Driver behaviour detection
Driver behaviour detection is used to verify that specific conditions are met when driving and using certain features. Two cameras, one located by the driver display and one located just above the centre display, continuously track the driver's behaviour without recording it. The information from this system is used by several driver support features.
- Head and body posture
- Eye movement and focus
- Signs of tiredness or fatigue
An important part of the monitoring system is checking that the driver's hands are on the steering wheel when driving.
Note
System for understanding the driver
In addition to tracking the driver's attention, the car monitors some other parts of driving. This includes keeping the doors closed and seatbelts buckled while driving. The individual detection points are combined to form a better understanding of the driver's focus, attention and behaviour.
Information from the behaviour detection system is combined to identify whether the driver's attention is focused on driving. This includes keeping track of traffic and surroundings, as well as being attentive and alert. The detection system can give you notifications in the driver display.
Reliant features and functions
The driver behaviour detection system keeps track of the driver's behaviour to decide if the car is being handled safely. If the system is blocked, or detects driver misuse, it can trigger a response from several other features or functions of the car.
| Driver alert | Driver alert can notify you if you seem tired, distracted or unfocused. |
| Emergency stop assist | In situations where the driver is unable to continue driving, the car can perform a controlled stop to reduce the risk of a collision. |
| Adaptive cruise control | Adaptive cruise control can be deactivated if you seem unfocused or don't respond to requests to keep your hands on the steering wheel. |
Conditions and limitations
The driver behaviour detection system relies on cameras for detection and tracking. While the system is advanced, cameras have limitations connected to visibility that can affect the system's detection capabilities. Read the separate section about the conditions and limitations of your car's cameras to understand how features relying on camera detection are affected.
- Attention tracking requires an unobscured view of the driver's face.
- Improperly stowed items can obscure the view of the driver, as can dust and dirt on the camera lens. Keep the driver's space clean and clutter-free.
- Wearing certain clothing and accessories can obstruct parts of the driver's face that need to be visible for attention tracking, such as the eyes.
- Dirt in front of the cameras can negatively affect their detection capabilities.
- Certain conditions can affect how well your car can assess your driving and manoeuvring. This in turn affects how well it can distinguish signs of an unfocused or tired driver.
- Features that help with lane placement can sometimes compensate for manoeuvring that would otherwise indicate a lack of driver focus. This makes it harder to identify signs of lacking focus compared to unassisted driving.
- Conditions such as strong winds or uneven road surfaces can affect your driving in ways similar to that of an unfocused driver. This can potentially cause warnings despite having a fully focused driver behind the wheel.
Important
Affecting the system
Do not cover the cameras. The cameras can be fully or partially obscured by objects hung or placed on or around the driver display or the centre display. Objects placed on the dashboard can fall down or become misplaced so that they cover the cameras' views. If the cameras are obscured or covered, your car can notify you with a message in the driver display.
Do not intentionally try to trick the driver behaviour detection system. The system is there to keep driving as safe as possible. By limiting the system's ability to detect a dangerous situation, you also limit its ability to perform a safety intervention.
