Vehicle front lighting apparatus and disconnection detection method
Abstract:
A vehicle front lighting apparatus includes a lighting device array in which multiple lighting devices are connected in series, multiple bypass circuits, multiple switch elements, a lighting intensity detector, a lighting schedule generator, a lighting controller, a current value detector, a voltage value controller, a detector, and a disconnection determiner. When there is the switch element to be brought into a closed state during a prohibition period from a lighting timing to a post-lighting timing, the lighting schedule generator changes a timing at which the switch element is brought into the closed state outside the prohibition period. The disconnection determiner determines that a disconnection has occurred in any of the bypass circuits when the number of switch elements detected at the post-lighting timing does not match a voltage value.
