The three-position switch provides inclusion and switching off of the regulator or limiter of speed.

Switches on a steering wheel are intended for change of the set speed, cancellation of function or a call of value of speed from memory.

The general are used with system of injection the sensor of provision of a pedal of an accelerator and the switch of a stoplight.

The sensor of the course of a pedal of coupling is intended especially for function of maintenance of the set speed. This sensor can be used by system of injection also.

NOTE On the car two sensors of provision of a pedal of coupling are installed: for start-off of the car from the place (the sensor of the end of the course of a pedal) and for system of regulation of speed (the sensor of the beginning of the course of a pedal). The pedal of an accelerator has the safety switch at the end of the course.

EBU of system of injection.

EBU of system of injection receives on multiplex network:

– information on car speed (from EBU ABS);

– a signal from the closing contact of the switch of a stoplight (from TsEKBS);

– information on the included transfer (from EB AKP if it is established).

EBU of system of injection sends on multiplex network:

– a preset value of the regulated or limited speed on a guard of devices;

– a signal on inclusion by the constant or blinking light of a two-color alarm lamp on a guard of devices;

– the operating commands for the block of a butterfly valve with the servo-driver or on the regulator of supply of diesel fuel;

– information on switching of transfer of AKP (if it is established).

EBU of system of injection obtains information on wire communication:

– from the sensor of provision of a pedal of an accelerator;

– from the stoplight switch (has two contacts: disconnecting and closing);

– from the coupling pedal course sensor (if it is);

– signal of the three-position switch;

– from governing bodies on a steering wheel.
