Adaptive Headlight: Swiveling
The following signals are made available to the footwell module for the purpose of moving the swivel module.
- Steering angle
- Road speed
- Yaw rate.
Under normal driving conditions, the adaptive headlight is controlled by the data from the steering angle sensor up to a speed of approximately 40 kph (25mph).
COMPONENTS DESCRIPTION CHART
| Index | Explanation |
|---|---|
| 1 | Vehicle speed |
| 2 | Steering angle |
| 3 | Yaw rate |
The yaw rate sensor is included in the calculation
- at speeds higher than approximately 40 km/h (25 mph)
- in the event of vehicle oversteering or understeering
- a vehicle tending to yaw.
The wheel speed sensors supply the signals for the vehicle speed. The dynamic stability control evaluates the wheel speed sensor of each wheel.
The vehicle oversteering/understeering or yawing is detected by means of the steering angle sensor and the yaw rate sensor.
The adaptive headlight is deactivated in the event of the vehicle oversteering/understeering or yawing. The swivel module returns to its zero position.
NOTE:
The yaw rate sensor makes available signals relating to the yaw of the vehicle about the vertical axis. It is installed between the driver's and front passenger seats on the transmission tunnel.
The steering angle sensor is integrated in the steering column switch cluster. It is an optical sensor and makes available data relating to the steering wheel lock angle.
