The output end of the vehicle controller is connected to the input end of the microcontroller (MCU); the microcontroller (MCU) is respectively connected to the system-on-chip (SOC) and the printed circuit board (PCB).

9. A control system for preventing an intelligent driving controller from overheating and failure as claimed in claim 8, characterized in that: The vehicle controller inputs information on whether the vehicle is in a startup state and whether the gear position of the vehicle is a parking gear to the microcontroller (MCU); the system-on-chip (SOC) inputs temperature information of the system-on-chip (SOC) to the microcontroller (MCU); the printed circuit board (PCB) inputs temperature information of the printed circuit board (PCB) to the microcontroller (MCU).

10. A control system for preventing an intelligent driving controller from overheating and failure as claimed in claim 9, characterized in that: The microcontroller (MCU) controls powering off and on of the system-on-chip (SOC) according to information on whether the vehicle is in a starting state and whether the gear position of the vehicle is a parking gear input by the vehicle controller, temperature information of the system-on-chip (SOC) input by the system-on-chip (SOC), and temperature information of the printed circuit board (PCB) input by the printed circuit board (PCB).
