摘要： The subject invention provides an apparatus (10) for controllably programming an EEPROM (14), thereby reducing the likelihood of an inadvertent EEPROM write. The apparatus (10) includes a first circuit (22) which repeatedly produces a pseudo address signal at a preselected frequency. A second circuit (24) receives the pseudo address signal and delivers a write-enable signal to the EEPROM (14) in response to receiving the pseudo address signal a preselected number of times. A third circuit (12) delivers an address signal and a corresponding data signal to the EEPROM (14) during at least a portion of the production of the write-enable signal. The address signal is indicative of an address location in said EEPROM (14) and the data signal corresponds to the data to be stored in the EEPROM (14) address location.

摘要： An apparatus (10) determines the playload carried in a work vehicle (12) by periodically measuring the pressure of a fluid contained within front and rear suspension struts (16, 18). The struts (16, 18) are connected in supporting relation between a load carrying portion (20) and a ground engaging portion (32) of the vehicle (12) such that a pressure differential between a loaded and unloaded vehicle (12) can be shown to be indicative of the magnitude of the payload. Moreover, the pressures are a function of the geometry of a suspension means (34) which interconnects the load carrying portion (20) and the ground engaging portion (32).

摘要： Les systèmes de commande antipatinage sont utiles notamment sur des véhicules industriels tout-terrain. Il est préférable que de tels systèmes réagissent rapidement à des conditions de travail défavorables et soient capables de produire rapidement des forces de freinage sur la roue motrice qui tourne plus vite que les autres à un moment donné. L'appareil et le procédé décrits utilisent un circuit électrique (42), destiné à produire un premier signal et un second signal de commande des freins dont les valeurs réagissent à une condition de travail dans laquelle l'une des roues (10, 12) du véhicule perd son adhérence et tourne plus rapidement que l'autre roue (10, 12) du véhicule. Une première soupape régulable (50, 52) reçoit le premier signal de commande des freins et engage de façon réactivement régulable un mécanisme de freinage (24, 26) associé à la roue tournant plus vite (10, 12), pendant qu'une seconde soupape régulable (50, 52) reçoit le second signal de commande des freins et actionne de façon réactivement régulable un mécanisme de freinage (24, 26) associé à la roue tournant plus lentement (10, 12) en le faisant passer d'une position de freinage relâchée à une position de freinage préenclenchée. Par conséquent, dès lors qu'une condition de travail glissante est détectée, chacun des mécanismes de freinage (24, 6) associés aux roues motrices (10, 12) du véhicule est mis dans un état prêt à réagir lui permettant un effort de freinage immédiat avec un temps de réaction minimum.

摘要： A diagnostic system is provided for detecting a fault condition in a transmission (115) having a plurality of rotating components (125, 130, 135), a plurality of clutches (C1-C6), and a transmission control (147). The diagnostic system includes speed sensors (150, 155, 160, 165) producing speed and direction signals representative of the rotational velocity of the rotating components, a processor (147) for calculating the relative rotational speed between two or more clutches and for indicating a fault condition in response to the relative rotational speed and a period of time.

摘要： Anti-spin control systems are useful, for example, in industrial off-road vehicles. It is desirable that such systems exhibit rapid response to adverse working conditions, and be capable of quickly applying braking forces to whichever driven wheel is rotating at a higher velocity at a given time. The instant invention includes an electrical circuit (42) for producing first and second brake control signals having values responsive to a working condition wherein one of the vehicle wheels (10, 12) loses traction and rotates more rapidly than the other vehicle wheel (10, 12). A first controllable valve (50, 52) receives the first brake control signal and responsively controllably engages a brake mechanism (24, 26) associated with the faster rotating wheel (10, 12), while a second controllable valve (50, 52) receives the second brake control signal and responsively controllably moves a brake mechanism (24, 26) associated with the slower rotating wheel (10, 12) from a brake released position to a brake pre-engaged position. Therefore, upon detecting a slippery working condition, each of the brake mechanisms (24, 26) associated with the driven wheels (10, 12) of the vehicle is brought into a state of readiness for immediate braking effort with minimal time delay.
