The control method of electromagnetic continuously variable transmission device of the present invention is：
The first step：Above-mentioned electromagnetic continuously variable transmission device is installed to engine；
Second step：When selection parking or neutral gear, automobile gears control unit controls first, second torque servo-driver to close operation, the interaction moment of torsion of the first rotor is zero in first motor, the stator of second motor is applied to bitrochanteric moment of torsion equal to zero, realizes engine and outer load isolation；Meanwhile, automobile gears control unit goes to run on the signal of idling or stalling signal to control unit of engine hair, and engine runs on idling or directly stalling.Or, when selecting reverse gear, automobile gears control unit notifies engine economical operation main control unit that the torque setting of the first torque servo-driver is adjusted into zero, simultaneously, machine winding is changed into being connected in series entirely by segment control unit by switch arrays, and automobile gears control unit receives the angle signal sent from gas pedal upper angle sensor, it is become to the torque setting signal for turning to the second torque servo-driver, control the second motor output reverse-drive torque.Or, when selecting drive shift, gear signal is sent to the units such as the second torque servo-driver, engine economical operation main control unit, segmentation controller by automobile gears control unit, now, driver step on the throttle pedal when, control unit of engine will control engine operating.The engine speed that engine economical operation main control unit is measured according to First Speed/position sensor, according to the engine optimal economic operation curve prestored, by the first torque servo-driver control the first motor to engine apply torque loads so that engine be operated in it is most economical in the state of.While the first torque servo-driver controls the first motor to apply torque loads to engine, an equal amount of moment of torsion is directly sent to output shaft driving automobilism by the first motor.At the same time, the unnecessary kinetic energy from engine is converted into electrical energy transportation to dc bus by the first motor.So, due to the injection of energy, busbar voltage is to be lifted.When busbar voltage monitoring and the detection of PID control unit
To after this voltage increase, its internal PID control unit will export corresponding torque setting to the second torque servo-driver of output, and the second torque servo-driver controls the driving torque of the second motor and the common externally output driving motor racing of the first motor.When driver steps on the throttle acceleration, engine will export more kinetic energy, first motor is foretold at load-side sunset except portion of energy is penetrated into, more energy will be had it is converted into electric energy and delivers to bus unit, busbar voltage is monitored and PID control units will stabilize the rising of busbar voltage by improving the second motor driving torque, and improving the second motor driving torque can cause automobile to accelerate.When the desired rotating speed of speed arrival driver, driver maintains this throttle, and automobile enters stable speed operation；When speed exceedes desired rotating speed, driver unclamps throttle, so that alternator speed is reduced, the energy that first motor penetrates into load is accordingly reduced, electric energy into bus will decrease, busbar voltage is monitored and PID control unit will control the second motor to reduce external driving energy, so that fall-back.When the second motor third trochanter velocity of rotation reaches predetermined value, segmentation controller can real-time controlling switch array, the connection in series-parallel form of adjustment armature winding.When automobilism is in low speed, winding is coupled in series, it is necessary to during high pulling torque, driver output maximum current, it is ensured that good power performance.When automobilism is in high speed, winding is connected with parallel form, it is necessary to which when running at high speed, driver output current vector change frequency is improved, it is ensured that good speed ability.Due to winding switch speed quickly, switching time is usually no more than 0.2 second, thus can realize insentience switch, while the regulation continuous variable of motor torque, so ensures that good speed regulation performance.Or, when selecting hill gear, segmentation controller controlling switch array, armature winding is adjusted to cascade so that under maximum output torque under the second motor unit driving current, this state, in addition to winding type of attachment, situation when other control methods are with selection drive shift is identical.
According to the one side of the control method of the electromagnetic continuously variable transmission device of the present invention, when automobilism needs high pulling torque to drive in low speed, winding is to connect, star form connection；When automobilism is in the small moment of torsion of high speed, winding is connected with parallel, triangular form.
According to the other side of the control method of the electromagnetic continuously variable transmission device of the present invention, in order to be unlikely to the frequent switching of switch arrays occur when surveying speed change near predetermined switching point, Schmidt's control is added in above-mentioned switching, i.e. raising speed when need to be raised to some more than predetermined speed value and just implement winding switching, some value below predetermined speed need to be dropped to during reduction of speed just to switch back, the window size of Schmidt's characteristic is determined according to actual conditions, is compromised between ensureing switching point sensitivity and preventing switch arrays frequent switching and is chosen.
