1.2.3. Onboard control system


Fig. 1.4. Onboard control system

The block of the onboard control system is shown in the figure 1.4.
1 – a signaling device of insufficient level of oil in an engine case. Lights up orange light if oil level in a case of the engine fell below a tag of "MIN" of the index. Before a dolivka of oil check whether there was no leak of oil because of loss of tightness of the lubrication system.
2 – a signaling device of insufficient level of the washing liquid in a windscreen washer tank. Lights up orange light if in a tank there were less than 1 l of the washing liquid.
3 – a signaling device of insufficient level of cooling liquid in a broad tank. Lights up orange light at lowering of the level of cooling liquid on the cold engine below an admissible limit. Before a dolivka of liquid check tightness of the cooling system.
4 – signaling device of open doors. Lights up red light at not closed car door.
5 – signaling device of malfunction of lamps of a stoplight or marker lights. Lights up red light, in case of malfunction of a lamp of a stoplight when pressing a pedal of a brake or any lamp of dimensional light at their inclusion.
6 – signaling device of wear of overlays of blocks of forward brakes. Lights up orange light when pressing a pedal of a brake and burns before switching off of ignition if thickness of overlays of blocks of forward brakes decreased to 1,5 mm.
7 – a signaling device of not fastened seat belts. Lights up red light if seat belts of the driver are not fastened.
Functional modes of the block:
– it is switched off;
– waiting mode;
– preexit control of signaling devices;
– control of parameters.
The block is in the mode "Is switched off" until the key is inserted into the ignition switch. In situation 0 It ("is switched off") a key in the ignition switch the block passes into "Waiting mode". If at the same time the driver's door is open, there will be a malfunction "The forgotten key in the ignition switch" and the sound signaling device of the block during 5–7 with will give a faltering signal. The signal can be interrupted either having closed a door, or having taken out a key, or having turned a key in the ignition switch in situation I ("Ignition"). In the provision I of a key in the ignition switch the block passes into the Preexit Control of Signalling Devices mode at which for check of their serviceability on 3–5 with all join light and sound signaling devices, and then through a pause in 1 about the block passes into the Control of Parameters mode and with malfunction makes the alarm system on the following algorithm:
– the light signaling device of that parameter which went beyond norm begins to blink during 5–7 with then passes into the mode of a constant luminescence before elimination of malfunction or return of a key in the ignition switch in situation 0 ("Is switched off");
– at the same time with a light signaling device on 3 with the sound signaling device joins;
– if at the same time there is other malfunction, then the sound alarm system and light in the mode of a blinking begin to work for the last malfunction as more priority, and the light signaling device of the previous malfunction passes into the mode of a constant luminescence.
