Detailed description of the invention
The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments:
Fig. 1 is the principle of the present invention figure.
Specific embodiment
A kind of vehicle power adjusting process, comprising:
One, ecu data are obtained from vehicle ecu and saves as ecu data file.
Two, the first address and data corresponding with first address are found from ecu data file, which is 8,
Totally 4 bytes.
Wherein, in the situation known to vehicle ecu software version, the first address is also it is known that and being stored in database
In, the address saved in the address of the data in ecu data file and database is matched, so that it may from ecu data text
The first address and data corresponding with first address are found in part.
The corresponding data in first address, which are used to calculate default, need to modify the position of MAP chart, avoid the kind of artificial judgment MAP chart
Class.
Three, high-low-position exchange is carried out to preceding 2 bytes of above-mentioned data and rear 2 bytes respectively, obtains address calculation
Parameter a and parameter b.
Four, pass through formula: (ECU software has determined the first address and the when generating MAP chart for the first address+(a+b) * 2+4
Two address relationship) the second address is obtained, the second address is that the data of smoke intensity limit coefficient MAP chart data store first address, is led to
The data memory length that a*b*2 calculates each data of smoke intensity limit coefficient MAP chart is crossed, smoke intensity limit is obtained according to data memory length
The address data memory of all data of coefficient MAP chart processed, and then each smoke intensity limit coefficient MAP is obtained according to each address data memory
Diagram data.
By taking P949V732 software as an example: if the first address is 06F74C, corresponding data are 0E000F00, then obtain
Address calculation parameter a and parameter b is respectively 000E and 000F.Then the second address is 0x06F74C+ (14+15) * 2=
The byte number (data memory length) in the region 0x06F78A, MAP is 14*15*2=420=0x1A4.
Wherein, smoke intensity limit coefficient MAP chart data are 8, totally 4 bytes, and preceding 2 bytes are x-axis coordinate data, rear 2
A byte is y-axis coordinate data, (exchanges mode and step after carrying out high-low-position exchange respectively to preceding 2 bytes and rear 2 bytes
Rapid three is identical) x-axis coordinate and y-axis coordinate can be obtained, x-axis coordinate is engine speed value, and y-axis coordinate is every circulation air matter
Amount is than smoke intensity limits value λ.
It is that can be adjusted and (be weighed between dynamic property and smoke intensity index) that wherein smoke intensity, which is limited in whole-car parameters,
, it is limited in a manner of influencing excess air coefficient, limit value is excessively tight, and low speed external characteristics torque may be influenced whether to body
The problem of dynamic property difference is reflected in present vehicle starting shift process.
Five, the x-axis coordinate data and y-axis coordinate data of each smoke intensity limit coefficient MAP chart data are located respectively
Reason, replaces the former data in above-mentioned ecu data file, generates new ecu data file after processing:
A, high-low-position exchange is carried out respectively to two bytes of two bytes of x-axis coordinate data and y-axis coordinate data
(exchange mode identical with step 3), and be converted to and select coefficient multiplied by user after 10 systems, 16 systems are converted to after rounding, use
Family selects coefficient for 0.75-1.
If x-axis coordinate data are 000C, then high-low-position exchange are carried out to 0C00, obtain 000C, be then converted to 000C
Coefficient is selected multiplied by user after 10 systems, then is rounded and is converted to 16 systems.
B, by two bytes point of the y-axis coordinate data after two bytes of the x-axis coordinate data after conversion and conversion
It carry out not high-low-position exchange.
C, x-axis coordinate data and y-axis coordinate data after exchanging high-low-position replace former x-axis coordinate data and y
Axial coordinate data.
Six, vehicle ecu is written into new ecu data file, adjustment is completed.
The present invention can efficiently carry out Self-regulation track, to realize enhancing engine cold-start speed, reduce fuel consumption
Target.
In the present embodiment, as shown in Figure 1, passing through VCI communication module 12 from vehicle diagnostics OBD by vehicle diagnostic equipment 11
Mouth 13 obtains the ecu data from vehicle ecu14, and ecu data file, vehicle diagnostics are saved as in vehicle diagnostic equipment 11
Equipment 11 and VCI communication module 12 are wired or be wirelessly connected, and VCI communication module 12 connect with vehicle diagnostics OBD mouth 13.
Wherein, vehicle diagnostic equipment provides graphic interface and selects above-mentioned user's selection coefficient for user.
Preferably, it is 0.8 or 0.9 that user, which selects coefficient, by experiment, user selects coefficient be 0.8 in the case where pass through
Cross adjustment, engine cold-start speed can improve 15-25%, and fuel consumption can reduce by 15%, user select coefficient for 0.9 feelings
Pass through adjustment under condition, engine cold-start speed can improve 3-10%, and fuel consumption can reduce by 5%.
But those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate this
Invention, and be not used as limitation of the invention, as long as in spirit of the invention, to embodiment described above
Variation, modification will all fall within the scope of claims of the present invention.
