Description
Technical field
The present invention relates to technical field of automotive electronics, the running car total kilometrage being specifically related in instrument keeps system and side
Method.
Background technology
Instrument records the total mileage number of automobile, and usual running car is a bit of, and such as 1 kilometer, instrument amounts to mileage number
Just update once, keep and running car distance synchronous.It is an important parameter of the newness degree of display automobile.But
Instrument break down or need to optimize thus when carrying out software upgrading or change, if imprudence removes instrument record
Total kilometrage number, or after more renewing instrument, total kilometrage number is 0, and the just display of the real distance travelled of automobile the most out, affects automobile
Maintenance and the fairness of transaction.
Summary of the invention
For solving above-mentioned technical problem, the invention provides one will not cause because changing the factor such as instrument or software upgrading
Running car total kilometrage in the instrument that running car total kilometrage is lost keeps system and method.
Running car total kilometrage in instrument a kind of for the present invention keeps system, and its technical scheme is, including
Mileage calculation device: for calculating mileage amount of change Δ l in real time according to automobile's instant velocity, and mileage amount of change Δ l is led to
Cross CAN network and be sent to instrument；
Instrument memorizer: for according to mileage amount of change Δ l, calculates traveling total kilometrage L-value in real time, and will travel total in
Journey L-value is written in the total kilometrage number storage address of instrument, the traveling total kilometrage L-value calculated is sent to automobile body simultaneously
Controller；
Car body controller: be provided with the memory block travelling total kilometrage for storing vehicle in the depositor of described car body controller
Between, described car body controller backs up for the traveling total kilometrage value that instrument memorizer calculates gained.
Further, during described mileage calculation device is anti-sideslip system, anti-lock braking system, automatic parameter case controller arbitrarily
A kind of.
Running car total kilometrage keeping method in instrument a kind of for the present invention, its technical scheme is, instrument memorizer
Constantly traveling total kilometrage is calculated and stores, every one section of operating range, in the instrument memorizer traveling to storing is total
Number of passes is according to being updated, and the traveling total kilometrage value after updating is sent to car body controller and backs up.
Further, every certain mileage number amount of change, instrument memorizer and car body controller once travel always
The check of mileage value, if the total kilometrage value that travels of instrument memorizer storage is more than the traveling total kilometrage of the interior storage of car body controller
Value, then the traveling total kilometrage value of storage is sent to car body controller by instrument memorizer, if the traveling of instrument memorizer storage is total
Mileage value is less than the traveling total kilometrage value of storage in car body controller, then the traveling total kilometrage value of storage is sent by car body controller
To instrument memorizer.
Further, the traveling total kilometrage calculating process of described instrument memorizer is: in calculating in real time according to automobile's instant velocity
Journey amount of change Δ l, and mileage amount of change Δ l is counted traveling total kilometrage value, to obtain up-to-date traveling total kilometrage value.
Further, described mileage amount of change Δ l=V* Δ t, wherein V is automobile's instant velocity, and Δ t is for calculating time interval.
Further, the mileage amount of change Δ l value every time calculated is added up, when the mileage amount of change repeatedly calculated is tired out
When product value reaches calibration value, mileage amount of change aggregate-value Δ L is sent to instrument memorizer, in instrument memorizer obtains always travelling
Journey L=L0+ΔL。
Further, when vehicle powers on, described instrument memorizer and car body controller once travel total kilometrage L-value
Check, and higher value is stored.
Beneficial effects of the present invention: the traveling total kilometrage value after updating due to instrument is sent to car body controller and carries out standby
Part, therefore in instrument after software upgrading after sale or changing, by with car body controller carry out proofreading and write traveling total in
Journey value, can reach the purpose keeping travelling total kilometrage, and the prompting preventing vehicle maintenance next time is chaotic, safeguards that user's is normal
Maintenance；Prevent from that instrument total kilometrage number carries out malice to write simultaneously, gross vehicle mileage number is faked, these public affairs to Second-hand Vehicle Transaction
Positivity has the most necessary meaning.
Accompanying drawing explanation
Fig. 1 is module connection diagram of the present invention；
Fig. 2 is control flow chart of the present invention；
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail:
As it is shown in figure 1, the present invention includes mileage calculation device, instrument memorizer and car body controller.Mileage calculation device is anti-
In sideslip system ESP, anti-lock braking system ABS, automatic parameter case controller TCU any one, in the depositor of car body controller
It is provided with the storage interval travelling total kilometrage for storing vehicle.
As in figure 2 it is shown, during normal vehicle operation, mileage calculation device Δ t at set intervals calculates a mileage amount of change,
Mileage amount of change Δ l=V* Δ t, wherein V is automobile's instant velocity, and in the present embodiment, Δ t takes 10ms.To the mileage change calculated every time
Amount Δ l value adds up, when the mileage amount of change accumulated value repeatedly calculated reaches 1km (occurrence can freely be demarcated), by inner
Journey amount of change aggregate-value Δ L is sent to instrument memorizer, and instrument memorizer obtains travelling total kilometrage L=L0+ Δ L, wherein L0For more
Total kilometrage value before new, when vehicle release, L0It is 0.
Every certain mileage number amount of change Δ L1(such as 100km, can demarcate), car body controller BCM and instrument memorizer
Check once mutually.If the traveling total kilometrage L-value of instrument memorizer storage is more than car body controller internal memory Stored Value, then instrument storage
The traveling total kilometrage L-value of storage is sent to car body controller by device, if the traveling total kilometrage L-value of instrument memorizer storage is less than car
Body controller internal memory Stored Value, then the traveling total kilometrage L-value of storage is sent to instrument memorizer by car body controller.
If needing after sale to refresh instrument software, the address of instrument storage total kilometrage number is not included in refresh ranges.Simultaneously
Have recorded the true total kilometrage number that travels of vehicle in BCM, with checking mutually of BCM, instrument ensures that instrument remains real car
Travel total kilometrage.If being changed instrument after sale, after instrument is changed, it is 0 that registration of vehicle travels total kilometrage number, works as vehicle
Travel Δ L1Distance after, the result checked mutually of instrument and BCM is total more than instrument record of the total kilometrage number of BCM record
Mileage number, so the total kilometrage number that BCM is recorded by instrument is written in the storage address of self, thus ensures not affect under vehicle
Maintenance mileage once, also avoids producing practising fraud of artificial shortening VMT Vehicle-Miles of Travel, it is ensured that vehicle transaction
Fairness.
The above, the only detailed description of the invention of the present invention, it is noted that any those of ordinary skill in the art exist
In the technical scope that disclosed herein, the change that can readily occur in or replacement, all should contain protection scope of the present invention it
In.
