Embodiment Construction
[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] see figure 1 , an embodiment of the present invention provides a method for measuring vehicle fuel consumption, the method comprising:
[0040] Step 1: Obtain oil volume data records and sort the acquired oil volume data records by time;
[0041] Step 2: Determine whether the first fuel volume data record of the day was obtained when the vehicle was turned off, if yes, go to step 3, otherwise, go to step 4;
[0042] Step 3: Calculate the first steady point of oil volume P1 according to the remaining oil volume values in the first and subsequent preset oil volume data records;
[0043] Step 4: Search down from the first fuel volume data record of the day to find out the first fuel volume data record when the vehicle is off, a...

The invention relates to the field of vehicle monitoring, in particular to a vehicle oil consumption measuring method. The method comprises the steps of obtaining oil mass data records and sorting the records according to time; judging whether the first oil mass data record on the day is obtained under the vehicle closed state or not, if yes, calculating a first oil mass stationary point P1 according to the first oil mass data record and remaining oil mass values in the next following preset oil mass data record, if not, calculating a second oil mass stationary point P1' with the same method, and compensating for the P1'; judging whether the final oil mass data record on the day is obtained when a vehicle is closed or not, if yes, calculating a third oil mass stationary point P2 according to the final oil mass data record and remaining oil mass values in the next forward preset oil mass data record, if not, calculating a fourth oil mass stationary point P2' with the same method, and compensating for the P2'; calculating the oil consumption difference value; determining that the oil consumption on the day of the vehicle is the sum of the difference values of the oil consumption on the day and the oil consumption. According to the method, the measuring efficiency is high, time and labor are greatly saved, and the higher measuring precision is achieved.
Description
technical field [0001] The invention relates to the field of vehicle monitoring, in particular to a method for measuring vehicle fuel consumption. Background technique [0002] The fuel consumption of a car traveling 100km is commonly known as fuel consumption. Automobile fuel consumption has become the most important indicator that automobile manufacturers and automobile users pay attention to. Because constant speed driving is a basic working condition for automobiles running on the road, this kind of fuel consumption is easy to measure, so constant speed fuel consumption is widely used. However, because the car often has various working conditions such as acceleration, deceleration, braking and engine idling during actual driving, the fuel consumption at constant speeds is often low, which is quite different from the actual fuel consumption. [0003] In order to carry out refined management of vehicle fuel consumption, the existing technology uses GPS monitoring technol...
