Detailed ways

Various exemplary embodiments, features, and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In addition, in order to better illustrate the present invention, numerous specific details are given in the following specific embodiments. It will be understood by those skilled in the art that the present invention may be practiced without certain specific details. In some instances, means that are well known to those skilled in the art are not described in detail in order to highlight the gist of the invention.

One embodiment of the present invention proposes a vehicle toll payment method. The method is implemented based on an execution subject of a vehicle-mounted assistant to execute the steps of the method. The vehicle-mounted assistant can be understood as an intelligent terminal, and specifically can be a vehicle-mounted voice assistant. The assistant can have voice interaction function, conduct voice interaction with the driver, and automatically pay the toll according to the driver's voice instructions; it can also communicate and transmit data with other control units or sensing units of the vehicle, and the toll management platform of any toll road section. interaction, and the ability to access and search any online high-definition map data via the Internet. Among them, the car owner assistant binds the car owner's payment account, such as the credit card account number and payment password, to achieve automatic payment.

Referring to Figure 1, the method of this embodiment at least includes the following steps S1 to S4:

Step S1. When the vehicle enters the entrance of a certain toll road section, the vehicle-mounted assistant interacts with the toll management platform at the entrance of a certain toll road section to obtain charging standard information, and starts to calculate the toll based on the certain charging standard information to obtain real-time of the first toll bill.

Specifically, each toll section will be equipped with a toll management platform, such as the popular ETC in China, which is an all-weather unattended smart toll management system with an Internet server to control the operation and a full set of vehicle traffic detection and confirmation. , process billing, bill generation, issuing charging applications, charging, releasing and other series of functions. Generally speaking, the status of vehicles entering the monitoring range of a toll road section includes four states: waiting to enter, having entered, waiting to exit, and having exited; the waiting to enter means that the vehicle is waiting to enter the toll section at a certain entrance. Having entered means that the vehicle has entered the toll road section from a certain entrance, the waiting to exit means that the vehicle is waiting to exit the toll road section at a certain exit, and the said having exited means that the vehicle has exited the toll road section from a certain exit.

Generally speaking, the toll standards for different toll road sections may be different, for example: small cars with trucks below 2 tons (including 2 tons), passenger cars with 20 seats or less, 0.45 yuan/km; medium-sized cars with 2 tons or more to 7 tons (Including 7 tons) trucks, passenger cars with more than 21 to 50 seats, 0.90 yuan/km; large vehicles with more than 7 tons to 20 tons (including 20 tons) trucks, passenger cars with more than 51 seats, sleeper buses, 1.462 yuan/km; extra large vehicles Trucks and container trucks over 20 tons are 2.138 yuan/km; therefore, in this embodiment, the on-board assistant calculates the communication fee based on the actual toll standard of the toll section and the number of kilometers traveled by the vehicle to obtain the real-time first toll bill; for example , before the vehicle enters the entrance E1 of the toll section #L1, the on-board assistant will establish a communication connection with the toll management platform S1 of the toll section #L1 in advance, and the on-board assistant can obtain the toll section by interacting with the toll management platform S1 of the toll section #L1 Charging standard information of #L1; the vehicle kilometers traveled can be determined based on the distance between the entrance E1 location and the vehicle's real-time location.

Step S2: When the vehicle enters any exit branch line of a certain toll road section and the navigation distance between the vehicle and the exit branch line is ≤ the first preset distance threshold, the vehicle assistant outputs a message to prompt the driver whether to make automatic payment. First prompt information.

It should be noted that this embodiment makes the judgment based on the navigation distance, which is the actual distance traveled by the vehicle from the current location to the destination, which is different from the straight-line distance; the first preset distance threshold is, for example, 200 meters. Specific adjustments can be made within the application.

Among them, any toll road section will have multiple exit branches, and each exit branch leads to an exit. It can be understood that when a vehicle enters any exit branch of a certain toll road section, it means that the vehicle is preparing to exit the toll road section. , at this time, if the navigation distance between the vehicle and the exit of the exit branch line ≤ the first preset distance threshold, it means that it is relatively close to the exit, and the on-board assistant will output the first prompt information. The output method of the first prompt information is preferably a voice broadcast. method, the content of the first prompt information may include the specific situation of the real-time first toll bill and whether the in-vehicle assistant is allowed to make automatic payment, for example, "You have driven X kilometers on the toll section #L1, and the toll fee It is Y yuan, please confirm whether to make automatic payment." The first prompt message can be generated based on the preset corpus, and can also be set independently according to the car owner's personal habits.

