The embodiment of the invention discloses a vehicle controller program security updating method and device, equipment and a medium. The method comprises the following steps: determining whether a safe starting function of a target vehicle controller is started or not, verifying an application program and calibration data of the target vehicle controller, and determining a data verification result; determining whether the bootstrap program is valid or not according to the starting result of the safe starting function of the target vehicle controller, and updating the invalid bootstrap program; and according to the data verification result, determining a re-editing request flag bit state, and according to the re-editing request flag bit state, carrying out security updating on an application program and calibration data of a target vehicle controller. By adopting the technical scheme, the safe updating of the application program and the calibration data, the safe starting of the vehicle controller and the updating of the guide program are realized, and the program updating safety of the vehicle controller, the starting safety of the vehicle controller and the updating convenience of the guide program of the vehicle controller are improved.

    本发明实施例公开了一种车辆控制器程序安全更新方法、装置、设备及介质。该方法包括:确定目标车辆控制器的安全启动功能是否开启,并对目标车辆控制器的应用程序以及标定数据进行校验,确定数据校验结果;依据目标车辆控制器的安全启动功能开启结果确定引导程序是否有效,并对无效的引导程序进行更新;依据所述数据校验结果确定重编辑请求标志位状态,并依据所述重编辑请求标志位状态对目标车辆控制器的应用程序以及标定数据进行安全更新。采用本技术方案,实现了对应用程序和标定数据的安全更新、车辆控制器安全启动以及引导程序更新,提升了车辆控制器程序更新的安全性、车辆控制器启动的安全性以及对车辆控制器引导程序更新的便捷性。
