[0035] Example 1

[0036] The embodiment of the present application provides a control system for a vehicle position light, comprising: a controller 1 and a position light 2 connected to the controller 1; the controller 1 comprises: a power module 11, an SBC module 12, an MCU module 13, a first communication module 14 and a motor drive module 15; the SBC module 12 and the motor drive module 15 are both connected to the power module 11; the SBC module 12, the first communication module 14 and the motor drive module 15 are all connected to the MCU module 13; the position light 2 comprises a second communication module 21, a headlight drive module 22, a motor 23 and a lamp body 24; the first communication module 14 and the headlight drive module 22 are both connected to the second communication module 21; the motor drive module 15 is connected to the motor 23; the power module 11 is connected to the headlight drive module 22; the headlight drive module 22 and the motor 23 are both connected to the lamp body 24.

[0037] The power module 11 is used to supply power to each module. The SBC module 12 is used to receive the vehicle body signal and transmit the vehicle body signal to the MCU module 13. The MCU module 13 processes the vehicle body signal to generate a light control signal and a motor 23 control signal. The MCU module 13 transmits the light control signal to the first communication module 14, and transmits the light control signal to the second communication module 21 via the first communication module 14. The second communication module 21 transmits the light control signal to the headlight driving module 22. The headlight driving module 22 controls the light effect of the lamp body 24 according to the light control signal. At the same time, the MCU module 13 also transmits the motor 23 control signal to the motor driving module 15, and drives the motor 23 to operate via the motor driving module 15, thereby controlling the lighting angle of the lamp, providing richer and more diverse headlight animation effects and light show effects.

[0038] It should be noted that the SBC module 12 receives vehicle body signals, which include light control signals and vehicle current status signals. The MCU processes the vehicle body signals. Only when the vehicle current status signal is the vehicle stopped state, will it simultaneously generate light control signals and motor 23 control signals to achieve rich and diverse light animation effects and light show effects to ensure driving safety. When the MCU processes the vehicle body signal and detects that the vehicle current status signal switches from the stopped state to the running state, or the light control signal is the position light function, the MCU module 13 controls the lamp body 24 to the default state to ensure that the position light 2 function can be used normally during driving to ensure the safety of the driving lights.

[0039] In an embodiment, the SBC module 12 includes an SBC chip, such as CY329, which integrates a permanent power supply system (PSS) or a non-permanent power supply system (NPSS) with or without CAN wake-up, a VPR step-up / step-down regulator (3V), two 5V linear regulators, three independent 5V sensor power supplies, a power stage with integrated clamping and diagnostic functions (7 times low side, 1 times high side), a CAN-FD transceiver, an MSC microsecond bus, four 32-bit stop counters, a 3-level watchdog, etc. The SBC module 12 can also provide 5V power supply to the MCU module 13, the first communication module 14, and the second communication module 21. The SAB module 12 obtains the vehicle body signal through the built-in CAN-FD transceiver.

[0040] In the embodiment, the lamp body 24 includes a driving gear 241 and an LED light-emitting module 242; the motor 23 is connected to the driving gear 241; and the headlight driving module 22 is connected to the LED light-emitting module 242. Further, the motor 23 controls the driving gear 241 based on the motor 23 control signal, and controls the rotation and movement of the lamp through the driving gear 241, such as controlling the light-emitting angle of the lamp to face the ground or controlling the lamp to rotate left and right; the headlight driving module 22 drives the LED light-emitting module 242 to perform corresponding lighting effects based on the light control signal, such as the running light effect or the breathing light effect, etc.

[0041] In the embodiment, the first communication module 14 and the second communication module 21 are both CAN communication modules, and the CAN communication modules are used to ensure that the lighting control signal can be effectively, quickly and accurately transmitted.

[0042] In the embodiment, the power module 11 includes: a protection unit 111, a constant voltage driving unit 112 and a high-side driving unit 113;

[0043] The input end of the protection unit 111 is connected to the power supply end of the vehicle body; the constant voltage drive unit 112, the high side drive unit 113 and the SBC module 12 are all connected to the output end of the protection unit 111; the constant voltage drive unit 112 is connected to the headlight drive module 22; the high side drive unit 113 is connected to the motor drive module 15.

[0044] The protection unit 111 is used to protect the power signal input from the vehicle body power supply end, the constant voltage drive unit 112 performs constant voltage processing on the power signal after the protection output to power the headlight drive module 22, and the high-side drive unit 113 performs voltage stabilization processing on the power signal after the protection output to power the motor 23.

[0045] In the embodiment, the vehicle light driving module 22 is a linear chip driving module, and the LED light emitting module 242 is controlled by the output channel of the linear chip in the linear chip driving module to achieve different lighting effects.

[0046] In the embodiment, the LED light emitting module 242 includes a plurality of lamp beads, which are OLED lamp beads. The OLED lamp beads have good display texture and high animation fineness. Compared with LED lamp beads, the OLED lamp beads have a high contrast ratio and a fast response time.