, need to be corresponding before and after switching action to ensure that saltus step does not occur for the second motor output torque before and after switching according to the other side of the control method of the electromagnetic continuously variable transmission device of the present invention
Change the torque setting ratio of busbar voltage monitoring and PID control unit to the second torque servo-driver.
Just it is blunt according to the present invention electromagnetic continuously variable transmission device control method another aspect, it can also be moved backward using the scheme control of speed closed loop, accelerator pedal angle signal is back-up speed setting signal during reversing, with the accurate control back-up speed in the range of safe speed.

Automobile gears control unit is whole electromagnetic continuously variable transmission device control axis, includes driving switch and speed change main control unit composition.Driving switch is accustomed to setting according to conventional car steering, point parking, reversing, neutral gear, advance, several grades of climbing, the state feeding speed change main control unit of driving switch.Speed control unit controls engine economical operation main control unit, the first and second torque servo-drivers of control, segment control unit according to accelerator pedal angle and busbar voltage, and then controls the output of dynamical system.
The gas pedal of the present apparatus is needed to increase pedal angle sensor in traditional mechanism, and the angle signal of gas pedal is sent into automobile gears control unit and control unit of engine.
The control method of electromagnetic continuously variable transmission device of the present invention is：
The first step：Engine installs above-mentioned electromagnetic continuously variable transmission device；
Second step：When selection parking or neutral gear, automobile gears control unit 17 controls the first torque servo-driver 10 and the second torque servo-driver 16 to close operation, the interaction moment of torsion of first motor first rotor 6 and the second rotor 7 is zero, the moment of torsion that the stator 11 of second motor is applied to the second rotor 12 is equal to zero, realizes engine and outer load isolation；Meanwhile, automobile gears control unit 17 goes to run on the signal of idling or stalling signal to the hair of control unit of engine 1, and control engine 3 runs on idling or directly stalling.
3rd step：When selecting reverse gear, automobile gears control unit 17 notifies engine economy
The torque setting of first torque servo-driver 10 is adjusted to zero by operation main control unit 4, meanwhile, the second machine winding is changed into being connected in series entirely by segment control unit 18 by switch arrays 19, the series connection Y-connection of connection method as shown in Figure 5；Refer to Fig. 9 busbar voltage detection and PID control unit control principle block diagrams, in reverse gear, the torque setting signal for sending into the second torque servo-driver 16 through automobile gears control unit 17 from busbar voltage detection and PID control unit 14 is cut off, automobile gears control unit 17 receives the angle signal sent from the upper angle sensor of gas pedal 2, it is carried out to the torque setting signal after ratio processing as the second torque servo-driver 16, control the second motor output reverse-drive torque.It is assumed that servo-driver output maximum current is constant, and using motor output torque during triangle connection method in parallel as 1, moment of torsion is the moment of torsion no-load voltage ratio that 3.464, i.e. reverse gear realize 3.464 times during series connection Y-connection, and in upper fan's change, the motor feels hot, and state is constant.More than 1.5 times of sort time overcurrent ability can be typically left in view of driver, so causes that excursion expands as 5 times or so to moment of torsion in short-term again.The second motor is switched to large torque low speed motor under state of rolling backward, it is ensured that the power and safety of reversing.
Speed is better controled over during in order to move backward, the scheme of back-up speed closed loop can also be used, see Figure 10, accelerator pedal angle signal is back-up speed setting signal during reversing, rate setting signal carries out asking poor with the output shaft speed signal that speed/positional sensor 15 is measured, then the torque setting after PID computings as the second torque servo-driver 16.Appropriate pid parameter can be such that back-up speed is accurately controlled in the range of safe speed.Velocity close-loop control can also be realized using other automatic control technologys.
