Description

Technical Field

[0001] The present invention relates to the technical field of vehicle electronic control, and in particular to a method, device and medium for controlling the communication state of a vehicle-mounted unit. Background Art

[0002] ETC (Electronic Toll Collection) is a service function of the Intelligent Transportation System. The ETC system primarily consists of a backend system, lane controllers, roadside units (RSUs), and on-board units (OBUs). When a vehicle passes through an ETC lane, the lane's RSU communicates with the vehicle's OBU to identify the vehicle, and the backend system calculates and deducts the toll. Passing vehicles do not need to stop at the intersection, enabling automatic vehicle identification and toll collection.

[0003] In the current application stage, the detection range of the RSU on the ETC lane is slightly larger to meet the needs of different vehicle models and avoid the situation where all vehicles are required to approach the RSU at a low speed before the gate is opened, which reduces the overall traffic efficiency. However, the inventors have found that the existing technology has at least the following problems: when the OBU of the ETC system of the leading vehicle is abnormal or the leading vehicle enters the ETC lane without an ETC system, due to the larger detection range of the RSU, the rear vehicle enters the detection area of ​​the RSU. The toll gate is opened by the OBU of the rear vehicle, but the leading vehicle mistakenly uses the ETC of the rear vehicle to complete the passage, resulting in the rear vehicle being unable to pass. At this time, manual processing is required, which in turn reduces the traffic efficiency of the rear vehicle. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide a method, device and medium for controlling the communication status of a vehicle-mounted unit, which can effectively improve the ETC recognition accuracy and improve the vehicle's traffic efficiency.

[0011] Determining whether the vehicle is about to enter an ETC toll gate based on image information in front of the vehicle at the current moment;

[0012] After determining that the vehicle is about to enter the ETC toll gate, it is determined whether there is no object blocking the ETC toll gate based on the image information in front of the vehicle at the current moment.

[0013] As an improvement to the above solution, the environmental information further includes a radar signal detected by the vehicle, and the preset ETC charging condition further includes the absence of an unpassed object in front of the vehicle; and after determining that there is no object blocking the ETC charging pole, the determining, based on the environmental information, whether the environment in which the vehicle is located satisfies the preset ETC charging condition further includes:

[0014] It is determined whether there is no non-passing object in front of the vehicle according to the radar signal detected by the vehicle.

[0015] As an improvement to the above solution, judging whether the vehicle is about to enter the ETC toll gate based on the image information in front of the vehicle at the current moment specifically includes:

[0016] Performing feature information recognition on image information in front of the vehicle at the current moment;

[0017] Based on the identified feature information, it is determined whether there is preset identification feature information in the image information to determine whether the vehicle is about to enter the ETC toll gate; wherein the preset identification feature information is used to characterize the ETC toll gate.

[0018] As an improvement to the above solution, the preset identification characteristic information is "ETC" character characteristic information.

[0019] As an improvement to the above solution, the determining whether there is no object blocking the ETC toll pole based on the image information in front of the vehicle at the current moment specifically includes:

[0020] Performing feature information recognition on image information in front of the vehicle at the current moment;

[0021] Based on the identified feature information, it is determined whether the image information contains complete feature information of the ETC toll pole, so as to determine whether there is no object blocking the ETC toll pole.

[0022] As an improvement to the above solution, after controlling the onboard unit to be in a communication-disabled state, the method further includes:

[0023] Receive status control instructions from the user;

[0024] According to the state control instruction of the user, the vehicle-mounted unit is controlled to be in a communication-allowed state.

[0025] An embodiment of the present invention further provides a communication status control device for a vehicle-mounted unit, comprising:

[0026] Environmental information monitoring module, used to monitor the environmental information of the vehicle in real time after the vehicle is powered on;

[0027] An ETC charging condition judgment module is used to judge whether the environment in which the vehicle is located meets the preset ETC charging conditions based on the environmental information;

[0031] An embodiment of the present invention also provides a computer-readable storage medium, which includes a stored computer program, wherein when the computer program is running, the device where the computer-readable storage medium is located is controlled to execute the communication status control method of the vehicle-mounted unit as described in any one of the above.

