Description

A system for restricting driving privileges based on traffic history

technical field

The present invention relates to a system for restricting driving rights based on traffic history, especially for shared cars.

Background technique

The sharing economy generally refers to a new economic model based on strangers and the temporary transfer of the right to use items for the main purpose of obtaining certain rewards. Its essence is to integrate offline idle items, labor, education and medical resources. Some also say that the sharing economy is that people enjoy social resources fairly, pay and benefit in different ways, and jointly obtain economic dividends. This kind of sharing is more realized through the Internet as a medium.

The current car sharing is a model of the sharing economy. Car sharing means that many people share a car, that is, the driver only has the right to use the car, but not ownership. Car sharing generally uses a company to coordinate vehicles and is responsible for issues such as vehicle insurance and parking. A shared car is not an individual's private property, but belongs to a certain group or enterprise. It can be parked at will so that non-specific users can take it at any time, such as using the vehicle by swiping a card or swiping a QR code. This method can not only save money, but also help to alleviate traffic congestion, wear and tear on roads, reduce air pollution, and reduce dependence on energy. The development prospects are extremely broad. However, shared cars cannot clearly define the driving authority of users, so that users who do not have driving qualifications drive cars, and there are potential safety hazards in the process of driving.

Chinese patent (CN 104395937) discloses an access authority or driving authority system for vehicles, including: a mobile communication device, and vehicle manufacturer authority data used to authorize the vehicle access authority or driving authority system, wherein the mobile communication The device has a data carrier for storing the communication identification information of the mobile communication device and the authority data of the vehicle, and the authority data is sent to the access authority or driving authority system of the vehicle by means of a communication connection through the mobile communication device, wherein the authority data can Stored in the storage area of the data carrier, the storage area can be written and read by the vehicle manufacturer through authorization, the communication connection between the mobile communication device and the access authority or driving authority system is wireless near-field communication, and the authority data Can be transferred from the database server authorized by the vehicle manufacturer to the mobile communication device. However, the driving authority system cannot identify the driving identity of the driving user, let alone limit the driving authority of the driving user according to the traffic history records of the driving user. For example, for a driving user who always drives over the speed limit and has been punished many times for speeding, the driving authority system cannot reject the driving user. For drivers who do not have driving qualifications, the driving authority system cannot restrict or prohibit drivers from using shared cars. For a driver who has an unexpected physiological situation during driving, the driving authority system cannot intervene in vehicle control to protect the driver's personal safety and avoid driving risks.

Therefore, there is an urgent need in the market for a system that can identify and limit the driving authority of drivers based on traffic history records, so as to solve how to limit the driving of people with high driving risks to avoid safety risks and guarantee Technical issues of personal safety.

Example 1

A shared car that restricts driving privileges based on user history. As shown in FIG. 1 , a shared car includes at least a first authentication module 10 and an authority restriction module 50 . The first authentication module 10 is responsible for generating the first risk assessment parameters for non-specific users as users when using the shared car in a time-sharing manner, and the authority restriction module 50 decides whether to provide the user with Provide access to the shared car. The first authentication module 10 identifies the legal identity and basic driving qualification of the user based on the identity information sent by the user through the mobile terminal.

Preferably, the first authentication module 10 confirms the user's ID number, name, age, gender, address, driver's model, driver's license number and validity period of the driver's license based on the personal identity information. The first authentication module 10 basically checks and checks the identity information and the ID card number. After checking the user's identity information, the first authentication module 10 sends the user's personal identity information to the second authentication module.

The shared car also includes a second authentication module 20 which is set independently from the first authentication module 10 and can be remotely connected to the history record database through the communication interface of the shared car. The second authentication module 20 retrieves historical data matching the user's identity information from the history record database based on the user's identity information. Historical data is data related to the user, such as the user's traffic history and credit index.

Preferably, the second authentication module 20 sends a query request to at least one historical record database remotely provided by an independent third party based on the user identity information obtained by the first authentication module of the user, using To obtain past historical data related to the user as a second risk assessment parameter for using the shared car.

Preferably, the second authentication module 20 sends the ID number of the user to the traffic record database, and queries the matching driver's license information and traffic history record information. The second authentication module 20 matches the driver's license information obtained from the query with the ID card basic information sent by the first authentication module. If the audit finds that the user does not have a driving certificate record, or the driving certificate information queried based on the identity information does not match the user's identity information, the second authentication module 20 sends information that does not have driving qualifications to the authority restriction module 50 . The authority restriction module 50 does not send an instruction to unlock the car lock to the shared car, and the doors and windows of the shared car are closed and will not be opened. Wherein, the authority restriction module 50 unlocks the car lock control unit of the shared car based on the legal identity information of the user.

