Referring to fig. 2, fig. 2 is a schematic flow chart of a method for preventing vehicle-sharing and driver-driver disputes according to a first embodiment of the present invention.

While a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than shown.

The method for preventing disputes among car owners of the network appointment car in the embodiments of the present invention is applied to a client for communicating with the internet outside the car on the network appointment car, and the client may be a mobile terminal, a vehicle-mounted terminal, a PC, a portable computer, or other terminal devices, and is not limited specifically herein.

The method for preventing the vehicle-booking and driver-and-passenger disputes in the embodiment comprises the following steps:

s100, collecting real-time dialogue voice among the drivers and passengers of the online taxi appointment;

the client side which is equipped with the intelligent car networking function on the network appointment car continuously collects real-time dialogue voice between a driver and a passenger (hereinafter referred to as a driver and a passenger for short) in the whole travel of the network appointment car.

It should be noted that, in this embodiment, the client may establish a connection with a communication network outside the network appointment car through a mature internet of things technology, so as to implement the function of the intelligent car networking. In addition, the client can continuously aim at real-time conversation voice among drivers and passengers in the online appointment car through a built-in or external microphone.

Specifically, for example, the client may be a certain vehicle-mounted terminal supporting a vehicle networking function on a car of the appointment, and the vehicle-mounted terminal is automatically turned on through information transmitted by sensors arranged on seats other than a current car driver seat of the appointment to collect real-time conversation voice generated among drivers and passengers in the car of the appointment.

It should be noted that, in this embodiment, the sensors disposed on the other seats may transmit corresponding information to the vehicle-mounted terminal when monitoring whether a passenger sits on the current seat, that is, when monitoring that the passenger sits on the current seat, the sensors immediately transmit a "passenger has got on the vehicle" information to the vehicle-mounted terminal, so that the vehicle-mounted terminal automatically starts to collect real-time conversation voice between drivers and passengers after receiving the information.

Further, in another possible embodiment, besides the vehicle-mounted terminal is automatically started, the vehicle-mounted terminal may be started based on receiving a command triggered by a driver or a passenger to collect real-time conversation voice between the drivers and the passengers, for example, after the driver of the networked car appointment starts to start the current formation by getting on the car, the vehicle-mounted terminal starts to continuously collect the real-time conversation voice generated between the drivers and the passengers in the networked car appointment by using a preset physical or virtual key on the vehicle-mounted terminal or by triggering and inputting a start command to the vehicle-mounted terminal based on a voice manner, so that the vehicle-mounted terminal starts to continuously collect the real-time conversation voice generated between the drivers and the passengers in the networked car appointment after receiving the start.

Step S200, inputting the real-time conversation voice into a preset driver and passenger dispute recognition model so that the driver and passenger dispute recognition model can recognize the real-time conversation voice and output a recognition result, wherein the driver and passenger dispute recognition model is obtained by carrying out federal learning training on a driver and passenger conversation sample according to a network appointment vehicle;

it should be noted that, in this embodiment, the client may combine with other clients and the server to form a federation, so that a federal learning training is performed on a network appointment car and driver-and-passenger conversation sample which is well collected and formulated based on the federation, so as to obtain a driver-and-passenger dispute recognition model, and thus disputes which may exist among drivers and passengers are recognized by using the driver-and-passenger dispute recognition model.

After acquiring real-time conversation voice among drivers and conductors, the client immediately takes the real-time conversation voice as model input and inputs the model input into a trained driver and conductor dispute recognition model, so that the driver and conductor dispute recognition model trains aiming at the model input to recognize the real-time conversation voice and output a recognition result capable of identifying whether dispute behaviors exist among the drivers and conductors.