Step S3: When the on-board assistant receives the first voice command from the driver, it determines to enter the automatic payment mode or the manual payment mode according to the first voice command; wherein, if the automatic payment mode is entered, the on-board assistant and toll management The platform interacts to obtain the second toll bill calculated by the toll management platform, and compares the first toll bill with the second toll bill;

Specifically, after outputting the first prompt information, if the on-board assistant receives the first voice command issued by the driver, the on-board assistant recognizes the first voice command and determines what the driver wants to do based on the recognition result. Whether to make automatic payment or manual payment; manual payment means that the driver pays offline by himself, and the in-car assistant does not participate in the payment process; automatic payment means that the in-car assistant makes online payment;

Further, if automatic payment is performed, the on-board assistant communicates and interacts with the toll management platform to obtain the second toll bill calculated by the toll management platform, and then compares the above two bills; as mentioned above, the toll fee The management platform will calculate the tolls for vehicles entering the toll section.

Step S4: When the first toll bill is consistent with the second toll bill, when the vehicle arrives at the exit of the toll section, the on-board assistant interacts with the toll management platform based on the second toll bill to complete the process. Pay.

Specifically, the first toll bill is consistent with the second toll bill, that is, the tolls calculated by the in-vehicle assistant and the toll management platform are the same, indicating that the toll collection is reasonable, and the vehicle reaches the toll section. When exiting, the vehicle-mounted assistant interacts with the toll management platform according to the second toll bill to complete the payment. After the payment is completed, the vehicle exits the toll section through, for example, exit E1.

During the implementation of the method of the embodiment of the present invention, vehicle toll payment can be automatically realized through the vehicle-mounted assistant, which greatly simplifies the driver's manual operation of vehicle toll payment, improves the convenience of vehicle toll payment and driving safety, and the vehicle-mounted assistant Toll billing can also be carried out. According to the charging results, the toll bill given by the toll management platform can be checked. Based on the verification results, it can be determined whether to make automatic payment. This can improve the safety of automatic payment of vehicle tolls, so that in Improve car owners’ smart driving experience while ensuring information and payment security.

In a specific example, the on-board assistant in step S4 interacts with the toll management platform according to the second toll bill to complete the payment, which specifically includes:

When the vehicle arrives at the exit of the toll road section, the vehicle-mounted assistant interacts with the toll management platform to obtain vehicle status information; if the vehicle status information is in the waiting state, the vehicle-mounted assistant performs the processing according to the second toll bill and the toll management platform. Interact to complete the payment, and output a second prompt message indicating that the toll payment is successful.

Specifically, as mentioned above, the vehicle status includes entered and waiting to exit. When the vehicle reaches the exit of the toll section, the toll management platform will recognize that the vehicle has arrived at the exit, and the toll management platform will correspondingly store the vehicle. The status of the vehicle is updated from entered to waiting to exit; at this time, the vehicle status information obtained by the vehicle assistant interacting with the toll management platform is waiting to exit. When it is determined that the vehicle status is waiting to exit, it means that you can pay the toll and drive. When exiting the corresponding exit, the vehicle-mounted assistant interacts with the toll management platform according to the second toll bill to complete the payment, and outputs a second prompt message indicating that the toll payment is successful. The output method of the second prompt message is preferably: In the voice broadcast mode, the content of the second prompt message is, for example, "The toll has been paid successfully." The second prompt message can be generated based on preset corpus, or can be set independently according to the car owner's personal habits.

In a specific example, step S3 also includes:

Perform voice recognition on the first voice command to obtain voice features and voice text, and determine whether the voice features are consistent with the pre-stored voice features of the car owner; if they are consistent and the voice text indicates that the automatic payment mode has been entered, the automatic payment mode will be entered. mode; if they are inconsistent or the voice text indicates entering the manual payment mode, the manual payment mode will be entered.

Specifically, determining whether the voice characteristics are consistent with the pre-stored voice characteristics of the car owner is to verify the identity of the car owner and determine whether it is a voice command issued by the car owner. The vehicle will pre-store the voice characteristics of the car owner locally. If it is not a voice command issued by the car owner, , then there is no authority to control the car assistant to perform automatic payment operations; when the current voice characteristics recognized are consistent with the pre-stored voice characteristics of the car owner, it means that it is a voice command issued by the car owner. At this time, the voice command issued by the car owner may be an agreement to perform automatic payment. Or prohibit automatic payment, and specifically determine whether to enter automatic payment mode or manual payment mode based on the voice text.