The second authentication module 20 retrieves the traffic history record of the user when the driver's license information matches the basic information of the ID card successfully. The second authentication module 20 selects the traffic violation record in the traffic history record as the second risk assessment parameter. Preferably, the authority restriction module 50 evaluates the driving risk level of the user based on the second risk assessment parameter and the user identity information, and determines that the user is using the shared car based on the driving risk level period of driving authority.

For example, the user's violation records include 2 times of speeding within 20%, 1 time of speeding 20%-50%, 1 time of violating traffic signal instructions and 1 time of not wearing a seat belt. The risk parameter for speeding 20% is 3, the risk parameter for speeding 20%-50% is 6, the risk parameter for violating traffic signal instructions is 2, and the risk parameter for not wearing a seat belt is 2.

The second authentication module 20 sends the second risk assessment parameters together with the user identity information from the first authentication module 10 to the authority restriction module 50 integrated in the shared car. The authority restriction module 50 evaluates the driving risk level of the user based on the second risk evaluation parameter and the user identity information. Then the user's risk parameter is: A=3*2+6*1+2*1+2*1=16. The algorithm of the risk parameter in the present invention is not limited thereto, and may also include other complex calculation methods.

Driving risk levels are classified according to the range of risk parameters, including Level 1, Level 2, Level 3 and Level 4. For example, the risk parameter range of the first-level driving risk is 0-5, the risk parameter range of the second-level driving risk is 6-10, the risk parameter range of the third-level driving risk is 11-15, and the risk parameter range of the fourth-level driving risk is 16-20. Then the user has level 4 driving risk.

The authority restriction module 50 determines the user's driving authority range according to the speeding violation driving behavior and frequency of the user. Wherein, since the user has a traffic history record of speeding and the frequency is 3 times, the user's maximum driving speed is limited. For example, the user's maximum driving speed is limited to 60km/h. For acceleration commands greater than 60km/h issued by the user, the acceleration control unit of the shared car does not execute.

Preferably, the authority restriction module 50 determines the speed limit of the road based on the geographic location information, and uses the speed limit value of the road as the restricted driving speed of the user.

Preferably, the second authentication module 20 is set in an independent monitoring terminal 60 . The monitoring terminal 60 is fixed to the shared car in a manner that is electrically wired for power supply and data communication, and is mechanically detachable but cannot be lost. The connection mode between the monitoring terminal 60 and the shared car is that the monitoring terminal 60 establishes a data connection with the CAN bus via the OBD interface of the shared car 80 . The monitoring terminal 60 can acquire or provide data and commands from the second authentication module 20 .

After the first authentication module 10 identifies and verifies the user's identity and basic driving qualifications, the authority restriction module 50 controls the opening of the car door of the shared car, allowing the user to enter the cabin of the shared car. After the user enters the driver's seat, the power supply of the shared car is switched on, the power supply of the monitoring terminal 60 is also switched on, and the monitoring terminal 60 starts.

Preferably, the monitoring terminal 60 is a smart device with a display screen. The monitoring terminal 60 includes a computer, a laptop, a tablet, a smart phone and/or smart glasses. The monitoring terminal 60 is connected with non-specific shared cars in a wired manner to prevent the monitoring terminal 60 from being stolen or lost by criminals. Moreover, the wire connecting the monitoring terminal 60 and the shared car may be a data wire with an elastic structure or made of elastic material capable of transmitting current and data. While preventing the monitoring terminal 60 from being separated from the shared car 80, the data line can ensure the power supply of the monitoring terminal 60 and data interaction with the shared car, so that the monitoring terminal 40 can monitor the operation of the shared car.

By interacting with the second authentication module 20 integrated in the monitoring terminal 60, the authority restriction module 50 can determine the The range of driving authority of the user at each time period during the use of the shared car 80 .

For example, the monitoring terminal 60 collects the driving actions and voices of the users in the shared car. When the user holds the steering wheel with one hand and answers the phone with the other hand, the monitoring terminal 60 collects images of the user answering the phone and sends them to the authority restriction module 50 . The authority restriction module 50 determines from the image sent by the monitoring terminal 60 that the driving risk of the user answering the phone has increased, and the user's maximum driving speed limit is changed from 80km/h to 60km/h. The authority restriction module 50 judges that the user resumes the driving behavior of holding the steering wheel with both hands according to the image sent by the monitoring terminal 60, and restores the user's maximum driving speed limit from 60km/h to 80km/h.

