The lighting state driving controller adapts the system action distance of the corresponding peak lighting street lamp according to the speed information of the vehicle; and the lighting state driving controller adapts and adjusts the peak lighting power of the target street lamp at the end point position of the system action distance according to the system action distance.
The illumination intensity of the target street lamp in the subsequent driving direction of the vehicle is synchronously and linearly changed along with the distance parameter between the target street lamp in the subsequent driving direction of the vehicle and the driving vehicle, and the illumination power of the street lamp closer to the driving vehicle is reduced along with the change.
In the invention, an initial street lamp position is set as N, and street lamp positions in the vehicle driving direction are sequentially N +1, N +2.. N + X; setting the street lamp at the position of N + X as the destination target street lamp position of the peak lighting action in the driving direction; setting the distance between the lamp at the destination target street lamp position and the initial street lamp position as a system action distance L; setting a speed sensor 4 on the street lamp at the initial position to detect that the speed is V; then there is: the system operating distance L ∞ the vehicle speed V.

Example two
The prior publications are: illumination technical Manual 2 nd edition, mechanical industry Press 2003.11, ISBN 7-111-: zhu Xiao Qing, vice main edition: forest.
The book discloses chapter, chapter i, third chapter-light and vision, 1.3.1.2 vision; relationship of vision to exposure time-in order to see an object, a certain fixation time is required. If the illumination is increased, the shorter the press is required to see the object.
When people drive, when the illumination brightness on the road is the same, the far side is darker, the near side is clearer, and in order to clearly see the far side, the people may need to drive to a shorter distance to clearly see, but some hidden dangers exist, so that some dangerous accidents are caused.
In the invention, the illumination degree of the distant street lamp meeting the distance requirement is improved when the vehicle runs, so that a driver can see the distant situation in advance, and the illumination brightness of the target street lamp is gradually reduced and tends to be normal as the vehicle gradually approaches the target street lamp.
If more vehicles are running on the road, the street lamp lighting on the road section provides higher illumination according to the technical scheme of the invention, and the safe running of the road section can also be ensured.
When no vehicle is driving on the road segment, the illumination brightness of the road segment is reduced to normal illumination, such as the smooth illumination curve after the target street lamp position in fig. 3.
If the speed sensor detects that the current vehicle speed is high, the distance of the illuminating lamp for improving the brightness in advance is longer (the system action distance L is longer). For example, when the vehicle speed is 30KM/h, the illumination brightness of the 10 th street lamp in the distance is improved in advance; and when the vehicle speed is 50KM/h, the 14 th street lamp in the distance increases the illumination brightness in advance.
When the vehicle passes through the street lamp, the illumination brightness gradually decreases to a normal state.
In the invention, aiming at the improvement of illumination intensity, glare can not be caused to a driver, firstly, because the distance is longer, and secondly, because the brightness of the previous target street lamp is improved when the target street lamp of the system action distance from the terminal position is improved for illumination, and only the brightness is gradually reduced along with the distance between vehicles, the system is completely in a linear and soft illumination environment in the driving process of the vehicle, namely, the system feels that a light cage covers the front and the back of the vehicle and moves along with the driving of the vehicle, the overall illumination fluctuation is smaller, the illumination safety is ensured, and the electric energy is also saved.
