The invention discloses a vehicle FOTA upgrading system and method based on feed protection, and the system comprises an electrical parameter obtaining module which is at least used for obtaining the electrical parameters of an external power supply, and the electrical parameters comprise voltage, current and electrical frequency; the feed protection module is at least used for monitoring the feed state of an external power supply based on the electrical parameters and sending the feed state to the upgrade control module; and the upgrading control module is at least used for controlling the FOTA upgrading of the vehicle based on the feed state. The problem of abnormal feed of the external power supply in the FOTA upgrading process is solved, the vehicle system can be protected from being influenced by the abnormal feed of the external power supply, original software does not need to be completely backed up, and the cost and complexity of the vehicle are reduced.
一种基于馈电防护的车辆FOTA升级系统及方法,所述车辆FOTA升级系统包括电参数获取模块,至少用于获取外部电源的电参数,所述电参数包括电压、电流和电频率;馈电防护模块,至少用于基于所述电参数监测外部电源的馈电状态,并将所述馈电状态发送至升级控制模块;升级控制模块,至少用于基于所述馈电状态控制车辆FOTA升级。本发明解决了FOTA升级过程中外部电源出现异常馈电的问题,可以保护车辆系统免受来自外部电源的异常馈电影响,无需对原始软件进行完整备份,降低了车辆的成本和复杂性。
