Abstract
A kind of method in the adjust automatically engine economical rotating speed area in instrument, comprises the steps：A) on vehicle after electricity, manufacturers of engines title, engine model and power number information are sent in CAN by Engine ECU by CI message informations, BCU receives the message information in CAN, and the now corresponding engine economical rotating speed area numerical value of manufacturers of engines title, engine model and power number information is inquired about in memory by message information, while the LED after controlling to be installed on the scale value of rotary speed area corresponding with engine economical rotating speed area in engine speed indicator is lighted.Human pilot can know the economic speed area for changing vehicle electromotor in instrument, to help which in driving to be maintained in economic speed area speed as far as possible, effectively reduce oil consumption.Can be with modularized production, it is adaptable to various, entrucking can matching use.
Description
Technical field
The present invention relates to a kind of method in the adjust automatically engine economical rotating speed area in instrument.
Background technology
The oil consumption for reducing vehicle has great significance to user.Generally user is that engine speed is maintained instrument as far as possible
The economic speed area that shows on table is realizing.And present medium and heavy commercial car is in order to improve the versatility of parts, its instrument
Table is generally all identical, and its engine economical rotating speed area for showing also all is fixed.But actually electromotor is different, its Jing
Often also difference is very big in Ji rotating speed area, it is therefore necessary to according to the economic speed area of engine information adjust automatically electromotor, with
User is helped to reduce oil consumption.
The content of the invention
The present invention is in order to overcome the shortcomings of above technology, there is provided one kind is looked into automatically according to engine model and power information
Its economic speed area is looked for and recognizes, so as to the method for the adjust automatically engine economical rotating speed area display content in instrument.
The present invention overcomes the technical scheme adopted by its technical problem to be：
A kind of method in the adjust automatically engine economical rotating speed area in instrument, comprises the steps
A), on vehicle after electricity, manufacturers of engines title, engine model and power number information are passed through by Engine ECU
CI message informations are sent in CAN, wherein by manufacturers of engines title, engine model and power number message information
SPN titles it is different, the manufacturers of engines title, engine model data type be character type, the power
Several data types is numeric type, and its unit is Kw；
B) corresponding with manufacturers of engines title, engine model and power number sending out is stored in the memorizer of BCU
Motivation economic speed area numerical value, BCU receive the message information in CAN, and inquire about this in memory by message information
When the corresponding engine economical rotating speed area numerical value of manufacturers of engines title, engine model and power number information；
C) BCU is installed in engine speed indicator and electromotor according to the engine economical rotating speed area numerical control for inquiring
LED after the scale value of the corresponding rotary speed area in economic speed area is lighted.
In order to meet rational display economic speed area when using new work engine, when step b）Middle BCU is without from depositing
When the engine economical rotating speed area numerical value corresponding with the message information that ECU sends is inquired in reservoir, then not execution step c),
Now BCU is installed in engine speed indicator after the scale value of rotary speed area corresponding with default value according to default value control
LED is lighted, and the default value is 1000-1500rpm.
Show in order to trivial with red rotating speed clearly, the LED in above-mentioned steps c) adopts green LED.
The invention has the beneficial effects as follows：Human pilot can know the economic speed of the vehicle electromotor in instrument
Area, to help which in driving to be maintained in economic speed area speed as far as possible, effectively reduces oil consumption.Simultaneously because BCU storages
All manufacturers of engines titles, engine model and power number that automobile production producer uses can be stored in device corresponding
Economic speed area numerical value, therefore can be with modularized production, it is adaptable to various, entrucking can matching uses.
Description of the drawings
Fig. 1 is method of the present invention flow chart.
Specific embodiment
1 the present invention will be further described below in conjunction with the accompanying drawings.
A kind of method in the adjust automatically engine economical rotating speed area in instrument, comprises the steps
A), on vehicle after electricity, manufacturers of engines title, engine model and power number information are passed through by Engine ECU
CI message informations are sent in CAN, wherein by manufacturers of engines title, engine model and power number message information
SPN titles it is different, manufacturers of engines title, engine model data type be character type, the data of power number
Type is numeric type, and its unit is Kw.B) in the memorizer of BCU storage with manufacturers of engines title, engine model and
The corresponding engine economical rotating speed area numerical value of power number, BCU receive the message information in CAN, and pass through message information
Inquire about the corresponding electromotor economy of now manufacturers of engines title, engine model and power number information in memory to turn
Fast area's numerical value.C) BCU is installed in engine speed indicator and is started according to the engine economical rotating speed area numerical control for inquiring
LED after the scale value of the corresponding rotary speed area in machine economic speed area is lighted.Now human pilot can be obtained in instrument
Know the economic speed area of the vehicle electromotor, to help which in driving to be maintained in economic speed area, effectively speed as far as possible
Reduce oil consumption.Simultaneously because all manufacturers of engines titles that automobile production producer uses being stored in BCU memorizeies, being sent out
Motivation model and the corresponding economic speed area numerical value of power number, therefore can be with modularized production, it is adaptable to various, entrucking
Can matching use.
When step b）Middle BCU is no to inquire the electromotor Jing corresponding with the message information that ECU sends from memorizer
During Ji rotating speed area's numerical value, then not execution step c).Illustrating now may be using new spec, the electromotor of new producer, and BCU is deposited
Data in reservoir also do not upgrade in time.Now BCU is installed in engine speed indicator and default value according to default value control
LED after the scale value of corresponding rotary speed area is lighted, and default value is 1000-1500rpm.Due to the Jing of most of diesel engine
Ji rotating speed area is all in the range of speeds of 1000-1500rpm, therefore arranges default value by rational, makes to send out same in instrument
The economic speed area of transmitter rotating speed can be shown, a help user reduces oil consumption in vehicle travel process.
LED in step c) adopts green LED.Show that engine economical rotating speed area can be with sending out using the LED of green
The red rotating speed of motivation is trivial clearly demarcated aobvious, is easy to driver to observe.
