example 1
[0249] according to figure 1 &2, Table 1 and according to Figure 5 The method described in Example 1 below describes.
[0250] Due to the environmental parameter data received by the controller 3 from the sensors 4, 5, 6, the controller 3 can determine that it is raining (second column in Table 1, step 201), and from several available lighting configurations (the first list ) to select a suitable lighting configuration (the third column in Table 1, step 202):
[0251] ·DRL ON
[0252] ·Position light ON
[0253] · Low beam ON
[0254] The name of this choice is identified as rainy day choice (second column in Table 1). By performing this selection, the controller 3 avoids selecting some lighting configurations that are useless or unsafe when it is raining, or that might confuse a driver who needs to select a new lighting configuration.
[0255] Control 3 then assigns to each selected lighting configuration a lighting configuration level (fourth column in Table 1, step 2...

Abstract
The invention concerns a lighting control system and a lighting control method to implement, in an automotive vehicle, external running lights (7-12) in different available lighting configurations. The lighting control method comprises the steps of a) detecting at least one environment parameter (101, 201, 301); b) selecting among the different available lighting configurations and depending on said parameter, which lighting configurations can be implemented (102, 202, 302); c) depending on said parameter, defining in which order the selected lighting configurations are implemented when an input device (2, 21, 22, 23, 24, 25) is manually actuated (103, 203, 303); d) detecting (104, 204, 309) a manual actuation on the input device (2, 21, 22, 23, 24, 25); e) depending on a motion of the input device (2, 21, 22, 23, 24, 25) or a motion on the input device, implementing at least one lighting configuration that is chosen among the selected lighting configurations according to the implementation order (105, 206, 310).
Description
technical field [0001] The invention relates to a lighting control system and a lighting control method for implementing and controlling exterior running lights of a motor vehicle. Background technique [0002] Traditionally, exterior running lights are controlled by rotary switches or stalk switches. These switches are mechanical systems that can have multiple physical positions, each of which corresponds to the illumination state of the exterior running lights. [0003] Typically, in the case of a rotary switch or a stalk switch, the first switch position indicates the OFF position of the lamp; the second switch position indicates the position lamp ON, and the third position indicates the low beam / high beam ON. [0004] Modern vehicles can further be equipped with light sensors capable of detecting the intensity of daylight. Based on the information detected by the sensors, the vehicle controller can turn on the lights as position lights or dipped beam without any input ...