Specifically, for example, the in-vehicle terminal establishes a connection with a trusted server together with other plural in-vehicle terminals, thereby forming a machine learning federation, and then the collected and formulated network appointment car driving conversation samples are used for carrying out federal learning training, so as to obtain a driving dispute recognition model which can recognize real-time conversation voice among drivers and passengers to accurately judge whether disputes exist among the drivers and passengers, therefore, the vehicle-mounted terminal can carry out the federal learning training in the whole journey of the network appointment car, after the real-time dialogue voice between the driver and the crew is acquired, the real-time dialogue voice is immediately input into the driver and crew dispute recognition model, and the driver and passenger dispute recognition model carries out model training calculation aiming at the real-time dialogue voice and outputs a recognition result which is obtained after the real-time dialogue voice is recognized and identifies whether disputes exist among the driver and passenger.

It should be noted that, in the present embodiment, the department dispute recognition model may be a speech recognition model mature in the industry, for example, the department dispute recognition model may specifically be DFCNN (deep full probabilistic neural network) and LAS (Listen Attend and speak, an LAS model established based on a neural network structure named "Listen Attend and speak"). It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the department dispute recognition model may also be different from other mature speech recognition models listed herein, and the method for stopping the network car-booking department dispute according to the present invention is not limited to the specific type of the department dispute recognition model.

And S300, if the identification result identifies dispute behaviors among the drivers and conductors, outputting a preset dispute stop prompt to stop the dispute.

The client inputs the acquired real-time conversation voice into the driver and passenger dispute recognition model, so that after the driver and passenger dispute recognition model recognizes the real-time conversation voice and outputs a recognition result, if the client detects that dispute behaviors exist among drivers and passengers identified by the recognition result, the client immediately inputs a preset dispute stop prompt to stop the dispute in time.

It should be noted that, in this embodiment, in the process of obtaining the driver-crew dispute recognition model by the client performing federal learning training in association with the machine learning federation established by other clients and the server, the driver-crew conversation sample adopted by the client includes a sample label for indicating that the conversation between the drivers is "good communication", or "communication obstacle exists", even "dispute behavior exists", and when the client trains the driver-crew dispute recognition model, the driver-crew dispute recognition model also performs learning training on the feature vectors of the corresponding driver-crew conversation sample based on the different sample labels, so that the driver-crew dispute recognition model recognizes the real-time conversation voice between the drivers and outputs the recognition result corresponding to the sample label of "good communication", "communication obstacle exists", or "dispute behavior exists", and then the result identification of the communication state between the driver and the passenger can be identified.

Further, in this embodiment, the dispute stop prompt is output in a voice and/or video broadcast manner to prompt the driver and the crew to execute a dispute emergency operation, where the dispute emergency operation includes an emergency video and/or an alarm.

Specifically, for example, the vehicle-mounted terminal as the client performs federal learning training in combination with other vehicle-mounted terminals to obtain the driver and crew dispute recognition model, and the digital identifiers 1, 2 and 3 corresponding to "good communication", "communication obstacle exists" and "dispute behavior exists" are respectively used as recognition results which may be output after recognizing the real-time conversation voice, so that if the vehicle-mounted terminal currently inputs the collected real-time conversation voice among the drivers and crew into the driver and crew recognition model, and the driver and crew recognition model performs model training calculation based on the real-time conversation voice to output a recognition result of "3", the vehicle-mounted terminal determines that the communication among the drivers and crew in the current network appointment car journey is dispute through the sample label of "dispute behavior" corresponding to the recognition result of "3", and thus, the vehicle-mounted terminal immediately outputs to the drivers and crew in the network appointment car through a voice broadcast manner that the video recording is to be executed urgently and is about to be performed The alarm prompt can frighten the drivers and the passengers so as to effectively stop disputes caused by communication among the drivers and the passengers in time.

Further, in another feasible embodiment, after the client inputs the collected real-time dialogue speech into the driver and passenger dispute recognition model, so that the driver and passenger dispute recognition model recognizes the real-time dialogue speech and outputs a recognition result, if the client detects that disputes do not exist among drivers and passengers identified by the recognition result, the client continues to continuously collect the real-time dialogue speech, and inputs the real-time dialogue speech into the driver and passenger dispute recognition model to recognize and output the recognition result.

