Problems solved by technology

At the same time, in the semi-slip state, the engine speed is low, but the wheel speed is high, the vehicle can reverse the engine speed to increase, and the risk of stalling is still reduced. The published literature does not reflect this feature

Embodiment Construction

[0037] pass below Figure 1 ~ Figure 3 As well as listing some optional embodiments of the present invention, the technical solutions (including preferred technical solutions) of the present invention are further described in detail. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0038] Such as figure 1 As shown, the method for simulating shaking and flameout of the electric manual gear trainer car designed by the present invention is that the vehicle is driven by a motor, coupled with a manual gearbox through a clutch, and the output shaft of the manual gearbox is connected with a speed differential to transmit power to the left and right Half shafts for front wheel drive. The power source of the electr...

Abstract

The invention belongs to the technical field of electric vehicle control, and discloses a method for simulating vibration and flameout of an electric manual transmission coach car, comprising: after the vehicle is ready, reading engine speed, vehicle speed, gear information, clutch information and accelerator pedal information; Judging whether the vibration setting conditions are met according to the vehicle speed; when shaking, increase the output vibration torque with a certain frequency, amplitude and offset on the basis of the current request torque; judge whether to exit the vibration according to the engine speed; according to the duration of the vibration under different speeds and rotation speeds , the minimum speed threshold, the accelerator pedal information to calculate whether to turn off the engine; execute the turn off command, and turn off the "ready" indicator light. The invention can make the shaking and flameout characteristics closer to traditional fuel vehicles, save more energy when making shaking, and more meet the practical requirements of driving tests.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle control, and in particular relates to a method for simulating shaking and flameout of an electric manual transmission coach car. Background technique [0002] When the speed of the traditional internal combustion engine is low, it will automatically increase the speed sharply and then drop, so as to have the effect of acceleration frustrating, which will cause the frustrating and shaking of the vehicle in the front and rear directions. [0003] The electric manual transmission coach car has zero emissions, solves the problem of oil dependence, and the cost of electricity consumption is significantly lower than that of fuel oil. It has gradually become a hot spot for application in driving test places. However, the traditional internal combustion engine manual transmission training vehicle is still the mainstream. The operation skills learned by students on the manual transmission electric...
