With a conventional fixed headlight on a motorcycle,
banking the vehicle into a curve also results in a tilting
of the headlight that causes a change in the road illumination
to the inside of the curve.
With this in mind, the "Active Headlight" is
designed to reduce the amount of change in the field of illumination
and always maintain a flat plane of illumination on the road
surface during banking in order to improve visibility on
curves in night-time riding.
Data from a yaw rate sensor (vehicle turning sensor) mounted
on the motorcycle body and data concerning traveling speed
are processed by the control unit's ECU to render a calculation
of the machine's banking angle continuously and keep the
flat illumination to the road surface at all times by adjusting
the headlight beam axis by means of a motor-driven rotational
device.
Furthermore, the headlight bulb itself is an HID high illumination
type that compliments the active headlight action with brighter
illumination over a wider field on curves in night-time riding.
In particular, this system is characterized by its ability
to maintain even illumination of the road ahead while riding
on roads with curves coming in succession. |
