TECHNICAL FIELD 
       [0001]    The invention relates to the field of electromotion mixed dynamic vehicle; especially the motor drive and generation control tech in electromotion mixed dynamic vehicle, particularly in the electric/generating multiplex controlling technology. 
       BACKGROUND OF THE INVENTION 
       [0002]    In recent years, in order to alleviate the tension of energy and worsening environment in mobile area, the study of new electromotion mixed dynamic vehicle of “energy-saving”, “environmental protection” has become a must trend. The so-called “hybrid electric”, is the multiplex of electric and other engines: when the mobile stars speeds up, it will use the permanent magnet synchronous motor/excitation motor as the multiplex motor to achieve the multiplex function of starting/electric power-assist; when the vehicle is slowing down or running normally, the permanent magnet synchronous motor/excitation motor will be used as the generator to achieve the energy feedback and charge to the battery. 
         [0003]    The conversion of starting, electric power-assist and generating operating status needs a series of drive controlling technology to achieve, and there are many new problems and tech difficulties in achieving the drive controlling technology and hybrid mobile developing process. 
         [0004]    For example: when the mobile starts in a low speed and high-speed power-assist according to automobile operating mode need, it needs a relatively higher electric torque, but the design theory of permanent magnetic motor limits the synchronous achievement of the low-speed starting the high torque and high-speed power-assisted the high torque. For example, under the same condition, the permanent magnetic motor at the rated speed of 800 r/min, its starting speed is much larger than the rated speed of 3000 r/min, but it cannot reach the high-speed power-assist due to its highest speed limit by the starting winding back electromotive force; the torque of the permanent motor designed as the rated speed of 3000 r/min is very small though it has a high torque power-assist in the high speed area. In other words, the permanent magnetic motor, which is designed as the low-speed starting requirement, cannot satisfy the functional need of power-assist in the high-speed area; while the permanent magnetic motor designed as the high-speed power-assist function cannot satisfy the need of the low-speed starting performance; and the contradiction between them cannot be negotiated. 
         [0005]    For example: Nearly all the current low voltage/generating multiplex controlling tech adopts to the lower tube voltage-drop of MOSFET device or model to achieve the low voltage permanent magnetic brushless motor drive control. While the function of MOSFET power device is low voltage of heavy-current tube or model, for example: the working voltage of the power tube or model with 200 A-600 A is usually 150V, but the maximum working currency of 300V-600V tube or model is merely tens of ampere. Therefore, in the low-voltage/generating multiplex controlling system, it can only adopts to the heavy-current MOSFET tube or model. Then after the finish of the mobile electric working status, the engine can go into the generating condition naturally; and no matter if there is load or not in the generation output, the back electromotive power-assist will rise as the speeding up, which will lead to a higher back electromotive power-assist in the electric winding, and the back electromotive power-assist produced by it will be much higher than the normal voltage of the MOSFET tube or model. Taking the example of mobile 42V electric/generating multiplex apparatus system: 42V refers to the charging voltage in motor is 42VDC, the battery voltage adopted is safe voltage of 36V; the back electromotive power-assist of electric winding of the permanent synchronous motor designed as voltage of 36V, rating speed of 800 r/min is nearly 36V when working; however, the back electromotive power-assist of the one of 800 r/min can achieve more than 200 V under 6500 r/min, which is much higher than the minimal working voltage of MOSFET tube or model, damaging the MOSFET tube or model directly. So currently, in order to avoid the problems of the permanent magnetic 42V electric/generating multiplex apparatus system, many mobile producers, both in and out of China, still adopts to the excitation magnetic 42V electric/generating and its control system, though its torque and efficiency is inferior to the one in permanent magnetic synchronous motor. 
         [0006]    Moreover, there will be two batteries and generating charging system in vehicle, no matter adopting to the high voltage or low voltage hybrid system; take the above 42V system for example, it comprises the two batteries of 12V, 36V and two generating charging systems of 14V and 42V Currently, the implementation of two batteries and generating charging system in most mobile companies adopts to this method: adopting to one generating and charging system to provide one kind of battery charging and/or loading electricity directly; to the generating charging system, it will use DC-DC to boost or drop the voltage, providing battery charging of another voltage and/or loading electricity. This method costs much and is low efficiency; especially for the DC-DC of high power, low voltage; and the controlling system of DC-DC has a tough tech problem, its designing cost is nearly one brushless permanent magnetic motor drive controlling system. 
         [0007]    According to the tech difficulties above, nowadays, most of the various mobile companies adopts to the high-voltage hybrid system, that is a higher voltage battery, and the higher tube voltage, larger currency IGBT model to realize the motor drive control system, as well as adopt the permanent synchronous brushless sine wave motor and its weak magnetic drive controlling system; the weak magnetic drive controlling system, which adopts the weak magnetic way, can not only run the high torque in a low-speed starting, but also achieve the electric high-speed power-assist of the motor; accordingly, when the stator winding is stated in d axis, the weak magnetic controlling principle is to add the currency to generate the homo-polarity magnetic fields from stator field and relative rotator permanent magnetic, which will reduce the strength of the rotator permanent magnetic to achieve the goal of increasing the speed and control the output. However, the weak magnetic controlling is inclined to generate the electric rotator permanent demagnetization, and the requirement for circuit design is very high. Once there is something wrong with the circuit, the back electromotive power-assist will set all the controlling system on fire; and the motor will always exist the current input of weak magnetic, the temperature in motor will rise and be hot, which not only consume the energy, but also has the disadvantages of low efficiency, lots of problems, drop output torque, etc.

