Method, device and vehicle for detecting remaining fuel volume in fuel tank

Abstract

The invention discloses an oil tank remaining oil volume detection method, device and vehicle. The method comprises the following steps of determining whether a vehicle is at an oiling state, acquiring a gradient signal of a road surface where a vehicle lies and a detection value of an oil level sensor if the vehicle is at the oiling state, and checking a preset oil volume matrix according to the gradient signal and the detection value of the oil level sensor, and updating and displaying a fuel oil display value of an instrument. According to the oil tank remaining oil volume detection method of the embodiment, a problem of inaccurate oil level information collected by the oil level sensor when the vehicle is on a non-horizontal ground can be solved, so accuracy of the fuel oil display value of the instrument can be greatly improved and use experience can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a detection method, device and vehicle for remaining fuel in a fuel tank. Background technique [0002] The development of the automobile industry in our country is becoming more and more mature. Almost every family now has a passenger car. The service system across the country has also been perfected. Cars can travel anywhere in the world. [0003] In the current mature automobile market, all companies will speed up their research and development progress, save costs, and develop high-tech. The methods adopted by many automobile manufacturers are the fuel resistance signal acquisition method. Fuel resistance signal acquisition method, that is, the fuel level sensor will transmit a resistance signal externally, and a pull-up resistor above the circuit is used to divide the voltage. Through the change of the resistance value, the AD acquisition port on the instrument side can co...

Problems solved by technology

[0004] However, with the development of automobiles, the shape and placement rules of fuel tanks are increasingly deviated from traditional methods. In the past, they were all three-dimensional fuel tanks, usually placed at the bottom or tail, but they were all placed vertically or horizontally in a regular manner. Sometimes, in order to speed up the research and development progress of models and save costs, when the mold opening of the car shape and the chassis structure remain unchanged, some irregular fuel tanks, when placed arbitrarily, will lead to fuel failure when the fuel display strategy remains unchanged. Inaccurate display

For example, when the shape of the fuel tank is irregular, the resistance signal transmitted by the fuel level sensor according to the actual fuel volume will produce errors, and this error will become larger and larger during the driving process of the vehicle, resulting in cumulative errors. And when the vehicle parks on a slope, refuels on a slope, replaces an instrument on a slope, accelerates rapidly, decelerates sharply, brakes sharply, and drives on a curve, the fuel resistance value of the vehicle collected by the fuel level sensor will Inaccurate, resulting in a discrepancy between the oil quantity displayed on the gauge and the actual value, which in turn leads to poor user experience
