Patent number: 8544964Abstract: A brake control system is provided for a utility vehicle having manned and unmanned operational modes. The brake control system includes a hydraulically operated brake. A manually operated brake circuit and an electro-hydraulic (E-H) brake circuit are connected to the brake. The E-H brake circuit includes a pump, a solenoid operated inlet valve, an accumulator, and first and second solenoid operated brake valve connected between the brake and the inlet valve. A first CPU is operatively connected to the inlet valve and to the first brake valve. A second CPU is operatively connected to the inlet valve and to the second brake valve. An accumulator pressure sensor senses the accumulator pressure. A brake pressure sensor senses brake pressure. The first and second CPUs control the inlet valve and the brake valves as a function of the sensed accumulator pressure and brake pressure.Type: GrantFiled: June 29, 2010Date of Patent: October 1, 2013Assignee: Deere & CompanyInventors: Andrew Karl Wilhelm Rekow, Troy Eugene Schick, Richard Vallieres, Timothy Diller

Publication number: 20100286845Abstract: A fail-safe system is provided for an autonomous vehicle. The vehicle has a source of electrical power and electrical loads. The fail-safe system includes an operator controlled remote unit, a wireless transmitter connected to the remote unit for transmitting a wireless keep alive signal, a wireless receiver mounted on the vehicle for receiving the keep alive signal and a fail-safe unit connected to the receiver. The fail-safe unit includes first and second processing units, both connected to each other, to the receiver and to relay units which are operable to connect and disconnect the source of electrical power from the electrical loads in response to a signal from one of the processing units. Both processing units are operable to open their respective relay units and shut down all vehicle operations in response to a variety of fault conditions, including loss of the keep alive signal from the remote unit.Type: ApplicationFiled: May 11, 2009Publication date: November 11, 2010Inventors: Andrew Karl Wilhelm Rekow, Joseph Paul Kearney

Publication number: 20090326763Abstract: A method for providing real-time, towed implement compensation comprises dynamically calculating an implement offset relative to a targeted track for an implement located at a first implement location. Based on the calculated implement offset, a vehicle offset is dynamically calculated relative to the targeted track for a vehicle located at a first vehicle location. The method further includes dynamically calculating a modified vehicle offset relative to the targeted track based on the calculated vehicle offset and based on a dynamically-calculated vehicle lateral error. The method further includes dynamically providing a steering control signal based on the calculated modified vehicle offset.Type: ApplicationFiled: June 5, 2009Publication date: December 31, 2009Inventor: Andrew Karl Wilhelm Rekow

Patent number: 7062381Abstract: A primary transceiver of a primary vehicle transmits a first transmission signal to a first transponder and a second transponder associated with a secondary vehicle. A first transponder antenna and a second transponder antenna are associated with secondary vehicular reference points. Upon receipt of the first transmission signal, the first transponder transmits a second transmission signal to a first beacon of the primary vehicle and the primary transceiver. A transmitter antenna and the first beacon antenna are associated with primary vehicle reference points. Upon receipt of the first transmission signal, the second transponder transmits a third transmission signal to the first beacon and the primary transceiver. A data processor or estimator determines propagation times associated with the first transmission signal, the second transmission signal, and the third transmission signal.Type: GrantFiled: August 30, 2005Date of Patent: June 13, 2006Assignee: Deere & CompanyInventors: Andrew Karl Wilhelm Rekow, Scott Adam Stephens

Patent number: 6732024Abstract: The present invention provides for a method and apparatus for providing navigation and positioning for at least one or more slave vehicles, wherein the slave vehicles provide their own navigation based on a location of a master vehicle. The method and apparatus allow a slave vehicle to receive a location of a master vehicle and a location of the slave vehicle. Once the location of the vehicles are known, the slave vehicle determines a desired position based on the master vehicle location, determines if adjustments are needed to position the first slave vehicle at the desired position and implements the adjustments if adjustments are needed. The slave vehicle is capable of operating in one of a plurality of modes and further is capable of transitioning from a first mode of operation to a second mode of operation in optimizing navigation and control.Type: GrantFiled: May 7, 2001Date of Patent: May 4, 2004Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Andrew Karl Wilhelm Rekow, David Mark Bevly, Bradford W.
