DOOR MIRROR CONTROL DEVICE - KK TOKAI-RIKA-DENKI-SEISAKUSHO

Title:

DOOR MIRROR CONTROL DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/194903

Kind Code:

A1

Abstract:

The door mirror control device supplies drive voltages (VD) to lock detection circuits (24) for right and left door mirrors, respectively. The door mirrors move from either a closed position or an open position to the other position by being driven by motors (22) in response to the drive voltages (VD), and the motors (22) are stopped when the door mirrors have reached the closed position or the open position. An operating time determination part (48) determines operating times of the door mirrors from a change in the current values (ID) of operating currents. A voltage setting part (52) changes, on the basis of the operating times of the right and left door mirrors, the settings for the drive voltages (Vp) to be supplied to the lock detection circuits (24) for the door mirrors such that the operating times of the right and left door mirrors are matched with each other.
