Specific embodiment
Core of the invention is to provide a kind of electric automobile two-shift automatic variable speed control device, is operated with simplifying.Additionally, this
Another core of invention is to provide a kind of electric automobile with above-mentioned electric automobile two-shift automatic variable speed control device.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in Figure 1-Figure 3, the invention discloses a kind of two grades of automatic shifting controllers of electric automobile, it includes passing through
Vehicle speed sensor 3 obtains the rotating speed of the output shaft of two speed transmission 4, and the gear for obtaining two speed transmission 4 by gear position sensor 2 is believed
Breath, gearshift controller 1 is judged according to the rotating speed and gear information that obtain, when the speed for obtaining is mismatched with the gear for obtaining
When gearshift controller 1 control two speed transmission 4 switch over operation.Pass through vehicle speed sensor 3 and gear position sensor 2 in the application
The rotating speed of the output shaft of two speed transmission 4 and the gear information of two speed transmission 4 are obtained respectively and judge two by gearshift controller 1
Whether person is matched and the control method in carrying out gear shift operation, i.e. the application when mismatching is realized using sensor and controller
The process of self shifter, solves the cumbersome of artificial gearshift, simplifies operation.
In practice, gear information matches with speed and refers to：If the real-time speed of electric automobile is less than setting speed, two grades
Speed changer 4 is driven in high ratio, i.e. high transmission ratio；If the real-time speed of electric automobile is more than setting speed, two speed transmission 4
In low speed than transmission, i.e. underneath drive ratio.The gearratio of the two speed transmission 4 in the application is the transmission of input shaft and output shaft
Than.
As shown in Fig. 2 when the gear information for obtaining is mismatched with speed, if the real-time speed of electric automobile is more than or equal to
Setting speed and two speed transmission 4 be in high transmission ratio when, that is, mismatch, then controller for shifting 1 perform upshift program：Gear shift control
Device processed 1 drives gear shifting motor 5 to operate, and motor makes two speed transmission 4 switch to underneath drive ratio from high transmission ratio.
As shown in figure 3, when less than setting speed, two speed transmission 4 is in underneath drive ratio to the speed for obtaining, i.e., not
Match somebody with somebody, then gearshift controller 1 performs downshift program：Gearshift controller 1 drives shift motor 5 to operate, and motor makes two grades of speed changes
Device switches to high transmission ratio from underneath drive ratio.
In further embodiment, the gear position sensor 2 also obtains the control gearshift behaviour of two speed transmission 4 of gearshift controller 1
Gear information after work, and the gear information of acquisition is sent to gearshift controller 1, whether the gearshift controller 1 judges gearshift
Success, if shift gears it is unsuccessful if gearshift controller 1 control two speed transmission 4 continue shift gears and default n times shift gears after still not into
Work(then stops gearshift.Whether the 1 pair of gearshift of gear position sensor 2 and gearshift controller in the application successfully judges, so as to protect
Demonstrate,prove the stability of gearshift.
Core in the application is the current vehicle speed for gathering the rotating speed on the output shaft of two speed transmission 4 as vehicle, to sentence
It is disconnected whether needing gearshift, in practice, can also judge as auxiliary information with reference to the angle information of gas pedal be
It is no to need gearshift.Specifically, on the output shaft of two speed transmission 4 rotating speed, the angle information of gas pedal and two speed transmission 4
Gear information compare jointly interpretation whether need gearshift.The angle information of the gas pedal in the application only helps out,
Whether gearshift is needed for two speed transmission 4, what is played a decisive role is the rotary speed information on the output shaft of two speed transmission 4.
In further embodiment, in two grades of automatic shifting controllers of the electric automobile, also including warning device, should
Warning device receives the control signal of gearshift controller 1, and detects the unsuccessful letter for stopping gearshift of gearshift in gearshift controller 1
Alarm is sent after breath.Setting warning device can offer operator and vehicle is tieed up in time when two speed transmission 4 has failure
Repair.Type of alarm for warning device can use any-mode, such as jingle bell or light.
