The invention is suitable for the technical field of driving control, and provides a dormancy awakening control method and system for an automatic driving domain control system, and the method comprises the following steps: when a whole vehicle is powered on, a DCU is awakened through a hard line, charges a capacitor of the DCU, starts to work after being awakened, and awakens a left rear angle millimeter wave radar and a right rear angle millimeter wave radar; the system can work normally; the DCU can directly drive a BSD lamp on the outside rear-view mirror, and detection information of the left rear angle millimeter wave radar and the right rear angle millimeter wave radar is directly transmitted to the DCU; when the whole vehicle is powered off, the DCU is powered off after delaying for 3 minutes, at the moment, the MCU is always powered on, and the system works normally; and when the DCU judges that the power-off time exceeds 3 minutes or the vehicle locking condition is met, the system is powered off. The DCU can directly drive the BSD lamp on the outside rear-view mirror, detection information of the left rear angle millimeter-wave radar and the right rear angle millimeter-wave radar is directly transmitted to the DCU, intermediate forwarding links are reduced, and the control reliability is enhanced.
本发明适用于驾驶控制技术领域,提供了一种自动驾驶域控制系统休眠唤醒控制方法及系统,包括以下步骤:当整车上电时,DCU通过硬线唤醒,给DCU自带的电容充电,唤醒后开始进行工作,DCU唤醒左后角毫米波雷达和右后角毫米波雷达,使得系统正常工作;DCU能够直接驱动外后视镜上的BSD灯,所述左和右后角毫米波雷达的检测信息直接传递给DCU;当整车下电时,DCU延迟3min后下电,此时MCU常电保持导通,系统正常工作;当DCU判断下电时间超过3min或者满足锁车条件后,系统下电。DCU能够直接驱动外后视镜上的BSD灯,左和右后角毫米波雷达的检测信息直接传递给DCU,减少中间转发环节,增强控制的可靠性。
