The invention relates to the technical field of driving assistance control, in particular to a power circuit of an intelligent driving assistance system, the intelligent driving assistance system and a vehicle. The intelligent driving assistance system comprises a first processor and a second processor which are redundant to each other; the power supply circuit of the intelligent driving assistance system comprises a first power supply sub-circuit, a second power supply sub-circuit, a first power supply management integrated circuit, a second power supply management integrated circuit and a third power supply management integrated circuit, the first power supply sub-circuit and the second power supply sub-circuit are independently arranged and serve as redundant power supplies, and the first power supply sub-circuit is connected with the first power supply management integrated circuit and the third power supply management integrated circuit. The power supply supplies power to the first processor and the load. And the second power supply sub-circuit is respectively connected with the second power supply management integrated circuit and the third power supply management integrated circuit and is used for supplying power to the second processor and the load. Therefore, the problem that the overall controller fails due to the fact that the power supply or the load is cut off when the power supply is abnormal and failure of internal circuits and devices is ignored in the prior art is solved.

    本申请涉及驾驶辅助控制技术领域,特别涉及一种智能驾驶辅助系统的电源电路、智能驾驶辅助系统及车辆,其中,智能驾驶辅助系统包括互为冗余的第一处理器和第二处理器,智能驾驶辅助系统的电源电路包括:相互独立设置且互为冗余电源的第一电源子电路和第二电源子电路、第一至第三电源管理集成电路,其中,第一电源子电路分别与第一电源管理集成电路和第三电源管理集成电路相连,用于给第一处理器和负载供电;第二电源子电路分别与第二电源管理集成电路和第三电源管理集成电路相连,用于给第二处理器和负载供电。由此,解决了相关技术在电源异常时切断供电电源或负载,忽略了内部线路和器件失效会导致整体控制器失效的问题。
