A method for providing driver assistance to a driver of a vehicle, comprising: providing a vehicle with a visible-light source emitting visible light and having a function of illuminating an environment adjacent to the vehicle or emitting a signal, said visible-light source being a light emission diode; the method being characterised in that it further comprises the following steps: driving the visible-light source to emit pulsating visible light in a predetermined mode using driving data, with visible light in the predetermined mode being visible to an unaided human eye to maintain said function of illuminating an environment adjacent to the vehicle or emitting a signal; receiving a reflection/backscatter of the emitted pulsating visible light from an object and generating detected light data therefrom, said detected light data being digitalized; identifying at least one of a presence and a position of the object using said driving data and said detected light data; wherein said identifying uses a relation between said pulsating visible light driven by said driving data and said detected light data; and triggering at least one of an interaction with a driver of the vehicle and an action of the vehicle as a function of at least one of the identified presence of the object and the identified position of the object. providing a vehicle with a visible-light source emitting visible light and having a function of illuminating an environment adjacent to the vehicle or emitting a signal, said visible-light source being a light emission diode; the method being characterised in that it further comprises the following steps: driving the visible-light source to emit pulsating visible light in a predetermined mode using driving data, with visible light in the predetermined mode being visible to an unaided human eye to maintain said function of illuminating an environment adjacent to the vehicle or emitting a signal; receiving a reflection/backscatter of the emitted pulsating visible light from an object and generating detected light data therefrom, said detected light data being digitalized; identifying at least one of a presence and a position of the object using said driving data and said detected light data; wherein said identifying uses a relation between said pulsating visible light driven by said driving data and said detected light data; and triggering at least one of an interaction with a driver of the vehicle and an action of the vehicle as a function of at least one of the identified presence of the object and the identified position of the object. driving the visible-light source to emit pulsating visible light in a predetermined mode using driving data, with visible light in the predetermined mode being visible to an unaided human eye to maintain said function of illuminating an environment adjacent to the vehicle or emitting a signal; receiving a reflection/backscatter of the emitted pulsating visible light from an object and generating detected light data therefrom, said detected light data being digitalized; identifying at least one of a presence and a position of the object using said driving data and said detected light data; wherein said identifying uses a relation between said pulsating visible light driven by said driving data and said detected light data; and triggering at least one of an interaction with a driver of the vehicle and an action of the vehicle as a function of at least one of the identified presence of the object and the identified position of the object.
