Abstract
The invention solves the technical problem of providing a method for realizing smooth shifting of an electric automobile with a manual transmission case. The method solves the problem of shifting impact of the current electric automobile adopting the manual transmission case. When a driver releases an accelerator pedal, a detector, when detecting that an accelerator pedal signal is ineffective, performs 'idling' control over a drive motor with the signal, a brake torque is applied to allow the drive motor to simulate the process of rotation speed change generated when the accelerator pedal of an engine is completely released, and the driver realizes the stable shifting of the vehicle in the traditional shifting manner according to the current different gears and vehicle speeds in the process.
Description
Technical field
The present invention relates to Drive for EV and brake field, particularly the impact control method of drive system of electric automobile shift process.
Background technology
During the orthodox car gearshift, generally be at first power-transfer clutch to be separated, thereby make driving engine and car load realize breaking away from, the engine air throttle aperture reduces, driving engine is under the effect of self piston running resistance, rotating speed will reduce gradually, thereby make the change speed gear box combination gear can search out suitable shifting points preferably, realize the steady gearshift of automobile.Electronlmobil adopts the source of drive motor system as its propulsive effort more at present, and the mechanical specialities and the engine system of drive motor system are different fully.On the elec. vehicle of motor-driven and use Manual transmission, in shift process, driver habit is in adopting traditional gearshift mode and electric machine controller the behavior of motor not to be controlled, so because the suffered resistance of motor is little, motor is under the free state continuous running in higher rotation speed, and can not well mate with the moving velocity of automobile, so the problem of shift impact takes place in shift process easily.
Summary of the invention
Technical matters to be solved by this invention provides the method that a kind of electronlmobil that is suitable for Manual transmission is realized smooth-going gearshift, solves the problem of using the electronlmobil shift impact of Manual transmission at present.
The object of the present invention is achieved like this:
When the chaufeur release the gas pedal, detecting device detects the acceleration pedal invalidating signal, and with this signal drive motor is carried out " idling " control.It is the process of rotation speed change when by lock torque drive motor simulated engine Das Gaspedal being loosened fully that drive motor is carried out " idling " control, chaufeur is realized the steady gearshift of vehicle according to the current different gears and the speed of a motor vehicle according to traditional gearshift mode in the process of drive motor being carried out " idling " control.
Description of drawings
Accompanying drawing is a kind of motor control method diagram of circuit that imitates the engine gear process of the present invention.
The specific embodiment
Below will be described in detail the specific embodiment of the present invention with reference to the accompanying drawings.
The impact control method of drive system of electric automobile shift process of the present invention when acceleration pedal is released, detects the acceleration pedal invalidating signal, and with this signal drive motor is carried out " idling " control.It is the process of rotation speed change when by lock torque drive motor simulated engine Das Gaspedal being loosened fully that drive motor is carried out " idling " control, chaufeur is realized the steady gearshift of vehicle according to the current different gears and the speed of a motor vehicle according to traditional gearshift mode in the process of drive motor being carried out " idling " control.
Electric system in the shift process is carried out ACTIVE CONTROL, if system detects drive motor system rotating speed greater than " idling " rotating speed of setting, control system will force the drive motor system to be braked, make it rotating speed and be reduced to required rotating speed, realize smooth-going shift process, the electric energy that braking simultaneously produces will reclaim." idling " rotating speed of setting is determined by former car engine idling speed or by the experiment gained.