Preferably, the monitoring terminal 60 is provided with a third authentication module 30 . During the waiting period when the second authentication module 20 inquires historical information from the historical record database 70 provided by a third party, the third authentication module 30 according to the user identity information obtained by the first authentication module 10 Setting natural language and testing the current state of the user as a third risk assessment parameter.

Preferably, the third authentication module 30 uses the natural language to test the current status of the user in a voice and/or video interactive manner.

For example, the third authentication module 30 displays several psychological test questions and/or polygraph questions on the touch screen. Psychological test questions and/or polygraph questions can be displayed on the touch screen in the form of question and answer, dictation and/or games to interact with the user. The third authentication module 30 evaluates the user's psychological state parameter and integrity parameter based on the user's feedback answer. The third authentication module 30 sends a message of refusal to drive on the touch screen in the form of voice and/or text information for users whose integrity parameters are lower than the integrity threshold and/or users whose psychological state parameters are in the abnormal threshold range, and simultaneously The driving information is sent to the authority restriction module 50 . Furthermore, the third authentication module 30 sends an instruction to the second authentication module 20 to stop querying the historical data.

Preferably, the authority restriction module 50 divides authority control levels based on the user's psychological state parameters. The authority control levels include at least A-level authority with full authority, B-level authority with limited partial authority based on psychological defects and traffic history information, and C-level authority with high-risk driving risks.

Preferably, the authority restriction module 50 limits the user's driving route range based on the user's traffic history records, and changes the user's authority control level based on the user's behavior feedback on warning information.

For example, the Sichuan-Tibet Expressway has high risks for ordinary users. Therefore, the authority restriction module 50 hides the route map of the Sichuan-Tibet Expressway when the navigation device of the shared car displays the electronic map. For example, if the driving range of the shared car is regional, the authority restriction module 50 will send a warning message to the user when the shared car drives out of the limited province or city. When the user does not accept the warning message and continues to drive out of the restricted area, cancel the user's driving authority, control the shared car to park in the safe area of the attachment based on the auxiliary control command, and send a help message to the shared car platform, waiting for the arrival of support personnel.

Preferably, a fourth authentication module 40 is installed in the monitoring terminal. The fourth authentication module 40 can actively collect the data of the control unit related to driving and/or manipulation of the shared car 80 after establishing a data connection with the control unit of the CAN bus through the monitoring terminal 60 and the OBD interface.

Wherein, the user operates the corresponding control unit of the shared car according to the operation request in video form provided by the monitoring terminal 60 including at least a touch screen and a gravity sensor. During operation, the user generates data of the drive- and/or steering-related control unit that can be acquired by the fourth authentication module 40 , thereby forming a fourth risk assessment parameter. The fourth authentication module 40 sends the fourth risk assessment parameter to the authority restriction module.

Preferably, the monitoring terminal 60 establishes a data connection with the CAN bus and OBD interface of the shared car, so as to be able to obtain relevant data, instructions and operating status of each control unit of the shared car.

Preferably, the monitoring terminal 60 is provided with a simulation program for simulating the traffic driving environment. The monitoring terminal starts and guides the user to perform a simulated driving test based on the unlocking information of the car lock control unit of the shared car by means of voice, sound and/or vibration. The user performs normal driving operations in the shared car according to the simulated driving environment. The monitoring terminal 60 reads the data of each control unit of the shared car operated by the user in the simulated environment, thereby obtaining the user's reaction time and driving operation data, thereby evaluating the user's driving ability. If the user's driving ability is poor and the response is slow, the user is refused to drive the shared car. If the user's driving ability and reaction time meet the driving standards, the authority restriction module 50 grants the user the driving authority.

Preferably, the monitoring terminal 60 is activated based on the unlocking information of the lock control unit of the shared car 80 by voice, sound and/or vibration and guides the user to perform a simulated driving test.

