Document Type and Number:
Japanese Patent JP2813184
Kind Code:
B2
Abstract:
The invention is directed to an arrangement for adjusting an operating characteristic quantity of an internal combustion engine such as for the idle speed control with a redundant drive. Two windings of the drive are driven via two separate lines from two separate output stages. When a defect is detected via an electrical monitoring unit, a safety logic unit transfers the full operation for the drive of the throttle flap to the output stage and the winding corresponding thereto which are not affected by the defect. In this way, a noraml idle speed of the engine is assured even in the presence of a single defect.
