The invention discloses a method for reducing the quiescent current of a vehicle controller. The method comprises the steps that S1, a whole vehicle power supply is turned off; s2, other controllers, except the domain controller, of the vehicle enter dormancy; s3, after the controllers except the domain controller enter the dormancy state and before the domain controller enters the dormancy state, power supplies of all the controllers controlled by the domain controller are turned off, and then the domain controller enters the dormancy state; meanwhile, power supply of the wake-up control module is reserved; s4, when related functions need to be executed, the whole vehicle network is awakened through an awakening control module, and after the domain controller is awakened, power output to the controller is recovered; and if no function-related controller wakes up the whole vehicle network, the whole vehicle controller of the vehicle continues to enter the dormancy state. According to the method, after the vehicle power supply is turned off, the quiescent current is effectively reduced, and the number of parking days of the vehicle is prolonged; and under the condition that the weight and the cost of the whole vehicle are not increased, the service life of the storage battery is prolonged.

    本发明公开了降低车辆控制器静态电流的方法,S1:车辆整车电源关闭;S2:车辆的除域控制器以外的其他控制器进入休眠;S3:在除域控制器外的控制器进入休眠后,在域控制器自身进入休眠前,关闭受域控制器控制的所有控制器的电源,然后域控制器进入休眠;同时保留唤醒控制模块的供电;S4:当有相关功能需要被执行,通过唤醒控制模块将会唤醒整车网络,域控制器被唤醒后,恢复对前述中的控制器的电源输出;如果没有功能相关控制器唤醒整车网络,则车辆的整车控制器继续进入休眠。本发明的方法,在车辆电源关闭后,有效降低静态电流,延长车辆的停放天数;且在不增加整车重量和整车成本的情况下,延长蓄电瓶的使用时间。