Specifically, for example, if the vehicle-mounted terminal inputs the collected real-time dialogue voice between the drivers and the conductors into the driver dispute recognition model, and the recognition result of the driver and passenger dispute recognition model which is output by model training calculation based on the real-time dialogue voice is '1' or '2', the vehicle-mounted terminal determines that no dispute exists between the drivers and the passengers in the current network appointment journey through the sample labels of good communication and communication obstacle corresponding to the identification result of 1 or 2 respectively, thus, the vehicle-mounted terminal continuously collects the real-time voice conversation among the drivers and the passengers in the journey of the network appointment and inputs the real-time voice conversation into the driver and passenger dispute recognition model, and the driver and passenger dispute recognition model carries out model training calculation based on the real-time dialogue voice and outputs a recognition result.

In the embodiment, the real-time conversation voice between a driver and a passenger (hereinafter referred to as a driver and a passenger) is continuously collected in the whole journey of the online appointment vehicle by a client which is equipped on the online appointment vehicle and realizes the intelligent vehicle networking function; after acquiring real-time conversation voice among drivers and conductors, a client immediately takes the real-time conversation voice as model input and inputs the model input into a trained driver and conductor dispute recognition model, so that the driver and conductor dispute recognition model trains aiming at the model input to recognize the real-time conversation voice and output a recognition result capable of identifying whether dispute behaviors exist among the drivers and conductors; the client inputs the acquired real-time conversation voice into the driver and passenger dispute recognition model, so that after the driver and passenger dispute recognition model recognizes the real-time conversation voice and outputs a recognition result, if the client detects that dispute behaviors exist among drivers and passengers identified by the recognition result, the client immediately inputs a preset dispute stop prompt to timely stop the dispute behaviors.

Compared with the application of the intelligent car networking in the existing network car booking market, the intelligent car networking system can recognize whether dispute behaviors exist among drivers and passengers through real-time dialogue voice among the drivers and passengers, and output prompts to timely stop the dispute behaviors under the condition that dispute exists, does not need to rely on complicated video monitoring and other technologies, reduces the requirements on terminal calculation capacity and communication bandwidth, and ensures the effective development of the intelligent car networking in the network car booking market.

Further, based on the first embodiment of the method for suppressing network car-booking and driver-passenger dispute according to the present invention, a second embodiment of the method for suppressing network car-booking and driver-passenger dispute according to the present invention is provided, and in this embodiment, the method for suppressing network car-booking and driver-passenger dispute according to the present invention may further include:

and step A, carrying out federal learning training according to the network appointment vehicle and driver conversation samples to obtain a driver and driver dispute recognition model.

Before the client specifically applies the driver-car dispute recognition model to recognize real-time conversation voice among the network appointment car drivers and passengers, a machine learning federation is constructed together with other clients, so that the built network appointment car driver-car dialogue samples collected in advance are utilized to carry out federal learning training based on the machine learning federation, and the driver-car dispute recognition model capable of accurately recognizing whether disputes exist among the network appointment car drivers and passengers is obtained.

It should be noted that, in this embodiment, the network appointment car driving and taking conversation sample may be specifically constructed based on the collected conversation voice between the drivers and the passengers in each journey of the network appointment car, and when constructing the corresponding network appointment car driving and taking conversation sample based on each conversation voice, the tags of "good communication", "communication obstacle exists", or "dispute exists" are further added based on the actual situation of the conversation voice of the drivers and the passengers or the background staff. Specifically, for example, after the dialogue voice of the driver and the passenger in one trip of the networked car appointment is collected, a prompt for selecting the dialogue voice tag in the current completed trip is output to the driver of the networked car appointment, so that the driver can select 'good communication' as the dialogue voice tag according to the actual situation that no communication problem occurs between the driver and the passenger in the current trip; or, if a communication obstacle or a dispute occurs between the driver and the passenger in the current trip, the driver correspondingly selects "communication obstacle exists" or "dispute exists" as the label of the conversation voice.