[0032] Compared to the prior art, the present invention discloses a method, device, and medium for controlling the communication status of an on-board unit (OVU). After the vehicle is powered on, the system monitors environmental information of the vehicle's surroundings in real time. Based on this environmental information, it determines whether the vehicle's surroundings meet preset ETC charging conditions. If the vehicle's surroundings meet the preset ETC charging conditions, the OVU is controlled to a communication-enabled state; if the vehicle's surroundings do not meet the preset ETC charging conditions, the OVU is controlled to a communication-disabled state. Using the present invention, when the ETC charging conditions are met, the OVU communicates normally to facilitate ETC operation with the roadside unit (RSU). When the ETC charging conditions are not met, the OVU disables communication. This effectively prevents the misuse of ETC by preceding vehicles due to the RSU's excessively wide detection range in the ETC lane. This reduces the hassle of manual processing, significantly improves ETC recognition accuracy, and enhances vehicle traffic efficiency. Furthermore, the present invention eliminates the need to adjust the detection range of the RSU in the ETC lane, thus ensuring the overall traffic efficiency of the ETC lane to a certain extent.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figure 1 , is a schematic diagram of the steps of a method for controlling the communication status of a vehicle-mounted unit in a first embodiment of the present invention. A method for controlling the communication status of a vehicle-mounted unit provided by an embodiment of the present invention is performed by following steps S1 to S4:

[0042] S1. After the vehicle is powered on, the environmental information of the vehicle's environment is monitored in real time.

[0043] S2. Determine, based on the environmental information, whether the environment in which the vehicle is located meets preset ETC charging conditions.

[0044] S3. If the environment in which the vehicle is located meets the preset ETC charging conditions, control the on-board unit to be in a communication-allowed state.

[0045] S4. If the environment in which the vehicle is located does not meet the preset ETC charging conditions, control the on-board unit to be in a communication-disabled state.

[0046] It should be noted that the onboard unit (OBU) installed on the vehicle is a component of the ETC system, also known as an electronic tag or transponder. The OBU stores the vehicle's identity information and serves as a "pass" for each vehicle to pass through the toll booth. When the OBU is in a communication-enabled state, it transmits a microwave signal in real time so that the roadside unit (RSU) in the ETC lane can receive the microwave signal, communicate with the OBU, and thus identify the vehicle's identity information to complete the ETC toll deduction operation.

[0047] In an embodiment of the present invention, in order to avoid the situation where the preceding vehicle enters the detection area of ​​the roadside unit and the toll gate is opened by the preceding vehicle due to an ETC system anomaly or the preceding vehicle enters the ETC lane without an ETC system, the preceding vehicle mistakenly uses ETC to pass through. After the vehicle is powered on, the environmental monitoring sensors installed on the vehicle monitor the environmental information of the vehicle in real time. After processing and analyzing the monitored environmental information, it is used to determine in real time whether the current environment meets the preset ETC charging conditions, thereby controlling the communication status of the vehicle-mounted unit.

[0048] Specifically, when the vehicle's environment meets the preset ETC charging conditions, the onboard unit is controlled to be in a communication-enabled state, enabling it to send microwave signals in real time to communicate with the roadside unit. When the vehicle's environment does not meet the preset ETC charging conditions, the onboard unit is controlled to be in a communication-disabled state, preventing it from sending microwave signals. In this case, even if the vehicle enters the roadside unit's detection range, it cannot be identified by the roadside unit and ETC toll deduction cannot be completed.

