Along with the development of science and technology, automatic control technology is also more and more employed in people's daily life, and the automobile of automatic transmission, also gets more and more.At present, the car of automatic transmission also uses the technology of automatic gear selecting, but there is following shortcoming, and motor cannot realize operation meticulous especially, and reaction speed is manually not sensitive, and this also causes comparing excessive fuel consumption, economical not.Existing automatic transmission system gear selecting process speed is slow, and noise is comparatively large, and gear selecting needs precision high, operation energetically, and the car of existing automatic transmission all also exists problem in these areas.
Summary of the invention
The object of the invention is to overcome the reaction of existing automatic gear automobile sensitive not, the problem of accurate operation cannot be realized.
For this reason, the invention provides a kind of gear selecting based on AMT system manipulation assembly, comprise a microcontroller and gear selecting control assembly CPU, for receiving the instruction of being sent by communication bus by the main core CPU of gear selecting, gather the hall signal of brushless electric machine and the angle signal of actuator, and send instruction to control bridge Drive and Control Circuit; One bridge Drive and Control Circuit, for controlling power driving circuit; One power driving circuit, for exporting the control signal of brushless electric machine, to control brushless electric machine; One actuator, for completing the operation of gear selecting; One current signal collecting unit, for gathering the current information in power driving circuit, sends microcontroller to; One angle signal collecting unit, for gathering the position signal of actuator, sends microcontroller to; The hall signal collecting unit of one brushless electric machine, for gathering the hall signal of brushless electric machine, and sends microcontroller to.
The above-mentioned manipulation of the gear selecting based on AMT system assembly, described bridge drive circuit and power driving circuit carry out pumping source and power.
The above-mentioned manipulation of the gear selecting based on AMT system assembly, described gear selecting main core CPU is the main nuclear control CPU of gear selecting of automobile AMT electrical autocontrol system.
Beneficial effect of the present invention: this manipulation of the gear selecting based on AMT system assembly provided by the invention, although adopt pumping source to power, cost is higher, also but its control accuracy higher is high for circuit, software programming complexity, safe and reliable automatic operation system is brought compared to the automobile for running at high speed, very to one's profit; Should based on the gear selecting manipulation assembly of AMT system, not only can do the high-power motion of low speed, as locked in motor power down, motor, electric machine rotation, motor speed can be realized control, the simple motion modes such as motor self-locking moment of torsion control, also the compound movement modes such as such as variable force motion, step motion, uniform motion, single step campaign can be realized, should based on the gear selecting manipulation assembly of AMT system, mainly use the high-power motion of low speed, control accuracy is high, the power stepping on gear selecting is very large, and loose gear selecting wants the motions such as slow pine.
Below with reference to accompanying drawing, the present invention is described in further details.
Accompanying drawing explanation
Fig. 1 is the gear selecting manipulation assembly schematic diagram based on AMT system.
Embodiment
Embodiment one:
The manipulation of the gear selecting based on AMT system assembly as shown in Figure 1, comprise a microcontroller and gear selecting control assembly CPU, for receiving the instruction of being sent by communication bus by the main core CPU of gear selecting, gather the hall signal of brushless electric machine and the angle signal of actuator, and send instruction to control bridge Drive and Control Circuit; One bridge Drive and Control Circuit, for controlling power driving circuit; One power driving circuit, for exporting the control signal of brushless electric machine, to control brushless electric machine; One actuator, for completing the operation of gear selecting; One current signal collecting unit, for gathering the current information in power driving circuit, sends microcontroller to; One angle signal collecting unit, for gathering the position signal of actuator, sends microcontroller to; The hall signal collecting unit of one brushless electric machine, for gathering the hall signal of brushless electric machine, and sends microcontroller to.
When should work based on the gear selecting manipulation assembly of AMT system, the instruction that the main core CPU of gear selecting is sent by communication bus controls assembly CPU to gear selecting, gear selecting controls assembly CPU and gathers the current hall signal of brushless electric machine, determine current shift-selecter information, then according to current shift-selecter information, send instruction and control bridge Drive and Control Circuit, bridge drive control circuit power driving circuit, power driving circuit exports the control signal to brushless electric machine, thus control actuator completes gear selecting operation, in the process, gear selecting controls assembly CPU, still gather the hall signal of collection brushless electric machine, and the current signal of power driving circuit, can Real-Time Monitoring, the operation of whole process.