4th step：When selecting drive shift, automobile gears control unit I7Gear signal is sent to the second torque servo-driver 16, engine economical operation main control unit 4, segment control unit 18, now, driver step on the throttle pedal 2 when, control unit of engine 1 by control engine 3 operate.The engine speed that engine economical operation main control unit 4 is measured according to First Speed/position sensor 5, according to the engine optimal economic operation curve prestored, the moment values of correspondence present engine rotating speed on the curve are tried to achieve, corresponding torque setting signal is applied to the first torque servo-driver 10.The rotor relative position signal of the first motor first, second that first torque servo-driver 10 is tried to achieve according to this setting signal and according to First Speed/position sensor 5 and second speed/position sensor 15 conveys current phasor by three-phase slip-ring 8 to the first armature winding, make the first motor by its first rotor 6 to engine apply torque loads so that engine be operated in it is most economical in the state of.While first motor first rotor 6 applies torque loads to engine, an equal amount of moment of torsion is directly sent to output shaft driving automobile by the second rotor 7
Operation.At the same time, first motor is under the driving of the first torque servo-driver 10, part kinetic energy from engine is converted into electrical energy transportation to dc bus by pump energy mode, or the electric energy from dc bus is changed into mechanical energy is superimposed upon on output shaft and drive automobilism.So, due to electric flux injection or take, busbar voltage it is to be lifted or reduction.Such as Fig. 9 busbar voltage detection and PID control unit control principle block diagram, after busbar voltage monitoring and PID control units 14 detect busbar voltage, measurement voltage and the busbar voltage set-point pre-set are asked poor, carry out sending into automobile gears control unit 17 after PID arithmetic again, signal is directly over normally closed switch therein and sends into the second torque servo-driver 16, the second motor third trochanter position signalling that the torque servo-driver 16 of the mat woven of fine bamboo strips two is measured according to this setting and second speed/position sensor 15 controls the current phasor of the second motor, make the second motor third trochanter 12 to output shaft output driving moment of torsion.Because the second motor third trochanter 12 with the first motor second rotor 7 is coaxial connection, then in this case, the driving torque of the common externally output driving motor racing of two motors.
When driver steps on the throttle acceleration, engine 3 is by raising speed, engine economical operation main control unit 4 is given to the first torque servo-driver 10 in the same way according to the current rotating speed of engine applies corresponding torque setting signal, first torque servo-driver 10 conveys current phasor to the first armature winding in the same way according to this setting signal, make the first motor by its first rotor 6 to engine apply torque loads so that engine be still operated in it is most economical in the state of.Because engine 3 is by raising speed, first motor is foretold at load-side sunset except portion of energy is penetrated into, more energy will be had it is converted into electric energy and delivers to dc bus and energy-storage units 13, busbar voltage is monitored and PID control unit 14 will improve the second motor driving torque by PID arithmetic, so that automobile raising speed consumes more electric energy to stabilize the rising of DC bus-bar voltage, it engine output kinetic energy, the first motor is directed through energy, the first electric power generation, the second motor and new energy balance is issued in higher speed.When speed rotating speed desired more than driver, driver unclamps throttle so that engine speed is reduced, and the electric energy into bus will decrease, busbar voltage is monitored and PID control unit 14 will control the second motor to reduce external driving energy, so as to realize speed stabilizing or fall-back.
When vehicle actual motion state in output shaft be the second rotor speed be higher than the first rotor when, first motor and the first torque servo-driver, which need to take electric energy from dc bus, to be converted into kinetic energy and adds on output shaft, this can cause busbar voltage to reduce, now busbar voltage monitoring and D control units 14 will reduce the second motor driving torque by PID arithmetic, even allow the second motor to export reactive torque and enter Generator Status, kinetic energy on output shaft is transformed back into electric energy again, the decline of busbar voltage is stabilized.Now because the second motor exports reactive torque, output shaft is sent to
The driving torque of load declines, and the speed of car finally falls after rise, so that fall-back realizes that busbar voltage is balanced, or forces driver to open the throttle to realize speed stabilizing to lift engine output.
