摘要： An apparatus determines the payload carried in a work vehicle by periodically measuring the pressure of a fluid contained within front and rear suspension struts. The struts are connected in supporting relation between a load carrying portion and a ground engaging portion of the vehicle such that a pressure differential between a loaded and unloaded vehicle 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 which interconnects the load carrying portion and the ground engaging portion.

摘要： In one aspect of the present invention, a method for controlling an interrupted shift for a powershift transmission is disclosed. The method first determines which clutches are active and then classifies each of the active clutches. Thereafter, the method calculates the timing associated with the engagement and disengagement of the classified active clutches to result in a smooth transition to the final selected gear.

The apparatus includes a first circuit which repeatedly produces a pseudo address signal at a preselected frequency. A second circuit receives the pseudo address signal and deliveries a write-enable signal to the EEPROM in response to receiving the pseudo address signal a preselected number of times. A third circuit delivers an address signal and a corresponding data signal to the EEPROM 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 and the data signal corresponds to the data to be stored in the EEPROM address location.

摘要： Anti-wheel spin control systems are useful, for example, in industrial off-road vehicles. It is desirable that such systems operate automatically and not be unduly influenced by false slip signals caused by steering of the vehicle. It is further desirable that the operability of the control be readily determined by the operator. The instant anti-spin control includes an apparatus for producing a slip signal having a value responsive to the difference in rotational velocity between the vehicle wheels, and for producing a test signal. A processor receives the slip signal and test signal, compares the slip signal value with a first predetermined reference value in response to receiving the slip signal in the absence of the test signal, and compares the slip signal value with a second predetermined reference value in response to receiving both the slip signal and the test signal. A brake control signal is produced in response to the slip signal value exceeding the compared reference value, and the braking mechanism corresponding to the slipping wheel is activated. In a second embodiment of the invention, a steer signal is also produced and applied to the processor. The steer signal is utilized to negate the effect of steering the vehicle on the produced slip signal. Thus, the disclosed anti-spin system accounts for false slip indications produced by steering the vehicle, and provides a ready means for the operator to test the operability of the control system.
