[0027] Example 1

[0028] This application provides a vehicle lighting control system, such as... Figure 1 As shown, the system includes: a power management module 1, an SBC module 2, an MCU module 3, a driver module 4, and an LED module 5; the SBC module 2 is connected to the power management module 1; the MCU module 3 is connected to the SBC module 2; both the power management module 1 and the MCU module 3 are connected to the driver module 4; the LED module 5 is connected to the driver module 4; the SBC module 2 uses the FS2300B series SBC chip.

[0029] In an embodiment, such as Figure 2 As shown, the FCCU1 pin of the SBC chip is connected to the FCCUERR0 pin of the control chip of MCU module 3; the RSTB pin of the SBC chip is connected to the RESET-b pin of the control chip of MCU module 3. The SBC chip is also connected to the control chip of MCU module 3 via the SPI bus.

[0030] Furthermore, the SBC chip model of the FS23 series is MFS2300BMBAOEP. The chip model of MCU module 3 is S32K312 integrated chip.

[0031] In the embodiment, the power management module 1 is a BUCK voltage reduction module.

[0032] Working principle: through the 5V voltage of the SBC module 2, the switch of the power management module 1 is opened, and the BUCK voltage reduction module reduces the voltage of the input power supply signal to supply power to the driving module 4, and at the same time, the SBC module 2 also supplies power to the MCU module 3. The MCU module 3 will transmit the command sent by the vehicle body to the driving module 4 according to the command received by the CAN transceiver in the SBC module 2, and the driving module 4 drives the light emitting module 5 to execute the corresponding action. Through SPI communication, the watchdog of the SBC module 2 is used to monitor the software running level of the MCU module 3, and the window recovery time and the window cycle time are configured. If the MCU module 3 fails to refresh the counter within a predetermined time or fails to refresh, the watchdog of the RSTB end pin will trigger a reset to try to restart the MCU module 3. The FCCU1 end pin in the SBC module 2 is used to monitor the error signal of the MCU module 3, and when the FCCU1 end pin monitors the error, the chip LIMP pin can be configured to be in an effective state to reset the MCU module 3. The FCCU1 end pin monitoring can be configured together with the watchdog, or can be independent of each other. Through the effective reset of the RSTB end, the closing or entering of the function safety state of the driving module 4 caused by the failure of the MCU module 3 is reduced, the abnormal use of the vehicle lamp is avoided, and the system safety and reliability are improved.
