The invention discloses a load control circuit and a vehicle. The circuit comprises a power management integrated circuit, a microcontroller, a signal processing circuit, a driving chip and a power supply, the power management integrated circuit monitors the microcontroller, outputs a fault signal or a fault-free signal to the signal processing circuit, and outputs a fault signal to the signal processing circuit at least when the microcontroller is abnormal or reset; the microcontroller is used for outputting a control signal to the control end of the driving chip; the signal processing circuit is used for outputting a limp signal to the driving chip at least when the power management integrated circuit outputs the fault signal; and the driving chip outputs a starting signal or a closing signal to the load, and when the receiving signal processing circuit sends the limping signal, the driving chip is in a limping mode and outputs the starting signal to the load. According to the invention, when the microcontroller is abnormal or reset, the driving chip is forced to keep output, the safety of vehicle driving and the user experience are improved, and the casualty risk is reduced.
