Detailed description of the invention
Fig. 1 describes the overall framework of this scheme.This scheme is made up of four parts, the first step, and we obtain vehicle Machine performance data;Second step, system is converted into the situation of emotion the situation of automobile, and is examined by sensor in the same time Survey the emotion of owner;3rd step, system creation is based on automobile and the interactive strategy of people both sides' emotion;4th step, system starts people Car interactive exchange or the order that driver is corresponding accordingly.
Fig. 2 and Fig. 3 describes the relation between neurotransmitter and basic emotion.People experiences inside which kind of emotion and human body The type of neurotransmitter is relevant with quantity.Neurotransmitter is in addition to swaying the emotion, also between brain and health different parts Transmission information..
Neurotransmitter has many types, generally can be classified as " stimulation " or " suppression " two types, and they can be with specific Receptor mates in pairs and produces certain emotion.Excitatory neurotransmitter stimulates brain causing more to enliven (but to differ to establish a capital and be Active mood).Such as epinephrine is exactly good a kind of excitatory neurotransmitter, it often with the most optimistic personality and the heart Jump quickening relevant.Another kind of excitatory neurotransmitter is dopamine, is to participate in eating people, move or appointment etc. like movable time Discharge.In addition to emotion, remember, learn and attention is also affected by these neurotransmitteies.
The implementation method detailed step that a kind of people's car is mutual:
The first step obtains vehicle mechanical status data
The first step of this scheme, is to obtain one group of vehicle mechanical state that may be used for expressing vehicle emotion, and system is total Being to monitor vehicle mechanical situation, the health status of collecting mechanical parts and the safety coefficient of present situation, this can be recorded into one Characteristic, the element of characteristic includes oil mass, engine speed, tire pressure and other multidimensional information.Vehicle mechanical state-detection master Following aspect to be comprised: detection machine oil, machine filter;Belt tension and situation, igniting, toe-in, storage battery situation, refrigeration system pipeline and Joint, front brake(-holder) block, front brake disc and clamp, various fluid, tire pressure and situation (including spare tyre), light and device, each Functional switch, catch and each cleaning elements;Tire rotation, ABS system manipulation device, paint damage and vehicle body status;Detection Driving situation (noise, stability, instrumentation situation), engine coolant, evaporative emission control system, rear brake(-holder) block, dish And clamp, air filter, fuel filter, spark plug, automatic wave box oil, manual device cylinder processed and lining, manually device processed behaviour Vertical device, sprung parts, gas extraction system and situation, idling and idle exhaust emission CO value, track rod bulb, turn to machine and dust-proof Set, power-assisted steering function, pipeline and joint, valve clearance, oil delivery pipe of oil tank and joint, brake piping, transfer pipeline and ABS system System.The definition of vehicle mechanical state feature is
Fh={ Fh1, Fh2, Fh3...Fhn}
Wherein, n is the dimension of feature.Different on the impact of vehicle mechanical state in view of different characteristic elements, use Different weights quantify the impact of different element, and its summation is 1.
a = { a i | Σ 1 n a i = 1 }
Vehicle mechanical State Transferring is become emotional state and detects driver's emotion by second step
Sub-step 1: the vehicle mechanical State Transferring monitored is become automobile emotional state
This step goes out safety coefficient according to the health calculations of machine components during current driving performance, and reflects according to emotion This coefficient is converted into the emotional state of automobile by the mechanism of penetrating.Safety coefficient computing formula is as follows:
C s = Σ 1 n a i F h i
CsIt is safety coefficient;
We calculate the safety coefficient of current operation status, and in this step, we set multiple threshold value to divide safety The grade of coefficient, we provide the user early warning information and suggestion according to safety coefficient.
One-level: the safe class first order
If safety coefficient is relatively low, such as 0.2, that means the no good cake of situation of vehicle, and driver must solve this at once Individual problem, so vehicle emotion should be the most anxious.Such as, tire wear is caused when travel speed is very fast and tire pressure is low When the most serious situation occurs, this is extremely dangerous, so vehicle emotion must be the most anxious.
Two grades: the safe class second level
If safety coefficient normal (such as, its value is less than 0.5), that means the health status of machine components not Good, so this situation must be drawn attention by driver, thus vehicle emotion should be to compare worry.
Three grades: the safe class third level
If safety coefficient higher (such as, its value is between scope 0.5~0.8), that means machine components Health status is fine, so vehicle emotion should become steady.
Level Four: the safe class fourth stage
If safety coefficient the highest (such as, its value is more than 0.8), that means the health status of machine components very It is good, so vehicle emotion should be very delight.
Sub-step 2: detection driver's emotion
This step, by monitoring the emotion of driver, determines the emotion that automobile should export.The emotion monitoring of people is one The most ripe individual technology, the present invention uses common Expression Recognition, or method based on the monitoring of nerves within the body mediator is monitored and driven The emotion of the person of sailing.The invention is not limited in this two classes method to monitor the emotion of driver, other similar methods can also Use.
Such as, three monoamine neurotransmitter 5-hydroxy tryptamine that we can measure, dopamine and noradrenaline are usually counted Calculate the emotional state of user.Along with the fast development of human biological's sensor, we can inside and outside at human body, around integrated low Power, miniaturization and intelligentized sensor node monitor these neurotransmitteies, just as wireless body area network (WBNS) and HRS-I。
3rd step configuration interactive strategy
Based on general knowledge, the mankind occupy leading position in people's car interaction, therefore, and the mutual plan that system should configure Slightly should be taken into account the emotional status of driver.If it is to say, driver is the most angry, how the situation regardless of automobile emotion is , automobile all should exchange with people with the gentle tone.The strategy of Systematic selection automobile emotion is as shown in table 1.
Table 1: emotion selection strategy
We can also carry out configuration interactive strategy in a more accurate way, say, that utilizes automobile emotion and driver The value of emotion calculates configuration emotion.The function calculating configuration emotion is defined as follows:
Mc=(w1Mv+w2Md) * δ
Mc is configuration emotion, and Mv is the emotion of automobile, and Md is the emotion of driver, w1 and w2 is automobile emotion respectively and drives The weight of the person's of sailing emotion, δ is an adjustment function that can be converted to the value of Mc configure strategy emotion.Adjustment function is the most also It is considered that the impact of driver's personality.Such as, the personality of driver is the most genial, and the intonation that automobile uses in talk also can More enliven agile.
It is mutual that 4th step starts people's car
After configuration emotion determines, system is called or is synthesized corresponding sound and starts talk, or response is by complexity The order of the driver that speech recognition system identifies.In the present invention, automobile uses the natural language processing technique of existing maturation Analyze the emotion of car owner.Different state value many dialogues according to vehicle mood can preset in systems, the beginning of talk Two kinds of situations can be divided into: actively and passively.In the first scenario, automobile reminds his owner owner requests to make accordingly Operation, or the emotion of automobile perception driver reply owner energetically.In this case, talk can be according to different Sight is preset.In another case, driver asks to perform an order, and automobile needs to put in order or confirm the intention of owner, It can be passive start dialogue.
