Embodiment 1

[0036] This embodiment provides a method for refreshing the power window calibration file, which is applied to the vehicle body control module, such as figure 1 shown, including the following steps:

[0037] S101. Receive a refresh instruction, where the refresh instruction includes a storage path of a new calibration file in a refresh device and an identifier of the new calibration file.

[0038] Wherein, the refresh command is generated and sent by the refresh device according to the instruction of the user, and the refresh device communicates with the body control module through the CAN diagnosis port of the body control module. The identifier of the new calibration file can be used to distinguish the new calibration file from other files. The refreshing device is a host computer including DPS software.

[0039] S102. Search and download the new calibration file in the refresh device according to the storage path and the identifier.

[0040] In this step, if only one new...

Embodiment 2

[0049] This embodiment provides another method for refreshing the power window calibration file, which can be applied to the body control module, such as figure 2 shown, including the following steps:

[0050] S201. Receive a refresh instruction, where the refresh instruction includes a storage path of a new calibration file in a refresh device and an identifier of the new calibration file.

[0051] S202. Search for the new calibration file in the refreshing device according to the storage path and the identification, and according to the corresponding relationship between the identification and the position of the electric window, according to the left front window, the right front window, the left rear window and the right Download the new calibration files sequentially in the order of the rear windows. Downloading and storing in a certain order can facilitate the identification of new calibration files by the body control module.

[0052] S203. Determine a target storage...

Embodiment 3

[0065] This embodiment provides another method for refreshing the power window calibration file, which can be applied to the vehicle body control module, such as image 3 shown, including the following steps:

[0066] S301. Receive a refresh instruction, where the refresh instruction includes a storage path of a new calibration file in a refresh device and an identifier of the new calibration file.

[0067] S302. Search for the new calibration file in the refresh device according to the storage path and the identification, and according to the corresponding relationship between the identification and the position of the electric window, according to the left front window, the right front window, the left rear window and the right Download the new calibration files sequentially in the order of the rear windows.

[0068] S303. After the new calibration file is completely stored in the target storage address, determine the target power window module corresponding to the target s...

Abstract

The present invention provides a method for refreshing a power window calibration file, a storage medium, and a vehicle body control module, wherein the refreshing method includes: receiving a refresh instruction, the refresh instruction including a storage path of a new calibration file in a refresh device and an identification of the new calibration file; Find and download the new calibration file according to the storage path and identification; determine the target storage address corresponding to the identification of the new calibration file in the body control module according to the corresponding relationship between the identification and the storage address, and store the new calibration file under the target storage address ; After the refresh program is triggered, according to the corresponding relationship between the storage address and the power window module, send a query command to the target power window module corresponding to the target storage address; receive the refresh status information fed back by the target power window module in response to the query command , the refresh state information indicates that the calibration file is not refreshed and the new calibration file is sent to the target electric window module. The above method can simplify the refreshing process of the power window calibration file.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a method for refreshing an electric window calibration file, a storage medium and a vehicle body control module. Background technique [0002] With the development of automobiles in the direction of electronic control, most parts on the body have realized flexible electronic control, such as windows and lights. The control of the car window is electronically controlled through the electric window module and the body control module. The electric window module and the body control module are connected through the Lin bus. The body control module generates operation instructions according to the user's operation and sends them to the corresponding electric vehicle The window module, and the electric window module performs corresponding operations on the windows it controls according to the operation instructions. Usually, the window calibration file is stored in the electric w...
