Title:
電動アクチュエータシステム、及び車両用空調装置。
Document Type and Number:
Japanese Patent JP4356447
Kind Code:
B2
Abstract:
In a vehicle air conditioner with an electrical actuator system, a transmission mechanism transmits a rotation force of an electrical motor to an air mixing door when first and second pulse signals are generated from first and second brushes in a door operation region of a pattern plate. In contrast, the transmission mechanism stops the transmission of the rotation force to the air mixing door, when the first and second pulse signals are generated in the first and second brushes in an initialization region. Therefore, in the initialization region, the detection position of the air mixing door is the same regardless of a rotation direction of the electrical motor. As a result, even when the initialization region is arranged at a middle position in the door operation region, the rotation position of the air mixing door can be accurately detected.
