    • 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.
    • 一种用于车辆的抬头显示装置包括显示器; 具有反射镜的光学系统; 步进电机; 以及具有判定装置,微步控制装置和强制控制装置的控制系统。 确定装置确定是否给出用于微步控制的调整命令。 只要确定装置确定了给出微步控制的命令,微步控制装置执行微步控制。 强制控制装置强制地控制驱动信号,使得电角度变为稳定点。 当判定装置作出的判定从判断为切换到判断为没有给出指令时,强制控制装置强制地控制驱动信号,前提是该命令为确定时刻的电角度 没有给定从稳定点转移。