Preferably, it can also be specifically set to:

If during the first verification, it is determined that the voice characteristics are inconsistent with the pre-stored voice characteristics of the car owner and the verification cannot be passed, the voice prompt message will be output again to prompt for re-verification. If the verification fails for a total of 3 times, the automatic payment operation will be exited and a voice prompt will be output. The message prompts you to enter manual payment mode.

In a specific example, step S4 also includes:

When the first toll bill and the second toll bill are inconsistent, determine whether the toll error between the two is within a preset error range;

Specifically, the preset error range is the cost tolerance deviation set by the car owner in the vehicle assistant system in advance, for example, the cost error is in the range of +/-3 yuan.

If it is within the preset error range, when the vehicle reaches the entrance and exit of the toll section, the on-board assistant interacts with the payment platform based on the second toll bill to complete the payment;

Specifically, for example, if the cost error is within the range of +/-3 yuan, the in-vehicle assistant will only report the deviation and will not ask the car owner whether to accept it, but will accept it by default to reduce tedious operations and improve the efficiency of the system.

If it is not within the preset error range, a third prompt message for requesting the driver to confirm payment is output, and when the on-board assistant receives the second voice command from the driver, it determines whether to continue execution based on the second voice command. Automatic payment mode or jump to manual payment mode; if the automatic payment mode continues, when the vehicle reaches the exit of the toll section, the on-board assistant interacts with the payment platform according to the second toll bill to complete the payment.

Specifically, if the fee deviation range of +/-3 yuan is exceeded, the in-car assistant will continue to ask "Do you accept it" by voice, and the car owner can issue voice instructions to select "Confirm" or "Do not accept" according to the actual situation. If the car owner chooses "Do Not Accept", the voice prompt will enter the manual payment mode. If the car owner chooses "Confirm", he will continue to stay in the automatic payment mode to avoid being arbitrarily charged by some systems or having his card stolen by illegal systems.

In a specific example, the method further includes steps Steps 11 to 14:

Step Step 11. While the vehicle is driving, the vehicle-mounted assistant periodically searches the map through the Internet for all toll road section entrances whose straight-line distance from the vehicle is ≤ the second preset distance threshold;

For example, the scene diagram of the toll road section is shown in Figure 2. The second preset distance threshold is 5km. After the vehicle starts the engine, the in-vehicle assistant automatically opens in the background and uses the vehicle's driving direction, vehicle GPS positioning information and vehicle Based on the image information of the front camera, such as which road and lane the vehicle is currently on, combined with real-time map traffic conditions, such as whether it is smooth, congested, or traffic controlled, the straight-line distance to the vehicle is periodically searched on the map through the Internet. Entrances to all toll roads within a range of ≤5km; Step 11 is an intelligent search;

Step Step 12: Obtain vehicle positioning information, and perform simulated navigation based on the vehicle positioning information, the entrances to all toll road sections, and map data to obtain the navigation distance between the vehicle and the entrances to all toll road sections;

Specifically, step Step12 is a secondary intelligent search based on the search result of step Step11. Assuming that the search result of step Step11 obtains 5 toll road section entrances, the shortest route planning mode is selected through the route planning mode in the current simulated navigation, based on the current position of the vehicle. The location is the starting point. From the starting point, real route search and planning are carried out for the entrance targets of these five toll road sections, and the length of the actual route is calculated, which is the real shortest distance from the starting point to the target location, which is also the shortest distance for vehicles to reach the entrance of the toll station. distance, thereby obtaining 5 real distance values, that is, navigation distance; it should be noted that when simulating navigation, there will be multiple different navigation routes for the same target location, and the distances of different navigation routes are different. In this embodiment, the shortest is selected Navigation routes calculate navigation distance.

It should be noted that the simulated navigation is based on the current real-time status of the vehicle, including the current location, the direction of the vehicle, the lane in which the vehicle is located (such as going straight, turning left, making a U-turn, etc.), and the location of the target location, in accordance with traffic laws and regulations. , when the vehicle is driving legally, for example, considering that the straight lane may restrict turning, the turning lane may restrict straight driving, the left-turn lane may restrict U-turns, etc., several paths that the vehicle takes to reach the target location can be planned to obtain many feasible routes. , is a feasible route obtained by simulating the process of a vehicle traveling from the starting point to the end point. These lines have a variety of attributes, such as actual distance, running time, driving safety (such as major roads, small roads), etc., and additional fees will be incurred when passing through tolled road sections. However, the distance results searched in the existing map search function are all straight-line distances, which is not convenient enough. For example, if a gas station directly opposite the road where the vehicle is located is searched on the map, the search result is that the distance from the vehicle to the gas station is 20m. However, in actual road conditions, the vehicle may need to go straight for 6km before turning around to the opposite side of the current road. That is to say , the actual driving distance is more than 12km. However, using the above-mentioned secondary intelligent search mode, the actual distance of the gas station obtained is 12km, not 20m. This is where this search method is more scientific and convenient.

