Abstract
A process, system and procedure of controls of the supply of a vehicle headlamp suitable to supply lighting in high beam function and/or low beam function, comprising the following stages for at least one of the low beam function and high beam functions: determining at least one driving parameter pertinent to the lighting of the vehicle, defining several lighting modes characterized by the value of this at least one parameter, attributing a supply mode of the headlamp to each lighting mode, and storing in memory the supply mode associated with each of the lighting modes.
Claims19
A procedure of controls of the supply of a vehicle headlamp suitable to supply lighting in high beam function and/or low beam function, wherein said procedure comprises the following stages for at least one among the low high beam function and the high beam function:
- determining at least one driving parameter pertinent to the lighting of the vehicle;
- defining a plurality of lighting modes characterized by the value of at least one parameter;
- attributing a supply mode of the headlamp to each lighting mode:
- storing in memory the supply mode associated with each of the lighting modes;
- wherein the supply modes are defined by carrying out the following stages:
- defining a desired life duration for the headlamp and/or desired maximum energy consumption of the headlamp for a given duration of use of the headlamp;
- defining a previously determined driving profile characterizing a relative duration of use of the headlamp in each of the lighting modes;
- and
- calculating a supply mode for each lighting mode, so that with this supply mode the headlamp provides lighting satisfactory for this lighting mode while presenting a life duration close to the desired life duration and/or while inducing an energy consumption close to the maximum energy consumption desired for a use corresponding to the previously determined driving profile.
A control device of the supply of a vehicle headlamp suitable to supply lighting in high beam function and in low beam function, wherein for at least one among the low and high beam functions, it is set up to:
- receive values concerning at least one parameter pertinent to the lighting of the vehicle;
- identify, among a plurality of lighting modes, a lighting mode corresponding to these values;
- and
- determine a supply mode of the headlamp in accordance with the identified lighting mode;
- wherein said control device is adapted to:
- determine at least one driving parameter pertinent to the lighting of the vehicle;
- define a plurality of lighting modes characterized by the value of at least one parameter:
- attribute a supply mode of the headlamp to each lighting mode;
- storing in memory the supply mode associated with each of the lighting modes;
- wherein the supply modes are defined by carring out the following stages;
- define a desired life duration for the headlamp and/or desired maximum energy consumption of the headlamp for a given duration of use of the headlamp;
- define a previously determined driving profile characterizing a relative duration of use of the headlamp in each of the lighting modes;
- and
- calculate a supply mode for each lighting mode, so that with this supply mode the headlamp provides lighting satisfactory for this lighting mode while presenting a life duration close to the desired life duration and/or while inducing an energy consumption close to the maximum energy consumption desired for a use corresponding to the previously determined driving profile.
A control device for controlling an electrical supply of a vehicle light source suitable to supply lighting in high beam function and/or low beam function, wherein said control device comprises:
- at least one sensor for determining at least one driving parameter pertinent to the lighting of the vehicle;
- a database stored in memory and defining a plurality of lighting modes characterized by the value of this at least one parameter;
- said database defining supply modes of the vehicle light source to each of said plurality of lighting modes;
- and
- a memory for storing said supply modes associated with each of said plurality of lighting modes;
- where said control device is adapted to:
- determine at least one driving parameter pertinent to the lighting of the vehicle;
- define a plurality of lighting modes characterized by the value of at least one parameter;
- attribute a supply mode of the headlamp to each lighting mode;
- and
- storing in memory the supply mode associated with each of the lighting modes;
- and
- wherein the supply modes are defined by carrying out the following stages;
- define a desired life duration for the headlamp and/or desired maximum energy consumption of the headlamp for a given duration of use of the headlamp;
- define a previously determined driving profile characterizing a relative duration of use of the headlamp in each of the lighting modes;
- and
- calculate a supply mode for each lighting mode, so that with this supply mode the headlamp provides lighting satisfactory for this lighting mode while presenting a life duration close to the desired life duration and/or while inducing an energy consumption close to the maximum energy consumption desired or the a use corresponding to the previously determined driving profile.
