Abstract

Instantaneous state of a driver and instantaneous state of an automotive vehicle are identified based on sensed information related to the vehicle. Based on the identified instantaneous states in combination or in singular, one of predetermined indication modes is selected and pieces of information specified by the selected indication mode is displayed on a screen of a display unit.

Claims

1. A display system for use with an automotive vehicle, comprising:

a display unit having a predetermined area;

sensor means for sensing information related to the automotive vehicle; and

a control unit operatively connected to said sensor means and said display unit,

the control unit having stored therein a plurality of predetermined indication modes which specify different combinations of scales on which all indicators are displayed within said predetermined area, respectively,

the control unit being operative to select based on the sensed information such one of the plurality of predetermined indication modes in which only those indicators which the driver needs or should recognize are displayed in relatively larger scale; and

the control unit being operative to cause the display to display all of the indicators in accordance with what is specified by the selected indication mode.

2. A display system for use with an automotive vehicle, comprising:

a display unit having a predetermined area;

sensor means for sensing information related to the automotive vehicle; and

a control unit operatively connected to said sensor means and said display unit,

the control unit being operative to select one of a plurality of predetermined situations in which the driver of the automotive vehicle is involved based on the sensed information

the control unit having stored therein a plurality of predetermined indication modes which specify different combinations of scales on which all indicators are displayed within said predetermined area, respectively,

the plurality of predetermined indication modes corresponding to the plurality of predetermined situations in which the driver of the automotive vehicle may be involved such that if one of the plurality of predetermined situations is selected, only those indicators which the driver needs or should recognize in the one selected situation are displayed on larger scale than the other indicators in the corresponding one of the plurality of predetermined indication modes, and

the control unit being operative to cause the display to display all of the indicators in accordance with what is specified by the corresponding indication mode to the selected situation in which the driver is involved.

3. A display system as claimed in claim 2, wherein the plurality of predetermined indication modes specify a single scale on which a vehicle speed indicator is displayed.

4. A display system as claimed in claim 3, wherein the control unit is operative to lighten indicators intermittently upon a change from the selected indication mode for a new one.

5. A display system as claimed in claim 2, wherein the control unit is operative to lighten indicators intermittently upon a change from the selected indication mode to a new one.

6. A display system as claimed in claim 2, further comprising means for manually setting at least one of the plurality of predetermined indication modes to be selected.

7. A method of controlling a display unit for an automotive vehicle, the method comprising the steps of:

sensing information related to the automotive vehicle;

selecting one of a plurality of predetermined situations in which the driver of the automotive vehicle is involved based on the sensed information;

providing a plurality of predetermined indication modes which specify different combinations of scales on which all indicators are displayed within said predetermined area, respectively,

the plurality of predetermined indication modes corresponding to the plurality of predetermined situations in which the driver of the automotive vehicle may be involved such that if one of the plurality of predetermined situations is selected, only those indicators which the driver needs or should recognize in the one selected situation are displayed on larger scale than the other indicators in the corresponding one of the plurality of predetermined indication modes; and

displaying all of the indicators within a predetermined area on the display unit in accordance with what is specified by the corresponding indication mode to the selected situation in which the driver is involved.

8. A method as claimed in claim 7, wherein the plurality of predetermined indication modes specify a single scale on which a vehicle speed indicator is displayed.

9. A method as claimed in claim 8, further comprising the step of lightening indicators intermittently upon a change from the selected indication mode to a new one.

10. A method as claimed in claim 7, further comprising the step of lightening indicators intermittently upon a change from the selected indication mode to a new one.

11. A method as claimed in claim 7, further comprising the step of manually setting at least one of the plurality of predetermined indication modes to be selected.
