Detailed Description

The following describes the present invention with reference to the accompanying drawings. In which like parts are designated by like reference numerals. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.

Fig. 1 shows a system schematic diagram of a vehicle lighting system according to an embodiment of the present invention, which includes: lamp 1, the control unit 2, autopilot module 3 and light sensor 4, autopilot module 3's output with the first input communication connection of the control unit 2, light sensor 4's output with the second input communication connection of the control unit 2, the first output of the control unit 2 with the on-off control end communication connection of lamp 1, the second output of the control unit 2 with the brightness control end communication connection of lamp 1.

Specifically, the present embodiment is applied to a vehicle having an automatic driving function. The first output end of the control unit 2 is in communication connection with the switch control end of the lamp 1, and controls the signal of the first output end according to the signal of the first input end of the control unit 2, so as to control the lamp 1 to be turned on or turned off. The second output terminal of the control unit 2 is in communication connection with the brightness control terminal of the lamp 1, and controls the signal of the second output terminal according to the signal of the second input terminal of the control unit 2, thereby controlling the brightness of the lamp 1.

The automatic driving module 3 is an existing automatic driving module, and an output end of the automatic driving module outputs whether the vehicle is in an automatic driving state. The high level may be used to indicate that the vehicle is in an automatic driving state, and the low level may also be used to indicate that the vehicle is in an automatic driving state. The output end of the light sensor 4 may output a brightness signal of the external ambient light, and may also output a signal indicating whether the external ambient light exceeds a preset brightness threshold.

Preferably, when the automobile is in automatic driving, the control unit 2 receives the automatic driving state sent by the automatic driving module 3, the control unit 2 outputs a starting signal to the switch control end of the lamp 1 to drive the lamp 1 to be turned on, and the lamps 1 in other states are turned off. The switch control terminal may be a high-side driving circuit. The control unit 2 may control the lamp 1 to be turned on or off by outputting a high level or a low level.

As an example, the high-side driving circuit uses a field effect transistor to turn on and off the lamp 1. The source electrode of the field effect transistor is connected with a power supply end, the drain electrode of the field effect transistor is electrically connected with the power supply end of the light guide part of the lamp 1, and the grid electrode of the field effect transistor is used as a switch control end of the lamp 1. The field effect transistor is switched on and switched off when the grid receives a high level, and is switched off when the grid is a low level. Therefore, when the control unit 2 outputs a high level, the field effect transistor is turned on, the light guide part of the lamp 1 is turned on by power, and when the control unit 2 outputs a low level, the field effect transistor is turned off and turned off, and the light guide part of the lamp 1 is turned off by power loss.

The control unit 2 can be a controller such as a single chip microcomputer and a microcontroller. Preferably, the control unit 2 is a left Body Control Model (BCML). The control unit 2 may also be implemented using a logic circuit, for example, if the signal of the automatic driving state is identical to the signal of the control lamp 1, the signal of the first input terminal may be directly output to the first output terminal, or if the signal of the automatic driving state is opposite to the signal of the control lamp 1, the signal of the first input terminal may be converted by a not gate and then output to the first output terminal.

The output end of the light sensor 4 can output the brightness signal of the external environment light, the control unit 2 compares the signal received by the second input end with a preset brightness threshold, if the signal received by the second input end is greater than the preset brightness threshold, the second output end of the control unit 2 outputs a mode control signal for identifying the day, and if the signal received by the second input end is less than or equal to the preset brightness threshold, the second output end of the control unit 2 outputs a mode control signal for identifying the night.

The output end of the light sensor 4 can output a signal indicating whether the external ambient light exceeds a preset brightness threshold, when the signal received by the second input end of the control unit 2 is the signal indicating that the external ambient light exceeds the preset brightness threshold, the second output end of the control unit 2 outputs a mode control signal indicating the daytime, and if the signal received by the second input end is the signal indicating that the external ambient light is less than or equal to the preset brightness threshold, the second output end of the control unit 2 outputs a mode control signal indicating the night.

The control unit 2 can be a controller such as a single chip microcomputer and a microcontroller. Preferably, the control unit 2 is a BCML. The control unit 2 may also be implemented by a logic circuit, for example, if the output end of the light sensor 4 outputs a brightness signal of external ambient light, the signal of the second input end of the control unit 2 may be electrically connected to the first input end of the comparator, the second input end of the comparator is electrically connected to the preset threshold voltage, and the output end of the comparator is electrically connected to the second output end of the control unit 2. If the output end of the light sensor 4 can output a signal indicating whether the external ambient light exceeds the preset brightness threshold, the signal at the second input end of the control unit 2 can be output to the second output end of the control unit 2 directly or through a not gate.

As an example, the second output terminal of the control unit 2 is communicatively connected to the brightness control terminal of the lamp 1 via a hardwire enable, outputting the mode control signal to the lamp 1. Wherein, the high-side driving is 'night' and the suspension is 'day', and the lamp 1 adjusts the brightness of the lamp according to the hard wire enabling foot.

As an example, the high-side driving circuit uses a field effect transistor to achieve brightness adjustment of the lamp 1. The source electrode of the field effect tube is connected with a power supply end, the drain electrode of the field effect tube is electrically connected with the brightness adjusting end of the light guide part of the lamp 1, and the grid electrode of the field effect tube is used as the brightness control end of the lamp 1. The field effect transistor is switched on and switched off when the grid receives a high level, and is switched off when the grid is a low level. Therefore, when the control unit 2 outputs a high level, the field effect transistor is closed and switched on, the brightness control end of the light guide part of the lamp 1 receives the high level to increase the brightness of the light guide part, and when the control unit 2 outputs a low level, the field effect transistor is closed and switched off, the brightness control end of the light guide part of the lamp 1 is suspended, and the brightness of the light guide part is reduced.

The brightness control of the light guide can be achieved using existing techniques.
