The invention aims to provide an automobile mileage accumulation system and its control method. The automobile mileage accumulation system has accurate mileage accumulation and can avoid mileage accumulation data inaccuracy generated due to abnormal working of an odometer or replacement of an odometer. The system comprises an odometer having a mileage accumulation function, and an engine control module having a mileage accumulation function, wherein the odometer is connected with the engine control module, and the odometer and the engine control module adopt different signal sources in mileage accumulation. The inventive automobile mileage accumulation system has two mileage accumulation modes, can correct the accumulative value of mileage to make the value accurate, and effectively avoids mileage accumulation error caused by abnormal working of an odometer or replacement of an odometer.
Description
Technical field
The invention belongs to the automobile combination meter field of configuration, specially refer to a kind of speedometer for automobile accumulative total system and control method thereof.
Background technology
Development along with automotive engineering; People require increasingly highly to car load security and comfortableness, and simultaneously, main engine plants are for the product of better propaganda oneself and good after sale service; All product three guarantees mileage is defined; Such as 30,000/50,000 kilometers etc., and defined the scope and time of guarantee, and the mileage data of automobile kilometer are exactly the foundation whether client enjoys free quality guarantee.
Mileage is after automobile kilometer is received GES; The data that its internal calculation goes out are perhaps made mistakes (for example the inordinate wear of GES line causes signal not transmit, and sensor fault causes not having GES or sends wrong GES) if GES is unstable; And software occurs unusual; Can cause the automobile kilometer mileage not work or inaccurate, cause that the client complains, even cause the dispute between client and main engine plants.
In addition; The personal user constantly increases along with automobile, through regular meeting the certain user is taken place and appraises and decides free three guarantees purpose in addition in order to reach the automaker, can be through changing instrument; Perhaps in turn with two and above instrument; So that obtain more the maintenance, so not only damaged the interests of main engine plants, also be unfavorable for the safe in utilization of vehicle.And that the structure of traditional mileometer such as the patent No. are the utility model of CN200920205535 is disclosed, and speedometer comprises control chip, storer, decoding and display driver chip, charactron, also comprises the count signal pick-up unit.The count signal pick-up unit detects wheel turning collar number, and counting pulse signal is exported to control chip; Control chip calculates speed data according to counting pulse signal; And whenever just the accumulative total wheel number of turns in the storer is upgraded at a distance from one section timing; The accumulative total wheel number of turns after will upgrading again changes into mileage and speed data is transferred to decoding and display driver chip together; Decoding and display driver chip are deciphered mileage and speed data, and drive said charactron demonstration mileage and speed data.Above-mentioned speedometer in instrument, therefore can't be avoided the inaccurate problem of mileage data that is produced because of changing instrument privately with the mileage data storage.
Summary of the invention
The objective of the invention is to propose a kind of speedometer for automobile accumulative total system and control method thereof; The mileage of this kind speedometer for automobile accumulative total system is more accurate, the inaccurate problem of mileage data that can also avoid because of the mileometer operation irregularity simultaneously or change automobile kilometer and produced.
Speedometer for automobile of the present invention adds up system and comprises the mileometer with mileage function; Key is that this speedometer for automobile accumulative total system also comprises the engine control module with mileage function; Said mileometer links to each other with engine control module, and the signal source that said engine control module and mileometer are adopted when mileage is different.
Engine control module and mileometer adopt different signal sources to carry out mileage separately, through exchanges data, just can proofread and correct like this mileage value, thus the accuracy of assurance mileage.When the user changed mileometer privately, the mileage value deviation that engine control module and mileometer will occur was excessive, is easy to found by main engine plants or auto repair point.
Specifically, the mileage mode of speedometer for automobile of the present invention accumulative total system has following two kinds:
1, said engine control module links to each other with the wheel box module, and said engine control module receives first GES of wheel box module, and carries out mileage according to first GES; Said mileometer links to each other with vehicle speed sensor, and said mileometer receives second GES of vehicle speed sensor, and carries out mileage according to second GES.
2, speedometer for automobile according to claim 1 adds up system; It is characterized in that said engine control module links to each other with the wheel box module; Said engine control module receives first GES of wheel box module, and carries out mileage according to first GES; Said mileometer links to each other with the ABS module through car body controller, and said mileometer receives the 3rd GES of ABS module, and carries out mileage according to the 3rd GES.
Further, said engine control module links to each other with car body controller through the CAN network, and said car body controller links to each other with mileometer through the CAN network, to reduce wire harness quantity, makes things convenient for data forwarding, and guarantees that data transmission is accurate.
Further, said car body controller or mileometer are connected with the alarm device, with convenient the user are pointed out.
The control method of above-mentioned speedometer for automobile accumulative total system comprises the steps:
A: engine control module and mileometer carry out mileage separately;
B: engine control module sends to mileometer with the mileage value of statistics, and the user controls through the button of mileometer and shows mileage value that engine control module counted or the mileage value that mileometer counted.
The mileage value that mileage value that the user can see engine control module simultaneously and counted and mileometer are counted; So just can learn both gaps; And then learn that whether whether mileometer correct through the mileage statistical value of replacing or mileometer, avoided the inaccurate problem of mileage data that is produced because of changing automobile kilometer privately.
Further; The control method of above-mentioned speedometer for automobile accumulative total system also comprises step C: behind automotive ignition; Engine control module and mileometer carry out mileage relatively; When both differences of mileage value surpassed predetermined value, speedometer for automobile accumulative total system reported to the police through the alarm device.
Speedometer for automobile of the present invention adds up system and has two kinds of mileage modes, can proofread and correct the mileage value, makes its value more accurate, has effectively avoided the mileage mistake that causes because mileometer operation irregularity or user change its mileometer privately.
