The embodiment of the invention provides a controller upgrading method and system. The method comprises the steps that the TBOX detects whether a whole vehicle is in a high-voltage state or not; if the TBOX detects that the whole vehicle is in the high-voltage state, the TBOX sends a first upgrade package to the BCM, sends a second upgrade package to the BMS and sends a third upgrade package to the DCDC; the first operation partition keeps outputting ignition signals to the BMS and the DCDC, and the first backup partition is provided with the first upgrade package; the second operation partition keeps high-voltage output to the DCDC, and the second backup partition is provided with the second upgrade package; the third operation partition is enabled and keeps a high-voltage direct current to low-voltage direct current state, and the third upgrade package is installed in the third backup partition. According to the embodiment of the invention, the phenomenon that the storage battery generates electricity when the controller is upgraded under a low-voltage condition is avoided so that the controller is successfully upgraded.
本发明实施例提供了一种控制器升级方法和系统。该方法包括:TBOX检测整车是否处于高压状态;TBOX若检测出整车处于高压状态,向BCM发送第一升级包、向BMS发送第二升级包,并向DCDC发送第三升级包;第一运行分区保持向BMS和DCDC输出点火信号,第一备份分区安装第一升级包;第二运行分区向DCDC保持高压电输出,第二备份分区安装第二升级包;第三运行分区保持使能,保持高压直流转低压直流状态,第三备份分区安装第三升级包。本发明实施例避免了在低压条件下对控制器进行升级时造成的蓄电池溃电现象,从而使得控制器升级成功。
