The invention discloses a vehicle body control method and a vehicle body controller, and the method comprises the steps: receiving a program updating instruction sent by a client through a wireless communication module in the vehicle body controller, setting a reprogramming flag bit to be valid, copying application data stored in a second partition to a third partition for backup, and after the backup is completed, storing the application data in the third partition; and receiving the upgrading data sent by the client through the wireless communication module, and storing the upgrading data to the second partition, thereby realizing the program updating of the vehicle body controller. According to the embodiment of the invention, the remote program updating of the vehicle body controller can be realized, compared with a technical engineer carrying an upgrading tool to carry out field updating, the consumed manpower and time are less, and in addition, when the program is updated, the third partition is firstly used for backing up the application data previously stored in the second partition, so that the program updating efficiency is improved. Even if the program fails to be updated, the original application execution code can still be obtained, so that the normal operation of the vehicle body controller can be ensured.
本申请公开了一种车身控制方法和车身控制器,在通过车身控制器中的无线通信模块接收客户端发送的程序更新指令,将重编程标志位设置为有效,将第二分区中存储的应用数据拷贝到第三分区进行备份,在备份完成后,通过无线通信模块接收客户端发送的升级数据,并将升级数据存储至第二分区,从而实现对车身控制器的程序更新。根据本申请实施例,可以实现对车身控制器的远程程序更新,相比于技术工程师携带升级工具进行现场更新,消耗的人力和时间更少,而且,本实施例中在程序更新时,先利用第三分区对第二分区内之前存储的应用数据进行备份,如此,即使程序更新失败,仍然可以获取到原来的应用执行代码,从而保证车身控制器可以正常运行。