Further, in a possible embodiment, each of the clients is connected to the server to form a learning federation, please refer to the flow illustrated in fig. 3, where the step a may include:

step A01, encrypting and uploading a network car booking user identifier to the server, so that the server performs sample alignment on the network car booking driving and taking conversation samples according to each encrypted network car booking user identifier;

it should be noted that, in this embodiment, the current client and other clients each bound or associated with a corresponding network appointment form a machine learning federation together with a server respectively connected to and trusted by each client. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, each client and even each server may be of the same type or different types of terminal devices, and the method for preventing vehicle-booking and driver-riding disputes according to the present invention is not limited to the specific types of the client and the server. In addition, in this embodiment, the online car booking user identifier may specifically be information such as a license plate number, a frame number, and/or a mobile phone number of a driver of the online car booking.

The client side encrypts the corresponding bound or associated network appointment vehicle user identification locally, and uploads the encrypted network appointment vehicle user identification to a server in a machine learning federation, so that the server can perform sample alignment operation on the constructed network appointment vehicle driving and taking conversation sample based on the network appointment vehicle user identification after receiving each encrypted network appointment vehicle user identification.

Further, in a possible embodiment, the step a01 may further include:

step A011, encrypting a local network car booking user identifier by using a secret key issued by the server to obtain an encrypted network car booking user identifier;

it should be noted that, in this embodiment, after each client and the server form the machine learning federation, the server distributes the key in the key pair to be generated to each client, so that each client performs encrypted data transmission with the server in the following. It should be understood that, based on different design requirements of practical applications, in different possible embodiments, the server may generate the key pair by using any mature key generation manner, and the method for preventing vehicle-department and driver-department disputes in the network is not limited by the process of generating the key pair by the server and the specific type of the key pair.

The client-side locally binds or associates the network car-booking user identification with the client-side, and the encrypted network car-booking user identification is obtained by encrypting the network car-booking user identification through a secret key issued by the server in advance.

And step A012, uploading the encrypted network car booking user identification to the server so that the server decrypts each network car booking user identification, determines the same network car booking user identification in each decrypted network car booking user identification, and performs global sample alignment on the network car booking driver and passenger conversation sample according to the same network car booking user identification.

The client side encrypts the bound or associated network car-booking user identifications by using the secret key issued by the server, and uploads the encrypted network car-booking user identifications to the server, so that the server decrypts the public key in the public key by using the pre-generated secret key after receiving the encrypted network car-booking user identifications, analyzes and contrasts whether the decrypted network car-booking user identifications are the same or not, thereby determining the same network car-booking user identification, and then the server performs global sample alignment operation on the constructed network car-booking driving conversation sample according to the same network car-booking user identification.

It should be noted that, in this embodiment, the server may specifically determine the same network car booking user identifier according to whether each decrypted network car booking user identifier belongs to a category. Specifically, for example, whether each network car booking user identifier is the same license plate number, the same frame number, the same mobile phone number, or the like is determined, so that a plurality of network car booking user identifiers belonging to the same license plate number, frame number, or mobile phone number are determined to be the same network car booking user identifier.

Step A02, receiving training samples which are sent by the server and correspond to the network appointment user identifications after sample alignment, and performing local model training by using the training samples to generate model parameters;

the client uploads the encrypted network appointment user identification to the server, so that the server decrypts the network appointment user identification and aligns global samples for network appointment car driving and taking conversation samples according to the same network appointment user identification, the server determines the network appointment car driving and taking conversation samples corresponding to the same network appointment user identification as training samples corresponding to the network appointment car user identification, then the server further issues the training samples to the corresponding client according to the same network appointment user identification, the client receives the training samples, and local model training is performed locally for an initial machine learning model to obtain model parameters of the machine learning model.

