Abstract
The invention discloses a method for indicating an automobile fuel meter and a device for indicating the automobile fuel meter, and refers to the field of indication of the automobile fuel meter. The method and the device for indicating the automobile fuel meter are used for solving the problems that the indication reaction speed of the existing automobile fuel meter is slow and a pointer is easy to shock. When an ignition switch is turned on, the fuel meter is worked under a refueling mode; after the pointer of the fuel meter reaches the indicated value, the fuel meter enters an ordinary mode; under the ordinary mode, the fuel meter enters the refueling mode if the car speed is zero always for continuously 12 seconds; under the refueling mode, the pointer of the fuel meter can determine the current position of the fuel pointer according to current actual sampling mean value; when the car speed is more than zero, the fuel meter instantly enters the ordinary mode. The fuel meter adopts a brand-new indicating method, and the indication responding speed is several seconds only; moreover, the indicating process is free from shock. The method and the device for indicating the automobile fuel meter are applicable to the technical field of reforming or manufacturing the automobile fuel meter.
Description
Technical field
The present invention relates to a kind of automobile fuel gauge indicating positions defining method and indicating device.Belong to automobile fuel gauge instruction field.
Background technology
Automobile fuel gauge realizes vehicle fuel amount device that is correct under different operating mode, that steadily indicate; existing vehicle is operated in general mode in the ignition trigger stage; the pointer change of this pattern instance fuel meter slowly; a few minutes are often needed to stablize; and sometimes also can along with violent shake, after the stable instruction of fuel gauge pointer, when from general mode in oiling mode handover procedure; the change of fuel gauge pointer is also slowly, often needs a few minutes to stablize.Fuel gauge, for showing amount of fuel, if can not reflect amount of fuel fast in time, will have a strong impact on the judgement of driver to vehicle condition.
Summary of the invention
The present invention is the problem that existing automobile fuel gauge Indicator Reaction speed is slow in order to solve, shake easily appears in pointer.A kind of indicating means and device of automobile fuel gauge are now provided.
An indicating means for automobile fuel gauge, it comprises the following steps:
When ignition switch is connected, fuel gauge is operated in oiling pattern, and fuel gauge pointer enters general mode after arriving indicated value,
In the normal mode, if the speed of a motor vehicle of continuous 12 seconds is always zero, then enter oiling pattern,
Under oiling pattern, fuel gauge pointer determines the current location of fuel oil pointer according to current actual samples mean value; When the speed of a motor vehicle is greater than zero, fuel gauge enters general mode at once.
An indicating device for automobile fuel gauge, it comprises with lower unit:
For when detecting that ignition switch is connected, make fuel gauge be operated in oiling pattern, and after detecting that fuel gauge pointer arrives indicated value, control the unit that fuel gauge enters general mode,
For in the normal mode, if when the speed of a motor vehicle of continuous 12 seconds is always zero, control the unit that fuel gauge enters oiling pattern,
For under oiling pattern, control fuel gauge pointer determines fuel oil pointer current location according to current actual samples mean value; And when detecting that the speed of a motor vehicle is greater than zero, control the unit that fuel gauge enters general mode at once.
Primary object of the present invention is the changing method of fuel gauge different working modes, be specially: when automobile starting, ignition switch is connected, fuel gauge is operated in oiling pattern, under oiling pattern, fuel gauge pointer determines the current location of fuel oil pointer according to current actual samples mean value, enables pointer reach steady state (SS) in the shortest time, thus substantially reducing the reaction time that fuel gauge enters general mode, a few second just can realize accurately instruction; When the speed of a motor vehicle is greater than zero, fuel gauge enters general mode at once, the time of 12 seconds is adopted to judge whether fuel gauge pointer stops having fluctuation, effectively can solve the jitter problem that oil meter pointer is existing in change procedure like this, when fuel gauge pointer does not fluctuate and automobile speed is zero, fuel gauge enters oiling pattern again, and under oiling pattern, pointer determines the current location of fuel oil pointer according to current actual samples mean value.
The present invention has abandoned the mode of operation of the usual display of existing fuel gauge completely, that is: the usual model selection mode of existing fuel gauge is not adopted, but look for another way, by switching the mode of operation of fuel gauge, realize in several cases, fuel gauge all can indicate amount of fuel fast, and effectively eliminates the strong feature of fuel gauge pointer jitter phenomenon performance in the course of the work, compared with existing fuel gauge, pointer response speed is from minute bringing up to several seconds.
