Audi Q7: Predictive control

Applies to: vehicles with Audi adaptive cruise control and efficiency assist

Fig. 111 Instrument cluster: speedometer: predictive control display

With predictive control, efficiency assist adapts the set speed in adaptive cruise control (1) based on detected speed limits and the upcoming route. Once the system no longer detects any incidents ahead, adaptive cruise control will accelerate back up to the last speed that the driver set. After switching on the ignition, the availability of predictive control is indicated by a message when the adaptive cruise control is first activated.

Incident symbols indicate the situation to which predictive control is reacting, Situation symbols.

Requirements

• Predictive control is switched on in the MMI
• Adaptive cruise control is actively regulating
• The system can only react to speed limits that are 15 mph (20 km/h) or higher.

Display in the speedometer

The display depends on vehicle equipment and is not available in all layouts".

1. The marking shows the set speed (regulated speed that was set by the driver or by predictive control).
2. The red band shows the difference between the speed limit and the set speed that is set.
3. The gray band shows if the vehicle speed is planned to drop below the set speed due to the road layout.

Overriding control

The driver can override the predictive control based on the route ahead at any time by pressing the accelerator pedal. If the system changes the vehicle speed to adapt to speed limits, you can change the speed using the lever, fig. 109.

Messages

If and a message with Predictive control is displayed when there is a malfunction, the efficiency assist functions are unavailable or limited.

A message that indicates the cause and possible solution may appear with some displays. The weather conditions may be too poor or a sensor may be covered. Clean the area in front of the sensors and try to turn on the systems again later.

If the malfunction remains, drive to an authorized Audi dealer or authorized Audi Service Facility immediately to have the malfunction corrected.

WARNING

• Observe the safety precautions and note the limits of the assist systems, sensors, and cameras.
• Pay attention to traffic and the area around your vehicle when predictive control is switched on. The driver is always responsible for assessing the traffic situation.
• The system does not consider "right of way" rules and does not respond to traffic lights, so lack of driver attention in these situations can increase the risk of an accident.
• The speed when driving through curves may be different from what you as a driver would do or may not be suitable for the weather and road conditions. If necessary, apply the brakes and reduce the selected speed to be maintained in the Adjustment to curves along route setting to reduce the risk of an accident.

Tips

• Predictive control can exceed or drop below the maximum permitted speed. The driver is responsible for adhering to the permitted speed limit.
• The traffic signs on the road always take priority over the display. The driver is always responsible for adhering to the regulations applicable in the country where the vehicle is being operated.
• If a speed limit is detected, the marking (1) of the set speed limit will be adjusted even if Audi adaptive cruise control is not actively regulating.
• Control by the system depends on which adaptive cruise control driving program is set or on the selected Audi drive select* mode.
• After switching on the ignition and first driving onto a freeway or similar road without a speed limit, the system will regulate the speed to 80 mph (130 km/h)¹⁾. Then the system adjusts to the last speed set by the driver.
• There is no adaptation to speed limits when driving through highway interchanges and when driving on or off the expressway.
• The system can fail to provide control or the control may be faulty if the values from the camera-based traffic sign recognition* are incorrect or the navigation system map data is outdated.
• When route guidance is switched on, the system adapts to the route provided by the navigation system. Driving without route guidance or leaving a route can result in faulty control.
