Apr 30, 2004

Appl. No.:

10/836658

Inventors:

Jack P. Koski - South Lyon MI, US

Assignee:

General Motors Corporation - Detroit MI

International Classification:

G06F 19/00

US Classification:

701 61, 701 51, 701 58, 701 60, 477 15, 477 34, 477110

Abstract:

A control system and method for communicating with a transmission includes a transmission input speed sensor that generates an input speed signal. A transmission output speed sensor generates an output speed signal. A power supply supplies a total current to the transmission input and output speed sensors via a first conductor. A sensor senses the total current supplied to the transmission input and output speed sensors on the first conductor. A calculating module calculates a transmission input speed and a transmission output speed based on the total current.

US Classification:

74336R, 7447321, 477 96, 477186, 477187, 1922195

Abstract:

An electronic transmission range selection (ETRS) system for shifting a transmission range of a transmission includes an electro-mechanical park inhibit assembly that operates to disallow the ETRS system from shifting from an Out-of-Park mode to a Park mode under certain circumstances. The park inhibit assembly includes a follower having a recess defined thereon and slidably disposed within a follower bore. In one embodiment a selectively energizable solenoid assembly is mounted substantially perpendicular to the follower and operates to bias a ball into the recess when energized thereby locking the ETRS system in the Out-of-Park mode. In another embodiment the park inhibit assembly includes a selectively energizable motor assembly mounted substantially perpendicular to the follower. The motor assembly operates to enforce the Park and Out-of-Park mode of the ETRS system.

International Classification:

US Classification:

3242072, 7386113, 335205, 335238, 335295, 335304

Abstract:

A switch includes housing and a magnet that is mounted inside the housing. The magnet generates a magnetic field having magnetic flux. The switch further includes a flux concentration device that is located inside the housing and that selectively moves between first and second positions. An actuator assembly is located inside the housing and selects the first and second positions based on the input. A hall-effect device is located between the magnet and the flux concentration device and conducts a current having a first value when the magnetic flux is less than a predetermined magnetic flux threshold. The hall-effect device conducts current having a second current value when the magnetic flux exceeds the predetermined magnetic flux threshold. The first position communicates a first magnetic flux to the hall-effect device and the second position communicates a second magnetic flux that is different from the first magnetic flux to the hall-effect device.

Appl. No.:

11/402745

Inventors:

Jack P. Koski - South Lyon MI, US

International Classification:

H02H 9/02

US Classification:

361 931

Abstract:

A switch system comprising a detection device that operates in first and second modes and that conducts first and second currents based on the first and second modes, respectively. A control module input circuit outputs first and second voltages based on the first and second currents. The switch system further includes a control module that receives the first and second voltages and that compares the first and second voltages to first and second predetermined voltage ranges, respectively. Further, the control module detects at least one of a proper operation and a faulty operation of the switch system based on the comparison. The control module receives the first voltage when the detection device conducts the first current and receives the second voltage when the detection device conducts the second current.

International Classification:

F16H 59/60

US Classification:

477 97, 477 72, 477 76

Abstract:

A solenoid control system for implementation with an electronic range selection (ETRS) system that shifts a transmission range between a park position and an out-of-park position. A first solenoid assembly is operable to control a fluid valve to supply pressurized fluid to urge a valve spool toward a first position. A second solenoid assembly is operable to control a fluid valve to supply pressurized fluid to urge said valve spool toward a second position. A control module selectively energizes one of the first and second solenoids based on a transmission fluid temperature.

US Classification:

701 51, 701 52, 701 63, 477 15

Abstract:

A range selection system for a vehicle including an automatic transmission and an internal mode switch (IMS) assembly. The range selection system includes a housing that is rotatable around a core, a first set of switches that induce a first current based on a rotational position of the housing and a second set of switches that induce a second current based on a rotational position of the housing. A control module determines first and second voltages based on the first and second currents, respectively and determines a range of the automatic transmission based on the first and second voltages.

Assignee:

GM Global Technology Operations LLC

International Classification:

B60G 23/00

US Classification:

701 39

Abstract:

A solenoid control system for a vehicle comprises a primary controller, a failover controller, and a failover control module. The primary controller generates a first solenoid drive signal based upon a control signal. The failover controller selectively generates a second solenoid drive signal based upon the control signal. The failover control module receives an operating signal that indicates whether the primary controller is functioning properly and selects the second drive signal to drive a solenoid when the operating signal indicates that the primary controller is not functioning properly.
