  • Patent number: 8060287
    Abstract: Braking control for a hybrid vehicle provides both service and regenerative mode braking for the driven wheels. A hybrid drive system is coupled to the driven wheels to provide traction power and which is capable of operating in a regenerative braking mode. The service brakes are provided by pneumatically actuated service brakes coupled to the driven wheels. Braking is initiated conventionally using an operator controlled brake actuator. A pressure regulator is placed in a pneumatic brake actuation line coupled from the operator controlled brake actuator to the pneumatically actuated service brakes for the driven wheels. The pressure regulator initially closes during braking, preventing operation of the service brakes up to the limit of the ability of the hybrid drive system to absorb torque for regenerative braking. When the torque limit for the hybrid drive system is reached, the regulator opens the actuation line progressively allowing the service brakes to supplement the hybrid drive system.

  • Patent number: 7017979
    Abstract: The invention is a door opening apparatus for the outside door of a luggage or storage compartment of a large motor vehicle, such as a truck or bus. The door opening apparatus has at least one door guide and a guide roller. The door guide has tracks within a straight section and opposite first and second ends. Both tracks have a detent located within the second end of the door guide. The upper track also has a hook with a stop located within the first end of the door guide. Rollers connected to the fingers of the guide roller engage the tracks of the door guide to allow the door to move from an open to a closed position.

  • Patent number: 6764207
    Abstract: A mirror head assembly for mounting adjacent to or at a distance from exterior surfaces of a vehicle. The mirror head assembly includes one or more mirrors that enable a person to view areas surrounding the vehicle that the person could not easily view via a direct line of site. One or more lights are mounted to an outer shell of the mirror head assembly. The outer shell of the mirror head assembly may be constructed with a narrow portion disposed between adjacent mirrors so that the mirror head assembly presents less obstruction to the view of persons in the vehicle of areas surrounding the vehicle.
