Problems solved by technology
However, the current computer input signals needed to calculate real-time fuel consumption are likely to be invalid data. The existing technology cannot analyze the vehicle signals to determine whether they can be used, nor can they analyze whether they are consistent with the actual situation. It may cause unreal and overflow of data, and the input signal is constantly changing, causing the response speed to be too fast to make the numbers displayed on the instrument flutter and change, thus causing certain difficulties for the driver to observe real-time fuel consumption information

The invention provides a method for measuring automotive real-time fuel consumption, which comprises the following steps: acquiring fuel injection pulse signals, mileage pulse number and speed pulse signals, and calculating and obtaining consumed fuel, speed and travelled mileage according to the fuel injection pulse signals, the mileage pulse number and the speed pulse signals; judging whether the data is within an effective calculation range, and when the data is effective, performing first-order lag filter on the data value; and calculating and obtaining automotive real-time fuel consumption. According to the steps, the method can analyze and judge whether input signals are effective, and ensure the data reliability of calculated real-time fuel consumption, and the first-order lag filter for the input signals ensures that the real-time fuel consumption data displayed by a meter is not continuously updated, and is convenient for a driver to observe the real-time fuel consumption information.
Description
technical field [0001] The invention relates to a method for measuring fuel consumption of automobiles, and in particular to a method for measuring real-time fuel consumption of automobiles. Background technique [0002] In addition to displaying mileage, speed, speed, temperature and fuel level information, today's car instrumentation, the driver also wants to know information other than these basic information, so that the driver can better understand the driving situation of the car. Drivers hope that car dashboards can provide more car information, such as average fuel consumption, instantaneous fuel consumption, mileage, driving time, average speed, fuel remaining and outside temperature, etc. These driving information are more and more concerned by consumers , and are increasingly used in a variety of different models. We call this driving information the driving computer. They are obtained after comprehensive consideration of fuel consumption, remaining fuel volume,...
