Problems solved by technology

[0004] As a driving school student, in the process of learning a manual transmission vehicle, it is inevitable that there will be a flameout phenomenon caused by various reasons. This flameout experience will promote the growth of the student. Therefore, using an electric vehicle as a driving school coach car first needs to simulate the traditional fuel oil. However, there is no mature solution for electric vehicles to simulate the flameout characteristics of traditional manual transmission fuel vehicles at home and abroad.

Embodiment Construction

[0053] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] The invention aims at the working characteristics of the electric vehicle drive motor in the prior art, especially the power output characteristics that are quite different from the internal combustion engine in the traditional vehicle, and if the electric vehicle is used in a driving school manual transmission coach vehicle, in addition to the need to increase the shifting mechanism, For the clutch mechanism, etc., it is also necessary to design a special control strategy to ensure that the driving experience is consistent with the traditional fuel vehicle, and to provide a vehicle control method, controller and electric vehicle.

[0055] like figure 1 As shown, the vehicle control method according to the embodiment of the present inven...

Abstract

The invention provides a vehicle control method, a controller and an electric vehicle, and relates to the control field of the electric vehicle. The vehicle control method includes: acquiring state information of vehicle flameout; determining a vehicle flameout mode according to the vehicle flameout state information; and controlling a motor speed according to the vehicle flameout mode. The embodiments of the present invention provide a vehicle control method that can truly simulate the driving experience of a traditional fuel vehicle during the flameout process, solves a major problem of electric vehicles as a coaching vehicle for driving schools, and does not involve the hardware of the original vehicle drive system. changes to ensure the simplicity and economy of operation.

Description

technical field [0001] The invention relates to the field of control for electric vehicles to simulate the flameout of fuel vehicles, in particular to a vehicle control method, a controller and an electric vehicle. Background technique [0002] With the rapid improvement of my country's economic level, automobiles have become common consumer goods and have entered the homes of ordinary people. Due to the large population in my country, there are also a large number of groups who need a driver's license for learning to drive. In this context, the domestic "learning to drive" The relevant industrial chain is booming. At this stage, most of the small coach vehicles used in driving schools in China are mainly fuel vehicles with manual transmission. Since the coach vehicles are mainly used for special skill training of students, they are in a low-speed driving state for a long time, such as starting, parking, idling, and reversing. Etc., compared with normal driving conditions, d...
