Cars are equipped with the following systems:

– regulations of speed which allows to support the speed chosen by the driver. This function can be turned off at any time pressing a pedal of a brake or one of system switches.

– restrictions of speed which allows the driver to establish speed limit. At excess its impact on a pedal of an accelerator does not lead to increase in speed of the car. The chosen speed can be increased at any time pressing an accelerator pedal with transition through resistance point.

Fig. 7.92. Flowchart of system of regulation and restriction of speed: 1 – switch (regulator) of the limiter of speed; 2 – switches on a steering wheel; 3 – accelerator pedal; 4 – guard of devices; 5 – the coupling course sensor (if it is established); 6 – stoplight switch; 7 – the central electronic switching block in salon; 8 – EBU ABS; 9 – EBU of system of injection

Management of the Regulation of Speed of the Movement and Restriction of Speed of the Movement functions carries out EBU of system of injection. This block communicates with EBU ABS, TsEKBS, to EB AKP (if it is established) and a guard of devices. EBU of system of injection realizes preset values, issuing the operating commands for the block of a butterfly valve with the servo-driver or regulating supply of diesel fuel.

NOTE The blinking of an alarm lamp on a guard of devices shows that maintenance of the set speed is impossible (for example, at the movement under a bias).
