- with CODE (615) Bi-xenon headlamp unit with integrated curve illumination

Dynamic curve illumination
The dynamic curve illumination ensures optimum illumination of curves. A conventional bi-xenon headlamp serves as the basis which as previously makes available high beam and low beam. The entire headlamp unit is mounted in a mounting frame so that it pivots. When steering into a curve, this also pivots inward. The system functions both as a low beam and a high beam.

Dynamic curve illumination actuation depends on the following set variables:
^ Steering angle
^ Vehicle speed
^ Yaw rate

Dynamic curve illumination is achieved by the horizontal swiveling of the headlamp unit. The direct input parameter is the steering angle, for it describes the driver's direction requirement. The vehicle speed influences the control response of the swivel angle relative to the steering angle.

Actuation
The left dynamic curve illumination motor (E1m2) and the right dynamic curve illumination motor (E2m2) are actuated by the xenon headlamp control unit (E1n1) and the xenon headlamp control unit (E2n1). The xenon headlamp control unit (E1n1) actuates the left dynamic curve illumination motor (E1m2) in the left front lamp unit (E1). The xenon headlamp control unit (E2n1) actuates the right dynamic curve illumination motor (E2m2) in the right front lamp unit (E2).

The adjustment request is calculated by the headlamp range adjustment control unit (N71) and passed on to the xenon headlamp control unit (E1n1) and the xenon headlamp control unit (E2n1) for actuation.
