Claim 5:
6. A method for controlling a steering system of a vehicle during an autonomous steering development mode, comprising:
performing, by one or more computing devices, high-authority autonomous steering control of a steering system of the vehicle, the high-authority autonomous steering control preventing an operator from directly taking over steering control;
receiving, by the one or more computing devices, a request to exit autonomous steering control;
transitioning, by the one or more computing devices, from the high-authority autonomous steering control to low-authority autonomous steering control of the steering system for a predetermined time period in response to receiving the request to exit autonomous steering control, the low-authority autonomous steering control allowing an operator to directly take over steering control; and
exiting, by the one or more computing devices, the low-authority autonomous steering control and enabling manual steering control of a manual input device of the steering system when at least one of another request to exit autonomous steering control is received before the predetermined time period elapses or an input from a braking system of the vehicle is received.
