The present invention also provides a kind of voices for above-mentioned knob automobile shift system to wake up recognition methods comprising
Following steps: then acquisition driver's audio signal carries out data prediction to the audio signal, extracts the feature in the data
Word is waken up, feature is waken up into word and is compared with the default wake-up word in template library, if consistent, recognition result activates language
Sound function.And driver preset in advance spy can wake up word in the template library of automobile.
In order to which the present invention is further described, it is exemplified below more detailed embodiment and is illustrated.
Knob automobile gear shift system includes voice wake-up module 1, phonetic order module 2, body information feedback module 3, rotation
Button electromagnetic lock module 4, knob position detection module 5, lamplight pointing module 8, long-range shift module 7 and shift decision-making module 6.
Voice wake-up module 1 wakes up phonetic function of the word to activate switchgear by saying feature.It effectively prevent missing
It says manipulation instruction word, such as D gear, vehicle is caused accidentally to be shifted gears, so each instruction must reawake.
Phonetic order module 2, when phonetic function is waken up, phonetic order module 2 starts to detect and identify the voice of user
Instruction, and carry out corresponding function operation.Its function is as follows: 1, by phonetic order can direct gear shift operation, be mainly used in and work as
It can still shift gears when knob damages.2, by phonetic order lockable or unlocking knob, it is mainly used to the spin-ended button of parking rear defence
It is misused.Phonetic order possesses highest priority, but because its accuracy of identification is by noise effect, should not be as main shift hand
Section, is mainly used as alternative scheme.
Body information feedback module 3, velocity information, gear information, the brake information of Real-time Feedback vehicle.Wherein gear is believed
Breath is fed as input to lamplight pointing module 8.Velocity information, brake information are supplied to knob electromagnetic lock module 4.
Knob electromagnetic lock module 4 occurs security risk to prevent knob maloperation, has installed electromagnetic lock additional below knob
Device.It is not stepped on when detecting to brake, when speed is not 0, knob electromagnetic lock is activated, and electromagnetic attracting device is attracted, and lock pin blocks
Knob, prevent knob is from being rotated.It is stepped on when meeting brake simultaneously, when speed is 0, knob electromagnetic lock can just be unlocked.In addition,
Phonetic order can be used to lock or unlock by force when a failure occurs it.
Knob position detection module 5 the disadvantages of electromagnetic induction knob low precision, is used since contact knob is easy to wear
The higher photo-electric knob of reliability.Knob position detection module mainly passes through detection photosignal, and then judges knob position,
Issue corresponding shifting commands.Knob increases Auto gear on the basis of existing gear, supports pilotless automobile, and if only if
When Auto gear is activated, just remote auto is allowed to put into gear.
Lamplight pointing module 8, because knob cannot judge current shift information by feel, using different colours lamp
Light indicates current shift information, enhances user experience.
Long-range shift module 7, i.e. automatic Pilot shifting commands, the module be used to receive sended over from CAN bus it is remote
Journey shifting commands, and pass it to shift decision-making module
Shift decision-making module 6 summarizes phonetic order, knob instruction and long-range shifting commands, preferential by a series of logic judgments
Grade sequence, and select the high instruction of priority and be sent to gearbox shifting.