[0049] Embodiment 1 of the present invention provides a method for controlling the communication status of an on-board unit. After the vehicle is powered on, the method monitors the environmental information of the vehicle's environment in real time. Based on the environmental information, the method determines whether the vehicle's environment meets the preset ETC charging conditions, thereby controlling the communication status of the on-board unit. When the ETC charging conditions are met, the on-board unit communicates normally to facilitate cooperating with the roadside unit to complete the ETC operation. When the ETC charging conditions are not met, the on-board unit prohibits communication. The present invention can effectively avoid the situation where the detection range of the roadside unit on the ETC lane is too large, resulting in the misuse of ETC by the preceding vehicle, thereby reducing the trouble caused by manual processing, greatly improving the ETC recognition accuracy, and improving the vehicle's traffic efficiency. In addition, the present invention does not require adjustment of the detection range of the roadside unit on the ETC lane, thereby ensuring the overall traffic efficiency of the ETC lane to a certain extent.

[0050] As a preferred embodiment, see Figure 2 , is a schematic diagram of the steps of a method for controlling the communication status of an onboard unit in a second embodiment of the present invention. The second embodiment of the present invention is further implemented on the basis of the first embodiment, wherein the environmental information includes image information in front of the vehicle. Then step S2 specifically includes steps S21 to S22:

[0051] S21. Determine whether the vehicle is about to enter an ETC toll gate based on image information in front of the vehicle at the current moment;

[0052] S22. After determining that the vehicle is about to enter the ETC toll gate, determine whether there is no object blocking the ETC toll gate based on the image information in front of the vehicle at the current moment.

[0053] In an embodiment of the present invention, the environment monitoring sensor for monitoring the environment information of the vehicle includes a front camera of the vehicle. Figure 3, a schematic diagram of image information in front of a vehicle in Embodiment 2 of the present invention. After the vehicle is powered on, the vehicle's front camera activates, identifying image information in front of the road in real time and transmitting it to the vehicle's central controller. The central controller processes the received image in real time to determine whether it meets the ETC charging conditions.

[0054] Preferably, step S21 specifically includes:

[0055] S211, performing feature information recognition on the image information in front of the vehicle at the current moment;

[0056] S212. Determine whether there is preset identification feature information in the image information based on the identified feature information, so as to determine whether the vehicle is about to enter the ETC toll gate; wherein the preset identification feature information is used to characterize the ETC toll gate.

[0057] The vehicle's central controller pre-stores identification feature information used to characterize the ETC toll gate. Upon receiving image information from the vehicle's front, the central controller performs feature recognition on the image information and compares it with the stored identification feature information. If it determines that the image information contains the preset identification feature information, indicating that the vehicle is about to enter the ETC toll gate, the central controller continues to receive and process the image information monitored at the current moment to determine whether there are any objects obstructing the ETC toll gate. Otherwise, indicating that the vehicle has not yet entered the ETC toll gate, the central controller continues to receive and process the image information detected at the current moment to determine whether it is about to enter the ETC toll gate.

[0058] Preferably, see Figure 3 The preset identification feature information is the "ETC" feature information. That is, when the "ETC" feature information appears in the image information in front of the vehicle, it indicates that the vehicle is about to enter the ETC toll gate.

[0059] It can be understood that the preset identification characteristic information can also be the characteristic information of the words "Electronic Toll Collection System", or any other characteristic information used to characterize the ETC toll gate. It can be set and stored according to actual conditions without affecting the beneficial effects achieved by the present invention.

[0060] Preferably, step S22 specifically includes:

[0061] S221, performing feature information recognition on the image information in front of the vehicle at the current moment;

[0062] S222. Determine whether the image information contains complete feature information of the ETC toll pole based on the identified feature information, so as to determine whether there is no object blocking the ETC toll pole.

[0063] The central controller of the vehicle has pre-stored the complete feature information of the ETC toll gate. After determining that the vehicle is about to enter the ETC toll gate, the central processor continues to receive the image information in front of the vehicle monitored by the front camera, performs feature recognition on the image information, and compares it with the stored complete feature information of the ETC toll gate. If it is determined that the image information contains the complete feature information of the ETC toll gate, for example Figure 3 As shown in the third schematic diagram, vehicle B is able to recognize the complete image of the ETC toll pole, indicating that there is no object blocking the ETC toll pole within the straight-line visual range between the front camera and the toll pole. At this time, it can be determined that the environment in which the vehicle is located meets the preset ETC charging conditions, and the on-board unit is controlled to be in a communication-allowed state.

