To this end, an aspect of the present application provides a method for estimating an upgrade duration. Referring specifically to fig. 1, fig. 1 is a flowchart illustrating a method for estimating an upgrade duration according to an exemplary embodiment of the present application.

The estimation method is applied to the cloud, and the estimation method at least comprises S110 to S130, which are described in detail as follows:

s110: and receiving an upgrading request carrying the number of the upgrading part sent by the vehicle end.

The number of the upgrade part is used for representing the identity information of the upgrade part, and each upgrade part is correspondingly provided with a unique number. The number of the upgrade parts in this embodiment may be plural, and the number of the upgrade parts is not limited in this embodiment.

The upgrade request is a request sent by the vehicle end for desiring to upgrade a specified upgrade part.

The vehicle end sends the upgrading request to the cloud end, and the cloud end responds to the upgrading request to carry out the following detection steps.

S120: detecting whether the upgrading request carries other information corresponding to the upgrading part; wherein the other information comprises at least one of a hardware version corresponding to the upgrade part, a current software version and a target upgrade software version.

Other information can characterize the status information of the designated upgraded parts. The number of information in the other information of the present application may be plural, for example, the hardware information and the current software version corresponding to the designated upgrade part. For example, the current software version and the target upgrade software version corresponding to the upgrade part are specified.

s140: if no other information is detected to be carried, the preset upgrading duration is used as the target upgrading duration and is sent to the vehicle end; the preset upgrading time length is from a preset historical upgrading time length table.

If other information is not carried, the characterization cloud only receives the serial numbers of the upgrade parts, and it is difficult to determine the accurate upgrade time according to the single serial numbers. Therefore, the preset upgrade time of the spam is introduced in the embodiment, and is an estimated time set in advance by operation and maintenance personnel, so that the preset upgrade time of one spam can be fed back to the vehicle end under the condition that relevant matching parameters of the upgrade part are missing.

If the cloud end has the number of the upgrade part, the hardware version, the current software version and the upgrade duration average_upgrade_period corresponding to the vehicle end, the upgrade duration of the upgrade table is updated by averaging: average_upgrade_period= (original average_upgrade_period) +new_upgrade_period ]/count number of vehicles.

Illustratively, the cloud stores historical data as shown in table 2, and table 2 is a cloud historical data table. The fed back upgrade information is successfully matched with the second row of data in table 2, the historical upgrade duration in the row of data is 100 (i.e. the target upgrade duration in this embodiment), if the actual upgrade duration fed back is 110, the average upgrade duration= (100+110)/2=105, and the historical upgrade duration in the row of table 2 is updated to 105.

TABLE 2

If the cloud does not have the number of the upgrade part, the hardware version, the current software version and the upgrade duration average_upgrade_period corresponding to the vehicle end, the new_upgrade_period (actual upgrade duration) reported by the vehicle end is directly inserted as the average_upgrade_period (historical upgrade duration).

If the matching between the upgrade information fed back by the vehicle end and the information stored in the cloud end fails, the cloud end is characterized in that the upgrade information is not stored, namely, the historical upgrade time corresponding to the corresponding upgrade part is not stored. The actual upgrading time length in the upgrading information and other information in the upgrading information are further entered into the above table 2 (the information in table 2 is the preset matching information in the embodiment), that is, the preset matching information is newly added in table 2: the serial numbers of the upgrade parts, the hardware version, the current software version, the target software version, the historical upgrade duration and the statistics vehicle number are respectively filled in. Since the upgrade information is new preset matching information and the number of front vehicles is not counted, the number of counted vehicles corresponding to the new data in table 2 is 1.

The embodiment provides a mode of newly adding preset matching information, if matching failure of the upgrading information and the existing preset matching information is detected, the upgrading information is directly stored to a cloud as the new preset matching information, and the actual upgrading duration in the upgrading information is used as the historical upgrading duration corresponding to the new preset matching information.

It is noted that, in the traversal process, if the matching information corresponding to the target upgrading part fails to match with the preset matching information, the preset duration of the spam corresponding to the target upgrading part is used as the historical upgrading duration of the spam and is fed back to the vehicle end.

According to the embodiment, the matching operation is performed on the matching information corresponding to each upgrading part in an endless manner in a traversing manner of each upgrading part, so that the historical upgrading duration corresponding to each upgrading part is accurately determined.
