Fig. 2 is electric vehicle a kind of detailed description of the invention of subsidiary engine drive system provided by the present invention
Structured flowchart.
This subsidiary engine drive system includes above-mentioned auxiliary machine driver, also includes controller 17, control
Device 17 processed is able to receive that turn signal and brake signal.Turn signal may come from and is arranged at
Monitoring rotation direction sensor in steering system, brake signal may come from brake pedal position sensing
Device, according to steering mode (automatically controlled or non-automatically controlled), the difference of mode of braking, can select phase
The signal pickup assembly answered, is specifically referred to prior art and understands.Controller 17 receives and turns
First clutch the 141, second clutch is controlled according to following control strategy when signal and brake signal
The action of device 142:
A, receive brake signal, do not receive turn signal:
Output closes the first clutch 141 of air compressor machine 12 side, separates power-assisted steering pump 13 side
The instruction of second clutch 142, makes dual-axle motor 11 outfan be connected with air compressor machine 12, twin shaft electricity
Machine 11 drives air compressor machine 12 to work, and air compressor machine 12 drives vacuum booster pump 15 action, vacuum servo
Pump 15 drives arrestment mechanism, plays braking function；Now, second clutch 142 separates, the most separately
One outfan disconnects with power-assisted steering pump 13, and power-assisted steering pump 13 does not works；
B, receive turn signal, do not receive brake signal:
Output closes the second clutch 142 of power-assisted steering pump 13 side, separates air compressor machine 12 side
The instruction of first clutch 141, makes dual-axle motor 11 outfan be connected with power-assisted steering pump 13, double
Spindle motor 11 drives power-assisted steering pump 13 to work, and hydraulic oil is delivered to power-assisted by power-assisted steering pump 13
Oil cylinder 16, plays turning function；Now, first clutch 141 separates, and another outfan is with empty
Press 12 disconnects, and air compressor machine 12 does not works；
C, receive turn signal and brake signal:
Output Guan Bi the first clutch 141 of air compressor machine 12 side, the second of power-assisted steering pump 13 side
The instruction of clutch 142, makes two outfans of dual-axle motor 11 connect air compressor machine 12 respectively and help
Power steering pump 13, simultaneously drives the two and rotates, turn to and braking function to play simultaneously；
D, do not receive turn signal and brake signal:
Output separate the first clutch 141 of air compressor machine 12 side, the second of power-assisted steering pump 13 side
The instruction of clutch 142, makes two outfans of dual-axle motor 11 turn with air compressor machine 12 and power-assisted respectively
Disconnecting to pump 13, air compressor machine 12 and power-assisted steering pump 13 run out of steam, and do not work, twin shaft electricity
Machine 11 dallies.
Above-mentioned electric vehicle auxiliary machinery device and auxiliary system have the following technical effect that:

Driven this air compressor machine to work by electromotor under engine mode, under electric model, start motor and drive
Dynamic another air compressor machine work, to save energy consumption.And in the present embodiment, under clutch effect,
Dual-axle motor 11 can be with tick over, either engine mode or electric model, energy consumption
The least, therefore without arranging the subsidiary engine driving in a set of air compressor machine, the i.e. present invention again on electromotor
Device or drive system, on the premise of guarantee reduction energy consumption, only arrange a set of air compressor machine,
And without distinguishing engine mode and electric model when controlling, control cost and be able to the most further
Reduce.
In order to improve the response speed of clutch quick-make or separation, two in above-described embodiment
Individual clutch is preferably electromagnetic clutch, and controller 17 direct signal of auxiliary system connects first
Clutch 141 and second clutch 142, the Guan Bi of automatically controlled two clutches or separation.When
So, it is also possible to be hydraulic control clutch, response speed can also meet use demand, now, control
Device 17 processed controls Guan Bi or the separation of clutch by the break-make of oil circuit control.
Controller 17 can be the entire car controller of electric vehicle.For electric vehicle, vehicle
On entire car controller typically can be set, be used for receiving, store, analyze various information of vehicles, and
Export multiple instruction, control the normal traveling of car load.Two can will be arranged on this entire car controller
Individual output stitch, respectively output control first clutch 141, second clutch 142 separate or
It it is the instruction of Guan Bi.Meanwhile, in control strategy (this control that entire car controller inner setting is predetermined
System strategy ensures that two clutches are according to tetra-kinds of situation work of above-mentioned a, b, c, d), then car load control
Device processed can control the action of two clutches.It is so designed that, it is not necessary to be separately provided control two clutches
The controller 17 of device, saves hardware；And, entire car controller is generally possible to collect braking letter
Number and turn signal, directly utilize the signal of collection, it is not necessary to separately set circuit, thus simplify
System structure.
For the various embodiments described above, during type selecting, air compressor machine 12 and power-assisted steering pump 13 specified
Rotating speed can be equal, and the rated speed that herein equal is not limited to the two is essentially equal, it is possible to
Being roughly equal.So, dual-axle motor 11 drives air compressor machine 12 and power-assisted steering pump 13
Time, the rotating speed of dual-axle motor 11 can be set as consistent with the rated speed of the two, during work,
Dual-axle motor 11 rotates according to this setting speed always, it is not necessary to turning dual-axle motor 11
Speed is controlled, and i.e. without arranging converter, then controls cost relatively low.
In above-described embodiment, the torque capacity of dual-axle motor 11 is more preferably greater than air compressor machine 12 and helps
The torque capacity sum of power steering pump 13, with ensure dual-axle motor 11 under any operating mode, all
Can successfully drive air compressor machine 12 and power-assisted steering pump 13 action.It addition, dual-axle motor 11
Power should be sufficiently large, with meet simultaneously drive air compressor machine 12, power-assisted steering pump 13 with volume
Determine rotary speed working.
It should be noted that in above-described embodiment, brake power parts are air compressor machine 12, by sky
Press 12 drives vacuum power pump 15 action, and then drives arrestment mechanism action.It is contemplated that
According to braking requirement and the difference of signals of vehicles, brake power parts can also be that other can carry
For the element of power, such as type brake of surging, the pump housing directly drive, now the pump housing
For brake power parts, then the outfan of dual-axle motor 11 can connect this pump by clutch
Body.
Except above-mentioned electric vehicle auxiliary machinery device, auxiliary system, the present invention also provides for a kind of electronic
Vehicle, including main drive system and vehicle subsidiary engine drive system, vehicle subsidiary engine drive system is upper
State the vehicle subsidiary engine drive system described in any embodiment.Owing to above-mentioned subsidiary engine drive system has
Above-mentioned technique effect, the electric vehicle with this subsidiary engine drive system also has identical technology effect
Really, here is omitted.
Above a kind of electric vehicle provided by the present invention and auxiliary machine driver thereof, subsidiary engine are driven
Dynamic system is all described in detail.Specific case used herein to the principle of the present invention and
Embodiment is set forth, and the explanation of above example is only intended to help to understand the present invention's
Method and core concept thereof.It should be pointed out that, for those skilled in the art,
Under the premise without departing from the principles of the invention, it is also possible to the present invention is carried out some improvement and modification,
