摘要： PROBLEM TO BE SOLVED: To readily recovers a relay drive circuit to an output operation state after a short circuit is cancelled while preventing the relay drive circuit from being damaged by the short circuit. SOLUTION: In the short circuit protection circuit, an ECU 1 has the relay drive circuit 11 which outputs a drive current to a relay 2 in accordance with an input relay drive signal A, and a short circuit detection circuit 12. The short circuit detection circuit detects the occurrence of the short circuit at an output side of the relay drive circuit 11 and suspends output operation of the relay drive circuit 11 when the short circuit occurs. Further, the short circuit detection circuit intermittently transmits a recovery signal to the relay drive circuit 11 in a certain time interval after a predetermined time elapses from when the short circuit occurs to recover the output operation of the relay drive circuit. The time interval is gradually increased as time passes, so that the time ratio of the time between a time when the short circuit is resolved, and a time when the output operation of the relay drive circuit 11 is restored, becomes ≤10%, for the time when the short circuit occurred.

摘要： PROBLEM TO BE SOLVED: To provide an electronic throttle control device for an internal combustion engine which can precisely detect a fully closed position of a throttle valve which is directly opened and closed by a motor. SOLUTION: If such a condition that a drive current running through a motor 15 becomes sufficiently high is continued, it is regarded that a gear 18a at a final stage in a reduction gear unit 18 for a throttle valve 14 abuts against a stopper 19, and accordingly, the drive current is reduced so as to decrease the drive torque of the motor 15. Thus, after strains are removed from the final stage gear 18a of the reduction gear unit 18, and the shaft of the throttle valve 14, a fully closed position of the throttle valve 14 is learned. Accordingly, it is possible to precisely learn the fully closed position.

摘要： PROBLEM TO BE SOLVED: To speedily recover an output operation state without damaging a relay drive output circuit after short-circuiting that occurs in the circuit is canceled.SOLUTION: An ECU 1 comprises a relay drive output circuit 11 and a short-circuit detection circuit 12. The relay drive output circuit 11 outputs a drive current to a relay 2 on the basis of an inputted relay drive signal A. The short-circuit detection circuit 12 detects whether short-circuiting occurs at an output side of the circuit 11, stops an output operation of the relay drive output circuit 11 in the case where the short-circuiting occurs and, on the other hand, transmits a recovery signal to the relay drive output circuit 11 at a certain time interval, after the lapse of a predetermined time from the occurrence of short-circuiting, to recover the output operation. The time interval is gradually increased in accordance with the lapse of time in such a manner that a time ratio of a time between the time when short-circuiting is canceled and the time when the output operation of the relay drive output circuit 11 is recovered, with respect to the time during which short circuiting occurs, becomes 10% or less.
