Abstract

The invention relates to the field of vehicles, and discloses a driving method of an extended-range automobile. By the adoption of the driving method of the extended-range automobile, when the automobile runs in low-noise and low-emission places such as schools, hospitals and residential areas with certain requirements for noise, a first range extender is used for supplying power to the driving motor, a power battery works in a matched mode, and low-noise and low-emission running can be achieved; in suburb areas and other areas with low requirements for noise and emission, a second range extender is used for supplying power to the driving motor, and the power battery works in a matched mode; and under the constraint of the capacity and the volume of the power battery, the driving time of the traditional extended-range automobile is short, and the first range extender or the second range extender is selected to be matched with the power battery to work according to the road condition, so that the charging and discharging times of the power battery can be reduced, the charging and discharging loss of the power battery is reduced, and the driving time of the extended-range automobileis prolonged.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a driving method for an extended-range vehicle. Background technique [0002] With the increasingly severe energy crisis and environmental pollution, hybrid electric vehicles have become a trend in the field of automotive technology development. Among them, the extended-range vehicle is a simple and easy way to transform the traditional internal combustion engine vehicle. The range-extended vehicle improves the power system on the basis of the internal combustion engine vehicle, adds a range extender, a power battery and a drive motor, and drives the vehicle through the motor to improve the economy and power of the vehicle. In models with this architecture, when the car is running and the power battery is sufficient, the power battery drives the motor in pure electric mode to meet low emissions; when the power battery is insufficient, the range extender does not need to stop. Instead of...
