In fig. 2, reference numeral 10 denotes a left front wheel, reference numeral 20 denotes a right front wheel, and reference numeral 30 denotes a vehicle head, a side of the left front wheel 10 corresponding to the left rearview mirror 110 is a left side of the vehicle body, and a side of the right front wheel 20 corresponding to the right rearview mirror 210 is a right side of the vehicle body. It should be noted that fig. 2 simply shows the position relationship of each component, and the specific position may refer to an actual vehicle, which is not described herein again.
In this implementation, install left side direction lamp 100 and right side direction lamp 200 respectively on two rear-view mirrors of car, and arrange the outside of rear-view mirror in, design like this makes the light of side direction lamp can not sheltered from on the one hand, can provide sufficient illumination, and on the other hand for the position of side direction lamp and driver is nearer, makes the side direction lamp can help the driver to obtain better field of vision. In addition, the left side direction lamp 100 and the right side direction lamp 200 are installed outside the rear view mirror, are far away from the vehicle body, have a larger light diffusion range, and can improve a good illumination effect.
In other implementations, the left side light 100 may also be mounted on a left side door of the automobile, specifically a left side front door; the right side light 200 may also be mounted on a right side door of the automobile, specifically a right side front door.

Specifically, the left turn light 100 is integrated with the left turn light of the left rear view mirror 110 in the same lamp group, and the right turn light 200 is integrated with the right turn light of the right rear view mirror 210 in the same lamp group. The side direction lamp and the turn light are two independent light sources which are not influenced by each other, are integrated in one lamp set and then are installed on the outer sides of the left rear-view mirror 210 and the right rear-view mirror 210, and are convenient to arrange and manufacture. The lamp group may refer to a plurality of lamps which are arranged together and controlled by the same control circuit.
In the embodiment of the present invention, the control device 300 includes a mode selection switch 301, a photosensor 305, and a control unit 302, the mode selection switch 301 is used for providing a mode selection signal to the control unit 302 according to the driver selection, and the photosensor 305 is used for detecting whether the ambient brightness is less than a threshold value.
The control unit 302 is configured to obtain a mode selection signal, and determine a working mode of the automotive lighting system according to the mode selection signal, where the working mode is an off mode and an on mode; when the working mode is the closing mode, controlling the left side lamp 100 and the right side lamp 200 to be normally closed; when the operation mode is the on mode, if the ambient brightness is less than the threshold, the left side lamp 100 is controlled to emit light when the automobile turns left or the right side lamp 200 is controlled to emit light when the automobile turns right, and if the ambient brightness is greater than or equal to the threshold, the left side lamp 100 or the right side lamp 200 is controlled not to emit light. Here, the normally closed means that the left and right lateral lights 100 and 200 are always in an off (non-light emitting) state in the off mode.
The mode selection switch 301 can be arranged at the center control position of the instrument panel together with the audio and air conditioner control buttons, so that the operation of a driver is facilitated.
The light sensor 305 performs a determination according to a preset brightness threshold, and generates no electric signal if the ambient brightness is greater than or equal to the threshold. If the ambient brightness is less than the threshold, an electrical signal is generated, and the control unit 302 receives the electrical signal, determines that the current signal of the photosensor 305 satisfies the condition of lighting the side light, and controls the side light. The threshold corresponding to the ambient brightness can be set according to actual needs.
The photosensitive sensor 305 can be installed on the left side of the gutter channel at the lower part of the front windshield, and the specific position can be flexibly arranged as long as the ambient brightness can be accurately detected. The control unit 302 may be disposed at a lower portion of the front windshield, or may be disposed at a suitable position on the vehicle body according to actual conditions, see fig. 2.
Specifically, the turn-on mode may be further divided into a manual control mode in which the driver is required to control the left or right lateral light 100 or 200 to emit light by operation, and an automatic control mode in which the driver is not required to control the left or right lateral light 100 or 200 to emit light by operation, but the control device 300 performs the light emission control.
The mode selection switch 301 may be implemented by a switch with three gears (corresponding to the off mode, the manual control mode, and the automatic control mode, and the following several implementation modes are the same as those above), and different gears generate different mode selection signals; or three key switches can be adopted, and different keys generate different mode selection signals; the touch screen can be used for realizing that different touch positions generate different mode selection signals; or a switch with only one button is adopted, and different mode selection signals are generated according to different times of continuous triggering of the button.
When the vehicle is started, the driver can make a selection on the mode selection switch 301, which has three options, namely, an off mode, a manual control mode and an automatic control mode, when the off mode is selected, the function of the side lighting is not started, and the side lights are normally closed. When the on mode is selected, the control unit 302 firstly determines whether the ambient brightness is less than a threshold value according to the photosensitive sensor 305, if not, the control unit does not emit light, and if so, the control unit controls the side lights in the corresponding directions to emit light when the automobile turns. Wherein the side lights are normally on when they are illuminated. When the straight line is recovered, the side lights are turned off.
Because the side lights emit light when the automobile turns, the turn lights are simultaneously lightened and the turn lights are in a flashing state when the side lights emit light.
The system provides three different lighting modes, can meet the use requirements under different conditions, and has stronger practicability.
