Abstract: A door check system includes a rod interconnecting a door assembly and a body of a vehicle. The door check system secures the position of the door assembly at any location along a swing path of the door assembly, between a fully open position and a fully closed position. A coil spring is disposed about the rod, with the rod extending through a central aperture thereof. An actuator is coupled to the coil spring and configured for tightening and loosening the coil spring about the rod. When the actuator tightens the spring about the rod, the spring grasps the rod and secures the position of the door assembly relative to the body. When the actuator loosens the spring from about the rod, the door assembly is free to move along the swing path.

Abstract: A semi-autonomous vehicle couplable to a parent vehicle is described, and includes a chassis supported on first and second axles coupled to a plurality of wheels, a propulsion system configured to transfer torque to one of the wheels, a steering system configured to control direction of travel of the semi-autonomous vehicle, a braking system configured to apply braking force to the wheels, a high-voltage electrical energy storage system, an extra-vehicle communications system, and an extra-vehicle sensory system. A control system operatively couples to the propulsion system, the steering system, and the braking system. A coupling device is configured to electrically couple the semi-autonomous vehicle to the parent vehicle, the coupling device consisting essentially of a high-voltage DC electrical power bus electrically coupled to the high-voltage electrical energy storage system.

Abstract: A semi-autonomous vehicle includes a chassis having a repository on a plurality of wheels, a propulsion system, a steering system, a braking system, an extra-vehicle communications system, and an extra-vehicle sensory system. A control system of the semi-autonomous vehicle is operatively coupled to the propulsion system, the steering system, and the braking system and signally connected to the extra-vehicle sensory system and the extra-vehicle communications system. A non-load-bearing coupling mechanism of the semi-autonomous vehicle includes a connector, a flexible mechanical link element and a communications link.
