Drive circuit for a wiper device |
摘要 |
A drive circuit for a wiper device includes reversible driving motors for alternately driving a pair of wiper assemblies in first and second directions. Each driving circuit includes a switching means and a means for detecting both ends of the wiper blade motions in the first and second directions. The switching means is operative to switch the direction of electric current supplied to an electric motor when the detecting means detects the end of wiper blade motion. Each driving circuit is connected to both of switching means so that it can reverse the current supplied to the driving motor when both of switching means detect the ends of the wiper assembly motion.
