TRIP COMPUTER INFORMATION DISPLAY
id092200022500
Outline
• The following functions have been added to the trip computer display.
-
― Estimated fuel consumption
― Current average
― Fuel consumption history (at every reset)
Function
• The trip computer displays information based on the resistance value of the fuel gauge sender unit and the traveled distance signal, fuel injection amount signal, and vehicle speed signal from the PCM.
Estimated fuel consumption
-
• The estimated fuel consumption is displayed graphically as the average fuel consumption value from engine start (ignition switch: ON) to the present.
-
― White line (broken line)
-
• Average fuel consumption every 5 min for the previous 60 min is displayed by the broken line.
-
― Green line (horizontal line)
-
• Average fuel consumption for 1 drive*1 is displayed using a horizontal line and the display is updated every 30 s.
*1 :From engine start (ignition switch: ON) to engine stop (ignition switch: OFF)
Current average
-
• The current average is displayed as the average fuel consumption from engine start (ignition switch: ON) to the present.
• The display of the current average is updated every 30 s.
Fuel consumption history (at every reset)
-
• Fuel consumption history is displayed in bar graph form as the average fuel consumption value for the previous 5 resets.
• Fuel consumption history is updated every time the average fuel consumption is reset.
• If the number of average fuel consumption resets is less than 5 times, the history to that point in time is displayed.
Construction
• The trip computer is displayed in multi information display (MID) display 2.
Operation
1. When the instrument cluster detects (1) that the ignition is switched ON, voltage is applied (2) to the fuel gauge sender unit.
2. The instrument cluster detects (3) the remaining fuel according to the voltage sent from the fuel gauge sender unit.
3. The instrument cluster receives (4) the traveled distance signal, fuel injection amount signal, and vehicle speed signal from the PCM via the CAN signal.
4. The instrument cluster calculates (5) values for each vehicle information based on the remaining fuel, traveled distance signal, and vehicle speed signal and sends the display request signal to the multi information display (MID) via the CAN signal.
5. When the multi information display (MID) receives the display request signal, the trip computer is displayed in the LCD.
6. When the multi information display (MID) detects (6) that a circuit is established by pressing the INFO switch, the screen display is changed (7).