Preferably, the authority restriction module 50 is further configured to use the first, second, third and/or fourth risk assessment parameters according to the driving style of the corresponding user during the use of the shared car. The mode is displayed to the user on the touch screen of the monitoring terminal 60 . That is, the user can know all his risk assessment parameters through the touch screen of the monitoring terminal 60 when the driving ends. During the settlement period after the user completes the use of the corresponding shared car, the authority restriction module 50 sends the preferential rate parameter to the settlement system based on the corresponding risk assessment parameters and the driving style of the user during this period, and at the same time, the preferential parameter is represented by digital The method is displayed to the user on the touch screen of the monitoring terminal. Users get discounts through good driving habits, which will encourage users to maintain driving habits next time. By feeding back the risk assessment parameters of not accepting warnings and high driving risks, the user will pay attention to standard driving operations in future driving operations in order to get more discounts.

For example, if a user violates traffic rules by not wearing a seat belt or speeding, in addition to deducting traffic fines, the preferential rate enjoyed by the user is reduced from 50% to 20%. Users will know their violations through the discount rate calculation, and regulate their driving behavior in order to increase the discount rate in the future driving process.

Preferably, the authority restriction module 50 stores the preferential rate parameter in the database of the control center of the shared car via the remote communication unit of the shared car as one of the user's basic scores. Users with good driving habits, the longer the number and time of renting a car, the more discounts they can enjoy and the greater their driving authority. Users with illegal driving habits will also regulate driving in order to expand their driving authority.

Example 2

This embodiment is a further improvement on Embodiment 1, and repeated content will not be repeated.

Preferably, the monitoring terminal 60 includes an analog module 31 and a control module 32 .

The simulation module 31 establishes a connection with the brake control unit and the acceleration control unit of the shared car based on the power supply of the shared car, and sends protection instructions to the control module 32 to protect the ignition control unit and the parking control unit. The control module 32 controls the ignition control unit and/or the parking control unit of the shared car to enter the protection state without accepting the maneuvering command of the shared car based on the protection command of the simulation module 31 .

The simulation module 31 instructs the user to drive the shared car by simulating the driving environment. The simulation module 31 plays road traffic conditions on the display screen, and the user performs driving operation according to the simulated road traffic conditions. At this time, the shared car will not move because the ignition control unit and/or the parking control unit are in a protected state.

For example, the simulation module 31 first plays normal road conditions, and the user performs an acceleration or deceleration operation according to the simulated traffic road on the display screen of the monitoring terminal 60 . Data, instructions and/or state changes related to the brake control unit and the acceleration control unit are actively or passively detected by the analog module through the CAN bus and the OBD interface. The simulation module 31 evaluates at least one test parameter of the stress behavior of the user during simulated driving based on the data, instructions and/or state changes related to the braking control unit and the acceleration control unit, and according to at least one of the test parameters The driving ability index is comprehensively calculated.

Preferably, the simulation module 31 evaluates the test parameters of the stress behavior based on data, instructions and/or state changes related to the braking control unit and the acceleration control unit.

For example, if there is a wrong-way vehicle in front of the simulated traffic road, the user can avoid the wrong-way vehicle by stepping on the brakes and steering. The simulation module 31 counts the reaction time of the user and the correctness of the steering according to the time when the retrograde vehicle appears and the time when the user's operation behavior occurs. Reaction time corresponds to a test parameter value indicating the degree of response, and correctness corresponds to a test parameter value.

Preferably, the simulation module 31 tests at least one test parameter corresponding to at least one stress behavior of the user based on a simulated driving environment, and comprehensively calculates the driving ability index based on the test parameters.

The simulation module 31 evaluates the user's driving ability index based on the stress driving behavior of the user during simulated driving, and the authority restriction module 50 determines that the user is using the shared car based on the driving ability index period of driving authority.

For example, the simulation module 31 records and detects the driving operation behaviors of multiple users and the corresponding test parameters. The simulation module 31 evaluates the reaction speed of the user and the accuracy of the driving behavior according to a plurality of driving behavior test parameters. The faster the reaction speed and the higher the correct rate of driving operation, the higher the user's driving ability index. The user makes 3 driving actions, the reaction time of the first driving action is 1S, which is correct; the reaction time of the second driving action is 2S, which is correct; the reaction time of the third driving action is 0.5S, which is wrong; then the user The response index is (1+2)/2=1.5, and the correct rate is 2/3. The proportion of response ability is 0.5, and the proportion of correct rate is 0.5. Then the driving ability index of the user is: 1.5*0.5+2/3*1/2=0.75+0.33=1.08.

The simulation module 31 sends the user's driving ability index and information on granting driving authority to the authority limiting module 50 . The threshold for driving ability is 0.5.

When the matching parameters of the user's physiological state parameters and the operating data are lower than a matching threshold, the user's driving authority is canceled, and the shared car is controlled to drive to a designated parking location based on geographic location information.

