Vehicle light over-temperature protection system and vehicle with the same, and vehicle light over-temperature protection method

The invention provides a vehicle light over-temperature protection system and a vehicle with the same, and a vehicle light over-temperature protection method. The system includes multiple PTC temperature detection modules which are connected with multiple grille lights and are used for detecting the temperature of the corresponding grille lights and obtaining a temperature signal, an MCU chip which is capable of determining whether the temperature signal surpasses the threshold and sending a feedback signal if the threshold is surpassed, a host computer capable of receiving the feedback signaland notifying a vehicle driver, an LED driving chip which is connected with the MCU chip and the multiple grille lights and is capable of receiving the feedback signal and adjusting the current of the multiple grille lights, and a power source module capable of supplying power to the MCU chip and the LED driving chip. The system is advantaged in that the temperature of the grille lights can be timely adjusted, faults due to the over-high temperature of the lights can be avoided, and driving safety of vehicles is guaranteed.
