Problems solved by technology

Since there are two energy sources in the extended-range electric vehicle, and these two energy sources can determine which energy source is used to drive the vehicle through the driver's input, so the treatment of the cruising range cannot be completely followed by the traditional car or the pure electric vehicle. How to deal with mileage

Abstract

The invention relates to a continuous driving mileage display system of a range-extending type electric car. The continuous driving mileage display system comprises a collecting unit, a processing module, a conversion module and a display unit. The collecting unit is used for collecting measured quantity of a fuel tank and quantity of battery power E; the processing module is used for calculating energy fuel E corresponding to residual fuel quantity according to the residual fuel quantity and power average fuel consumption rate; the conversion module comprises a first conversion unit and a second conversion unit, the first conversion unit receives the power E and the fuel E and converts the power E and the fuel E into the SOC value to output to the second conversion unit, and the second conversion unit converts the SOC value into continuous driving mileage SX; the display unit receives and displays the continuous driving mileage SX outputted by the second conversion unit. The energy that can be supplied by the fuel is calculated, the energy supplied by the fuel and electric energy is converted into the battery power quantity, and the mileage corresponding to the battery power quantity is known, so that the continuous driving mileage can be calculated and displayed on the display unit, and refueling and charging in time are facilitated for drivers.

Description

technical field [0001] The invention relates to the technical field of control of an extended-range electric vehicle, in particular to a cruising range display system of an extended-range electric vehicle. Background technique [0002] With the progress of society, people's awareness of environmental protection has increased, and they have begun to advocate "low-carbon, environmentally friendly, and green" travel methods, making the research on high-efficiency, environmentally friendly, and energy-saving electric vehicles aroused great attention from automobile manufacturers around the world. The range-extended electric vehicle is a pure electric vehicle with an energy supplement unit designed to solve the short mileage of pure electric vehicles. When the battery power of the extended-range electric vehicle is sufficient, the motor is driven by the power battery to provide the driving power demand of the whole vehicle. At this time The engine does not participate in the work...