Specifically, for example, the machine learning model local to each client may specifically be a mature speech recognition model such as DFCNN, LAS, and the like, and the model parameters may specifically be network appointment, driver and passenger conversation feature vectors and sample labels output by the model. Referring to the application flow shown in fig. 4, after the client 1, the client 2, and the client 3 upload the network appointment user identifier (illustrated user ID)1, the network appointment user identifier 2, and the network appointment user identifier 3 encrypted by the key to the server, and the server decrypts the encrypted network appointment user identifier 1, the network appointment user identifier 2, and the network appointment user identifier 3 based on the public key corresponding to the key, it is determined that the network appointment user identifier 1 and the network appointment user identifier 2 are the same network appointment user identifiers belonging to the same category through analysis, the server performs a global sample alignment operation on the pre-constructed network appointment car riding conversation sample by using the network appointment user identifier 1 or the network appointment user identifier 2 together with the network appointment user identifier 3, and then the server further determines that the portion of the network appointment car riding conversation sample corresponding to the network appointment user identifier 1 or the network appointment user identifier 2 is the training sample 1, and determining the part of online appointment car driving and taking conversation samples corresponding to the online appointment car user identification 3 as training samples 2, respectively issuing the training samples 1 to the client 1 and the client 2, and issuing the training samples 2 to the client 3. Accordingly, after receiving the training sample 1 and the training sample 2, the client 1, the client 2, and the client 3 each start local model training on the initial machine learning model (DFCNN, LAS, or the like) locally, and then the client 1 trains the initial machine learning model locally using the training sample 1 to generate the car-to-car-riding conversation feature vector (illustrated car-to-car voice communication feature vector) 1 and the sample label 1, the client 2 trains the initial machine learning model locally using the training sample 1 to generate the car-to-car-riding conversation feature vector 2 and the sample label 2, and the client 3 trains the initial machine learning model locally using the training sample 2 to generate the car-to-car-riding conversation feature vector 3 and the sample label 3.

Step A03, uploading the model parameters to the server, so that the server updates the local department dispute recognition model to be confirmed at each client according to each model parameter until the department dispute recognition model converges or reaches a preset iteration training round.

The client-side carries out model training by using a corresponding training sample locally to obtain model parameters, then the model parameters are further uploaded to the server, so that the server carries out loss value calculation and feedback according to the model parameters, and updates the to-be-confirmed driver and conductor dispute recognition model which is trained locally by each client-side.

It should be noted that, in this embodiment, the preset iterative training round may be specifically generated by the client or the server based on the configuration of the staff, and is used to identify the number of times of model iterative training that has been completed by the client in the cyclic training update process for the department dispute recognition model in the current machine learning federation.

Further, in a possible embodiment, the model parameters are uploaded by the client after being encrypted by using a key, and step a03 may include:

step A031, upload to the said server after utilizing the cipher key to encrypt the said model parameter;

after the client performs model training locally by using the corresponding training sample to obtain the model parameters, the client further encrypts the model parameters by using a secret key issued by the server in advance, and uploads the encrypted model parameters to the server for loss value calculation.

Step A032, receiving the loss value fed back by the server, wherein the server decrypts the model parameter to obtain a decrypted network car-sharing and car-sharing conversation feature vector, and calls a preset loss function to calculate the network car-sharing and car-sharing conversation feature vector to obtain the loss value;

it should be noted that, in this embodiment, the preset loss value function may be any mature loss function, and based on different design requirements of practical applications, in different feasible implementation manners, the server may use different loss functions, so that the method for suppressing vehicle-sharing and driver-riding disputes in the present invention is not limited by the specific type of the preset loss value function.

After the client encrypts and uploads the model parameters obtained by local model training to the server, the server decrypts the encrypted model parameters through a local public key, then calls a preset loss value function to calculate a loss value, and feeds the loss value back to each client for model updating operation.

