The invention relates to a multifunctional wake-up circuit, an electronic control system and a vehicle, the multifunctional wake-up circuit comprises an ignition wake-up module, a communication wake-up module and a switch wake-up module which are connected with a power supply module, the ignition wake-up module is used for outputting an enable signal to the power supply module to supply power to a main controller when receiving a manual ignition signal, and the communication wake-up module is used for outputting a communication wake-up signal to the switch wake-up module when receiving a manual ignition signal. Enabling the main controller to execute an action corresponding to the manual ignition signal; the communication awakening module is used for awakening the power supply module to supply power to the main controller when the CAN bus recognizes an awakening signal, so that the main controller executes an action corresponding to the awakening signal; and the switch awakening module is used for supplying power to the main controller through a corresponding high-level signal output by the resistance network when the awakening switch is triggered, so that the main controller executes an action corresponding to the corresponding high-level signal. Therefore, the problem that a plurality of wake-up functions cannot be compatible and integrated well in a current controller scheme is solved, and multifunctional wake-up of the circuit is realized.

    本申请涉及一种多功能唤醒电路、电子控制系统及车辆,多功能唤醒电路包括:与电源模块相连的点火唤醒模块、通信唤醒模块和开关唤醒模块,其中,点火唤醒模块用于在接收到手动点火信号时,输出使能信号至电源模块为主控制器供电,使得主控制器执行与手动点火信号对应的动作;通信唤醒模块用于在CAN总线识别到唤醒信号时,唤醒电源模块为主控制器供电,使得主控制器执行与唤醒信号对应的动作;开关唤醒模块用于在唤醒开关被触发时,通过电阻网络输出的相应的高电平信号为主控制器供电,使得主控制器执行与相应的高电平信号对应的动作。由此,解决了当前控制器方案无法很好地对多个唤醒功能进行兼容集成的问题,实现电路的多功能唤醒。
