Fig. 3 is the flow chart for the control method that hand gear is carried out using the embodiment of the present invention.As shown in figure 3, the control
Method comprises the following steps：
Judge whether electric clutch pedal 41 is operated.
If electric clutch pedal 41 is operated, to whole after the gearshift demand of the acquisition driver of electric clutch pedal 41
Vehicle controller 100 sends shifting commands signal.
Entire car controller 100 is turned off according to the shifting commands signal control electric control clutch 21 received.
After entire car controller 100 receives shifting commands signal, electric control clutch 21 is controlled by clutch actuating mechanism 22
Separated, so as to complete the disconnection to driving motor 11 and manual transmission 31, reach the demand of vehicle shift.
After 31 manual shift of manual transmission to demand gear, entire car controller 100 is according to the operation shape of current vehicle
Condition control driving motor 11 reaches demand torque and demand rotating speed.
According to needs are driven, manually gearbox 31 adjusts gear to demand gear, so as to meet vehicle traveling
Rotating speed and torque demand.The rotating speed and torque demand that entire car controller 100 is travelled according to current vehicle adjust driving motor 11 and reach
To corresponding demand moment of torsion and demand rotating speed, the size and frequency of the three-phase current exported by regulation motor controller 12, with
For controlling the output torque and rotating speed of driving motor 11.
After the release of electric clutch pedal 41, entire car controller 100 controls electric control clutch 21 to be attracted, and completes hand
Dynamic speed change.
When manual transmission 31 reaches predetermined gear, and driving motor 11 reaches corresponding output torque and rotating speed, pine
The switch of electric clutch pedal 41 is driven, entire car controller 100 controls electric control clutch 21 to be attracted, and drives motor 11 at this time
It is connected by electric control clutch 21 with manual transmission 31, driving motor 11 can export power to manual transmission 31, complete
Into hand gear.
Wherein, the definite method that the control of entire car controller 100 drives motor 11 to reach demand rotating speed comprises the following steps：

Hand engaging gear is completed, entire car controller 100 controls to adjust the rotating speed of driving motor 11 by electric machine controller 12 so that driving electricity
The rotating speed of machine 11 is equal to the input shaft rotating speed of current manual gearbox 31.
If the numerical value of rotating ratio judges manual transmission 31 not equal to any one in the gear level of manual transmission 31
Hand engaging gear is not completed, the driving 11 rotational speed regulation moment of motor is improper, also needs to continue to wait.
Further, smooth gear shifting and to subtract when ensureing that clutch actuating mechanism 22 controls electric control clutch 21 to be attracted
The abrasion of small electric control clutch 21, the control driving motor 11 of entire car controller 100 reach in demand Rotation Process, drive motor 11
The absolute value of difference of input shaft rotating speed of actual speed and manual transmission 31 should keep in a certain range.
Further, when driver's brake pedal 43, entire car controller 100 can control power set to enter system
Energy take-back model.In the process, to recycle braking energy and lifting brake force to the full extent, driver not carry out
Gear shift operation.
Further, whether entire car controller 100 can judge electric automobile according to the Slope Transducer signal received
Climbing, and adjust the output torque of driving motor 11.Entire car controller 100 can receive the signal that Slope Transducer is sent, and
Judge whether vehicle is in climbing state journey, and the gradient of climbing according to the signal.For the gradient of different range, set and drive
The different moment of torsion of dynamic motor 11 corresponds to the depth and motor speed of accelerator pedal 42, controls and drives for entire car controller 100
The torque output of motor 11.
Meanwhile when parking brake pull-up, parking brake signal is input to entire car controller 100, entire car controller 100 is stepped on reference to braking
Plate 43, accelerator pedal 42, output shaft of gear-box tach signal, motor speed etc., judge whether vehicle enters parked state.
Control system described in the present embodiment also has the function of anti-slip by slope.When vehicle half way up the mountain is started to walk upwards, driver draws
Parking brake, steps on brake pedal 43, electric clutch pedal 42, it is automatically controlled that entire car controller 100 controls clutch actuating mechanism 22 to separate
Clutch 21, manual transmission 31 are switched to climbing gear, and driver unclamps electric clutch pedal 41, stepping on accelerator pedal 42,
Entire car controller 100 controls the moment of torsion and rotating speed of driving motor 11 by electric machine controller 12, and vehicle is in climbing process.Driving
The person of sailing is hung up during hill gear climbed to stepping on accelerator pedal 42, and the rotary transformer of driving motor 11 can detect electricity
The direction and angle that machine rotor rotates, electric machine controller 12 is by judging rotor rotation direction and advance rotor direction phase
Instead, judge that vehicle is in and slip by slope state, so that the control driving motor 11 of electric machine controller 12 applies advance moment of torsion, prevent vehicle from sending out
Life slips by slope.
By using the hand gear control system and control method of the present invention for electric automobile, by driving electricity
Mechanical, electrical control clutch and manual transmission are combined, by controlling electric clutch pedal to complete to become to driving motor and manually
Fast case is connected and disconnected from, and the active force that driver steps on tradition machinery clutch has been dramatically reduced, has reduced driver's
Labor intensity, meanwhile, entire car controller carries out real-time, interactive, accurate control by gathering a variety of input signals, with electric machine controller
The rotating speed and torque output of system driving motor.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can readily occur in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
