摘要： When an operation of lowering window glass is conducted to attain a full-opened state and a lock current flows, a lowering operation is invalidated, thereby preventing the lock current from continuously flowing. When a raising operation is conducted under the full-opened state, a power window motor is operated in a direction of closing the window glass, and the in validating state is canceled. In the case where, before the full-closed state is attained, a foreign object is caught and the lock current flows, the same as above is conducted. In a raising operation of closing the window glass, the raising operation under the full-closed state is invalidated, thereby preventing the lock current from continuously flowing. When a lowering operation is conducted under the full-closed state, the power window motor is operated in the direction of opening the window glass, and the invalidating state is canceled.

摘要： A wiper control device is provided, 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 an accident in the wiper control device from occurring. When a FETB (Qb) is set on, whether or not a drain voltage Vd is lower than Vpe (nullVG) 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 null1null is added to the number of times of accident detection Perror (step S7). It is judged whether or not the added value of the number of times of accident detection Perror reaches a reference value (step S11). If reaches, 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).
