A window wiper feedback pattern is disposed on a stationary circuit board mounted within a gear enclosure with its electronic components facing inwardly toward a main gear. A low profile, flip chip integrated circuit attachment to the printed circuit board is also provided.
The invention claimed is: 1. A system for use in an automotive vehicle, said system comprising:an electric motor; a gear enclosure; a gear located in said gear enclosure and operably rotating in response to energization of said electric motor; a circuit board located in said gear enclosure; a microprocessor mounted to said circuit board in a flip chip manner, said microprocessor controlling energization of said electric motor; and a shaft rotatably driven by said gear. 2. The system of claim 1 wherein said microprocessor acts as a multiplexing node.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An automotive vehicle, such as a minivan or the like, has a rear liftgate door which can pivot about an upper pair of hinges coupled to the vehicle body structure. When the liftgate is pivoted to an open position, a cargo space is accessible from behind the vehicle. Such a liftgate is shown in FIG. 1. Liftgate 31 has a rear window or back light 33 pivotable between a closed position, substantially flush with the outer surface of liftgate 31, to an open position about the upper hinges. A pair of pneumatic cylinders 35 act to push window 33 toward the open position when a lower portion of window 33 is released. A multi-functional window wiper motor system 41 of the present invention is mounted upon an inner surface of liftgate 31 and is operated by the preferred embodiment of a control system of the present invention. The majority of system 41 is hidden by an interior trim panel (not shown). System 41 includes a central drive and power transmission unit 43, a window wiper assembly 45, a window release latch or lock 47 and a liftgate lock 49, all of which are mounted upon liftgate 31. Examples of such locks (employing separate solenoids or motors, which would be removed in order to couple the lock mechanism for use with the present invention) are disclosed within the following U.S. patents: U.S. Pat. No. 5,222,775 entitled "Power Operated Latch Device for Automotive Back Door" which issued to Kato on Jun. 29, 1993; U.S. Pat. No. 4,422,522 entitled "Inertial Lock for Vehicle Door Latch" which issued to Slavin et al. on Dec. 27, 1983; and, U.S. Pat. No. 3,917,330 entitled "Electric Lock Release" which issued to Quantz on Nov. 4, 1975; all of which are incorporated by reference herewithin.
Feedback pattern 231 has an annular rounded shorting ring 233, also denoted as POS 4, a first arcuate trace 235, also denoted as POS 1, a second arcuate trace 237, also denoted as POS 2, third and fourth arcuate traces 239, 241, also denoted as POS 3, and an interval position ring 243, also denoted as POS 5. A set of radially extending conductive tics 245 are coupled together by a circular conductive trace 247 for interval position ring 243. Tics 245 are equally spaced from each other and are disposed entirely around 360 absolute on/off signals indicative of whether main gear 55 (see FIG. 2) is within a predetermined window wiping, door lock actuating, window lock release or dwell positional ranges. However, tics 245 provide incremental signals indicative of the exact location of main gear 55, as well as the devices driven therefrom, such as the window wiper, door lock, window release device or intermittent motion mechanisms, within each positional range.
Referring now to FIGS. 5, 6, 8 and 9, fourteen 90 mounted on terminal pads 225 of circuit board 201 for mating with a body wire harness. Terminals 301 are preferably stamped from a phosphor-bronze metal alloy which can be obtained from Autosplice Co.; terminals 301 have a flat blade configuration. Terminals 1 through 7 have double leg fastening to circuit board 201 while terminals 8 through 14 have single leg fastening. First, blind holes are drilled in gear cover 203. Next, the holes are filled with non-conductive material to prevent the subsequently inserted terminals from shorting against gear cover 203. Third, circuit board 201 is laminated to gear cover 203, and then terminal holes are drilled in circuit board 201 and the filler material. Finally, the terminals are mounted to circuit board 201. However, surface mounting of the terminals to eliminate drilling and filling of the gear cover prior to laminating would be preferred.
The solid line 501 indicates a wet glass condition, the faster speed dashed line 503 indicates a dry glass condition while the lower speed dashed line 505 is indicative of a degraded system condition over time. Such a lifetime degradation can be caused by a lack of lubrication or failure of bearings within the motor. The profiles of FIG. 19 are employed to sense the wiper performance on a real time, automatic and continuous basis. The automatic interval selection can be based upon the change in wipe time from dry conditions (t.sub.3 -t.sub.1) or wet conditions (t.sub.2 -t.sub.1). If t.sub.dry =t.sub.3-t.sub.1, and t.sub.wet =t.sub.2 -t.sub.1, then t.sub.wet &lt;t.sub.wipe &lt;t.sub.dry (bounded t.sub.wipe), and t.sub..sub.interval =f(t.sub.wip) (where the interval is a function of t.sub.wipe).
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a front elevational view showing the preferred embodiment of a window wiper motor system for an automotive vehicle of the present invention;
BACKGROUND OF THE INVENTION This invention relates generally to window wipers and specifically to a window wiper motor system for an automotive vehicle.
