A controller for controlling a wiper unit (1) including a wiper and an intermittent wipe cycle setting device (3) for setting an intermittent wipe cycle of the wiper. The cycle setting device (3) is set at a plurality of positions respectively corresponding to different intermittent wipe cycles. Further, the cycle setting device (3) has a resistance value (8), 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 (R8) of the intermittent wipe cycle setting device from the output signal by using a learned value (R7). 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. |
