1.3.5. On-board computer

The on-board computer analyzes and brings to the display of value of a stock of the course on fuel, time in way, average fuel consumption, average speed, fuel consumption at present and the passable way.
The on-board computer analyzes and brings following data to the FIS display.

Fig. 1.51. Indication of the current fuel consumption on-board computer


6 types of information (a course stock on fuel, time in way, average fuel consumption, average speed, the current fuel consumption and the passable way) are brought to the FIS display in the above-stated sequence (fig. 1.51).
All an indicator (average fuel consumption and the current fuel consumption, a course stock on fuel, the passable way and average speed and fuel consumption at present) are displayed in metric, and in certain export options in the English system of units.

Memory device
The on-board computer is completed with two automatically working memory devices.

Fig. 1.52. Cell of memory 1


Indication of level of the memory device which is switched on at present is brought to the display in the form of inverse (negative) number. Emergence on the display of figure 1 means a conclusion of data of the single memory device (a cell of memory 1) (fig. 1.52). Emergence on the display of figure 2 means a conclusion of data of the general memory device (a cell of memory 2).

Single memory device
The single memory device accumulates information from the moment of inclusion of ignition until its switching off. At renewal of the movement during 2 h after switching off of ignition new values are added to already saved up information. At a break of the movement more than 2 h there is an automatic dumping of data of the memory device.

General memory device
Automatic dumping of data of memory of the general memory device is impossible. It differs in it from the single memory device. Thanks to it it is possible to establish a time interval of the analysis of information or data.

Control of the on-board computer
Control of the on-board computer is exercised of two switches mounted in the handle of management of a screen wiper.

Selection of functions
Press the top or lower party of the switch of functions A (fig. 1.53). There is a consecutive conclusion to the display of 6 functions of the on-board computer.

Fig. 1.53. Governing bodies of the on-board computer



Installation of zero values
You will choose urgent function.
Press and hold at least one second the button of dumping ("RESET") B (fig. 1.53).
The button of dumping it is possible to nullify the following values:
– time in way;
– average fuel consumption;
– average speed of the movement;
– the passable way.
The on-board computer works only at the included ignition. At inclusion of ignition the last is brought to the display at the time of switching off of ignition function. Short pressing of the switch of functions A or buttons of dumping In it is possible to turn off also indication of a reminder on need of a break of the movement

NOTE
At a detachment of plugs of the accumulator all saved-up values are erased.

Course stock on fuel
This indication helps when planning.
On the display indication of a stock of the course in kilometers appears. This indication shows how many kilometers the car still can pass on the actual rest of fuel in this mode of the movement. The course stock is determined by fuel by the discrete values counted by steps on 10 km.
Calculations of a stock of the course fuel consumption on the last 30 km of a way is assumed as a basis. At more economic subsequent movement the stock of the course increases.

Time in way
Indication of time in way reminds of need of a break for the movement.
Time in way with counting from the moment of the last dumping of data of memory of the memory device is brought to the display. At desire to reckon time in way from a certain moment, clear memory pressing of the RESET button.

Single memory device
If the break of the movement makes more than two hours, then there is an automatic dumping of indication of time into ways.

General memory device
Value of time in way remains at the switched-off ignition. At continuation of the movement the subsequent time of the movement is added to it.

Reminder on need of a break for the movement
In two hours after a start of motion, irrespective of the programmed function, there is an automatic switching to time display in way. The blinking indication of a look 2:00 reminds the driver of need to take a break in the movement.
Short-term pressing the top or lower party of the switch of functions or the RESET button this indication can be switched off.
At continuation of the movement or if the break makes less than 10 min., then in each next two hours the reminder on need to stop for rest will repeat with indication of time in a way of a look 4:00, 6:00, etc. Lasting break more than 10 min. to the switched-off ignition there is a dumping of data of counting of time into ways.

Average fuel consumption
This indication helps when planning the movement.
The average fuel consumption in liters on 100 km calculated from the moment of the last dumping of data of memory is brought to the display of the display. By means of this indication it is possible to choose the mode of the movement corresponding to optimum fuel consumption. At desire of determination of average fuel consumption anew it is necessary to carry out dumping of data of memory pressing of the RESET button. At journey of the first 30 m after dumping zero value is brought to the display.

Single memory device
If the break of the movement makes more than 2 h, then there is an automatic dumping of data of average fuel consumption.

General memory device
At the switched-off ignition value of average fuel consumption remains in memory. At continuation of the movement data of the subsequent expense are considered.
