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.
Claims8
A control method for switching between scales in a vehicular instrument that includes a dial which has a display section capable of displaying a plurality of scales at a front face side thereof, a light source which controls the display section to emit light for displaying, a pointer which turns to indicate a value associated with an arbitrary scale on the display section, and a light source which controls the pointer to emit light for displaying, the vehicular instrument switching emission of light for displaying between the plurality of the scales respectively and rotating the pointer for indication, thereby displaying a plurality of pieces of vehicle information on the identical display section, the control method comprising:
- a light emission stopping step of stopping emission of light for displaying a scale associated with a first vehicle information display when a display on the dial is changed from the first vehicle information display to a second vehicle information display;
- and
- a light emission starting step of starting emission of light for displaying a scale associated with the second vehicle information display.
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,
- wherein the vehicular instrument 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 is stopped, and after that, emission of light for displaying a scale associated with the second vehicle information display is started.
