Calculation method of oil remaining amount endurance mileage reminding function

Abstract

The invention provides a calculation method for an oil remaining amount endurance mileage reminding function, and belongs to the field of commercial vehicle electronic control. The method comprises the steps that the current total remaining oil amount of an oil tank is multiplied by the average oil consumption of the current driving cycle, and the endurance mileage corresponding to the remaining oil amount of the current driving cycle is obtained; the vehicle is powered on, the total driving mileage and the total oil consumption of the last driving cycle are called, the driving mileage and the oil consumption of the current driving cycle are calculated, logic judgment is conducted on the driving mileage state of the current driving cycle, and logic judgment is conducted on the oil consumption state of the current driving cycle; the average oil consumption of the current driving cycle is calculated; a final average fuel consumption value of the current driving cycle is obtained by taking a key power-on state as a judgment condition; and the calculated current driving cycle remaining oil quantity corresponds to the endurance mileage value, and the endurance mileage value is sent to an instrument through a CAN line to be displayed. A driver can more accurately and visually know the oil remaining amount of the fuel tank, the driver is reminded of refueling in time, the blank of the function of a commercial vehicle is filled, and the method is suitable for large-scale application.

Description

technical field [0001] The invention relates to the field of electronic control of commercial vehicles, in particular to a calculation method for a reminder function of fuel remaining cruising range. Background technique [0002] With the development of social economy, the important role of commercial vehicles is self-evident. Commercial vehicles have the characteristics of large load capacity and long mileage. Reminding the driver to refuel in a timely and intuitive way can not only ensure the progress of logistics, but also the basis of driving reliability. [0003] At present, the function of calculating and displaying the mileage corresponding to the remaining amount of fuel in the fuel tank generally exists in passenger cars, and commercial vehicles basically do not have this function. Not guaranteed. Contents of the invention [0004] In order to enable the driver of a commercial vehicle to understand the fuel information of the vehicle and ensure the reliability o...
