Abstract
The invention discloses a kind of Passenger Car Illumination bend light filling control system, the system has two kinds of light filling modes：One is by combining the corner lamp illuminating source installed with fog lamp, it is adaptable to the urban road run at a low speed；Two be to carry out light filling by dipped headlight, it is adaptable to the road of high speed negotiation of bends.System by monitoring turning indicator control state and steering wheel angle sensor information in real time, judge vehicle whether turning driving, if one it is side steering indicating light installed open, and/or steering wheel angle is more than setting value, then light compensating lamp is lighted automatically, into corresponding light filling pattern；As speed≤40KM/H, system uses city light filling pattern, i.e., using corner lamp illuminating source light filling；Speed ＞ 40KM/H, system uses high speed light filling pattern, i.e., using the dipped headlight light filling of bend side, to increase the night traveling visual field, improves driving safety.
Description
Technical field
The present invention relates to Passenger Car Illumination field, espespecially a kind of illuminator that can increase car traffic safety and and vehicle benefit
Light control method.
Background technology
The headlamp configured on general vehicle only has two kinds of light illumination modes of dipped beam and distance light, and it is mainly used in front road
The illumination on road；And the forward and backward fog lamp configured only have single light prompt function, for inform vehicle the rainy day, thick fog and
The position of haze weather vehicle traveling, is easy to differentiation of the front or behind to vehicle location；But development and technology with society
Progress, the surrounding enviroment that automobile is travelled have become to become increasingly complex various, the speed limit of such as road is different, road surface illumination not
Together, the density difference of pedestrian, the environment difference of weather condition so that traditional preceding photograph etc. can not meet the growing row of people
Sail security needs, therefore people generally wish to install on automobile and a kind of can significantly improve traffic safety and comfortably drive
Illuminator, this illuminator can adjust the light-configuration mode of itself according to surrounding enviroment, and there is provided bigger illumination zone and photograph
Prescribed distance, while can also improve the illumination dead angle of traditional headlamp, then industry develop it is a kind of contribute to also bending light from
Dynamic bend auxiliary lighting system.
Automatic bend auxiliary lighting system（Also known as：Follow-up steering illuminator）It is main to be arranged using in headlamp lamp group
A set of motion drives bulb and the Lamp cup to rotate, and adjusts the illumination angle of headlamp up and down according to the driving trace of vehicle
Degree, provides optimal road lighting effect, this illuminator mainly applies to compact car field at present for driver, but due to visitor
Car construction differs greatly with car, and front wall radian is smaller, and the light angle scope for adjusting headlamp using motion is small, it is impossible to
City intersection turning visual field demand is met, simultaneity factor is more complicated, cost input is big, be not suitable for promoting on car and answer
With.
The control system of conventional Passenger Car Illumination simultaneously, as shown in figure 1, often through stacked switch 1a, block terminal 2a and
Each lamplight component 3a is attached, and wherein block terminal 2a is complicated, the big maintenance cost of volume is high；While the Lighting control
The connecting line of system is very more, is difficult investigation once breaking down, can not also realize the independent control of left and right dipped headlight, so that
Also the intelligent control of Passenger Car Illumination device can not be realized.
In view of this, the present inventor furthers investigate for drawbacks described above of the prior art, there is this case generation then.
The content of the invention
Present invention is primarily aimed at providing one kind to increase coach front surrounding light source range of exposures, lifting car is then realized
The fog lamp of traffic safety；
The second object of the present invention is to provide a kind of coach front surrounding lighting device for installing above-mentioned fog lamp；
The third object of the present invention is to provide a kind of Passenger Car Illumination system to contain coach front surrounding lighting device；
The fourth object of the present invention is to provide a kind of light light compensation method for being used to control the Passenger Car Illumination system.
To achieve the above object, solution of the invention is：
A kind of front fog lamp of car, it includes lamp housing, fog lamp illuminating source, corner lamp illuminating source and light source reflecting surface, institute
The fog lamp illuminating source stated is arranged side by side inside same lamp housing with corner lamp illuminating source, and its rear end, which is provided with, to be used to make fog lamp light
