International Classification:

B60K 4120

US Classification:

477 94

Abstract:

A shift control and shift strategy for an automatic transmission in an automotive vehicle driveline wherein the automatic ratio shift schedule can be disabled selectively to accommodate a manual ratio shift control. A driver-operated mode selection switch permits the operator to select normal automatic ratio control or a launch-assist mode during operation in the normal ratio shift mode. Ratio changes occur in response to driveline operating variables in a vehicle launch-assist mode. The transmission control system is commanded to effect a high speed ratio when the vehicle is stationary with the brakes applied. The operating mode defaults to a normal ratio shift mode as the operator releases the wheel brakes. In an alternative embodiment of the invention, the control includes multiple enable switches for achieving manual selection of the ratios when a manual upshift sequence is desired.

Abstract:

A position sensor having a magnetic proximity switch comprising relatively movable reeds (10, 12) having magnetic properties and a magnet (28) adapted to establish a magnetic flux field (18) that envelops the reeds (10, 12) to establish a magnetic attraction between the reeds, the strength of the magnetic flux field depending upon the spacing of the reeds with respect to the magnet, the magnetic attraction of the reeds being sufficient to cause them to move into electrical contact as the magnetic flux field in the vicinity of the reeds is changed in intensity as a magnetic shield (30) is moved through the flux field whereby the opening and the closing of a circuit defined by the reeds provides an indication of the position of the shield (30) with respect to the reeds (10, 12).

International Classification:

G01L 300

US Classification:

701 54

Abstract:

A method for determining the onset of positive torque through an automatic transmission (the power-on point), includes saving engine torque magnitudes within a specified tolerance of each other and within a adaptive limits, the highest torque value of the sampled torque magnitudes being stored in memory. The saved value plus a calibrated safety margin is used to compare to the calculated transmission input torque. If the input torque is higher, the powertrain is considered "power-on. " In addition to the safety margin, other calibratable adder torque values can be used to compensate for air conditioning, electrical loads, temperature, etc. If the samples fall below the lower adaptive limit, the lower limit is used plus any torque adders. If the adaptive samples are above the adaptive limit, the upper adaptive limit is used without any torque adders. A calibrated baseline torque value is used for power-on determination until enough valid samples are obtained.

International Classification:

B62D 504

US Classification:

180142

Abstract:

An electronic control system for a steering system having an electric motor coupled to the steering system for providing power assist. The steering system is of the rack and pinion type having an input gear coupled to the steering wheel and a pinion gear in meshing engagement with the rack. Two torsion sensors are coupled across the input and pinion gears and generate analog output signals. When no input torque is applied to the steering wheel, the output signals from the two torsion sensors are equal. When input torque is applied to the steering wheel, the signals from the torsion sensors vary substantially linearly in opposite directions. An electronic control unit controls operation of the electric power assist motor in accordance with the output signal from one of the torsion sensors. Failsafe circuitry is provided for monitoring the outputs of the redundant torsion sensors to insure proper control of the electric power assist motor. The failsafe circuitry provides (i) a sensor-to-sensor check to insure the output voltage of one sensor is consistent with the output voltage of the other sensor, (ii) a sensor limit check to insure that the output voltage from each sensor does not exceed a predetermined limit, (iii) a sensor direction check to insure that the signal being used to drive the electric power assist motor, as derived from one sensor, will drive the motor in the same direction sensed by the other sensor, and (iv) an excess assist check to insure that the signal used to drive the electric assist motor, as derived from one sensor, will not cause the motor to provide a greater amount of assist than an amount requested, as detected by the other sensor.

International Classification:

G01M 1500

US Classification:

701 62

Abstract:

A method and system for testing the functionality of a solenoid used to change the apply state of a torque converter clutch in a vehicle having an electronic control unit and a driveline system including an engine, a transmission, a torque converter. A first torque converter speed ratio is established. The commanded apply state of the torque converter clutch is determined, then a second torque converter speed ratio is calculated using engine speed and output shaft speed. The functionality of the torque converter clutch solenoid is established by determining whether the torque converter clutch solenoid has changed the applied state of the torque converter clutch by performing a comparison of the first and second torque converter speed ratios.

US Classification:

701 34

Abstract:

A method and apparatus are provided to determine a failure of an automatic transmission temperature sensor in an automobile. The apparatus detects a start-up of the vehicle. A sensor detects the transmission fluid temperature. The transmission fluid temperature at start-up is checked to see if the temperature is below a first predetermined temperature or above a second predetermined temperature. If the sensor does not detect a predetermined change in temperature during operation of the vehicle after it is determined the transmission fluid temperature at start-up is above the first predetermined or below the second predetermined temperature, the sensor has failed.
