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] like 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 electric ...

Abstract

The invention belongs to the technical field of electric vehicle control, and discloses a method for simulating jitter and flameout of an electric manual gear instructional vehicle, which comprises the following steps: after the vehicle is ready, reading engine speed, vehicle speed, gear information, clutch information and accelerator pedal information; judging whether jitter setting conditions are met according to the rotating speed and the vehicle speed; during jittering, adding and outputting jittering torque with certain frequency, amplitude and offset on the basis of the current request torque; judging whether to quit jitter according to the engine speed; calculating whether flameout is carried out according to the shaking duration, the minimum rotating speed threshold value and accelerator pedal information under different vehicle speeds and rotating speeds; executing the flameout instruction, and extinguishing the 'read 'indicator lamp. According to the method, the shaking and flameout characteristics are closer to those of a traditional fuel vehicle, more energy is saved during shaking, and the driving test practice requirements are better met.

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...
