Abstract
Method and apparatus are described for controlling the roadway illuminating position of a motorcycle headlight during cornering of the motorcycle by determining a basic desired optical axis deflection angle for the headlight in response to the turning radius of the vehicle and, coincident therewith, correcting the deflection angle in accordance with the determined longitudinal position of the motorcycle along the roadway turning line.
Claims10
A motorcycle headlight optical axis deflection control apparatus comprising:
- means for determining the turning radius of said motorcycle;
- means for computing from said turning radius a basic optical axis deflection angle at which said headlight illuminates a roadway turning line;
- control means operatively connected to said motorcycle headlight for deflecting the optical axis of said headlight in accordance with the computed basic optical axis deflection angle;
- means for determining the longitudinal position of said motorcycle along said roadway turning line;
- and
- means for correcting the deflection of said headlight optical axis in response to the position of said motorcycle along said roadway turning line.
A method of controlling the optical axis deflection angle of a motorcycle headlight comprising the steps of:
- determining the turning radius of the motorcycle;
- computing a basic optical axis deflection angle at which said headlight illuminates a roadway turning line;
- determining the position of the motorcycle along said roadway turning line;
- and
- positioning the headlight of the motorcycle headlight in response to the computed basic optical axis deflection angle as
- corrected in response to the position of the motorcycle along said roadway turning line.
