| 摘 要： | 为合理应用车载低压电能,文章设计了基于应用场景识别的一体化分层唤醒、休眠控制的策略。根据KL30下整车有效唤醒状态按需唤醒电控单元,并引入用车场景预测、提前唤醒电控单元,解决电控单元按需唤醒下用车场景快速切换带来的响应延迟问题;同时,通过场景识别进一步排查无法休眠的电控单元,进行防低压亏电控制。文章应用CANOE?工具仿真了用户遥控解充电枪锁操作及充电口单元无法休眠工况,结果表明,所提出的控制策略能够提高解充电枪锁响应速度,并能够识别出无法休眠电控单元进行防亏电控制。

| Abstract: | In order to save 12V power,wakeup&sleep mechanism is designed by use case recognition.After use case recognition and user intention prediction according to the running wakeup resource and user action,only related ECUs will be waked up.Moreover,ECUs that cannot sleep in time will be marked and measures will be taken to prevent 12V battery drainage.Door operating condition and illegal wakeup condition of a model car was simulated by CANOE,to validate the control strategy in energy saving and battery drainage prevention,accordingly. |
