Drive control appts for electrically driven door of motor vehicle

摘要

The appts includes a DC motor (M) that moves the electrically driven doors of a motor vehicle. A detector detects a terminal voltage due to an EMF induced in the DC motor when the door is moved manually. The direction of rotation of DC motor due to induced EMF is judged based on the detection results. A microcomputer (1) drives the DC motor in a predetermined direction based on the judgment results.
