Specific embodiments (is example with the electronlmobil)
1, make electronlmobil adapt to the changing road conditions of state of kinematic motion needs
As everyone knows, the rail vehicle have all adopted electric locomotive mostly.But because highway road conditions complexity, often run into hillside, bend, driving, pedestrian etc., the running state of motor often changes, the time and press the driving condition operation, the time and move by braking mode.And the most method for controlling number of revolution control motors that adopt of prior art move, when motor is in rotating speed control, in order to adapt to the state of kinematic motion that motor often changes, the output torque of motor alters a great deal, the torque rating of motor must could satisfy its need of work very greatly, and this is to be difficult to realize in actual applications.Therefore, only rely on electronlmobil less use on highway communication of speed control, be difficult to promote.
The invention scheme makes motor be in driving condition or braking mode all is to move under the output torque mode.Motor adopts the method for output torque control, because torque is controlled, as long as output torque is controlled in the motor torque rating, just can satisfy the requirement of automobile motor operation under different road conditions.Be the method for example explanation output torque control below with the AC induction motor:
For specific AC induction motor, at each rotary speed working point, its output torque depends on the slip of the power line voltage and the motor of motor, as long as that is to say the output torque that the voltage of having determined each rotating speed point and slip just can be determined each rotating speed point of motor.The method of the invention control output torque is: according to rotor speed and motor number of pole-pairs, change frequency, the control slip is with the collaborative voltage control motor torque of slip, the method that replaces used direct control motor speed makes electronlmobil adapt to complicated road conditions.Because torque is the exercising result of power, the state of kinematic motion of object is by external force vectorial sum decision, that is to say can carry out when torque that different power produces is on same object vector superposed.This shows that the effect that electronlmobil adopts the method for torque control to adapt to other external force is to be relatively easy to,, can make electronlmobil in operational process, adapt to the complex road condition that runs into by torque control.
2, improve electrical efficiency, increase the distance that charging electric vehicle once travels.
At present, increasing capacity of cell is to increase the distance that charging electric vehicle once travels, and improves once the travel main method of the shorter problem of distance of charging electric vehicle.
The invention promptly improves electrical efficiency by increasing unit quantity of electricity institute work, increases the distance that charging electric vehicle once travels, and improves the charging electric vehicle shorter problem of distance of once travelling.
Currently marketed AC induction motor all has an efficiency index, and in electronlmobil suitable power specification, when motor load was rated load, nominal load, its service efficiency was generally between 80%-90%; When load-rate of motor reduced, its service efficiency decreased.And the load of motor is constantly to change in the electronlmobil, in order to be no more than the motor rated load, nominal load, can only select the maximum load of power of motor greater than electronlmobil, therefore the load factor of motor usually tens percent, per centum, or even zero (zero load), the combined efficiency of motor very low (being commonly called as low load with strong power).
For specific AC induction motor, each rotating speed all has a cooresponding slip to make electrical efficiency the highest.During with slip and voltage Collaborative Control motor torque, make motor follow the peak efficiency slip of this motor/speed curves operation, by regulating voltage, controlling torque.Efficient when motor is worked in this case is higher, is higher than the work efficiency of traditional control method far away, thereby increases the distance that charging electric vehicle once travels.
On the other hand, electric automobile during traveling runs into complex road conditions such as bend, driving, pedestrian, uphill/downhill often, often needs braking.The glancing impact motor is in generating state, saves in the battery electric energy when becoming Drive for EV after the mechanical energy in the braking procedure is changed into electric energy and is rectified into direct current.Use the described method of the invention, electronlmobil is when braking mode, motor is in generating state, this moment, motor was controlled with torque, for particular motor, make it follow predefined peak efficiency slip/speed curves operation, by the regulating voltage controlling torque, most effective when making motor make electrical generator.The efficient that this method makes mechanical energy transform electric energy improves, thereby increases the distance that charging electric vehicle once travels.
3, a kind of double dynamical or application of many power coordinated operation pattern on electronlmobil or hybrid vehicle.
Automobile is with two or multiple electric motors controlling and driving, and this moment, motor was in the torque state of a control, the torque of motor output and be that total torque is to drive the torque that automobile needs.
With two or multiple electric motors through the motor combined action of the change speed gear box of different converter speed ratios or different rated speed of rotation in same dynamical axis, each motor is in the operation of torque mode, by the requirement of control convenience according to each operating mode torque of automobile, with the quality of each motor at each performance of operating condition, set the ratio of each motor output torque, make motor all in the big torque of speed stage output that oneself is fit to, thereby reach the purpose of two or multiple electric motors coordinated operation.The method of the invention control output torque is: according to rotor speed, change frequency, the control synchronous speed is regulated slip, with the collaborative voltage control motor torque of slip.Because torque is the exercising result of power, the state of kinematic motion of object is determined by the external force vectorial sum, that is to say can carry out when torque that different power produces is on same object vector superposed, this shows, the effect that a kind of double-motor or many motor powers system or other hybrid power systems adopt the method for torque control to adapt to other external force is to be relatively easy to, so, can solve the problem that electronlmobil and hybrid vehicle run in double dynamical or many power coordinated operation process by torque control.
4, the described motor torque control method of the invention, motor high-efficiency operation method also are applicable to tandem or parallel type hybrid dynamic automobile, and its control method is identical with above-mentioned Control of Electric Vehicles method, does not give unnecessary details at this.
