Embodiment:
The present embodiment provides a kind of method that judgement oil float subcard is stagnant, different height of oil float in fuel tank is corresponding different
Resistance value, the height of oil float declines, the corresponding inversely proportional increase of resistance value with the reduction of oil mass；Automobile is in normal row
During sailing, according to current working oil consumption, oil mass is gradually reduced, and the height of oil float gradually declines, and resistance value is stepped up.If
Clamping stagnation exception occurs for oil float, even if amount of fuel reduces, the height of oil float does not decline, and resistance value does not have any variation, oil
Float is parked in current location and does not decline.At this point, instrument software needs to judge the exception of oil float.As shown in Fig. 2, automobile is travelling
In the process, according to current operating condition, oil consumption changes in a certain range.Using the sub- resistance value of every traveling Δ s km record oil float, combustion
Oily show value and current oil consumption record the sub- resistance value data of the oil float of running car S km altogether, use sliding window algorithm, analysis
The real-time dynamic changing curve of the sub- resistance value of oil float travels a distance, if the sub- resistance value of the oil float is not in that certain trend becomes
Change, i.e., oily float position does not change, then may determine that clamping stagnation occurs for oil float, need warning note driver current
Oil float, which has, occurs clamping stagnation exception, checks that the Fuel Oil Remaining in fuel tank needs to go to gas station to add immediately if oil mass is inadequate
Oil, and the fault condition for notifying the maintenance technician in the shop 4S service station to go to field assay oil float subcard stagnant, eliminate automobile because of oil
There is no gasoline in case, can not travel and give driver's bring security risk.
It can be, but not limited to, as shown in figure 3, the sub- resistance value data of the oil float are stored in external EEPROM or Flash,
In the process of moving, every traveling Δ s km saves one group of data to automobile, stores N group data, it is possible to reduce the total amount of data of storage.
Although reducing the total amount of data of storage, the total amount of data of storage is still very big, every group of 10 byte of data, data capacity
In several Kbytes to several Mbytes, it is excessive to be stored entirely in the memory space occupied in external equipment, needs to pass through data compression
Algorithm compresses data volume and reduces, and stores into external EEPROM or Flash.
When catching phenomenon has occurred in oil float in fuel tank, under the case where keeping the scene intact, do not need to tear fuel tank and oil open
Float connects instrument using external diagnostic instrumentation, reads the data being stored in external EEPROM or Flash, pass through
Data decompression algorithm restores the curve of the sub- resistance value dynamic change of oil float, stagnant at certain so as to analyze oil float subcard
A specific stopband position, find fuel gauge misregister basic reason be as oil float subcard it is stagnant caused by.
This programme uses the resistance value of real-time storage oil float, combines with the operating condition oil consumption of automobile, if automobile is travelling
The resistance value of certain distance, oil float does not change, then judges that clamping stagnation exception occurs in oil float, warning note driver excludes in advance
Because fuel tank does not have Fuel Remained, automobile can not travel bring security risk.
