Abstract: A steering control assembly including: a base configured to couple with a steering shaft; a ring mounted to the base and configured to rotate independent of the base; a locking member movable between a locked configuration and an unlocked configuration, in the locked configuration the locking member locks the ring to the base to restrict rotation of the ring independent of the base, and in the unlocked configuration the ring is free to rotate independent of the base; and a handle mounted to the ring and rotatable with the ring independent of the base when the locking member is in the unlocked configuration to adjust a radial position of the handle relative to the base, the handle configured to be grasped by a user to rotate the steering control assembly and the steering shaft when the locking member is in the locked configuration.

Abstract: A system for actuating a brake pedal and an accelerator pedal of a vehicle by hand. The system includes a planetary gear train having a sun gear, a ring gear, and planetary gears meshed with both the sun gear and the ring gear. The planetary gears are mounted to a carrier. A carrier flange is in cooperation with the carrier to rotate with the carrier. A sun gear flange is in cooperation with the sun gear. Rotation of the sun gear flange rotates the sun gear. A lever is mounted adjacent to the sun gear flange. An accelerator actuation assembly is connected to the lever and configured to couple with the accelerator pedal. A brake actuation assembly is connected to the carrier flange and configured to couple with the brake pedal.
