The embodiment of the invention provides a segmented display method of endurance mileage, which comprises the following steps of:
101. and calculating a first endurance mileage and a second endurance mileage corresponding to the pure electric driving state according to the total electric quantity of the power battery, the current residual electric quantity, the preset charge state value and the real-time power consumption per kilometer.
Wherein, the driving state of the extended range electric automobile in the driving process is divided into two types: the range-extended electric vehicle comprises a pure electric driving state and a range-extended driving state, wherein when the range-extended electric vehicle drives in the pure electric driving state, a power battery in the range-extended electric vehicle provides power support for the range-extended electric vehicle; when the range-extended electric automobile runs in the range-extended running state, a range extender in the range-extended electric automobile provides power support for the range-extended electric automobile.
In practical applications, when the power battery is fully charged and the range extender is fully fueled, the range extender is generally driven by the electric vehicle with the following range extender: the power battery firstly uses part of electric quantity to provide power support for the extended range electric automobile; when the part of electric quantity is consumed, the range extending electric automobile starts the range extending device, and the range extending device provides power support for the range extending electric automobile by burning fuel; when the fuel in the range extender is consumed up, the power battery uses the rest electric quantity to provide power support for the range-extended electric automobile until the rest electric quantity is consumed up. Therefore, the amount of electricity in the power battery is divided into two parts: the first part of electric quantity and the second part of electric quantity enable the pure electric driving state to be divided into two types: the power battery is used for supplying power to the range-extended electric vehicle when the power battery uses the first part of electric quantity, and the range-extended electric vehicle runs in the first pure electric running state; when the power battery uses the second part of electric quantity to provide power support for the range-extended electric vehicle, the range-extended electric vehicle runs in the second pure electric mode state.
In the embodiment of the present invention, after obtaining the total electric quantity corresponding to the power battery, the current remaining electric quantity, the preset charge state value and the real-time power consumption per kilometer corresponding to the extended range electric vehicle (i.e. the electric quantity consumed per kilometer of the extended range electric vehicle), a first driving range and a second driving range of the extended range electric vehicle in the pure electric driving state can be calculated according to the total electric quantity corresponding to the power battery, the current remaining electric quantity, the preset charge state value and the real-time power consumption per kilometer corresponding to the extended range electric vehicle, i.e. the driving range of the extended range electric vehicle in the first pure electric driving state (first driving range) and the driving range of the extended range electric vehicle in the second pure electric driving state (second driving range), wherein the preset charge state value is the charge state value corresponding to the power battery when the extended range electric vehicle starts the extended range electric vehicle, the value range of the preset state of charge value is (0, 1), and the preset remaining electric quantity (i.e. the electric quantity of the remaining part of the power battery when the range extender is started by the range extender electric vehicle, i.e. the second part of the electric quantity of the power battery mentioned in the above section) can be calculated according to the preset state of charge value and the total electric quantity corresponding to the power battery.
102. And obtaining the residual fuel volume of the range extender, and calculating a third endurance mileage corresponding to the range-extending driving state according to the fuel conversion ratio, the residual fuel volume and the real-time power consumption per kilometer.

Specifically, in this step, the instantaneous oil consumption of the range extender within the preset time duration at each preset time interval may be obtained, and then the fuel conversion ratio may be calculated according to the second real-time output power corresponding to the range extender, the preset time duration, and the plurality of instantaneous oil consumptions corresponding to the range extender, but the method is not limited thereto.
103. And outputting and displaying the first endurance mileage, the second endurance mileage and the third endurance mileage.
In the embodiment of the invention, after the first endurance mileage and the second endurance mileage of the extended range electric vehicle in the pure electric driving state (i.e. the first endurance mileage of the extended range electric vehicle in the first pure electric driving state and the second endurance mileage of the extended range electric vehicle in the second pure electric driving state) and the third endurance mileage of the extended range electric vehicle in the extended range driving state are obtained through calculation, the first driving range of the extended range electric vehicle in the first pure electric driving state, the third driving range of the extended range electric vehicle in the extended range driving state, and the second driving range of the extended range electric vehicle in the second pure electric driving state can be sequentially output and displayed, so that a driver of the extended range electric vehicle can know which driving state the extended range electric vehicle is currently in, what the driving range of the extended range electric vehicle is in the driving state, and which driving state the extended range electric vehicle will drive next.
For example, when the power battery of the extended range electric vehicle is fully charged and the range extender is fully fueled, the mileage corresponding to the extended range electric vehicle is schematically displayed, as shown in fig. 2 a; when the extended range electric vehicle is in the first pure electric driving state, a driving range display diagram corresponding to the extended range electric vehicle is shown in fig. 2 b; when the range-extended electric vehicle is in the range-extended driving state, a driving range display diagram corresponding to the range-extended electric vehicle is shown in fig. 2 c; when the extended range electric vehicle is in the second pure electric driving state, a driving range display diagram corresponding to the extended range electric vehicle is shown in fig. 2 d.
Compared with the prior art that only displays the endurance mileage of the extended range electric vehicle in the pure electric driving state and the total endurance mileage in the pure electric driving state and the extended range driving state, the embodiment of the invention can calculate the first endurance mileage of the extended range electric vehicle in the first pure electric driving state and the second endurance mileage of the extended range electric vehicle in the second pure electric driving state according to the total electric quantity, the current remaining electric quantity, the preset charge state value and the real-time power consumption per kilometer corresponding to the extended range electric vehicle after acquiring the total electric quantity, the current remaining electric quantity, the preset charge state value and the real-time power consumption per kilometer corresponding to the extended range electric vehicle corresponding to the power battery, and after acquiring the residual fuel volume corresponding to the extended range device, and finally, outputting and displaying the first endurance mileage of the extended range electric automobile in the first pure electric driving state, the third endurance mileage of the extended range electric automobile in the extended range driving state and the second endurance mileage of the extended range electric automobile in the second pure electric driving state in sequence. Because the driving ranges of the extended range electric vehicle in the first pure electric driving state, the extended range driving state and the second pure electric driving state are respectively calculated and displayed, a driver of the extended range electric vehicle can accurately know which driving state the extended range electric vehicle is currently in, what the driving range of the extended range electric vehicle is in the driving state, and which driving state the extended range electric vehicle is to drive in next, so that the user experience of the driver can be improved.
