Abstract
The invention proposes a kind of onboard system firmware on line upgrading methods, it include: that upgrade file solution is depressed under onboard system more new directory by movable storage device, system compares the version information of upgrade file and current system under more new directory, MD5 verification is carried out to upgrade file if version information is different, teaching and research achievement, then tab file is generated under more new directory, enter upgrade mode when system reboot if detecting tab file, system judges whether to upgrade successfully after upgrading, tab file is deleted if success, upgrade again if failure, enter if still failing and restores factory mode, the present invention provides a kind of more simple and effective firmware upgrade mode of onboard system, the problem of Defective vehicle recall caused by can be effectively reduced because of the system failure and maintenance, improve user experience, reduce automobile production enterprise Pressure.
Description
Technical field
The present invention relates to automotive system upgrade technique field more particularly to a kind of onboard system firmware on line upgrading methods.
Background technique
With the development trend of vehicle intellectualized net connectionization, the technological progress of car networking brings answering for automobile software systems
Miscellaneous degree is continuously increased, and the speed for upgrading iteration is getting faster, and the unstability risk of software is inevitable.Statistical data shows,
More than half Defective vehicle recall of Vehicles Collected from Market is as caused by software defect, this following ratio will likely reach 70%.
In view of the above-mentioned problems, the firmware on line upgrading technology of current country's mainstream, is all the OTA technical foundation for using for reference mobile phone
The function of progress is improved, however this upgrading mode considers insufficient, the upgrading nothing of onboard system to the application scenarios of onboard system
Method directly relies on mobile wireless network or cable network to be upgraded, therefore and its it is inconvenient, pass through wireless network if wanting to have
Or the ability that cable network is upgraded then needs to be updated hardware device upgrading.
Summary of the invention
In view of this, the invention proposes it is a kind of from save hardware resource angle, for onboard system in stabilization
The requirement of property, safety, high efficiency and flexibility etc., a kind of onboard system firmware on line upgrading method of proposition.
The technical scheme of the present invention is realized as follows: the present invention provides a kind of onboard system firmware on line upgrading sides
Method, comprising:
S10, upgrade file solution is depressed under onboard system more new directory by movable storage device；
The version information of S20, the upgrade file under onboard system comparison more new directory and current system, if version information
It is different, execute S30；
S30, MD5 verification is carried out to subregion upgrade file each under more new directory, after verification, is generated under more new directory
Tab file；
S40, when system restarting when, system detection whether there is tab file, enter if detecting tab file
Upgrade mode carries out firmware upgrade to each subregion；
S50, upgrading finish, and system judges whether to upgrade successfully, if upgrading successfully, deletes tab file, and to upgrading
Subregion execute installation script.
On the basis of above technical scheme, it is preferred that further include:
If S60, upgrading failure, judge whether to upgrade failure for the first time, if then repeating step S40, and judge whether to rise
Grade success, if failure, and be not to fail for the first time, then tab file is deleted, into recovery factory mode.
On the basis of above technical scheme, it is preferred that the movable storage device include USB flash disk, mobile hard disk, CD and
Mobile phone.
On the basis of above technical scheme, it is preferred that the upgrade mode includes: flashburn tools according to upgrade file pair
Each subregion carries out programming upgrading.
Still more preferably, the S30 further include:
If S31, not passing through verification, system prompt user verifies failure and simultaneously deletes all upgrade files.
On the basis of above technical scheme, it is preferred that the S50 further include:
S51, multiple upgradings if it exists subregion, then execute installation script subregion sequence successively are as follows: system, spsdk,
sdlapp、qtweb。
A kind of onboard system firmware on line upgrading method of the invention has the advantages that compared with the existing technology
Onboard system firmware on line upgrading method of the invention overcomes asking for conventional onboard system firmware upgrade inconvenience
Topic, can carry out firmware upgrade by movable storage device, carry out being confirmed whether it is correct upgrading by version information comparison
File is confirmed whether upgrade file is correct file by MD5 verification, this method can also in install failure for the first time into
Row upgrades again, if factory reset still if install failure for the second time, avoids install failure that from can not restoring to cause to user
Puzzlement, the present invention can overcome at present because of Defective vehicle recall caused by system defect, improve user experience, reduce the city of Automobile Enterprises
Field pressure, increases automotive system fault-tolerance.
