Description
Technical field
The invention belongs to automobile intelligent trip industry control system manufacturing technology field and control method technical field, specifically
Ground is said, is related to a kind of vehicle audio input control system and control method for intelligent travel.
Background technology
It improves with the continuous development of society, intelligent travel increasingly attracts attention, while also receives each intelligence and grind
Study carefully the extensive concern of mechanism and automobile industry." Chinese moment " rate of being expected to of global intelligent travel arrives first.December 20 in 2017
Day, first council of Apollo smoothly holds in Xiong Anxinqu.The council is made of internet and vehicle enterprise, entire by formulating
The general orientation of Apollo ecology overall strategies, and development, the management of discussion city unmanned vehicle jointly, push relevant laws and regulations, political affairs
Reproducible, propagable unmanned pattern model is sought in the formulation of plan.
" intelligent vehicle " of the prior art, exactly increased on the basis of common vehicle advanced sensor (radar,
Camera shooting), controller, the devices such as actuator, pass through vehicle-mounted sensor-based system and information terminal realize that the intelligence with people, vehicle, road etc. is believed
Breath exchanges, and vehicle is made to have intelligent environment sensing ability, can automatically analyze the safety and precarious position of vehicle traveling, and makes
Vehicle is arrived at according to the wish of people, final to realize the purpose for substituting people to operate.By to Vehicular intelligent technology
Research and development, can improve control and the driving ability of vehicle, and support vehicles travel safe and smooth, efficient.To intelligence
Vehicle control system constantly study and improve, be equivalent to extension and extend control, vision and the sensory function of driver, can pole
The earth promotes the safety of road traffic.
The vehicle of intelligent travel of the prior art is realized people's vehicle interaction intercommunication, is reached mostly by the way of phonetic entry
The purpose and effect of intelligent travel.But in the vehicle audio input process in existing intelligent travel field, due to the prior art
In phonetic entry using unified, single phonetic entry, will certainly cause input content with driver's expression content not
The complete moment is consistent, it is impossible to accurately realize that man-machine intercommunication is interactive, the comfort of vehicle is caused to substantially reduce；Especially language
Sound input is related to safe driving when the order of critical fielies, if cannot accurately identify and transmit signal to vehicle ECU, can also
Major safety risks are brought, traffic accident will be led to when serious.
Invention content
Of the invention to use unified, single phonetic entry since vehicle audio inputs in the prior art for solution, nothing is entangled
Wrong and nucleus correcting system, will certainly cause the incomplete moment of input content and driver's expression content to be consistent, it is impossible to accurate
The man-machine intercommunication of realization it is interactive, the comfort of vehicle is caused to substantially reduce；Major safety risks can be also brought when serious, lead to vehicle
Misfortune.The present invention is to overcome the technical solution of above-mentioned technical problem, provides a kind of vehicle audio for intelligent travel and inputs control
System and control method processed, technical solution of the present invention are capable of providing error correction and nucleus correcting system in addition to phonetic entry, ensure language

8. a kind of vehicle audio input control method for intelligent travel according to any one in claim 1-7,
It is characterized in that, the auxiliary language control system (7) includes pattern pulse variation storage processor corresponding with word, when described
Pattern pulse variation storage processor corresponding with word receives image change pulse signal, starts internal database, by described
Pattern pulse variation storage processor internal logic calculation process corresponding with word, will store information with connecing in internal database
The external information of receipts compares and analyzes, and forms externally the second word pulse signal of output.
9. a kind of vehicle audio input control method for intelligent travel according to any one in claim 1-8,
It is characterized in that, logic comparison storage processor is equipped in the central control module (8), the logic comparison storage processor
The first word pulse signal and the second word pulse signal are separately or concurrently received, the logic comparison storage processor will
It receives the first word pulse signal and the second word pulse signal intersect and checks comparison：
Step 1, when the first word pulse signal and the second word pulse signal comparing result meet preset value, then by center
Control module (8) output performs signal；If result is less than preset value, two are entered step；
Step 2, when the first word pulse signal and the second word pulse signal comparing result are less than preset value, then main speech
The corresponding voice messaging of the first word pulse signal is reported in output module (4) output, and driver is asked to confirm yes/no；If confirm
It is that the corresponding execution signal of the first word pulse signal is then exported by central control module (8)；If confirmation is no, enter
Step 3；
Step 3, when the first word pulse signal and the second word pulse signal comparing result are less than preset value, then main speech
The corresponding voice messaging of the second word pulse signal is reported in output module (4) output, and driver is asked to confirm yes/no；If confirm
It is that the corresponding execution signal of the second word pulse signal is then exported by central control module (8)；If confirmation is no, enter
Step 4；
Step 4, the vehicle audio input control system of the intelligent travel stop this instruction operation, this instruction ignore.
