在本申请的具体实施例中,当整个车控域控制器处于休眠状态时,电源管理模块21接收到唤醒信号(KL15、制动信号、CAN唤醒信号1),微处理器模块22正常启动,完成初始化,微处理器模块22识别唤醒源和唤醒场景,微处理器模块22判断是否需要唤醒主控处理模块32,如果需要唤醒,则通过控制信号a3唤醒主控处理模块32,主控处理模块32正常启动;同样地,微处理器模块22判断是否需要唤醒行车控制处理模块42,如果需要唤醒,则通过控制信号a2唤醒行车控制处理模块42,行车控制处理模块42正常启动;同样的,微处理器模块22判断是否需要唤醒泊车控制处理模块52,如果需要唤醒,则通过
控制信号a1唤醒泊车控制处理模块52,泊车控制处理模块52正常启动。
在本申请的具体实施例中,当整个车控域控制器处于休眠状态时,主控处理模块32接收到唤醒信号(OBD Activeline、CAN唤醒信号2~n、以太网唤醒信号1~n、RTC定时唤醒信号),主控处理模块32通过控制信号b3唤醒电源管理单元321,主控处理模块32识别唤醒源和唤醒场景,主控处理模块32判断是否需要唤醒微处理器模块22,如果需要唤醒,则通过控制信号b3唤醒微处理器模块22,微处理器模块22正常启动;同样地,主控处理模块32判断是否需要唤醒行车控制处理模块42,如果需要唤醒,则通过控制信号b1唤醒行车控制处理模块42,行车控制处理模块42正常启动;同样的,主控处理模块32判断是否需要唤醒泊车控制处理模块52,如果需要唤醒,则通过控制信号b2唤醒泊车控制处理模块52,泊车控制处理模块52正常启动。
上述实施例中,该方案支持不同的唤醒场景识别,若个别简单的唤醒场景只需要单个处理器模块进行处理,则只有相关的处理模块正常上电工作,例如微处理器模块22单独上电工作或主控处理模块32单独上电工作时,控制器供电系统工作于低功耗模式;该方案也支持复杂的唤醒场景,多个处理器模块协同工作的情况,以实现更复杂的工作场景处理功能。该方案有目的性的控制每个处理器单元的供电,实现了多个唤醒场景要求的功能,能灵活控制整个融合车控域控制器的功耗。
本申请实施例提出的控制器供电系统包括电源输入电路、微处理器电路、主控处理电路、行车处理电路、唤醒电路和泊车处理电路;其中,电源输入电路包括:第一电源输入电路和第二电源输入电路;第一电源输入电路和第二电源输入电路互为备份,共同为微处理器电路、主控处理电路、行车处理电路和泊车处理电路提供供电。当一个电源输入电路发生故障时,另外一个电源输入电路可以继续为该系统提供供电,从而可以保证高性能处理器芯片内部的不同处理域之间供电的独立性,可灵活启用低功耗模式,可提高系统鲁棒性,可避免受MCU域和CPU域子系统的单点故障的干扰,当MCU域作为系统的安全监控时可以提高系统的功能安全等级。本申请实施例提出的控制器供电系统,可以支持双路电源的冗余供电,且实现两路电源的隔离,并具备对两路电源的过压、欠压、过流、过温的诊断与保护功能,当MCU域作为系统的安全监控时,能够提高系统的功能安全等级;并且,本申请实施例的技术方案实现简单方便、便于普及,适用范围更广。
