摘要： 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.

摘要： A head up display device includes a display, an optical system having a reflecting mirror, a motor, and a reduction gear mechanism having gears in engagement with each other. A stopper gear is further on a preceding side than the last gear in the mechanism. The stopper gear includes a partial gear portion having teeth arranged in a region of the stopper gear in a range of less than 360 degrees in its rotational direction. Rotation of the stopper gear is stopped by engagement of both-end teeth of the partial gear portion with a stopper-adjacent gear, so a range of a rotation angle of the mirror is limited to a predetermined adjustable range, which includes a displayable range. The angle between an adjustable range lower limit and displayable range lower limit, and the angle between an adjustable range upper limit and displayable range upper limit are larger than 0 degree.

摘要： According to a method for initializing an indicating instrument for a vehicle, zero-reset processing is performed. In the zero-reset processing, a control device is made to control a drive signal to rotate a pointer in a zero-reset direction in order to force a step motor to lose synchronization. Furthermore, synchronization loss detection processing is performed. In the detection processing, a physical phenomenon generated in a rotary drive system due to forcible synchronization loss of the motor during the zero-reset processing, is detected. Then, an electrical angle of the drive signal at a time of detection of the phenomenon is selected as a synchronization loss electrical angle. Finally, zero point setting processing is performed. In the setting processing, the electrical angle phase-shifted from the synchronization loss electrical angle in an indication value increasing direction by 180 degrees or less, is set as a zero point stored in the control device.

摘要： An indicating instrument for a vehicle includes a step motor including a field winding, a pointer, a stopper device for stopping the pointer, which is rotating in a zero-reset direction, at a stopper position, a detecting device for detecting induced voltage of the field winding at each of detecting points, a control device for performing zero-reset control, whereby a drive signal is controlled to rotate the pointer in the zero-reset direction. In a state of abnormal detection in which the induced voltage larger than a predetermined set value is detected at a zero point; and the induced voltage equal to or smaller than the set value is detected at a next detecting point to the zero point, the control device assumes synchronization loss of the step motor and continues the zero-reset control until an assumptive electrical angle corresponding to a rotational position of the pointer reaches the zero point.

摘要： A circuit board is divided into two portions: a flexible printed circuit board; and a printed circuit board. On the flexible circuit board, movements whose layouts on the flexible circuit board are changed based on a design change in a dial plate due to a model change in a vehicle, light emitting diodes, a connector, a buzzer, and a changing-over switch are mounted. On the printed circuit board, a controller that radiates electrical noise during its operation is mounted. This enables a countermeasure for radiating of the electrical noise from the controller to be completed within the printed circuit board. This also enables a circuit design of the flexible printed circuit board to be easily performed. Man power for designing a combination meter can be thereby decreased; further, the combination meter capable of restricting generation of the electrical noise is achieved.

The rotor has a first end face and a second end face in an axial direction of the rotor. The first end face and the second end face are separated from the first wall and the second wall, respectively. A lubricant fills between the through hole and the supporting shaft, and an oil repellent agent is applied at a predetermined first area of the first wall around the supporting shaft and a predetermined second area of the second wall around the supporting shaft.
