Title: Parking brake invalift interlock system
Inventor: VINSON HARRY L
IPC: B60T7/12
Filed: 2003-01-09
Abstract: A parking brake invalift interlock system that includes electrical communication with a park brake solenoid valve. This solenoid valve in a closed position will prevent air from releasing the park brakes. The solenoid valve is engaged to the circuit of the interlock system such that the valve cannot be opened to release the park brake unless the vehicle ignition is in an ON or energized position, the lift is stowed, and the lift door is closed. The invalid or wheelchair lift, referred to as an invalift, is electrically engaged through the interlock system to the ignition system, a park brake pressure sensor, and a lift door position sensor. As a result, the invalift lift control cannot be operated unless the ignition is ON, there is power to a Lift Switch, the park brake system fluid or air pressure is below a predefined pressure setpoint, and the lift door is opened. The system may further be configured to prevent lift door opening unless the ignition is in the ON position. This would be to ensure that the lift has the power to operate.

Title: System and method for steering a multi-wheel drive vehicle
Inventor: STROTHMANN THOMAS
IPC: B62D9/00
Filed: 2002-01-15
Abstract: A system and method of controlling a multi-wheel drive vehicle is provided.  The invention is preferably applicable to the steering of such a vehicle and determines the individual velocities for each wheel drive (108, 110, 112, 114). In this regard, the invention includes two general steps. The first step includes determining the distance of each wheel drive (108, 110, 112, 114) and a vehicle velocity reference point from a turning reference point. The second step includes ratioing each wheel drive's distance from the turning reference point with the vehicle velocity reference point's distance from the turning reference point. The ratios are then applied to a vehicle velocity associated with the vehicle velocity reference point to determine the velocity of each respective wheel drive.(108, 110, 112, 114). Once determined, the velocities are output to each wheel drive.(108, 110, 112, 114)
