[0004] However, the software version control of the electronic control unit in the prior art only relies on the version number. When the application program is changed but the version number is not updated, the detection result will be inaccurate, the software version will not be controlled, and the assembly of the whole vehicle will be affected. Time-consuming and labor-intensive, especially if the ECU application program has been illegally modified

Embodiment Construction
[0028] As mentioned in the background technology, the software version control of the electronic control unit in the prior art only relies on the version number. When the application program is changed without updating the version number, the detection result will be inaccurate and the software version will not be controlled, which will affect the The assembly of the whole vehicle is time-consuming and labor-intensive; especially when the application program of the electronic control unit is illegally modified.
[0029] The technical scheme of the present invention can realize that after the software of the electronic control unit is updated, the check value calculated by using the check algorithm changes, so that the software change can be detected when comparing with the check value in the background, ensuring that the electronic control unit Effectiveness of software version management.
[0030] In order to make the above objects, features and advantages of the present inve...

The invention discloses an electric control unit software version calibration method, device and a vehicle. The electric control unit software version calibration method comprises the steps that a current calibration value of software loaded to a vehicle electric control unit is detected, and the current calibration value is obtained by executing a calibration algorithm on the software loaded to the vehicle electric control unit; the current calibration value and a background calibration value are compared, and the background calibration value is obtained by executing a calibration algorithm on the developed software after the software of the electric control unit is developed; when the current calibration value is consistent with the background calibration value, calibration is passed. According to the technical scheme, the electric control unit software version control accuracy is improved.
Description
technical field [0001] The invention relates to vehicle control technology, in particular to a method and device for checking the software version of an electronic control unit and a vehicle. Background technique [0002] In the control system of the vehicle, the electronic control unit is referred to as the electronic control unit, the automobile electronic control unit or the integrated circuit control unit, the multi-channel control device, etc., which are composed of integrated circuits and are used to realize a series of functions such as data analysis, processing and transmission. . An application program is usually loaded in the electronic control unit, and under the control of the application program, the normal operation of the electronic control unit is guaranteed. [0003] In the prior art, the ECU software has different versions during the development process. In order to ensure that the vehicle is equipped with the final version of the ECU software, the softwa...
