| 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. | ||||||

| 107 | Worm drive hydraulic automatic transmission | US564875 | 1975-04-04 | US4016778A | 1977-04-12 | John W. VON Greyerz |
| This disclosure is directed to an improved transmission providing a substantially infinite motor to drive axel gear ratio capable of automatically adjusting itself under a wide variety of conditions. The transmission of this invention is comprised of three distinct operational units, the torque converter or fluid drive, the worm drive unit and the gear box unit. The transmission while in drive, is capable of providing substantially an extreme low motor to rear wheel ratio which can vary through any ratio necessary under particular driving conditions up to approximately a 1-to-1 ratio. | ||||||
| 108 | Transmission control system | US3705642D | 1971-02-12 | US3705642A | 1972-12-12 | THOMPSON CHARLES H |
| There is disclosed a control system providing manual and also automatic shift control for a multispeed forward and reverse track-laying vehicle transmission. The automatic operation is provided by pilot valves which are controlled by a pressure indicative of vehicle speed and also a pressure indicative of engine torque demand to condition shift valves to effect shifting between all of the forward drives. The manual control is provided by solenoid valve control over the bias of the shift valves to effect manual shifting with downshifting to lower speed range drives being delayed until vehicle speed is suitable for the speed range of the selected lower drive. The transmission includes a torque converter having a lockup clutch whose engagement is effected with the fluid delivery used for the selected drive engagement with the lockup clutch engagement being momentarily interrupted on shifting between certain of the forward drives by shuttle valve operation. A neutral valve whose operation is controlled by solenoid valves operates to deliver fluid to the shift valves for the drive engagements and on interruption of electrical power to its solenoid valves, operates to automatically condition the transmission in neutral but if the transmission is providing drive and there then occurs loss of power to these solenoid valves, the neutral valve continues to permit the establishment of transmission drive. The control system further includes a directional valve which is operated by solenoid valves to control the engagement of devices that are necessary to establish forward and reverse drive. When there is loss of power to the directional valve''s solenoid valves, the directional valve remains in its preselected position. A forwardreverse inhibitor valve prevents the directional valve from effecting shifting between forward and reverse above a vehicle speed suitable for such shifting. The control system also includes a brake coolant valve which is controlled by a brake apply valve to deliver fluid to cool the transmission''s two output brakes with a normal fluid supply that originates at an input driven pump and is supplemented by operation of a diverter valve that delivers flow from output pump after higher fluid supply priorities are set.
