Electro-motor 16 can be to have brush or brushless DC motor.Under the background of vehicle application, some application examples of electro-motor 16 include petrolift, bellows and cooling fan and for driving automatic lock for bicycle, vehicle window, fuel tank cap or door, exhaust gas recirculatioon (EGR) control, automatic tuned absorber (ATK), the selective catalytic reduction system operating of diesel vehicle and the motor of electric parking brake, the most only list.In FIG, electro-motor 16 is shown to have two different motors: have brush DC motor and brushless DC motor, but this mean onlys that the viewpoint showing that universal control unit may be used for driving any motor type.Such as in vehicle is applied, universal control unit 10 may be connected to a kind of motor type or another kind, but is not attached to the two.Can use any number of suitable electro-motor, various including Continental, Coavis, Bosch and Delphi Company have brush and brushless DC motor.Because having brush and the general structure of both brushless DC motors and operation is well known in the art and because any number of suitable motor type may be used for universal control unit depicted herein, so having had been left out the specific explanations to these motors.The electro-motor embodiment in addition to listed above can also be used, including following brushless motor: have more or less than three-phase (the most biphase brushless DC motor)；(in-runner), outer turn of (out-runner) or other kinds of known setting is turned in having；Or there is Delta/triangle (delta), Y-shaped or other kinds of known wiring configuration or topology.

Turning now to the operation of universal control unit, Fig. 4 includes brush operator scheme and Fig. 5 relates to brushless operator scheme.There is multiple possible mode to determine which kind of operator scheme is suitable in control unit.Such as, during fabrication, software and/or hardware setting, sign or other designators can be configured to indicate which kind of motor algorithm is processing means 12 should run, as reached in the case of algorithm is all stored in electronic memory 22 two breeds of horses.If only a kind of motor algorithm is stored in memorizer, the most such setting can be unnecessary.In different examples, processing means 12 automatically determines universal control unit and is connected to which kind of motor type and correspondingly selects suitable motor algorithm.It is of course possible to use other technologies.

Start from there is brush operator scheme 100 shown in Fig. 4, it is shown that the mode of operation of six illustrative switch 50-60 in output stage 14 and be sent to brush the electric current of DC motor 16.In having brush operator scheme 100, processing means 12 performs brush motor algorithm, and it controls high side/flash (high-side in an interleaved manner; And downside/low limit (low-side HS); LS) switch (phase 110-114) is to there being brush DC motor to provide electric current (drawing 120).(from time t during the initial part of the first phase 110₀To t₁), high-side switch 50 is in "ON" and remains switch 52-60 and be in "Off", in order to electric current flows from power supply 70 winding in brush DC motor 16 by switch 50, node 62, output connection 80, stitching section 90 and arrival.(from time t during the recycle sections of the first phase 110₁To t₂), high-side switch 50 is transferred to "Off" and low side switch 52 is transferred to "ON" so that the energy that the electric current in motor is continuing with being stored in motor inductance flows by means of recirculation path.This path includes motor 16, by ground wire 72, low side switch 52, node 62, output connection 80, stitching section 90 and the winding returning motor.

After the first phase 110, the initial part of the second phase 112 is (from time t₂To t₃) start from high-side switch 54 and forward "ON" to and remain switch and forward "Off" to.As mutually, this causes electric current to flow by switch 54, node 64, output connection 82, stitching section 90 and the winding having brush DC motor from power supply 70.And, this operation electric current initially or leading to electro-motor 16 during the non-recirculated period in the second phase 112 increases.At time t3, high-side switch 54 forwards "Off" to and low side switch 56 forwards "ON" to so that the energy that the electric current in motor is continuing with being stored in motor inductance flows by means of recirculation path.This path includes motor 16, is returned by ground wire 72, low side switch 56, node 64, output connection 82, stitching section 90 and motor.About the initial of third phase 114 and recycle sections (respectively from time t₄To t₅With from time t₅To t₆) there is similar sequence of events, only electric current flows respectively by high side and low side switch 58 and 60.As just explained, at a time, the only one switch in the switch 50-60 in output stage 14 is transferred to "ON" or activation, and other switches are generally transferred to "Off".

The complete cycle of exemplary three-phase alternating series includes single phase 110-114 of all three and from time t₀To time t₆, at time t₆Described sequence starts again at.Use pulsewidth modulation (PWM) or other technologies well known by persons skilled in the art that dutycycle can be made change to change the quantity of power/electricity being supplied to electro-motor.The general power being supplied to brush DC motor 16 is the summation of three Partial Powers of offer in three each phases operated in phase 110-114 by high side and low side switch.Switching frequency is generally specified by electro-motor demand or specification.Skilled artisan will appreciate that the generation of above-mentioned interleave method is similar to tradition and has current waveform (drawing 120) produced by brush DC motor, but this is to use the brushless configuration improved to be realized.Brush DC motor is had to need not rotor-position probe algorithm, this is because this is realised mechanically in brush motor.

Universal control unit being previously described to the traditional mode being different from operation brush motor, in this traditional mode, electric current flowing switchs (single-phase) by list group in output stage, and does not interlock, as mentioned above between homophase.In another embodiment, two or more high-side switch 50,54,58 are forwarded to "ON" simultaneously, rather than replace the most exclusively, so that at the initial part of phase, electric current is flowed concurrently to be connected by multiple switches, node and output and arrives stitching section 90, and during recycle sections, electric current simultaneously flows through multiple low side switch and output connects arrival stitching section 90.Such as, all three high-side switch can be simultaneously in "ON", and all three low side switch is the most such.In different embodiments, output stage 14 only has biphase (rather than three-phase), and the method shown in Fig. 4 with above-mentioned staggered or noninterlace mode this two alternate alternately.

Fig. 5 shows brushless operator scheme 200, wherein controls high side and low side switch 50-60 by brushless motor algorithm, and this brushless motor algorithm is generally determined by the winding layout of brushless DC motor 16.Skilled artisan will appreciate that, any number of different commutation algorithm can be used for driving brushless DC motor, including motor depicted herein.In this concrete example, (from time t during the initial part of the first phase 210₀To t₁), high-side switch 50 and low side switch 56 are transferred to "ON", and rest switch is transferred to "Off".During the further part of the first phase 210, same high-side switch 50 remains on and low side switch 56 forwards "Off" to and low side switch 60 is activated.Such on off sequence continues in second and third phase 212 and 214, and note the situation avoiding same high side and low side switch (switch 50,52 in such as phase 40) simultaneously to forward "ON" to, because this will cause the short circuit between power supply 70 and ground wire 72.The average voltage on brushless DC motor can be changed by using pulsewidth modulation (PWM) technology high-side switch or driver (as understood by those skilled in the art) and therefore change motor speed.

Therefore, in the case of not producing research and development and manufacturing the expense of single motor controller, system by selecting suitable motor algorithm and can be made specific hardware improvement and drives or otherwise control have brush or brushless DC motor by universal control unit 10.Traditionally, needing two single motor controllers, one is used for brush motor, and one is used for brushless motor.
