Abstract
A purpose of the invention is to provide a control method for switching between scales in the vehicular instrument that can prevent erroneous recognition and perform highly safety displaying. When a vehicle information display of a scale A is changed to a vehicle information display of a scale B, emission of light for displaying a scale associated with the vehicle information display of the scale A is temporarily stopped, and after that, emission of light for displaying a scale associated with the vehicle information display of the scale B is started.
Claims3
A vehicular instrument, comprising:
- a dial that has a display section capable of displaying a plurality of scales at a front face side thereof;
- a light source that controls the display section to emit light for displaying;
- a pointer that turns to indicate a value associated with an arbitrary scale on the display section;
- and
- a light source that controls the pointer to emit light for displaying,
- a controller that switches an emission of light for displaying between the plurality of the scales respectively and rotates the pointer for indicating, thereby displaying a plurality of pieces of vehicle information on the identical display section;
- and
- wherein when a display on the dial is changed from a first vehicle information display to a second vehicle information display, emission of light for displaying a scale associated with the first vehicle information display and for illuminating the pointer are turned off, thereafter, emission of light for displaying a scale associated with the second vehicle information display is turned on, and thereafter the pointer in a non-illuminated state is rotated to a predetermined position corresponding to the scale associated with the second vehicle information display, and illumination of the pointer located at the predetermined position is turned on.

- and
- wherein when a display on the dial is changed from a first vehicle information display to a second vehicle information display, emission of light for displaying a scale associated with the first vehicle information display is turned off, and the pointer in an illuminated state is rotated toward a predetermined position corresponding to the scale associated with the second vehicle information display, and thereafter, emission of light for displaying a scale associated with the second vehicle information display is turned on.

- and
- wherein when a display on the dial is changed from a first vehicle information display to a second vehicle information display, the illumination of the pointer associated with the first vehicle information display is turned off to a non-illuminated state, thereafter, emission of light for displaying a scale associated with the first vehicle information display is gradually decreased and turned off, thereafter, emission of light for displaying a scale associated with the second vehicle information display is gradually increased thereby turning on the illumination of the scale associated with the second vehicle information display, thereafter, the pointer in the non-illuminated state is rotated to a predetermined position corresponding to the scale associated with the second vehicle information display, and thereafter, the illumination of the pointer is turned on at the predetermined position corresponding to the scale associated with the second vehicle information display.