For example, the monitoring terminal 60 monitors the physiological state of the user. When the physiological parameters of the user or the operating parameters of the shared car are abnormal, the control module 32 actively controls the shared car and slowly moves to a safe area to stop. For example, if the user's eyes are closed and the shared car is still running while the user's eyes are closed, the user's physiological state does not match the operating data of the shared car. The monitoring module 33 instructs the control module 32 to control the shared car according to the driving environment. safe area.

Preferably, the judgment module judges the operation safety index of the shared car based on the operation data of the shared car, and sends an auxiliary control instruction to the control module when the operation safety index is less than a threshold value of the operation safety index The shared car is controlled to be parked in a safe area.

The judgment module judges the fault of the shared car and the corresponding operation safety index based on the data of the OBD interface. If the operation safety index is greater than the threshold value of the operation safety index, and the driving of the shared car is relatively safe, the judging module will send fault information to the remote support center after the user's driving trip is over, waiting for technical support. If the operation safety index is less than the operation safety threshold, the operation failure of the shared car endangers the user's personal safety, and the judging module sends an auxiliary control command to the control module 32 . The control module 32 controls the braking control unit and the parking control unit of the shared car, so that the shared car slowly parks to a safe area. Moreover, the judging module sends a prompt to the user that the vehicle is faulty, and asks the user to wait for a replacement vehicle, so as to reduce the driving risk of the user.

Preferably, the physiological monitoring module sends emergency rescue information and auxiliary control information to the control module 32 based on abnormal physiological parameters. The control module 32 responds to the emergency rescue information and the auxiliary control information, sends a distress message to the emergency rescue center and controls the shared car to stop at the identified rescue geographic location.

For example, a user has a heart attack while driving. The physiological monitoring module judges that the user's physiology is abnormal based on the user's action of leaving the steering wheel, head movement and/or facial expression during driving. The physiological monitoring module sends emergency rescue information and auxiliary control information to the control module 32 to ensure the safe driving of the shared car, thereby protecting the personal safety of users. The control module 32 actively controls the operation of the shared car, and feeds back the pre-stopped parking location to the emergency rescue center. The control module 32 drives the shared car to a safe location, waiting for rescuers. Preferably, the safe location may also be the rescue geographic location sent by the emergency rescue center.

For example, based on the data information detected by the CAN bus, the judging module determines that the brakes of the shared car are faulty, and the corresponding emergency index is 8, which is relatively high. The judging module sends an emergency parking instruction and/or a safe parking instruction to the control module 32 based on the failure urgency index. The control module 32 executes the emergency parking command and/or the safe parking command, and sends emergency failure information to a remote support center through the communication module of the monitoring terminal 60 . The remote support center instructs at least one support site close to the shared car to provide standby vehicles or technical support at the shared car stop. The system of the present invention can guarantee the personal safety of the user according to the failure of the vehicle, prevent traffic accidents caused by the failure of the vehicle, and prevent the user from delaying the scheduled events due to the failure of the vehicle.

Preferably, the monitoring module further includes an environment monitoring module.

The environment monitoring module monitors the driving environment parameters outside the shared car based on at least one sensor and analyzes the driving environment in real time. The judging module judges sudden dangerous situations based on abnormal parameters of the driving environment and sends corresponding auxiliary control information to the control module when the user does not make relevant driving operations within the emergency time threshold. The control module 32 responds to the auxiliary control information and sends corresponding control commands according to the abnormal parameters of the driving environment, so as to jointly control the steering control unit 84, ignition control unit 81, brake control unit 82, acceleration The control unit 83 and/or the parking control unit 85 are used to drive the shared car to avoid sudden dangerous situations.

Preferably, the environment monitoring module includes at least one sensor and at least one radar to monitor the external environment and driving environment of the shared car. For example, the judging module judges that a dangerous vehicle is suddenly approaching the shared car at a very fast speed according to the data sent by the rear sensor of the shared car. When the dangerous vehicle approaches the safe area of the shared car within 5 seconds, and the driving monitoring module does not monitor the relevant driving operation of the user, the judging module sends corresponding auxiliary control information to the control module 32 . The control module 32 sends corresponding control commands according to the abnormal parameters of the driving environment, controls the ignition control unit 81 to ignite, and controls the acceleration control unit to accelerate, so that the shared car accelerates to avoid dangerous vehicles.

Preferably, the monitoring terminal is also provided with an alcohol testing device 90 .
