Abstract
Systems and methods for a global headlamp. An example method includes obtaining configuration information indicative of a jurisdiction associated with a vehicle. Headlamp state information is accessed which includes multiple headlamp states. A current headlamp state of the multiple headlamp states is determined based on the configuration information. A propagation is output via a pixelated light source in a headlamp of the vehicle, the propagation representing a particular beam pattern which is compliant with the jurisdiction.
Claims20
A computer-implemented method, the method performed by a headlamp controller included in a vehicle, the headlamp controller configured to control a headlamp of the vehicle, and the method comprising:
- obtaining configuration information indicative of a jurisdiction associated with the vehicle;
- accessing headlamp state information comprising a plurality of headlamp states;
- determining a current headlamp state of the plurality of headlamp states based on the configuration information, the current headlamp state indicating one or more luminous intensity values corresponding to one or more pixels of the headlamp;
- in response to determining that the configuration information indicates that the jurisdiction permits scaling of beam intensity, scaling an intensity of the one or more luminous intensity values by a scaling factor to generate one or more scaled luminous intensity values;
- and
- causing output, via a pixelated light source in the headlamp comprising the one or more pixels, of a propagation based on the one or more scaled luminous intensity values, the propagation representing a particular beam pattern which is compliant with the jurisdiction.
A vehicular system for propagating light that complies with requirements of multiple jurisdictions, comprising:
- a memory storing headlamp state information for a plurality of jurisdictions and a selection of a current jurisdiction, the headlamp state information for each jurisdiction indicating one or more luminous intensity values corresponding to one or more emissive elements;
- a controller that:
- reads the selected current jurisdiction and the headlamp state information associated with the selected jurisdiction;
- and
- in response to determining that the selected jurisdiction permits scaling of beam intensity, scales an intensity of the one or more luminous intensity values by a scaling factor to generate one or more scaled luminous intensity values;
- and
- a plurality of emissive elements, including the one or more emissive elements, configured to output propagations that are compliant with the selected jurisdiction based on the one or more scaled luminous intensity values.
A headlamp controller included in a vehicle, the headlamp controller controlling a headlamp of the vehicle, and the headlamp controller comprising one or more processing elements which are configured to:
- obtain configuration information indicative of a jurisdiction associated with the vehicle;
- determine a current headlamp state based on the configuration information, the current headlamp state indicating one or more luminous intensity values corresponding to one or more pixels of the headlamp;
- in response to determining that the configuration information indicates that the jurisdiction permits scaling of beam intensity, scaling an intensity of the one or more luminous intensity values by a scaling factor to generate one or more scaled luminous intensity values;
- and
- cause output, via a pixelated light source in the headlamp comprising the one or more pixels, of a propagation based on the one or more scaled luminous intensity values, the propagation representing a particular beam pattern which is compliant with the jurisdiction.
