The invention relates to a BSD power supply management strategy, which is characterized in that an electricity-saving relay is added in a BCM, and conditions are set for opening or closing and BSD system power-on and power-off and function opening logic: a whole vehicle CAN network is awakened, the electricity-saving relay is opened, an angle radar is powered on for self-inspection, and when the angle radar receives information sent by the BCM, the angle radar starts to periodically send messages to a CAN bus, and a DOW alarm function is opened; and after the whole vehicle is powered off, the power-saving relay continuously supplies power to the angle radar until the BCM is dormant or the power-saving relay is turned off without receiving related signals within the set time, and the DOW function is turned off accordingly. According to the technical scheme, the DOW function of the blind spot monitoring system after the whole vehicle is powered off can be realized without changing a program of the blind spot monitoring system based on a network management part. A power supply of the BSD system is connected to a power-saving relay of the BCM, and the DOW function works in different power supply modes of the whole vehicle by making a starting and stopping strategy of the power-saving relay.
本发明涉及一种BSD电源管理策略,在BCM内增加节电继电器并设定条件开启或关闭及BSD系统上下电及功能开启逻辑:整车CAN网络唤醒,节电继电器开启,角雷达上电自检,当角雷达收到BCM发送的信息时,角雷达开始往CAN总线上周期发送报文,DOW报警功能开启;整车下电后,节电继电器持续为角雷达提供电源,直到BCM休眠或节电继电器在设定时间未收到相关信号而关闭,DOW功能随之关闭。本技术方案不需要更改盲点监测系统基于网络管理部分的程序,即可实现其整车下电后DOW功能。将BSD系统的电源接入BCM的节电继电器,通过制定节电继电器的开启关闭策略实现DOW功能在整车不同电源模式下的工作。
