Abstract
A function selecting control system is provided, which modularizes a plurality of wiper control systems, builds them in an integrated circuit, and selects a desired system on the basis of a selection signal of the system from the outside, thereby drive-controlling a wiper motor. The function selecting control system includes: input device 30a for inputting a selection signal which selects a control logic block 30h corresponding to a starting control mode out of the control logic blocks provided for every control mode of the motor; judgment device 30c for reading the input selection signal for a standard number of times and for judging the coincidence among the read selection signals; count device 30e for counting the number of times of the coincidence; settlement device 30f for settling the selection signal when the number of times of the coincidence reaches the predetermined standard number; and system starting device 30g for starting a control logic corresponding to the settled selection signal.
