[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It should also be noted that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0022] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art. It will also be understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present invention, and will not be interpreted as having an idealized or overly formal meaning unless explicitly defined as such herein.

[0023] The present invention provides a vehicle electronic controller automatic upgrade method, device, electronic device, computer storage medium and computer program product to improve the efficiency of vehicle ECU upgrade. The method and the device are based on the same concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0024] Figure 1It is a flow chart of the automatic upgrade method of the vehicle electronic controller provided in the embodiment of the present invention. The automatic upgrade method of the vehicle electronic controller provided in the embodiment of the present invention is used for a host computer connected to the vehicle electronic controller. This specification provides method operation steps such as the embodiments or flow charts, but more or fewer operation steps may be included based on conventional or non-creative labor. The order of steps listed in the embodiments is only one way of executing the steps among many orders, and does not represent the only order of execution. When the actual system or server product is executed, it can be executed in the order of the methods shown in the embodiments or the drawings or in parallel (for example, in a parallel processor or multi-threaded processing environment).

[0025] S101: Obtain an upgrade package for the vehicle electronic controller.

[0026] It should be noted that the host computer in the embodiment of the present invention may obtain the upgrade package of the vehicle electronic controller from the server, or may obtain the upgrade package of the vehicle electronic controller manually.

[0027] S102: Confirm whether the host computer is normally connected to the vehicle electronic controller.

[0028] In this step, it is detected whether the host computer is normally connected to the vehicle electronic controller to be upgraded, and if not, an error is reported. In addition, the host computer and the vehicle electronic controller can be connected via Ethernet, for example.

[0029] S103: Transmit the upgrade package to the vehicle electronic controller.

[0030] In this step, the upgrade package in the host computer is transmitted to the vehicle electronic controller to be upgraded. Here, for example, the upgrade package can be transmitted to the specified path of the vehicle electronic controller to be upgraded through the Secure Shell (SSH) protocol.

[0031] S104: Acquire upgrade package information, and select different upgrade instructions based on the upgrade package information to upgrade the vehicle electronic controller.

[0032] This step may further include a series of sub-steps, Figure 2 A schematic diagram of an example of step S104 is shown below. Figure 2 A series of sub-steps of step S104 are described.

[0033] S1041: Before the vehicle electronic controller is upgraded, obtaining software attribute information of the vehicle electronic controller before the upgrade.

[0034] The pre-upgrade software attribute information includes the version number information of the pre-upgrade software of the vehicle electronic controller.

[0035] S1042: Obtain upgrade package information, and determine whether the size of the upgrade package is greater than a preset threshold based on the upgrade package information.

[0036] The upgrade package information includes the upgrade package size information. Based on the upgrade package information, it is determined whether the upgrade package size is greater than a preset threshold. If the upgrade package size is greater than the preset threshold, the process proceeds to step S1043. If the upgrade package size is less than or equal to the preset threshold, the process proceeds to step S1044. The preset threshold can be set to 300M, for example.

[0037] S1043: Use a double-sided upgrade instruction to upgrade the vehicle electronic controller.

[0038] S1044: Use a single-side upgrade instruction to upgrade the vehicle electronic controller.

[0039] The host computer can store double-sided upgrade instructions and single-sided upgrade instructions in advance, respectively, and can determine whether the upgrade package size is greater than a preset threshold based on the upgrade package information to call different upgrade instructions for upgrading. When the upgrade package size is small, the speed of upgrading using the single-sided upgrade instruction is faster and more efficient. Therefore, selecting different upgrade instructions based on the upgrade package information to upgrade the vehicle electronic controller can improve the efficiency of upgrading the vehicle electronic controller.

[0040] S1045: During the process of upgrading the vehicle electronic controller, monitor the upgrading progress of the vehicle electronic controller in real time.

[0041] S1046: After the upgrade is completed, check whether the vehicle electronic controller automatically restarts. If not, restart the vehicle electronic controller.

[0042] After the vehicle electronic controller upgrade is completed through monitoring in step S1045, it is detected whether the vehicle electronic controller automatically restarts. Under normal circumstances, the vehicle electronic controller automatically restarts after the upgrade is completed. If the vehicle electronic controller is not detected to automatically restart, the vehicle electronic controller is restarted by controlling the power supply to power on and off again.

[0043] S1047: After completing the upgrade of the vehicle electronic controller, obtain the upgraded software attribute information of the vehicle electronic controller.

[0044] Likewise, the upgraded software attribute information includes the version number information of the upgraded software of the vehicle electronic controller.

[0045] S1048: Compare the software attribute information before the upgrade and the software attribute information after the upgrade to determine whether the upgrade is successful.

[0046] If the software attribute information before the upgrade is inconsistent with the software attribute information after the upgrade, it means that the upgrade is successful. If the software attribute information before the upgrade is consistent with the software attribute information after the upgrade, it means that the upgrade is unsuccessful. When the upgrade is unsuccessful, a warning message can be issued.

[0047] The example described here includes steps S1041, S1045, S1046, S1047, and S1048, but the present invention is not limited thereto and may not include the above steps or may only include some of the above steps.
