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 status data; Second step, system converts the situation of mood to the situation of automobile, and is detected the mood of owner by sensor at one time; 3rd step, system creation is based on the interactive strategy of automobile and people both sides' mood; 4th step, system starts people's car interactive exchange or order corresponding to corresponding chaufeur.
Fig. 2 and Fig. 3 describes the relation between neurotransmitter and basic emotion.It is relevant with quantity with the type of neurotransmitter inside human body which kind of mood people experiences.Neurotransmitter except swaying the emotion, also transmission of information between brain and health different parts.。
Neurotransmitter has many types, and can be classified as " stimulation " or " suppression " two type substantially, they can mate in pairs with special receptor and produce certain mood.Excitatory neurotransmitter stimulates brain causing more to enliven (but differ establish a capital be active mood).Such as adrenaline is exactly good a kind of excitatory neurotransmitter, and it is often relevant with palpitating speed with vivaciously optimistic personality.Another kind of excitatory neurotransmitter is dopamine, be to participate in eating people, motion or appointment etc. like movable time discharge.Except mood, memory, study and attention are also by the impact of these neurotransmitters.
The implementation method detailed step that a kind of people's car is mutual:
The first step obtains vehicle status data
The first step of this scheme, it is the vehicle mechanical state that acquisition one group may be used for expressing vehicle mood, system always monitors vehicle mechanical situation, the health status of collecting mechanical parts and the safety factor of present situation, this can be recorded into a characteristic, and the element of characteristic comprises oil mass, engine speed, tire pressure and other multidimensional information.Vehicle-state detects and mainly comprises following aspect: detect machine oil, machine filter, belt tension and situation, igniting, toe-in, storage battery situation, refrigeration system pipeline and joint, front brake plate, front brake disc and clamp, various fluid, tire pressure and situation (comprising spare tyre), light and device, each functional switch, door handle and each cleaning elements, interchanging of tires, ABS system manipulation device, paint damage and vehicle body status, detect driving situation (noise, stability, instrumentation situation), engine coolant, evaporative emission control system, rear brake plate, dish and clamp, airfilter, fuel oil filter, light-up plug, automatic wave box oil, manual device cylinder processed and lining, manual device operating control processed, sprung parts, exhaust system and situation, idling and idle exhaust emission CO value, tierod bulb, steering box and dust protecting cap, servo-steering function, pipeline and joint, valve lash, oil delivery pipe of oil tank and joint, brake piping, transfer line and ABS system.Vehicle condition feature is defined as
F h＝{F h1，F h2，F h3…F hn}
Wherein, n is the dimension of feature.Consider that different characteristic elements is different on the impact of vehicle condition, adopt different weights to quantize the impact of different element, its summation is 1.
a = { a i | Σ 1 n a i = 1 }
Second step converts vehicle-state to emotional state and detects chaufeur mood
Sub-step 1: convert the vehicle-state monitored to automobile emotional state
This step goes out safety factor according to the health calculations of mechanical component during current driving performance, and this coefficients conversion is become the emotional state of automobile according to mood mapping mechanism.Safety factor computing formula is as follows:
C s = Σ 1 n a i F hi
C sbe safety factor;
We calculate the safety factor of current operation status, and in this step, we set multiple threshold value to divide the grade of safety factor, we according to safety factor for user provides early warning information and suggestion.
One-level: the safe class first order
If safety factor is lower, as 0.2, that means the no good cake of the situation of vehicle, and driver must address this problem at once, so vehicle mood should be very anxious.Such as, when moving velocity quickly and tire pressure low cause wear on tyres very serious situation occur time, this is very dangerous, so vehicle mood must be very anxious.
Secondary: the safe class second stage
If safety factor normal (such as, its value is less than 0.5), that means the health status of mechanical component and bad, so chaufeur must draw attention to this situation, thus vehicle mood should be compare worry.
Three grades: the safe class third stage
If safety factor higher (such as, its value is between scope 0.5 ~ 0.8), that means that the health status of mechanical component is fine, so vehicle mood should become steady.
Level Four: the safe class fourth stage
If safety factor high especially (such as, its value is greater than 0.8), that means that the health status of mechanical component is very good, so vehicle mood should be very delight.
Sub-step 2: detect chaufeur mood
This step, by the mood of monitoring chaufeur, determines the mood that automobile should export.The mood monitoring of people is a very proven technique, and the present invention adopts common Expression Recognition, or monitors the mood of chaufeur based on the method that neurotransmitter in body is monitored.The present invention is not limited to these two class methods to monitor the mood of chaufeur, and other similar methods also can adopt.
Such as, three monoamine neurotransmitter serotonins that we can measure, dopamine and noradrenaline usually 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 neurotransmitters, 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, and therefore, the interactive strategy that system should configure should be taken into account the emotional status of chaufeur.That is, if chaufeur is very angry, what kind of the situation regardless of automobile mood is, automobile all should exchange with people with the gentle tone.The strategy of Systematic selection automobile mood is as shown in table 1.
Table 1: mood selection strategy
We can also carry out configuration interactive strategy in a more accurate way, that is, utilize the value of automobile mood and chaufeur mood to calculate configuration mood.The function definition calculating configuration mood is as follows:
Mc＝(w1Mv+w2Md)*δ
Mc is configuration mood, and Mv is the mood of automobile, and Md is the mood of chaufeur, w1 and w2 is the weight of automobile mood and chaufeur mood respectively, and δ is an adjustment function that the value of Mc can be converted to collocation strategy mood.Adjustment function also can consider the impact of chaufeur personality simultaneously.Such as, the personality of chaufeur is very 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 in configuration, mood determines, system call or synthesize corresponding sound and start talk, or the order of chaufeur that response is identified by the speech recognition system of complexity.In the present invention, automobile adopts the mood of the natural language processing technique analysis car owner of existing maturation.The many dialogues of different state values according to vehicle mood can be in systems in which preset, and the beginning of talk can be divided into two kinds of situations: initiatively and passive.In a first scenario, automobile reminds his owner owner requests to make corresponding operation, or the mood of automobile perception chaufeur also replys owner energetically.In this case, talk can be preset according to different sights.In another case, chaufeur request performs an order, and automobile needs the intention putting or confirm owner in order, and what it can be passive starts dialogue.
