Operating method of internal illuminating equipment of motor vehicle, equipment and motor vehicle

The invention relates to an operating method for internal illuminating equipment (1, 1' and 1'') of a motor vehicle (8). The internal illuminating equipment comprises illuminating devices (L, L') andsensor devices (S, S'). The sensor devices detect the position of operating objects (6) of the illuminating devices (L, L') within the detecting range of the sensor devices, and the illuminating devices (L, L') are controlled according to data of sensors. The illuminating devices (L, L') are provided with a plurality of controllable illuminating units (L1-L3, L1'-L7'). A position section (O1-O3) limited within the detecting range is allocated for each illuminating unit correspondingly, and when the operating objects (6) are detected at one position section (O1-O3), the corresponding illuminating units (L1-L3, L1'-L7') are opened, and the opened illuminating units (L1-L3, L1'-L7') which do not correspond to the position section are closed. 本发明涉及用于机动车辆(8)的内部照明设备(1、1'、1")的操作方法，该内部照明设备包括照明装置(L、L')和传感器装置(S、S')，该传感器装置在它
