The invention provides an automobile power distribution method, a power distribution system and an automobile, a zone control power distribution module is designed and defined according to an automobile model architecture, resource reservation and combined distribution are performed on a wake-up source according to a principle of proximity of a wire harness, and the wake-up source can be distributed to a zone control unit and also can be distributed to a constant power module; the method is not limited by limited wake-up sources and four power supply modes of a vehicle body control module, a load with a wake-up source is provided with a constant power module and a monitorable bypass power supply at the same time, in a low power consumption mode, the load is powered by the bypass power supply, and when an area control unit detects whether bypass current exceeds a preset threshold value or not, the bypass power supply cuts off power supply. Power is supplied by a constant power supply, and the number of modules working under low power consumption is reduced. According to the invention, aiming at the intelligent power distribution dormancy awakening function of the automobile, the current and subsequent function expansion scene requirements are integrated, and the design of each regional control software and hardware platform is reasonably planned, so that the function requirements of dormancy awakening and regional power distribution in different scene modes are realized.

    本发明方法提供一种汽车配电方法、配电系统和汽车,通过根据车型架构设计定义区控配电模块,将唤醒源根据线束就近原则进行资源预留和组合分配,既可以分配到区控控制单元,也可以分配到常电模块,不再受限于车身控制模块有限的唤醒源及4种电源模式下,同时在带唤醒源的负载配置常电模块,配置可监控的旁路电源,在低功耗模式下,负载由旁路电源供电,当区域控制单元检测所述旁路电流是否超过预设阈值,旁路电源断开供电,由常电电源供电,减少低功耗下工作的模块数量。本发明能够针对汽车智能配电休眠唤醒功能,综合当前及后续功能拓展场景需求,合理规划各区控软硬件平台设计,以实现不同场景模式下休眠唤醒,区域配电的功能需求。
