    摘要： 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.

    摘要： A wiper control device in which an abnormal condition of a FET is detected by distinguishing an action of an overheat-cutting protective function normally difficult to be detected with measuring the drain voltage of the FET and by which the control of the pertinent FET is restrained upon the detection of abnormality so as to prevent a short circuit in the wiper control device from occurring. When an FETB (Qb) is set on, whether or not a drain voltage Vd is lower than Vpe ({fraction (l/2)}VG) is judged (step S5), and if lower, it is judged that the drain and ground is short-circuited, that is, an overheat-cutting protective function is acted, and “1” is added to the number of times of short circuit detection Perror (step S7). It is judged whether or not the added value of the number of times of short circuit detection Perror reaches a reference value (step S11). If the reference value is reached, it is judged that the drain and ground is actually short-circuited, that is, an overheat-cutting protective function is acted, and each action of a FETA (Qa) and FETB (Qb) is halted (step S13).

    摘要： A method and device for detecting an initial excitation phase of a stepping motor is provided, by which an initial excitation phase of a rotor corresponding to a position of a stopper can be detected with a unit of a stepping angle of a microstep drive which is smaller than that of a full step drive without using elements such as magnetoelectric elements. Upon appropriately changing an excitation phase of a stepping motor, on the basis of a generated pattern of an induced electromotive force in an exciting coil in a non-excitation state upon a full step drive, whether or not a pointer comes in contact with a stopper to stop a reverse rotation of the pointer and rotor is judged so that it is specified on which excitation phase the pointer and rotor are reversed, thereby detecting an initial excitation phase of the rotor corresponding to a position of the stopper.