When the velocity of rotation of the second motor third trochanter 12 reaches Discrete control predetermined value, the real-time controlling switch array 19 of the meeting of segmentation controller 18 adjusts the connection in series-parallel form of armature winding, specific as follows：
As shown in Fig. 5 to Fig. 8, the connection method of the machine winding of the present embodiment second has：Series connection Y-connection；Serial triangle is connected；Parallel in planetary is connected；Triangle connection in parallel.It is assumed that servo-driver output maximum current is constant, and using motor output torque during triangle connection method in parallel as 1, moment of torsion is 1.732 when then parallel in planetary is connected, moment of torsion is 2 when serial triangle is connected, moment of torsion is 3.464 during series connection Y-connection, i.e., switched using connection in series-parallel, realizes maximum 3.464 times change in torque, and in above-mentioned change, the motor feels hot, and state is constant.More than 1.5 times of sort time overcurrent ability can be typically left in view of driver, so causes that excursion expands as 5 times or so to moment of torsion in short-term again.And the mechanical no-load voltage ratio of one grade to five grades of 1.8 liters of engines of embodiment is only 4.526 times.When the controlling switch array 19 of segmentation controller 18 carries out the switching of armature winding connected mode, to ensure that saltus step does not occur for the second motor output torque before and after switching, the torque setting ratio of busbar voltage monitoring and 14 pair of second torque servo-driver 16 of PID control unit need to accordingly be changed before and after switching action, such as, when being switched to series connection Y-connection from serial triangle connection, driver exports an equal amount of output current, second motor output torque can increase to switching before 1.732 times, therefore it is uncomfortable to avoid driving caused by torque mutation, must be in 1/1.732 before torque setting value to be instantaneously changed into switching for switching.
Servo-driver output ceiling voltage is changeless, and the adjustment of any speed can not all make the back-emf of motor break through the limitation of maximum output voltage.It is assumed that using connect Y-connection method when motor maximum no-load speed as 1, maximum no-load speed is about 1.732 when then serial triangle is connected, maximum no-load speed is about 2 when parallel in planetary is connected, maximum no-load speed is about 3.464 during triangle connection in parallel, switched using connection in series-parallel, realize up to about 3.464 times of speed regulation.On this basis, control method of the invention also introduces weak magnetic speed-up technology, and raising speed scope is expanded into 1.4 times or so again so that speed adjustable range is expanded to 4.8 times, more than mechanical 4.526 times of the no-load voltage ratio of one grade to five grades of 1.8 liters of engines of embodiment.
By the unloaded specially fast list of highests of the above-mentioned Fig. 5 to the winding construction shown in Fig. 8 under bus rated voltage, in this, as the predetermined value of switching winding, when the velocity of rotation of the second motor third trochanter 12 reaches predetermined value, segmentation controller 18 can real-time controlling switch array 19, the connection in series-parallel form of adjustment armature winding.
In order to be unlikely to the frequent switching of switch arrays occur when surveying speed change near predetermined switching point, Schmidt's control should be added in above-mentioned switching, i.e. raising speed when need to be raised to some more than predetermined speed value and just implement winding switching, some value below predetermined speed need to be dropped to during reduction of speed and is just switched back.The window size of Schmidt's characteristic is determined according to actual conditions, is compromised between ensureing switching point sensitivity and preventing switch arrays frequent switching and is chosen.
According to foregoing description, when automobilism is in low speed, winding is coupled in series, and driver, which exports same electric current, can obtain bigger moment of torsion.When needing high pulling torque, driver output maximum current, it is ensured that hybrid electric vehicle has good power acceleration.When automobilism is in high speed, winding is connected, it is necessary to when running at high speed with parallel form, driver output current vector alternative frequency is improved, on the premise of maximum output voltage is constant, motor speed can be improved, it is ensured that hybrid electric vehicle has good speed ability.Because the switch speed of winding is generally less than
0.2 second, thus can realize that insentience switches, while the regulation continuous variable of motor torque, so ensures that good speed regulation performance and ride comfort.Each phase winding of the motor of the present embodiment second is 2 groups, can be also made up of more windings, broader moment of torsion and speed no-load voltage ratio can be realized according to same control method.
5th step：When selecting hill gear, armature winding is adjusted to Y-connection of connecting by the controlling switch array 19 of segmentation controller 18, so that output torque is maximum under the second motor unit driving current, under this state, in addition to winding type of attachment, other control methods are identical with the 4th step.
