A method for generating and verifying an output command for using in a power steering system is provided. The method receives, by a module having at least a primary processing path and a secondary processing path that is in parallel with the primary processing path, a set of input signals. In the primary processing path, the method generates a primary output command based on the set of input signals and sends the primary output command out of the module. In the secondary processing path, the method generates a first range of command values based on the set of input signals, determines whether the primary output command falls within the range of command values, and generates a fault signal based on determining that the primary output command does not fall within the first range of command values. | ||||||

66 | Agricultural vehicle | US998367 | 1992-12-30 | US5335739A | 1994-08-09 | Ian Pieterse; Nicolaas Snyman; Andre Minne |
A high crop agricultural vehicle has a chassis supported at an elevated position on front and rear sets of wheels. The front wheels are turnable through an arc of greater than 90.degree. so that they can be turned to a lateral travel position which is perpendicular to the direction of normal forward travel. In that lateral travel position the vehicle can be driven sideways. This allows the vehicle to be easily manoeuvred as well as facilitating the mounting of agricultural implements into the space between the front and rear wheels. The rear wheels are preferably momented in a castor-type mounting assembly. | ||||||
67 | Automated control system for traction vehicles | US149851 | 1988-01-29 | US4850249A | 1989-07-25 | Gerhard Kirstein |
A control system is provided for a traction vehicle having a coupling for towing a trailing vehicle load. The system includes a microprocessor which receives signals from a load sensor and, as a function of such signals, controls the slip duration of shifting clutches in an automatic gear shift mechanism as well as the gear speed ratio timing and shifting sequence. In addition, the control system limits the minimum turn radius of the traction vehicle when pulling a load and prevents excessive acceleration of the traction vehicle when not coupled to a load. | ||||||
68 | Automatic synchronized pitch controls for pairs of driver and driven V pulley drives | US516381 | 1974-10-21 | US3964327A | 1976-06-22 | Andrew Oscar Siren |
In a vehicle or the like, a source of power is connected to a drive shaft. Two pairs of pulley halves are splined to this shaft and can be moved apart and together and are rotated by the shaft. Driven shafts also carry pairs of pulley halves which are splined thereto and can be moved therealong and belts extend between corresponding pulley halves on the drive shaft and corresponding pulley halves on the driven shafts. A pair of spur gears are journalled for partial rotation and mesh with one another, there being one pair for each two sets of pulley halves and a third drive gear engages between the innermost gears of said spur gears so that movement of this drive gear causes equal and simultaneous rotation of the spur gears. Levers are secured to the spur gears and are operatively connected to the pulley halves so that when the drive gear is rotated, one of the sets of pulley halves are moved apart on one of the shafts whereas the other set are moved together by equal amount and vice versa. This permits belts extending between the sets of pulley halves to increase or decrease the speed of the driven shafts. The drive gear is connected to a steering mechanism and with the driven shaft being connected to the drive wheels on each side of the vehicle, easy and accurate steering is accomplished by speeding up one set of drive wheels and decreasing the speed of the other and vice versa. A winch assembly is connected to the drive shaft by a similar arrangement thus enabling the speed of the winch to be controlled accurately which is of particular importance when the winch is being used to disengage the vehicle from mud, snow or the like under which circumstances the winch speed can synchronize exactly with the speed of the drive wheels so that both the winch and the drive wheels can assist in extracting the vehicle from the mired position. | ||||||
69 | Snow cat | US433940 | 1974-01-16 | US3937289A | 1976-02-10 | Lawrence Chapman Dickinson |
A vehicle adapted to traverse snow-covered areas, commonly called a "snow cat," is disclosed. The snow cat of the present invention includes fore and aft substantially rigid body frame members. An articulating joint joins the fore and aft body frame members and permits relative rolling motion and yawing motion respectively between the two rigid members. Yawing motion at the joint is controlled manually to steer the vehicle. Two track assemblies are mounted on each side of both the fore and aft body frame members. Each track assembly includes a relatively wide endless track having a moving flat base portion which rides over snow. A track assembly having a plurality of rows of rollers is disclosed for maintaining the base portion in its substantially flat configuration. The drive sprocket for each track assembly is located slightly above and intermediate the rollers so that the track is maintained in a triangular configuration. Fore and aft torsion bars provide stabilizatiton between the two forward track assemblies and the two aft track assemblies respectively. | ||||||
70 | Coaxial gear system for bellyless vehicles | US44895774 | 1974-03-07 | US3908482A | 1975-09-30 | KEHLER PAUL |
A coaxial gear system for the powering of bellyless vehicles, comprising a set of coaxially mounted differential gear trains, said gear trains comprising two input shafts and one output shaft, said output shafts rotating at an angular speed that is intermediate the speeds of the two input shafts, with each of the gear trains designed to allow connection of its output shaft to input shafts of the two adjacent differential gear trains of the coaxial set, and to allow connection of its two input shafts to the output shafts of the two adjacent differential gear trains of the coaxial set.

71 | Dump valve and forward-reverse drive control employing same | US81885769 | 1969-01-23 | US3831721A | 1974-08-27 | SHORE D |
Tractor having dump valve and forward-reverse drive control employing same, effective to automatically brake the tractor when the tractor''s direction of motion is to be reversed. The tractor has brakes and a reversible transmission controlled by the dump valve, a run detector pump to sense direction of rolling movement of the tractor and having a directionalized pump output, and a range selector valve having a control portion. By suitable interaction with the other components, the dump valve receives against pressure movable end areas thereof an output from the range selector valve and directs control pressure to operate the brakes and transmission in alternation to one another. More specifically, the dump valve: receives against the pressure movable end areas the directionalized pump output so as to be hydraulically balanced in a centered position operating the tractor with transmission engaged and brakes disengaged; receives against the pressure movable end areas an unbalancing force from the range selector valve control portion (due to reversal of the range valve position) causing the dump valve to shift off center and dump, neutralizing the transmission and setting the brakes; and having valve springs effective to mechanically rebalance the dump valve attendant with slow down of the run detector pump, causing the dump valve to recenter, releasing the brakes and engaging the transmission in an opposite drive setting.
