Problems solved by technology

Through the digital instrument display mode, only the results can be read and the real-time data curve analysis function cannot be supported.
The traditional volumetric measurement method requires mileage accumulation, and the fuel consumption measurement is inaccurate when the driving mileage of the car is too short, and does not support fast and real-time gasoline consumption acquisition
Moreover, it is generally configured as a digital instrument display mode. There is no CAN communication interface dedicated to automotive calibration, and it cannot interface with automotive-specific calibration equipment, and cannot support online calibration work by automotive engineers.

Embodiment Construction

[0028] Such as figure 1 As shown, the online calibration equipment is used to read and write the engine controller 1 and the gearbox controller 2. The engine controller 1 is a calibrated engine controller that supports read and write operations, and the gearbox controller 2 supports read , write operation can be calibrated gearbox controller. Engine controller 1 and gearbox controller 2 are calibrated controllers that support read and write operations, that is, the online calibration device can read data from the controller, and can also write calibration data into the controller. Read the fuel consumption measuring instrument, and communicate with the data processing unit; the online calibration equipment is a kind of read and write operation for multiple target controllers: engine controller 1, gearbox controller 2, and can communicate with Data processing unit A device for data communication. It can pass data from the target controller to the laptop, and can also send ins...

Abstract

The invention discloses an on-line detection and calibration apparatus for oil consumption of an automobile. The on-line detection and calibration apparatus comprises an on-line calibration device, an automobile diagnosis interface, an oil consumption measuring instrument and a data processing unit. A gear value, engine rotating speed data, throttle data and speed data are read from en engine controller and a gearbox controller by means of an automobile diagnosis interface. Gasoline consumption information is read from the oil consumption measuring instrument. The above read information can be simultaneously transmitted to a laptop through the on-line calibration device, an automobile engineer calculates current gasoline consumption through a logic way according to all the read information in the laptop, and then a parameter correction instruction is emitted. In this way, the engineer obtains current oil consumption in real time from an automobile, updates corrected control parameters in a control system for an engine or a gearbox, also obtains running information of the automobile, and corrects the parameters more accurately. Furthermore, on-line repeatedly debugging can be conducted quickly, and the work efficiency can be effectively improved.

Description

technical field [0001] The invention relates to an on-line detection and calibration device for automobile fuel consumption. Background technique [0002] Low fuel consumption is an important performance for energy saving and emission reduction, environmental protection and fuel saving for drivers, and it is also the direction that automotive engineers continue to overcome. Automotive engineers need a set of efficient and practical vehicle fuel consumption testing and calibration equipment to optimize vehicle fuel consumption. Reducing vehicle fuel consumption through accurate data monitoring and online calibration can improve the efficiency of engineers in implementing fuel consumption optimization work, and can also improve the accuracy of calibration. [0003] At present, there is only a single fuel consumption measurement device, but no integrated fuel consumption detection and calibration equipment. Therefore, the current common fuel consumption detection and calibrat...