         [0049]    As showed in  FIG. 3 , in this invention, the first case of dynamo electric multiplex system adopts: one permanent brushless synchronous motor drive controller, the controller is composed of controlling circuit, drive circuit ( 120 ), and three-phrase rating drive circuit ( 110 ); one star permanent brushless synchronous motor ( 200 ) connecting with many contacts, this motor ( 200 ) comprises starting winding ( 210 ) U 1 , V 1 , W 1  and the motor assistant winding ( 220 ) U 2 , V 2 , W 2 ; one of three-phrase heavy-current double magneto electric switch ( 300 ); one 14V low-voltage rectifier chopper regulating circuit ( 410 ) and one 42V high-voltage rectifier chopper regulating circuit ( 510 ). 
         [0050]    The detailed is as followings: the system adopts to one of low-voltage 12V battery ( 420 ) and one of high-voltage battery ( 520 ), which is composed of MOSFET drive model by the rating tube T 1 , T 2 , T 3 ? T 4 , T 5 , T 6 , that is three-phrase rating drive circuit ( 110 ); the positive of the high voltage battery ( 520 ) connects the positive input of the MOSFET model. The A. B. C output in the three-phrase MOSFET drive model connects with the U 1 , VI, W 1  in the starting winding ( 210 ) or U 2 , V 2 , W 2  in the motor assistant winding switch ( 220 ) via the three-phase heavy-current double magneto electric ( 300 ) separately.

Thus the rectifier chopper regulating circuit ( 410 ,  510 ) will on the dynamic balance with the stable output voltage of 14V and 42V. 
         [0054]    Based on the electric generating multiplex controlling system, it can increase the controlling function, that is to integrate the motor drive controller ( 110  and  120 ), high-low voltage rectifier chopper regulating circuit ( 410 ,  510 ), whole vehicle controlling and generator ECU controlling.

The motor chip will calculate the signals above and control the magneto electric switch signal according to the working status; output signals of motor drive circuit can run, start/stop, regulation; output the signals of generating voltage regulating circuit; send out the signal of motor ECU when lack of oil or electricity signal. 
         [0058]    The starting, electric power-assist and the double-voltage generating output is in the status of closing, when it runs, the high-low voltage rectifier chopper regulating circuit ( 410 ,  510 ) is in the status of non-output status. When the mobile generator does not need electric working status, for example, the mobile is running or decelerating normally, the two rectifier chopper regulating circuit ( 410 ,  510 ) is in the status of output. The mutual working status model can increase the dynamic when mobile is starting or accelerating.

         [0066]      FIG. 5  is structural diagram of the outer shell of the controller, among it:  1 —outer shell;  2 —effusion groove;  3  heat-dissipating liquid; A—sealing covering;  5 —sealing covering bolt;  6 —O-type sealing ring;  7 —fuel bolt;  8 —sealing pad;  9 —heat-dissipating plates;  10 —models;  11 —model fixing bolt;  12 —shell fixing hole. 
         [0067]    In the existing tech, normally the drive controller adopts to the heat-dissipation via air-cool or water-cool. In the hybrid with the electric working status, the controller can adopt to the air-cool or water-cool, but in the short time, it has a relative higher cost. 
         [0068]    Therefore, the invention particularly designs one simple and practical heat-dissipating shell. There is one effusion groove ( 2 ) in the outer shell ( 1 ), the effusion groove ( 2 ) has the heat-dissipating liquid ( 3 ) with high heat, the sealing covering ( 4 ) of the heat-dissipating liquid ( 3 ) connects with sealing of the outer shell ( 1 ), the sealing covering ( 4 ) can be the model fixing pad, the model ( 10 ) is fixed on the pad ( 4 ) of the heat-dissipating liquid covering. 
         [0069]    In order to add the heat-dissipating liquid ( 3 ) conveniently, the outer shell ( 1 ) has one hole in the fuel bolt ( 7 ) to connect with the effusion groove ( 2 ). 
         [0070]    In order to increase the effect of heat-dissipation, there is a heat-dissipating plate ( 9 ) in the outside wall of outer shell ( 1 ) and the inside wall of the effusion groove. The model ( 10 ) is fixed on the covering pad of the heat-dissipating sealing, which can absorb the heat produced by the starting or electric power-assist in short time, it will be absorbed by the heat-dissipating liquid, and the dissipates through the outer shell ( 1 ). 
         [0071]    What should be mentioned is that, the inventive content and the detailed 
         [0072]    operation method is to demonstrate the practical application of the invention, but not for the limit of the protection range. The tech stuff can do various modification, exchanging or combination under the spirit and the principle of the invention. The protective range should conform with the requirement.
