車両用ヘッドアップディスプレイ装置
Document Type and Number:
Japanese Patent JP5093279
Kind Code:
B2
Abstract:
A head up display device for a vehicle includes a display; an optical system having a reflecting mirror; a stepping motor; and a control system having a determining device, a micro-step control device, and a forcible control device. The determining device determines whether an adjustment command for micro-step control is given. The micro-step control device performs the micro-step control as long as the determining device determines that the command for the micro-step control is given. The forcible control device forcibly controls a drive signal such that an electrical angle changes to a stabilizing point. When determination made by the determining device switches from determination that the command is given to determination that the command is not given, the forcible control device forcibly controls the drive signal, provided that the electrical angle as of the time of the determination that the command is not given is shifted from the stabilizing point.