Specifically, for example, referring to the application flow shown in fig. 4, after the client 1 trains the initial machine learning model locally with the training sample 1 to generate the car-riding conversation feature vector 1 and the sample label 1, the client 2 trains the initial machine learning model locally with the training sample 1 to generate the car-riding conversation feature vector 2 and the sample label 2, and the client 3 trains the initial machine learning model locally with the training sample 2 to generate the car-riding conversation feature vector 3 and the sample label 3, the client 1, the client 2, and the client 3 encrypt and upload the car-riding conversation feature vector 1, the car-riding conversation feature vector 2, and the car-riding conversation feature vector 3 respectively with the key issued in advance by the server, and the server receives the encrypted car-riding conversation feature vector 1, the encrypted car-riding conversation feature vector 2, and the encrypted car-riding conversation feature vector 3, and receives the encrypted car-riding conversation feature vector 1, The network car-sharing and car-sharing conversation feature vector 2 and the network car-sharing and car-sharing conversation feature vector 3 are obtained through decryption by using a public key corresponding to the secret key, the network car-sharing and car-sharing conversation feature vector 1, the network car-sharing and car-sharing conversation feature vector 2 and the network car-sharing and car-sharing conversation feature vector 3 are obtained, then the server calls a loss function which is configured locally by a worker in advance, and loss values (graphic loss function values) are obtained through calculation based on the network car-sharing and car-sharing conversation feature vector 1, the network car-sharing and car-sharing conversation feature vector 2 and the network car-sharing and car-sharing conversation feature vector 3, and the loss values are encrypted and then fed back to the client 1, the client 2 and the client 3 respectively.

Step A033, calculating a gradient value locally according to the loss value, and updating a local to-be-confirmed driver-crew dispute identification model by using the gradient value.

After receiving the loss value fed back by the server, the client-side respectively calculates gradient values locally based on the loss value, so that the local to-be-confirmed driver and passenger dispute model is updated by the gradient values.

It should be noted that, in this embodiment, the client may specifically adopt any mature model gradient value calculation mode to calculate the gradient value based on the loss value issued by the server, and update the machine learning model that has been trained by the local model according to the gradient value. It should be understood that, based on different design requirements of practical applications, the calculation processes of calculating the gradient value by each client locally based on the loss value issued by the server may be different, and the method for preventing network appointment of vehicle and driver disputes of the present invention is not limited to the specific process of calculating the gradient by the client based on the loss value.

Further, in this embodiment, after the client locally updates the to-be-confirmed dispute recognition model (that is, the client locally uses the machine learning model that is model-trained by the training sample) based on the calculated gradient value, if the dispute recognition model is converged, or the number of times that the client currently uses the gradient value to update the dispute recognition model reaches the preset iteration training round, the client determines that the dispute recognition model is trained, so that the client can use the dispute recognition model to recognize the real-time dialogue speech between the network appointment car drivers and obtain an accurate recognition result of whether disputes exist between the drivers and the passengers.

In this embodiment, before the client specifically applies the department dispute recognition model to recognize the real-time conversation voice between the network appointment car drivers and passengers, a machine learning federation is first constructed together with other clients, so that the machine learning federation is used for carrying out federal learning training by using pre-collected constructed network appointment car driver and passenger conversation samples, and the department dispute recognition model capable of accurately recognizing whether disputes exist between the network appointment car drivers and passengers is obtained.

Therefore, when the method is used for preventing potential disputes among the network car and the drivers and the passengers, the real-time conversation voice between the network car and the drivers and the passengers collected by the client can be directly input into the driver and passenger dispute recognition model, so that the driver and passenger dispute recognition model can recognize the real-time conversation voice and output an accurate recognition result, and finally, the client can output a preset dispute prevention prompt when discovering that the recognition result identifies dispute behaviors among the drivers and passengers of the network car, thereby preventing the dispute behaviors in time.

Compared with the application of the intelligent car networking in the existing network car booking market, the intelligent car networking system and the method have the advantages that the dispute behavior of the drivers and the passengers is accurately identified by training the driver and passenger dispute identification model, so that the technology of complicated video monitoring and the like is not required, the requirements on terminal calculation capacity and communication bandwidth are reduced, and the effective development of the intelligent car networking in the network car booking market is ensured.
