Method for automatically controlling lighting unit in inner space of vehicle, involves switching on lighting unit, when switch is set in on-state and to-be-viewed object is present in detection space

摘要

The method involves providing information representing change of ambient brightness based on detected data, when the ambient brightness is reduced in specific direction from vehicle traffic route. The probable position of lighting fall on route and state of switch is determined (S1). The determination of whether a to-be-viewed object is present in detection space is performed (S3). A lighting unit (5) is switched on (S6), when switch is set in on-state and to-be-viewed object is present in detection space. An independent claim is included for a device for automatically controlling lighting unit in inner space of vehicle.
