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 object, technical solution 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 present invention is aimed at the operating characteristics of the drive motor of the electric vehicle in the prior art, especially the power output characteristic is quite different from the internal combustion engine in the traditional vehicle, and if the electric vehicle is used for the manual gear trainer car in the driving school, in addition to the need to increase the shifting mechanism, Clutch mechanisms, etc., also need to design a special control strategy to ensure that the driving experience is consistent with traditional fuel vehicles, and provide a vehicle control method, controller and electric vehicles.

[0055] Such as figure 1 As shown, the control method of the vehicle in the embodiment of the present invention includes:...

Abstract

The invention provides a vehicle control method, a controller and an electric vehicle, and relates to the field of electric vehicle control. The vehicle control method comprises the steps of acquiringflameout state information of the vehicle; determining a flameout mode of the vehicle according to the flameout state information of the vehicle; and controlling the rotating speed of a motor according to the flameout mode of the vehicle. According to the embodiment of the invention, the vehicle control method can truly simulate the driving experience of a traditional fuel vehicle in the flameoutprocess, solves a big problem that an electric vehicle serves as a learner-driven vehicle for a driving school, does not involve the change of hardware of an original vehicle driving system, and guarantees the simplicity and economical efficiency of implementation operation.

Description

technical field [0001] The invention relates to the field of control of an electric vehicle simulating flameout of a fuel vehicle, 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, cars have become ordinary consumer goods and have entered the homes of ordinary people. Due to the large population of our country, there are also very large groups of people who need to learn to drive and test their driver's license. Under this background, the domestic "learning to drive" Related industrial chains are booming. At this stage, most of the small coach cars used in driving schools in China are mainly manual transmission fuel vehicles. Because the driving school coach cars are mainly used for special skill training for 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 c...
