Control method and system of electric vehicle simulating fuel vehicle engine flameout condition, and electric vehicle

Abstract

The invention relates to a control method of an electric vehicle simulating engine flameout condition of a fuel vehicle, a system and the electric vehicle, wherein the control method comprises a stepof simulating a working state of a manual gear shift, an engine speed simulation step, a data acquisition step, a shift judgment step, a Vehicle speed judging step, A timing step and a flameout signaltransmission step, By obtaining the current speed of the electric vehicle, engine simulation rotational speed and current gear value, judging and comparing with corresponding threshold value, entering timing according to judging and comparing result and sending out flameout signal according to judging according to timing, the series of specific steps are finished, , thus finally realizing the fuel vehicle engine flameout condition simulation of electric vehicle , The electric vehicle can truly and reliably simulate all kinds of situations in which the traditional fuel vehicle stops because ofthe improper operation of the driver in the driving school study or test process, so that the operation method and operation result of the electric vehicle and the traditional fuel vehicle are consistent, and the electric vehicle can be applied in the driving school.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method and system for an electric vehicle to simulate a flameout working condition of an engine of a fuel vehicle, and the electric vehicle. Background technique [0002] With the development of the automobile industry, green, clean and environment-friendly electric vehicles are more and more supported and loved by the country and the people, and have gradually been widely used, especially in places with high population density, such as driving schools and other places. Electric vehicles are undoubtedly very suitable, not only to avoid the low fuel utilization rate of the engine at low speed, but also to have no exhaust emissions and no pollution to the environment. In order to promote the development of new energy and protect the environment, many driving schools have begun to use electric vehicles as coaches and test vehicles to alleviate the dependence on t...
