    Abstract: A method of determining a current operating range of a transfer case includes continuously calculating current Combined Drive Ratio (CDR), and categorizing the current CDR into one of a pre-determined number of expected CDRs. Counters are used to track when the current CDR is identified as an expected CDR. The different counters are then analyzed using simple mathematical operations to identify which gear ratio the transfer case is currently operating in.

    Abstract: A voting strategy is used to determine the mode state of a transmission when a vehicle is restarted. The transmission includes a return to park feature and a controller including at least three memories. The controller is configured to write a remembered mode state into each memory. The remembered mode state is one of a Normal mode state that allows the transmission to automatically shift to Park, a hold mode state that causes the transmission to remain in Neutral and not automatically shift to Park upon detecting a triggering event or other mode states. The controller reads each memory and, when at least two of the remembered mode states are the same mode state, causes the transmission to enter a mode state corresponding to the same mode state.

    Abstract: An electronic control unit senses an actual shift range of a automatic transmission by executing a range determination operation, which determines the actual shift range of the automatic transmission based on a rotational position of a manual shaft that is sensed with an encoder. The control unit prohibits the execution of the range determination operation throughout a range determination operation prohibiting period, which is a predetermined time period and starts from a time point of starting rotation of the rotor of the electric motor unit toward the target rotational position.

    Abstract: A manually shifted multi-step transmission for motor vehicle having a main transmission and a group transmission embodied as a range group. The shifting of the gears occurs according to a “simple H-shaped shift pattern” by way of a manual shift lever which is moved in shift gates or in a selector gate, and the range group can be shifted into a “high” range stage and into a “low range stage”. The range group can be shifted automatically by way of a control device having a rotational speed sensor which detects the transmission output rotational speed, and a sensor which detects the shift gate of the gear to be shifted.

    Abstract: A work vehicle with a speed change device, comprises, a plurality of wheels including at least one driven wheel; an engine for driving the driven wheel; a speed change device provided between the driven wheel and the engine; and automatic shifting mechanism. The automatic shifting mechanism is capable of operating the speed change device to a lower speed position within an automatic shifting range having a predetermined range and is capable of operating the speed change device up to a speed position which the speed change device was in before an operation to the lower speed position was effected, in response to load on the engine. The entirety of the automatic shifting range is changeable to a low speed side and to a high speed side or the automatic shifting range can be widened to include more speed positions and narrowed to include less speed positions.
