PROBLEM TO BE SOLVED: To provide a vehicular seat device capable of reducing the wiring number of a harness to be connected to an ECU, and correctly detecting the position of a driving unit. SOLUTION: The vehicular seat device comprises a driving motor 31 for driving a movable unit, an ECU 10 for performing the operational control of the driving motor 31, and a harness h for supplying the driving current to the driving motor 31 from the ECU 10. The ECU 10 has a spike noise extraction circuit 13 for extracting the spike noise to be output to a supply wiring of the driving current from the driving motor 31 as the driving motor 31 is driven. A microcomputer 11 counts the number of rotation of the driving motor 31 based on the output signal of the spike noise extraction circuit 13. COPYRIGHT: (C)2010,JPO&INPIT |
