1.3.5. The onboard computer

The onboard computer analyzes and deduces on the display of value of a stock of a course on fuel, time in a way, the average expense of fuel, average speed, the fuel expense at present and the passed way.

The onboard computer analyzes and deduces on display FIS нижеперечисленные the data.

Fig. 1.51. Indication of the onboard computer the current expense of fuel

6 types of information (a course stock on fuel, time in ways, the average expense of fuel, average speed, the current expense of fuel and the passed way) are deduced on display FIS in the above-stated sequence (fig. 1.51).

All an indicator (the average expense of fuel and the current expense of fuel, a course stock on the fuel, the passed way both average speed and the fuel expense at present) are displayed in metric, and in certain export variants in English system of units.

The onboard computer is completed with two automatically working memories.

Fig. 1.52. A cell of memory 1

Indication of level of the memory included at present is deduced on the display in a kind инверсивного (negative) number. Occurrence on figure 1 display means a conclusion of the data of a single memory (a cell of memory 1) (fig. 1.52). Occurrence on figure 2 display means a conclusion of the data of the general memory (a cell of memory 2).

The single memory accumulates the information from the moment of inclusion of ignition till the moment of its deenergizing. At renewal of movement during 2 ч after ignition deenergizing to already saved up information new values are added. At a break of movement more than 2 ч there is an automatic dump of the data of a memory.

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

Management of the onboard computer is carried out by two switches mounted in the handle of management by a screen wiper.

Press the top or bottom party of the switch of functions And (fig. 1.53). There is a consecutive conclusion to the display of 6 functions of the onboard computer.

Fig. 1.53. Controls the onboard computer

Will choose actual function.

Press and keep a minimum one second the dump button (RESET) In (fig. 1.53).

The dump button it is possible to null following values:

– Time in a way;

– The average expense of fuel;

– Average speed of movement;

– The passed way.

The onboard computer works only at the included ignition. At ignition inclusion on the display last is deduced at the moment of deenergizing of ignition function. Short pressing of the switch of functions And or dump buttons In it is possible to disconnect also indication of a reminder on necessity of a break of movement

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

The given indication helps at planning.

On the display there is an indication of a stock of a course in kilometres. The given indication shows, how many kilometres the car still can pass on the actual rest of fuel in the given mode of movement. The course stock on fuel is defined by the discrete values counted by steps on 10 km.

The expense of fuel on the last is accepted to a basis of calculations of a stock of a course of 30 km of a way. At more economic subsequent movement the course stock increases.

Time indication in a way reminds of necessity of a break for movement.

On the display time in a way with readout from the moment of last dump of the data of memory of a memory is deduced. At desire to reckon time in a way since the certain moment, clear memory button "RESET" pressing.

If the movement break makes more than two hours there is an automatic dump of indication of time in a way.

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

In two hours after a start of motion, irrespective of the programmed function, there is an automatic switching on time display in a way. Blinking indication of a kind 2:00 reminds the driver of necessity to make a break in movement.

Short-term pressing the top or bottom party of the switch of functions or button "RESET" the given indication can be switched off.

At continuation of movement or if the break makes less than 10 mines in each next two hours the reminder on necessity will stop on rest to repeat with time indication in a kind way 4:00, 6:00 etc. At duration of a break more than 10 mines occur to the switched off ignition dump of the data of readout of time in a way.

The given indication helps at movement planning.

On the display display the average expense of fuel in litres on 100 km, calculated is deduced from the moment of last dump of the data of memory. By means of the given indication it is possible выберать the mode of movement corresponding to the optimum expense of fuel. At desire of definition of the average expense of fuel anew it is necessary to carry out dump of the data of memory by button "RESET" pressing. At journey of the first 30 m after dump on the display zero value is deduced.

If the movement break makes more than 2 ч there is an automatic dump of the data of the average expense of fuel.

At the switched off ignition value of the average expense of fuel remains in memory. At movement continuation the data of the subsequent expense is considered.

Fig. 1.54. Button "RESET" and the switch of functions

Button "RESET" and the switch of functions of the handle of a screen wiper it is possible to cause menu indication, to read out the data and to carry out adjustment (fig. 1.54).

Press button "RESET" so often, there will be no yet a menu indication.

For management of menu indication press the switch of functions. Switching (forward/back) is carried out similarly indications.

Press button "RESET".

Pressing of the switch of functions makes sample of indication of the menu / probably change of parametres of adjustment. The chosen parametres are allocated with a red background.

Button "RESET" pressing the chosen joins the established parametres funktsija/prove to be true. The chosen functions are marked with "tick".

Initial menu FIS gives the chance samples of 4 kinds of indication.

To four kinds of indication of the initial menu there correspond the functions listed more low.

– Uhr (hours).

– Computer (computer).

– Tempoalarm (Geschwindig-keitswarnung) (the alarm system of excess of speed).

– Reifendmckwarnung (the monitoring system of pressure of air in tyres).

– Radioanzeige (inclusion/deenergizing).

– Sprache (language).

– Einheiten (switching of units of measure of the passed way, the expense, time zone, temperatures).

– Service (maintenance service).

– Menu aus (menu deenergizing).

On the display there is a usual indication, as well as on cars without menu indication.
