A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The roll angle facilitates correction of the lateral motion induced position errors resultant from motion of the antennae as the vehicle moves based on an offset to ground and the roll angle. Alternative aspects include multiple-antenna GNSS guidance methods for high-dynamic roll compensation, real-time kinematic (RTK) using single-frequency (L1) receivers, fixed and moving baselines between antennas, multi-position GNSS tail guidance (“breadcrumb following”) for crosstrack error correction, guiding multiple vehicles and pieces of equipment relative to each other, and snow grooming equipment and method applications.

A system and method for controlling access to a work vehicle includes limiting an unauthorized operator's access to the work vehicle by disabling an engine subsystem and additionally limiting access to another vehicle system such as an auxiliary fluid actuator, by disabling at least one of the auxiliary fluid actuators.

A track cleaning system mounted on a railcar and comprising track rail cleaning nozzles, leaf removal nozzles and third rail cleaning nozzles. Each of the nozzles may provide a fan-shaped spray pattern diverging to either side of a central axis and having a major axis. For each track rail nozzle, the central axis may be perpendicular to a horizontal top rail surface and the major axis may be perpendicular to the rail surface centerline. For each leaf nozzle, the central axis may be directly downwardly from the horizontal and the major axis may be parallel to an elongated spray bar on which one or more leaf nozzles are mounted. For each third rail nozzle, the central axis may be directed downwardly from the horizontal and the major axis may be positioned vertically. The third rail nozzles may be mounted to the rear of the leaf nozzles to aid in leaf removal. Main water valves are remotely actuated by air to release high pressure water to corresponding sets of nozzles. A pressure control valve controls the pressure of water supplied to the main water valves from a positive displacement, high pressure water pump.

This method provides various high-power-ratio snow removal devices which clear paths narrower than the motor vehicles. We use small, light, low-priced, yet also safe, durable devices to clear the narrow swaths. High power ratios result from applying motor vehicle horsepower to small snow removal devices similar to those found on lawn tractors. Such devices may comprise moldboard plows (FIGS. 3, 9, 10, 11, 15, 16), snow throwers (FIGS. 7 and 13), or combinations of both types (FIG. 12 and 17). Quick-connect and quick-release fittings (FIGS. 3A, 3B, 6, 8, 9A, 9B, 14) position each device for temporary propulsion by a vehicle. The connectors allow quick conversion of the family car to a plowing machine, and when plowing is done, quick re-conversion. A moldboard plow of about half the car's width (FIG. 3) is our preferred embodiment. The mini-moldboard (FIG. 10) is least expensive. Deepest snow can be handled by our tall, narrow moldboard (FIG. 15). We protect homeowners, their cars and their plows from injury when plows strike hidden objects. Protection devices comprise safety springs (60) and pivots (63, 67 and 69) of FIG. 3B, the tension-release mechanism mentioned but not detailed in FIG. 15, annor shields (396, 398) of FIG. 16 and various others mentioned or provided for in our drawings but not detailed. We prefer cars' chassis tie-down ears (72) in FIG. 3A, as connector points for our plow or thrower arms. For cars lacking such ears, we propose add-on ears. For example, tie-down ear (126) in FIG. 6.
