General information
Cars are equipped with two types of devices:
- cruise control allows you to maintain the speed selected by the driver. This feature can be disabled at any time by pressing the brake pedal, clutch pedal or one of the system switches;
- The speed limiter allows the driver to set a speed limit. After the car reaches the set speed. depressing the accelerator pedal does not lead to a further increase in speed.
The selected longitudinal speed can be exceeded at any time by overcoming the resistance of the accelerator pedal.
These functions are controlled by the injection ECU, which communicates with the automatic transmission ECU and the instrument panel. The setpoints are realized by means of an electrically actuated throttle valve.
Note. Page flashing «ADAC» (on-board computer) or displays indicate to the driver that maintaining the set speed is not possible (e.g. when driving downhill).
How cruise control works
Activation conditions:
- switch in position "Cruise control";
- 2nd gear recognized by the ECU;
- speed not less than 30 km/h. over 200 km/h (for reference);
- indicator light is solid green (Cruise control);
- pressing the switch «+», «-» or «restoration of the set speed».
Shutdown conditions:
- depressing the accelerator pedal
- pressing the brake or clutch pedal;
- pressing the switch "0";
- switch in position «turned off»;
- intervention of the trajectory stabilization system;
- injection computer intervention;
- transmission is not included.
Pressing the accelerator pedal temporarily disables cruise control. Releasing the accelerator pedal will restore the system to normal.
Note. A flashing speed setpoint indicates to the driver that the set speed cannot be maintained.
The principle of operation of the speed limiter
Activation conditions:
- switch in position «Speed limiter»;
- 2nd gear recognized by the ECU;
- driving speed not less than 30 km/h, not more than 200 km/h (for reference);
- indicator light is continuously amber (speed limiter);
- pressing the switch «+», «-» or «restoration of the set speed».
Shutdown conditions:
- hard pressing on the accelerator pedal (overcoming resistance);
- switch in position «shutdown»;
- intervention of the trajectory stabilization system;
- injection computer intervention;
- pressing the switch «0».
When you press the accelerator pedal, the system is temporarily disabled. Releasing the accelerator pedal will restore the system to normal.
