As distortion embodiment, as shown in Figure 14 and Figure 16, this Vehicular turn operating control also comprises electrical motor 8 and is located at minisize pick-up head 54 and the driver's license recognizer 55 on bearing circle 5, the motor shaft 82 of electrical motor 8 is connected with the drive link 76 on the 3rd steering shaft 7 by magnetic clutch 10, minisize pick-up head 54, driver's license recognizer 55 and magnetic clutch 10 are connected with the control system of vehicle, control system receives the signal of minisize pick-up head 54 and driver's license recognizer 55, the combination of controlling magnetic clutch 10 with separate.
The casing 81 of electrical motor 8 is for being arranged on vehicle, all stretch out from casing 81 at the two ends of motor shaft 82, one end of motor shaft 82 is connected with drive link 76 by magnetic clutch 10, drive link 76 is coaxial with motor shaft 82, the other end of motor shaft 82, as actuating force mouth, can be connected with the deflector of steering swivel system.Magnetic clutch 10 is combinations for controlling drive link 76 and motor shaft 82 and separate, and realizes transmission and the interruption of moment of torsion, and magnetic clutch 10 is connected with the control system on vehicle, the control of controlled system.When magnetic clutch 10 in conjunction with time, electrical motor 8 no powers, motor shaft 82 can freely rotate under the driving of drive link 76, output actuating force.
Minisize pick-up head 54 and driver's license recognizer 55 are arranged on bearing circle body 51, minisize pick-up head 54 is also connected with the control system of vehicle with driver's license recognizer 55, minisize pick-up head 54 is the head portraits for gathering driver, driver's license recognizer 55 is for gathering the people information on driver's license, minisize pick-up head 54 and driver's license recognizer 55 are also passed to control system by the information collecting, control system receives the signal of minisize pick-up head 54 and driver's license recognizer 55, the combination of controlling magnetic clutch 10 with separate.In the time that vehicle uses, when driver injects key, driver's license is put on driver's license recognizer 55, now minisize pick-up head 54 can carry out face scanning to driver, and the people information on driver's head portrait and driver's license that control system can gather minisize pick-up head 54 contrasts, if comparing result is consistent, control system control magnetic clutch 10 combinations, drive link 76 is engaged with motor shaft 82, and now driver's usable direction dish 5 is controlled wheel flutter, and realization turns to; If comparing result is inconsistent, magnetic clutch 10 not combinations, in stays.
Adopt above-mentioned setting, reach the control transmission of actuating force and the object of interruption by controlling the combination and separating of magnetic clutch 10, can prevent that car is stolen on the one hand, without pinning bearing circle with handle lock, only have driver's information correctly could bring into play the function of vehicle completely, can prevent from the other hand driving without a license, avoid person without license's steering vehicle, guarantee driving safety.
In the time that magnetic clutch 10 separates, electrical motor 8 can be used as normal motor and uses, and in the time that electrical motor 8 is switched on, only motor shaft 82 rotates the power driven deflector running producing, and this kind of setting can be used as new hand and learn car assisted diversion.Concrete, on bearing circle 5, the voice recognition unit being connected with control system can also be set, its radical function is to send control system to by changing into different electric signal after acquisition of signal determined by fate sound different Driving Instructor, and voice command signal has: bearing circle turns left, bearing circle is turned right and bearing circle does not turn.When Driving Instructor is during real vehicle training driver person apprentice, if apprentice misroutes bearing circle, Driving Instructor can pass through the voice command direct control bearing circle of oneself, makes apprentice's steering wheel operating ineffective.For example, when apprentice misses bearing circle to anticlockwise, Driving Instructor can say " bearing circle right-hand rotation " at once, now voice recognition unit changes into corresponding electric signal by this voice command signal and sends control system to, control system is exported control signal immediately to magnetic clutch 10 after receiving this signal, magnetic clutch 10 disconnects, drive link 76 is separated with motor shaft 82, thereby make the bearing circle input of chaufeur inoperative, simultaneously, control system control electrical motor 8 turns round, and produces power export through motor shaft 82 by electrical motor 8, realizes wheel flutter and turns right; When automobile does not need to turn to, and when apprentice's steering wheel rotation, Driving Instructor says " bearing circle does not turn " at once, now voice recognition unit changes into corresponding electric signal by this voice command signal and sends control system to, control system receives and exports immediately control signal after this signal is that magnetic clutch 10 disconnects, thereby make the bearing circle input of chaufeur inoperative, meanwhile, make automobile not occur turning to thereby control system output control signal maintains static it to electrical motor 8; When apprentice misses bearing circle to right rotation, Driving Instructor can say " bearing circle left-hand rotation " at once, now voice recognition unit changes into corresponding electric signal by this voice command signal and sends control system to, control system receives and exports immediately control signal after this signal is that magnetic clutch 10 disconnects, thereby make the bearing circle input of chaufeur inoperative, meanwhile, thus control system output control signal makes its unidirectional rotation that wheel flutter is turned left to electrical motor 8.
Below by reference to the accompanying drawings the present invention is exemplarily described.Obviously, specific implementation of the present invention is not subject to the restrictions described above.As long as having adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; Or without improvement, above-mentioned design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
