  • Patent number: 6982868
    Abstract: A display device for a motor vehicle. In order to allow a compact, space-saving and cost-effective design and a rotation of the display with little change in position, the display device includes a display housing for mounting on a vehicle dashboard; and a display frame for accommodating a display. The display is rotatable with respect to the display housing. The display device further includes a driven element affixed on the display housing; and a drive device affixed on the display frame, having an electric motor, a worm gear and a gear-output shaft for engaging with the driven element. The electric motor arranged in a center region of the display frame and the engagement of the gear-output shaft with the driven element occurs outside the axis of rotation.

  • Patent number: 6032608
    Abstract: A pointer device having an illuminated pointer made of light-guiding material, mounted rotatably about a pointer axis, having a permanently mounted light source whose light is coupled axially into the illuminated pointer. The illuminated pointer includes a radial section which constitutes a pointer vane, and an axial section which constitutes a light gatherer. Light deflection from the axial section to the radial section takes place via a reflective surface and a first-surface mirror.

  • Patent number: 5942872
    Abstract: A method and a device for controlling a stepping motor in which the width of step and the direction of rotation of the stepping motor are determined in a controller and sent to a control arrangement for controlling the stepping motor. Upon each step clock signal from the controller, a step is carried out. The step width output by the controller is divided by the control circuit into a plurality of smaller partial steps the step width of which is smaller than the step width output by the controller, and these partial steps are sent in several time-staggered pulses by the control circuit to the stepping motor.

  • Patent number: 5847475
    Abstract: The invention describes a method that makes it possible to correct a nonlinear relationship between the electrical phase angle and the mechanical output angle of stepper motors, using a low-resolution encoder or the like. The method of the invention makes a compromise between the conventional closed-loop control of stepper motors, which requires high resolution of angular detection, and a purely static correction of the characteristic curve. The result is a substantial improvement in synchronization, for instance when conventional claw pole stepper motors are used, as a pointer drive for a gauge in a motor vehicle. The microstep triggering is done with a corrected sinusoidal form; for the correction, coefficients that are evaluated by means of a simplified Fourier synthesis are essentially used.

  • Patent number: 5847531
    Abstract: A process for reducing the strength of an uncontrolled movement of a pointer driven by a stepper motor and abutting against a mechanical stop means when the stepper motor is switched off. Prior to the switch-off operation, the field strength of the magnetic field of the stepper motor is lowered, or the pointer is moved away from the stop means by a specified compensating angle of rotation. Alternatively, following the switch-off operation, the stepper motor is switched on again at least one time following a specified time span for a specified switch-on time span.
