Abstract
The invention discloses a passenger car illumination curve supplementary lighting control system. The system has two supplementary lighting modes, namely, a first mode that a corner lamp luminescent source is combined and mounted with a fog lamp is suitable for low-velocity driving city roads, and a second mode that a dipped headlight is used for supplementary lighting is suitable for high-velocity curve driving roads. The system monitors the switching on/off information of a steering lamp and the corner sensor information of a steering wheel in real time to judge whether a vehicle is in curve driving; if a steering lamp at one side is switched on, and/or the corner of the steering wheel is greater than a set value, a supplementary lighting lamp is automatically lightened on and a corresponding supplementary lighting mode is started; when the speed is smaller than or equal to 40 KM/H, the system adopts the city supplementary lighting mode, and the corner lamp luminescent source is adopted for supplementary lighting; when the velocity is greater than 40 KM/H, the high-velocity supplementary lighting mode is adopted, and the dipped headlight at one side of the curve is adopted for supplementary lighting, the view of driving at night is increased, and the driving safety is improved.
Description
Technical field
The present invention relates to Passenger Car Illumination field, espespecially a kind of Lighting System and and vehicle light supplement control method that can increase passenger vehicle traffic safety.
Background technology
The head lamp that general vehicle configures only has dipped beam and distance light two kinds of light illumination modes, and it is mainly used in the illumination of road ahead, and the forward and backward fog lamp configured only has single light prompt function, for informing the position that vehicle travels at rainy day, thick fog and haze weather vehicle, be convenient to front or rear to the differentiation of vehicle location, but along with the development of society and the progress of technology, the ambient environment that automobile travels become become increasingly complex various, speed limit as road is different, the illumination on road surface is different, the density of pedestrian is different, the environment of weather condition is different, make traditional front photograph etc. cannot meet the growing driving safety needs of people, therefore people generally wish on automobile, to install a kind of Lighting System that can significantly improve traffic safety and comfortable driving, this Lighting System can adjust self light-configuration mode according to ambient environment, larger illumination zone and illumination distances are provided, also can improve the illumination dead angle of traditional head lamp simultaneously, so industry develops a kind of automatic bend auxiliary lighting system contributing to also bending light.
Automatic bend auxiliary lighting system (also known as follow-up steering Lighting System) mainly to adopt in head lamp lamp group, arranges a set of kinematic mechanism to rotate to drive bulb and Lamp cup, the light angle of head lamp is adjusted up and down according to the driving trace of vehicle, for chaufeur provides best road illumination effect, this Lighting System mainly applies to compact car field at present, but because passenger vehicle structure differs greatly with car, front wall radian is less, utilize the light angle scope of kinematic mechanism adjustment head lamp little, city intersection turning visual field demand can not be met, simultaneity factor more complicated, cost has high input, be not suitable for applying on passenger vehicle.
Simultaneously the control system of Passenger Car Illumination in the past, as shown in Figure 1, connects often through combined switch 1a, splitter box 2a and each lamplight component 3a, and wherein this splitter box 2a complex structure, the large maintenance cost of volume are high; The connection lead of this Lighting Control Assembly is very many simultaneously, not easily investigates once break down, and the independence that also cannot realize left and right passing light controls, thus also cannot realize the Based Intelligent Control of Passenger Car Illumination device.
In view of this, the present inventor, for above-mentioned defect in-depth study of the prior art, has this case to produce then.
