  • Torque sensor assembly for a motor vehicle and method of measuring torque
    Patent number: 9146167
    Abstract: A torque sensor assembly is used to measure torque in a powertrain of a motor vehicle, the powertrain including a power source and a transmission. A sensor is coupled to an oil seal housing, which is coupled to the engine. Each of the sensor and the oil seal housing has a mounting hole formed therein. The sensor is coupled to the oil seal housing, and the oil seal housing to the engine, by inserting one fastener into both mounting holes. The sensor measures an amount of torque exerted on a drive plate of the transmission. The drive plate includes a central disk, made of a magnetizable material, and an outer ring coupled to the central disk. The sensor is a magnetic torque sensor, which determines an amount of torque exerted on the central disk of the drive plate by sensing a magnetic flux passing through the drive plate.

  • Multiple-ratio automatic transmission control method and system for ratio upshifts
    Patent number: 8529406
    Abstract: A speed ratio shaft control for multiple ratio vehicle transmission has controlled release of an off-going transmission clutch and controlled engagement of an on-coming transmission clutch during a speed ratio upshift, at least one clutch being a friction torque establishing clutch. A controller, using shift-timing software strategy, actively manages in real time a clutch torque level for each clutch so that transient torque disturbances in a transmission torque output shaft are mitigated.
