Description
Technical field
The present invention relates to field of automobile control, and in particular to a kind of cloud that is based on to vehicle electronic control unit system liter
The method of grade.
Background technique
Electronic control unit, English name are Electronic Control Unit, abbreviation ECU, also known as vehicle-mounted computer.
Vehicle electronic control unit (abbreviation ECU) is function element particularly important on automobile, after automobile factory, with
The progress of vehicular manufacturer and the research and development of auto parts and components manufactory, can constantly survey the function of vehicle electronic control unit
Examination, and carry out system upgrade.Currently, vehicle electronic control unit can only support two kinds of upgrade modes: first is that local upgrade, even if
Software upgrading is realized after being connected with burning chip tool to ECU burning mouth；Second is that online upgrading, i.e., communicate work using CAN/LIN
Tool is connected to automobile cabin diagnostics port and realizes software upgrading.ECU is caused to avoid upgrading link error from leading to upgrading failure
It can not work, both upgrade modes can only all be operated by professional, be usually to notify user that vehicle is reached the shop 4S, by 4S
The professional in shop upgrades the vehicle electronic control unit of vehicle, thus will lead to a large amount of vehicle aggregations shop 4S, both stops over use
The time at family, and increase the workload of the shop 4S staff, inconvenience is brought to user and the shop 4S.For a long time, how to make
User in time, easily can be upgraded always still unsolved hang-up to vehicle electronic control unit.
Summary of the invention
The purpose of the present invention is in view of the deficiencies of the prior art, establish one kind based on cloud to vehicle electronic control unit
The method of system upgrade, no matter vehicle anywhere, user can be by internet voluntarily to the electronics control of personal vehicles
Unit processed carries out system upgrade, provides low price, convenient way for the quick response of exploitation, the upgrading of electronic control unit,
Vehicle electronic control unit system upgrade cost is reduced, user experience is improved.
The object of the present invention is achieved like this: it is a kind of based on cloud to the side of vehicle electronic control unit system upgrade
Method, comprising the following steps:
1) automobile intelligent upgrading software library is established in cloud；
2) registration logs in personal account on the app software of intelligent terminal；
3) cloud sends the system upgrade information of personal vehicles under the account to personal account, and intelligent terminal user is in intelligence
Corresponding personal vehicles information under personal account is chosen in the list of the app software of energy terminal device, and confirms upgrading；
4) intelligent terminal downloads corresponding personal vehicles information under personal account from automobile intelligent upgrading software library and is
System firmware updating；
5) after downloading, the data integrity of intelligent terminal check system firmware updating weighs if data are imperfect
It is newly downloaded, until data are complete；
6) intelligent terminal sends to vehicle-mounted T-BOX and orders, and vehicle-mounted T-BOX, which is started the cycle over, judges whether the vehicle-state is in
The condition of system upgrade can be carried out by meeting vehicle electronic control unit；
7) in the case where meeting above system promotion condition, intelligent terminal begins through vehicle-mounted T-BOX to Vehicle Electronic Control list
Member carries out system upgrade；
8) after escalation process, intelligent terminal sends feedback information to cloud, and cloud is made to stop sending to personal account
The system upgrade information of the vehicle.
Vehicle-state, which is in, in the step 6) meets vehicle electronic control unit and can carry out the condition of system upgrade
Are as follows:
1. vehicle is in dead ship condition；
2. engine speed is zero, speed zero；
3. vehicle voltage is normal；
4. vehicle bus is normal, vehicle electronic control unit is connect normally with vehicle-mounted T-BOX.
Intelligent terminal in the step 7) begins through vehicle-mounted T-BOX to vehicle electronic control unit system
The step of system upgrading are as follows:
1. intelligent terminal reads the software and hardware version number of vehicle-mounted T-BOX and vehicle electronic control unit by APP；
2. intelligent terminal makes vehicle electronic control unit enter mode of extension by APP, vehicle electronic control unit is closed
After error code writing function, vehicle electronic control unit entrance writes with a brush dipped in Chinese ink mode and carries out secure access certification；
3. vehicle electronic control unit wipes internal storage after secure access certification passes through, vehicle-mounted T-BOX is from intelligent terminal
The internal storage of vehicle electronic control unit, and cyclic check system upgrade firmware is written in equipment down-loading system firmware updating
Data it is whether complete；
4. vehicle electronic control unit detects that the system upgrade firmware data of internal storage is complete, automotive electronics control is restarted
Unit processed.
Due to using above-mentioned technology, cloud sends vehicle upgrade information by personal account, and user is no matter when and where
Firmware updating can be independently downloaded by intelligent terminals such as mobile phones, in time, easily to the Vehicle Electronic Control list of vehicle
Member is upgraded, and is not needed user for vehicle and is reached the shop 4S, the time of user is greatly saved, moreover, because automotive electronics control
Unit upgrade job processed is voluntarily completed by user with mobile phone, and escalation process is simplified, and reduces the workload of the shop 4S staff.
Explanation of nouns:
1, intelligent terminal refers to those smart machines with multimedia function, these equipment support audio, video, data
Etc. function, comprising: videophone, conference terminal, PC, PDA of built-in multimedia function etc..
2, firmware (firmware) is generally stored in the electricallyerasable ROM (EEROM) EEPROM in equipment
In (Electrically Erasable Programmable ROM) or FLASH chip, it can generally be passed through by user specific
The program that refurbishing procedure is upgraded.In general, serve as that a digital product is most basic, the software of bottom work just may be used
With the basic input/output BIOS(Basic Input/output being referred to as on firmware, such as computer motherboard
System), in the past, more professional persons are its firmware in fact.
