Abstract: A mounting structure and methodology for mounting audio speakers in the package shelf of a motor vehicle. The speakers are mounted in a well formed integrally with the package shelf. The well opens at its upper end in the package shelf and defines an annular ledge at its lower end sized to seat the annular flange of the speaker. Resilient spring fingers on the annular wall of the well flex outwardly in response to insertion of the speaker into the well to allow passage of the speaker flange and thereafter, upon seating of the speaker flange on the ledge, flex inwardly to lockingly clamp the speaker flange between the spring fingers and the ledge. A grille structure includes a grille sized to fill the opening in the package shelf and a plurality of fingers extending downwardly from the grille and sized to fit within the well structure.

Abstract: This invention provides automatic and reliable determination of the touch point of a clutch controlled by an automatic clutch actuation controller. This invention determines the touch point upon power-up while idling the engine, with the transmission in neutral and an input shaft brake applied. The clutch actuation controller gradually engages the clutch so that the measured transmission input speed matches a reference speed signal preferably between 40 and 60% of the idle speed. If the actuation is slow enough, this reliably provides the degree of clutch engagement at a small torque matching the braking torque which is the touch point. If there is no previous knowledge of the touch point, the clutch is applied at a fast rate and an approximate touch point is determined, then the clutch is positioned below the approximate touch point and is again applied at a slow rate to more accurately ascertain the touch point.
