A control for enhanced range shifting in a computer () assisted vehicular compound transmission having a main section (A) shifted by a manually operated shift lever () and a range section (B) shifted in response to operation of a range shift selector, such as sensing shift lever () passing through a predetermined actuation point (AR) in the shift pattern. During a compound up-shift, if the vehicle reaches a speed greater than a predetermined value during a coasting condition and the shift lever is in a low range neutral position, then the range section up-shift is automatically completed without undue wear or damage to the range section synchronized clutch (). It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1. 72(b).

A system and method for completing an automatic up-shift during an engine progressive governor event in a controller-assisted, manually shifted compound transmission system () and splitter shift control therefor. Auxiliary splitter section (B) shifts are automatically implemented by a splitter shifter () under commands () from a controller (). The controller () overrides the engine governor control and controls engine torque to approach, and preferably reach a zero torque condition and bring the transmission to a splitter-neutral condition to enable an automatic up-shift when the splitter button has been selected or lever shift has been moved by the operator. Depending on the type of shift event, the transmission will automatically complete the upshift or the operator can manually complete the upshift after engine synchronization. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1. 72(b).

74335

A system and method for predicting a destination gear for engine and transmission control is described. Auxiliary splitter section (B) shifts are automatically implemented by a splitter shifter () under commands () from a controller (). The controller () includes logic rules for determining an expected front box gear and determining whether an intended shift is one of a button shift and a compound shift. When a compound shift is intended, a shift lever lateral position, a shift lever fore-aft position, and a splitter switch position are used to determine the predicted destination gear. The controller () can use the predicted destination gear for engine and splitter control. It is emphasized that this abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

74335

A control for enhanced shifting in a computer (48)-assisted vehicular compound transmission system having a having a main section (16A) shifted by a manually operated shift lever (31). The system is controlled as a function of current main section engaged or neutral condition sensed as function of shift lever vertical position in an H-type shift pattern. A position sensor (160) is provided for sensing the position of the shift lever in the shift pattern. Logic is provided to vary, as a function of vehicle operating conditions, the location/width of the bands of vertical positions (202/204) considered to be indicative of a main section neutral condition.

A control system for controlling splitter jaw clutch (88) engagement and disengagement forces during a splitter section (16B) shift. The splitter section is shifted by a variable force splitter actuator (142) and is preferably capable of asserting at least a low, medium and high force to the splitter jaw clutch members.

324388

An improved system and method for detecting solenoid-related faults in a solenoid-controlled actuator assembly. The system includes a processing circuit which controls a solenoid driver circuit for energizing and de-energizing the solenoid, a current sense circuit for sensing the current in the solenoid, and a power supply switching circuit for selectively connecting and disconnecting a supply voltage from the solenoid driver circuit. The processing circuit implements fault detection logic wherein the processing circuit senses the current in the solenoid and, if the sensed current exceeds a predetermined current value for a predetermined time period, disconnects the supply voltage from the solenoid driver circuit and measures the rate of voltage decay in the solenoid driver circuit to determine if an open circuit fault or a short circuit fault exists.

A transmission shifting mechanism (10) and position sensor assembly. The shifting mechanism includes a member (32) of known flux-conducting or flux-insulating properties movable therewith, which will variably extend (42, 44, 46) into an electric coil (36), which is periodically charged and then allowed to discharge. The rate of discharge is variable with the position of the member in the coil and, thus, provides a signal indicative to mechanism condition (H, N, L).

74745

A robust control (10) for a pressurized-fluid-operated, three-position shift actuator piston assembly (12). The system requires only a single controlled source of pressurized fluid (44) to provide movement to and retention in a selected one of three axially displaced positions (D, N, OD). A solenoid-controlled valve (42) is controlled by pulse width modulation. Current applied to the solenoid coil is controlled (46), voltage (V) applied to the solenoid coil is sensed and used as a control parameter and/or a relatively light detent (48, 50) biases the assembly to a neutral (N) position to provide a robust control.
