Description
Technical field
The invention belongs to technical field of automotive electronics, specially refer to a kind of vehicle fuel amount signal designation system and amount of fuel computing method.
Background technology
Along with progress and the development of society, China's automobile pollution constantly increases.Simultaneously, automotive electronic technology has also entered the epoch of a develop rapidly.For guaranteeing the normal safety traffic of automobile, people also more and more pay close attention to the various demonstration information of automobile.Wherein, the demonstration information of fuel gauge has been subject to paying attention to widely especially, and people need to understand current Fuel Oil Remaining from fuel gauge, thereby know course continuation mileage, guarantee normally to travel.Therefore, whether accurate the impact on the driver of fuel gauge indication be very large.
The principle of work of at present common amount of fuel computing method adopts shown in Figure 1.Fuel gauge directly gathers the resistance signal of fuel liquid level sensor, and then according to the corresponding relation of resistance and Fuel Oil Remaining, indicating member drives the fuel gauge pointer and is indicated to correspondence position.In the automobile normal running process, there are the various road surfaces of jolting such as upward slope, descending, affect the data acquisition of fuel liquid level sensor, in addition, in the process of driving, the interference that the high-power electric appliances such as operating air conditioner, windscreen wiper, loudspeaker can produce to fuel gauge electric signal unavoidably, above factor can cause the fuel gauge misregister, and may there be fuel gauge pointer phenomenon fluctuated, and real-time is bad, even exist fuel oil to be about to exhaust and serious problems that the driver does not know, bring great inconvenience for driver's driving.
Summary of the invention
The objective of the invention is to propose a kind of accurate, reliable vehicle fuel amount signal designation system and amount of fuel computing method.
Vehicle fuel amount signal designation of the present invention system comprises fuel liquid level sensor, control unit of engine and has memory module and the indicating member of computing module that described indicating member links to each other with fuel liquid level sensor, control unit of engine respectively.
For saving cost, described indicating member is automobile combination meter.
The amount of fuel computing method of above-mentioned vehicle fuel amount signal designation system are as follows: indicating member receives respectively the oil level signal of fuel liquid level sensor and the oil consumption signal of control unit of engine, then goes out current fr according to oil level signal and oil consumption calculated signals and indicates.
Specifically, above-mentioned amount of fuel computing method comprise the steps:
A: after each vehicle is flame-out, indicating member all stores oil mass value Voff in the value Vn of current fr and the detected fuel tank of fuel liquid level sensor this moment, and indicating member will be lighted a fire again, and the interior oil mass value Vig of the detected fuel tank of fuel liquid level sensor compares with Voff when powering on, if Voff-Vig＜predetermined value, illustrate that then parking period refuels, after starting indicating member with Vn as the amount of fuel initial value, if Voff-Vig 〉=predetermined value, illustrate that vehicle refuels, indicating member is with Vn+(Vig-Voff) as the amount of fuel initial value; Described predetermined value is greater than zero;
B: in startup and driving process, indicating member gathers the oil consumption signal by control unit of engine, and according to the amount of fuel that the oil consumption calculated signals goes out to consume, at last the amount of fuel initial value is deducted the amount of fuel that consumes, obtain current fr and indicate.
Further, described predetermined value is 4L, and predetermined value is too little to occur error easily, and predetermined value may well be missed very much the situation of a small amount of oiling.
Further, in the described A step, after 20 seconds, indicating member just utilizes fuel liquid level sensor to detect oil mass value Voff in the fuel tank behind the automobile flameout, calms down to guarantee the fuel oil in fuel tank this moment, and then guarantees that the Voff value is accurate.
Further, in the described B step, control unit of engine sends the oil consumption signal at each fixed cycle T1 to indicating member, indicating member refreshes once current fr of demonstration every predetermined space T2, described T2 is greater than T1, can reduce the computation burden of indicating member like this, and be convenient to show.
Vehicle fuel amount signal designation of the present invention system utilizes existing parts to convert, only under quiescent conditions, utilize fuel liquid level sensor to detect fuel liquid level in its amount of fuel computing method, can obtain comparatively accurately detected value, and only obtain actual fuel consumption by engine control system in the process of moving, so just shielded the measured deviation of fuel liquid level sensor in the situation of jolting, so that the current fr that calculates at last is accurate as far as possible.
