Double-wheel automotive hand control system

摘要

Disclosed is an automotive control system for use by handicapped drivers who have lost the functional mobility of the lower extremities. A second wheel concentric with the steering wheel is added such that it is reachable by either the thumb or fingertips when hands are on a steering wheel in normal driving fashion. Movement of this second control wheel in a direction away from the driver actuates the automotive braking system through an electro-hydraulic servo system. Pulling the second wheel towards the driver actuates the throttle of the automobile through a similar servo system. The brake and throttle servos interface with existing automotive control systems such that little additional "add on" mechanisms are necessary.
