  • Automotive wiper control system with fail-safe feature for preventing burn-in of wiper motor
    Patent number: 5049794
    Abstract: A wiper control system includes measures an elapsed time of operation cycle, through which a wiper blade assembly performs one cycle of wiper operation. The wiper control system resets the measured elapsed time when ever the wiper blade assembly reaches a predetermined position. On the other hand, wiper control system detects the measured elapsed time exceeding a given period of time to initiate a predetermined fail-safe operation. In practice, the fail-safe operation is performed to intermittently drive the wiper motor with an interval which is long enough to sufficiently cooling off the wiper motor, when fail-safe operation is performed while wiper system is maintained ON, and to terminate driving of the wiper motor when the wiper system is turned OFF.
