Abstract
An apparatus for determining roll angle of a motorcycle () as when taking a curve or bend in a road. The apparatus includes a first gyro sensor () that provides a roll rate signal, a second gyro sensor () that provides a yaw rate signal, and a velocity sensor (). The apparatus is configured to integrate the roll rate signal to obtain a first intermediate roll angle value and to determine a second intermediate roll angle value from the yaw rate and the vehicle velocity. The apparatus combines the two intermediate roll angle values into an output value for the roll angle that can be used by a servo () to adjust the orientation of the headlamp so that the beam pattern remains leveled with the horizon when the motorcycle () rolls when taking a curve.
