Passenger car front fog lamp, illuminating system comprising same and supplementary lighting control method

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 [0001] The invention relates to the field of passenger car lighting, in particular to a lighting system capable of increasing the driving safety of passenger cars and a vehicle supplementary light control method. Background technique [0002] Generally, the headlights configured on vehicles only have two lighting modes of low beam and high beam, which are mainly used for lighting the road ahead; while the front and rear fog lamps only have a single light reminder function, which is used to inform the vehicle In rainy days, dense fog and smog weather, the driving position of the vehicle is convenient for identifying the position of the vehicle from the front or the rear; however, with the development of society and the advancement of technology, the surrounding environment of the vehicle has become more and more complex and diverse. For example, the speed limit of the road is different, the lighting of the road surface is different, the density of pedestrians ...

Problems solved by technology

[0002] Generally, the headlights configured on vehicles only have two lighting modes of low beam and high beam, which are mainly used for lighting the road ahead; while the front and rear fog lamps only have a single light reminder function, which is used to inform the vehicle In rainy days, dense fog and smog weather, the driving position of the vehicle is convenient for identifying the position of the vehicle from the front or the rear; however, with the development of society and the advancement of technology, the surrounding environment of the vehicle has become more and more complex and diverse. For example, the speed limit of the road is different, the lighting of the road surface is different, the density of pedestrians is different, and the weather conditions are different, so that the traditional front light cannot meet people's growing driving safety needs. Therefore, people generally hope to install a A lighting system that can significantly improve driving safety and comfortable driving. This lighting system can adjust its own light distribution method according to the surrounding environment, provide a larger lighting range and lighting distance, and can also improve the lighting dead angle of traditional headlights, so The industry has developed an automatic cornering assist lighting system that helps illuminate corners

[0003] The automatic cornering auxiliary lighting system (also known as: follow-up steering lighting system) mainly uses a set of motion mechanisms arranged in the headlight lamp group to drive the bulbs and lamp cups to rotate, and adjust the position of the headlights up, down, left, and right according to the vehicle's driving track. The lighting angle provides the driver with the best road lighting effect. This lighting system is mainly used in the field of small cars at present. However, due to the large difference between the structure of the bus and the car, and the small curvature of the front wall, the lighting of the headlights is adjusted by using the movement mechanism The range of angles is small, which cannot meet the needs of turning vision at urban intersections. At the same time, the system is relatively complicated and the cost is large, so it is not suitable for popularization and application on buses.

[0004] At the same time, the previous passenger car lighting control system, such as figure 1 As shown, it is often connected through the combination switch 1a, the power distribution box 2a and each lighting component 3a, wherein the power distribution box 2a is complex in structure, large in size and high in maintenance cost; It is not easy to check, and it is impossible to realize the independent control of the left and right low beams, so that it is impossible to realize the intelligent control of the lighting device of the bus
