems.
The second mode outlined in the patent involves a virtual steering wheel shown on the device’s screen. To enable this mode, the user would be asked to align the virtual steering wheel with the angle of the car’s front wheels.
