1. An automatic steering system for a vehicle, comprising:
an assisted steering device configured to mount to a steering wheel of a vehicle, the assisted steering device comprising a motor and an encoder, wherein the motor is offset from a steering axis of the vehicle's steering wheel when mounted, the assisted steering device further configured to determine current encoder information; and
a controller configured to operate the assisted steering device, the operation comprising:
receiving the current encoder information from the assisted steering device;
determining a desired encoder rate based on the current encoder information and a desired encoder position;
operating the motor using the desired encoder rate;
comparing a current encoder rate to desired encoder rate information; and
disengaging automatic steering control when a result of the comparison meets a manual steering condition.