Step Step 13: Screen out all target toll road section entrances whose navigation distance to the vehicle is ≤ the third preset distance threshold, obtain the platform information of the toll management platform corresponding to all target toll road section entrances, and sort the toll management platforms according to the navigation distance from shortest to The far sorting method sorts all the target toll road section entrances to obtain the current management platform list; wherein the third preset distance threshold < the second preset distance threshold;

For example, the second preset distance threshold is 500m. The vehicle-mounted assistant searches in real time for the entrance to the toll road section within 500 meters from the vehicle according to the above-mentioned secondary intelligent search mode. Once the entrance to the toll road section is found, the vehicle-mounted assistant searches in real time. The toll management platform corresponding to the entrance of the toll road section is sorted according to the principle of nearest to far to obtain the current management platform list.

Step Step 14: Output the platform information of the first n toll management platforms in the current management platform list through voice broadcast to remind the driver; where n is a positive integer greater than 0.

Specifically, you can take the top 1-3 of the current management platform list, that is, n is 3, and briefly broadcast it to the car owner in voice mode, such as toll management platform A#, toll management platform B#, toll management platform C#, theoretically At this time, toll management platform A# is the closest; after outputting the platform information of the first n toll management platforms in the current management platform list through voice broadcast, return to the previous step to continue searching and refreshing the current management platform list ranking, with a refresh frequency of 10 seconds Every time when the results, sorting, etc. change, perform Step 14 again for a brief voice broadcast.

In a specific example, the method further includes steps Step21-22:

Step 21. When there is a navigation distance between at least one toll section entrance and the vehicle ≤ the fourth preset distance threshold, the vehicle assistant establishes a communication connection with the toll management platform of the first n toll sections based on the preset car owner account, and Interact with the toll management platform of one or more toll road sections to obtain vehicle entry information.

Specifically, the fourth preset distance threshold may be 200m. That is, according to the above-mentioned secondary intelligent search mode, the vehicle assistant searches for a vehicle within 200 meters of the entrance of any toll section, and the vehicle assistant starts to automatically connect to the n toll management sections with the preset vehicle access account containing the vehicle owner information. Toll management platforms, such as toll management platform A#, toll management platform B#, and toll management platform C#. Theoretically, toll management platform A# is the closest at this time and starts to automatically cycle and query the status of vehicles on these three toll management platforms. Vehicle admission information.

Step 22. When the vehicle enters the entrance of a certain toll road section, the vehicle assistant determines that the vehicle has entered the certain toll road section based on the vehicle entry information obtained by interacting with the toll management platform of the certain toll road section, and outputs the username and password. The fourth prompt message is used to remind the owner that the vehicle has entered a certain toll road section.

Specifically, if the vehicle enters the road section entrance corresponding to the toll management system A# in the next short period of time, then the vehicle identification system of the toll management system A# must have confirmed the vehicle's entry. At this time, the toll management system A# must With the entry information of the vehicle, the on-board assistant can fully confirm that the vehicle has entered the toll management system A#. At this time, the on-board assistant briefly announces to the car owner in voice mode that it has entered the toll management system corresponding to A#. It should be noted that in this embodiment, the vehicle-mounted assistant searches for vehicle entry information in toll management system A#, toll management system B#, and toll management system C# in a loop. The vehicle-mounted assistant can always find an accurate matching one or 0, 0 It means that the vehicle has not entered, because sometimes there are multiple very close intersections that can generate tolls, and this function is needed to accurately and intelligently confirm the vehicle's entry status.

In summary, the method of this embodiment has the functions of autonomous positioning, intelligent distance search method to filter targets, active confirmation of the entered toll road section, automatic interaction with the smart toll management system, automatic calculation of tolls according to the current toll management system charging standards, etc. A series of complementary and organically combined closed-loop functions such as fees, voice recognition and execution of car owner instructions, and autonomous payment.
