Embodiment Construction

[0058] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0059] A mileage simulation system for an extended-range electric vehicle, further comprising a driving condition module 1, a vehicle module 2, a wheel and drive shaft module 3, a reducer module 4, a gearbox module 5, a drive electric module 6, and a Power bus Module 7, range extender module 8, power battery module 9, controller module 10. Wherein the range extender module 8 comprises engine and generator sub-module, and this simulation system is as figure 1 shown.

[0060] Such as figure 1 As shown, the simulation system is mainly based on reverse calculation. Under the specific cycle condition 1, the driving resistance is obtained according to the vehicle module 2, and then the required torque and speed are calculated through the wheel and drive shaft module 3. The required torque C...

Abstract

The invention relates to an extended-range electric vehicle mileage simulation system and a simulation method thereof. The system comprises a driving condition module, a finished vehicle module, a wheel and drive shaft module, a speed reducer module, a gearbox module, a drive motor module, a Power bus module, a range extender module, a power battery module and a controller module, wherein the finished vehicle module is used for calculating running resistance, the speed reducer module and the gearbox module are used for calculating to obtain torque and speed requesting from the drive motor module, the Power bus module is used for reasonably allocating each demanded power, and the controller module is used for controlling systems of a finished vehicle according to different conditions. The method comprises the steps of modeling the finished vehicle and key components thereof, calculating the power demand under a cyclic condition, calculating the time duration according to the total energy of a power battery and a range extender system, and integrating the speed in the cyclic condition in the time duration to obtain the mileage.

Description

technical field [0001] The invention relates to a new energy vehicle, in particular to a simulation system and a simulation method for the driving range of an extended-range electric vehicle. Background technique [0002] Due to the global energy crisis and the decline of environmental quality, countries around the world have begun to develop new energy vehicles. Due to the limitation of power battery performance, the mileage of pure electric vehicles is relatively low, while extended-range electric vehicles can convert other energy sources into electric energy, making vehicles The mileage of driving does not have to be limited to the energy of the power battery, and the mileage of driving can be improved to a certain extent, which has been developed rapidly recently. [0003] The range-extended electric vehicle is based on a pure electric vehicle with a range extender system added. The range extender system is composed of an engine generator. When the power battery is low o...
