Operation: (Use Cases) 

To activate VinPilot, the vehicle systems must detect/fulfill a number of conditions.

Operational readiness is signaled to the driver by the gray "VinPilot" display (1).

The following conditions can result in an inability to activate VinPilot:

• Neither the two lane markings nor a vehicle ahead are detected
• The lane width is less than 2.6 m or greater than 4.3 m
• The yaw rate of the vehicle is above the value of 0.2 rad/s for more than 3 seconds
• The absolute curvature of the road ahead is greater than 0.0033 m
• The vehicle must be within the intervention zone
• Vehicle stability systems (VSE/TCS, ABS/ESP) must be inactive for 3 seconds
• ESS function must be inactive
• Reverse gear is engaged
• Driver does not have his hands on the steering wheel (hands-on detection)
• Electric power steering (EPS) is unable to react normally

Should the operating conditions fail to be met from time to time, the system produces an acoustic signal and pop-up in the display (1) and head-up display, to alert the driver to the fact that he must take full control of the vehicle again.

If you press the "VinPilot" button on the steering wheel and the system is not available, the system distinguishes between two situations.

1. The conditions - see above - are not met

2. There is a technical defect/system error in the system

If there is a system error, the system displays the master warning light (4) and the pop-up warning "VIN Pilot not available" (5).

The system can detect a maximum of 6 objects ahead of the vehicle, and show their position and corresponding type. It distinguishes between trucks, cars, motorcycles, bicycles, pedestrians and unknown objects (e.g. objects lying on the road). It also shows lane boundaries, if these are detected by the system.

Activating VinPilot

1. Press the VinPilot button (1) on the steering wheel.

   The color of the VinPilot symbol in the HMI changes from gray to blue (2).

2. Press button (3) "GAP -" to decrease the distance to the vehicle in front by one bar.
3. Press button (3) "GAP +" to increase the distance to the vehicle in front by one bar.
4. Press button (4) "SPD -" to decrease the target speed.
5. Press button (4) "SPD +" to increase the target speed.
6. Press button (5) "RES/CAN" or press the brake pedal to cancel/resume the VinPilot function.

If, for example, there are no lane markings, VinPilot reduces the functionality to adaptive cruise control (ACC).

The VinPilot symbol changes from blue to yellow (1) and a corresponding message appears in the HMI (2).

If the vehicle comes to a standstill, a prompt (1) to press the "RES" button on the steering wheel or the accelerator/gas pedal to reactivate VinPilot or Adaptive Cruise Control (ACC) appears after 3 seconds.

After the following situations, the system is automatically set to standby mode:

• If, 5 minutes after the prompt shown above, there is no further action by the driver
• If the driver's door is opened
• If the driver's seat belt is not in the buckle
• If the system detects a system error

Deactivating Vinpilot

1. To deactivate Vinpilot, press the brake pedal or press the RES/CAN button on the right-hand side of the steering wheel.

Automatic High Beam (AHB) 

Automatic High Beam (AHB) is a driver assistance system that automatically switches from low beam to high beam as necessary. If the user has activated this function, the system switches from low beam to high beam when driving in situations with insufficient lighting. The high beam is automatically switched to low beam so as not to dazzle oncoming vehicles or those driving ahead.

Activation/deactivation of the high beam is dependent on the amount of light detected by the front camera. As soon as the system is activated, there are three scenarios that call for switching from high beam to low beam:

• Oncoming vehicles give off sufficient light
• The distance to a vehicle ahead of yours is so small that it is clearly visible in the low beam
• There is sufficient ambient lighting from daylight, street lights, etc.

As an autonomous system, this feature does not actively intervene in the dynamic driving task.

The system receives information on the lighting conditions from the S-Cam 4.8.

Operation: (Use Cases)

1. Select the app "Drive Aids" in the HMI's home screen.
2. Select the menu item "Lighting" (1).
3. Select "Exterior".
4. Slide the "Auto High Beam" selection switch to the "On" position.
