The utility model relates to the field of auto parts, in particular to a daytime running light control system.

Background technique

Daytime running light control system, when the system collects the engine working signal, it lights up the daytime running lights in the headlights, and when the system collects the position light switch signal, it lights up the position lights, and the position lights and daytime running lights are multiplexed LEDs , When driving in the daytime, the daytime running lights can improve driving safety; when driving at night, the switching drive of the daytime running light controller can avoid safety hazards such as glare caused by the daytime running lights being too bright. The daytime running light control module in the prior art is inherited on the same chip as other car drive modules, which is inconvenient to replace and adjust.

Utility model content

In view of the above technical problems, the utility model provides a daytime running light control system, which integrates the daytime running light and the position light driving module, which can be applied to various types of vehicles while ensuring safe driving.

The utility model provides a daytime running light control system, which includes an MCU control module, the input end of the MCU control module is electrically connected with the output end of a power supply, a position light switch and the output end of a CAN transceiver, and the output end of the MCU control module is connected with a The running light driving module and the position light driving module, the daytime running light driving module is connected with the daytime running light, and the position light driving module is connected with the position light.

The daytime running light driving module and the position light driving module use the same driving chip.

The daytime running light includes a left daytime running light and a right daytime running light, and the left daytime running light and the right daytime running light are respectively connected to the output terminals of the driving chip.

The daytime running light includes a left position light and a right position light, and the left position light and the right position light are respectively connected to the output terminals of the driving chip.

The input end of the CAN transceiver is connected with the automobile CAN bus.

Both the left position light and the right position light are connected to the output end of the driver chip by hard wires.

In the utility model, after the engine is started, the CAN transceiver sends a signal to the MCU control module, and the MCU control module sends a signal through the drive chip to light the daytime running lights and remind the vehicle ahead in time. When driving at night, turn on the position light switch, the MCU drive module detects the signal, sends a signal to the driver chip to turn off the daytime running light and turn on the position light, reducing or eliminating the potential danger caused by the vehicle to surrounding vehicles and pedestrians, and improving driving safety sex. The utility model extracts the driving system of the daytime running light from other driving modules of the automobile, is applicable to different vehicle types, and is convenient for design adjustment.
