A method for controlling a transmission includes using actuation of a button of a shift module to produce a signal representing a desired gear, using the signal and a second signal commanding a park range to determining a priority range, using a shift mechanism to attempt engagement of the transmission in the priority range, and if the priority range is park and park is not engaged, engaging a park brake.

Control of automatic transmission shift by wire range selection

A magnetic field sensor is employed to determine a rotational velocity of an element by sensing frequency variations in a magnetic flux during rotation of the element. The magnetic field sensor includes a sensor face provided with obstacles, such as a series of spaced, substantially parallel grooves arranged perpendicular to a direction in which contamination tends to move across the face during operation of the sensor. The obstacles inhibit movement of contamination across the face such that the contamination does not cause false variations in the magnetic flux which would degrade sensor signals.

A method and system provides a Neutral Hold mode in a vehicle having a shift-by-wire transmission with a return to park feature. The Neutral Hold mode is entered upon detecting when the transmission control mechanism has been used a first time to select Neutral when a driver's door is open or has been used a second time to select Neutral. When in Neutral Hold mode, the transmission will stay in Neutral and not shift to Park upon detecting that a driver has exited the vehicle.

Method and system for providing a neutral hold mode in a shift-by-wire transmission

A method and system provides a Neutral Tow mode in a vehicle with a shift-by-wire transmission by displaying a Neutral Tow mode option when the transmission control mechanism has been used to select Park, an ignition switch is on, and an engine is off or an information button has been pushed and entering a Neutral Tow mode upon detecting a triggering event. The Neutral Tow mode is canceled upon detecting a certain sequence of events, such as turning on the ignition switch, depressing and holding a brake pedal, and selecting Park. When in Neutral Tow mode the transmission will stay in Neutral, without automatically shifting to Park or using battery power, thereby enabling the vehicle to be towed long distances without draining battery power.

A system for shifting a transmission range includes a selector producing a signal representing a selected range, and the system has a primary state wherein a source of electric power shifts the transmission to the selected range in response to the signal, and a secondary state wherein a source of mechanical energy shifts the transmission to a Park range when the primary state is unable to shift the range.

Range shifting of an automatic transmission

A method and system provides a Brake Transmission Shift Interlock Override mode in a vehicle including a shift-by-wire transmission. With power applied and ignition on, a driver will press and hold an override switch for a calibrated time. While the override switch is pressed, the driver presses a non-Park button for another calibrated time. The result will be that the vehicle is placed in the selected range wherein the transmission will not automatically shift to Park upon detecting a triggering event. The driver is able to shift the vehicle from Park, even if an electrical failure prevents the transmission from shifting out of Park. As such the vehicle can be driven until the failure is serviced.
