  • Wiper unit controller and method for controlling wiper unit
    Patent number: 7622878
    Abstract: A wiper unit controller for performing wiping at an accurate intermittent wipe cycle. The controller stores a maximum resistance value of a variable resistor having a resistance value that varies in accordance with the intermittent wipe cycle. When a reference time elapses after calculating a resistance value that exceeds the stored maximum resistance value, a computer renews the maximum resistance value with a new maximum resistance value.
    Type: Grant

  • Wiper controller and method for controlling wiper
    Patent number: 7504798
    Abstract: A controller for controlling a wiper unit including a wiper and an intermittent wipe cycle setting device for setting an intermittent wipe cycle of the wiper. The cycle setting device is set at a plurality of positions respectively corresponding to different intermittent wipe cycles. Further, the cycle setting device has a resistance value, which changes in accordance with each of the positions, and generates an output signal, which is in accordance with the change in the resistance value. The controller computes position information of the intermittent wipe cycle setting device from the output signal by using a learned value. The computer adjusts the learned value in accordance with the computation result of the position information to correct the position information. Accordingly, resistance value variances of the intermittent wipe cycle setting device are automatically corrected.