[0064] If it is determined that the image information does not contain complete ETC toll pole feature information, for example Figure 3 As shown in the first and second schematic diagrams, when vehicle A is traveling normally in front of vehicle B, or vehicle A is passing through an ETC toll pole, it indicates that there is an object blocking the ETC toll pole within the straight-line visual range between the front camera and the toll pole. At this time, it is determined that the environment in which the vehicle is located does not meet the preset ETC charging conditions, and the on-board unit is controlled to be in a communication prohibited state.

[0065] In an embodiment of the present invention, the front camera of the vehicle monitors the image information in front of the vehicle in real time and transmits it to the central processing unit in real time. The central processing unit also receives the image information in real time and performs image recognition and analysis in real time, thereby ensuring that the environmental information in front of the vehicle changes all the time during the continuous driving of the vehicle, and can also obtain the most timely environmental information, thereby improving the accuracy of judging whether the ETC charging conditions are met and improving the accuracy of controlling the communication status of the on-board unit.

[0066] It is understandable that in order to ensure that the vehicle can be in a normal ETC functional state as much as possible, the default communication state of the on-board unit can be set to a communication-allowed state after the vehicle is powered on.

[0067] Embodiment 2 of the present invention provides a method for controlling the communication status of a vehicle-mounted unit. After the entire vehicle is powered on, image information in front of the vehicle is obtained in real time through the vehicle's front camera, and based on the image information, it is judged whether the vehicle is about to enter the ETC toll gate and whether there is no object blocking the ETC toll pole, thereby realizing the judgment of whether the environment in which the vehicle is located meets the ETC charging conditions, and then realizing the control of the communication status of the vehicle-mounted unit. While ensuring the normal ETC function of the vehicle, it can effectively avoid the situation where the ETC is misused by the preceding vehicle due to the large detection range of the roadside unit on the ETC lane, thereby greatly improving the ETC recognition accuracy and improving the vehicle's traffic efficiency.

[0068] See also Figure 4 , is a schematic diagram of the steps of a method for controlling the communication state of an onboard unit in a third embodiment of the present invention. The third embodiment of the present invention is further implemented on the basis of the second embodiment, wherein the environmental information also includes a radar signal detected by the vehicle.

[0069] Furthermore, the step S2 further includes step S23:

[0070] S23. After determining that there is no object blocking the ETC toll pole, determine whether there is no non-passing object in front of the vehicle based on the radar signal detected by the vehicle.

[0071] In an embodiment of the present invention, the environmental monitoring sensor used to monitor the vehicle's surroundings also includes a front radar device. After the vehicle is powered on, the front radar activates, sending radar detection signals in real time, receiving returned radar echo signals, and transmitting them to the vehicle's central controller in real time. Based on the received radar signals, the central controller determines whether there are any unpassed objects in front of the vehicle.

[0072] It should be noted that the objects that are not passing include pedestrians or vehicles traveling in front of the vehicle.

[0073] When the front camera of the vehicle detects a complete ETC toll pole, in order to avoid the possibility that a vehicle with a low body height or a pedestrian passing in front of the vehicle cannot be captured by the front camera of the vehicle and thus cause a misjudgment, the embodiment of the present invention uses radar signals for auxiliary judgment. After processing and analyzing the radar signal detected by the radar device, if it is determined that there is an object that has not passed, for example Figure 3 As shown in the first and second schematic diagrams in FIG, the current vehicle environment still does not meet the ETC charging conditions, and the vehicle-mounted unit is controlled to be in a communication-prohibited state; when the radar signal detected by the radar device is processed and analyzed, it is determined that there is no non-passing object, for example Figure 3In the case shown in the third schematic diagram, combined with the judgment result of the image information monitored by the front camera, it is determined that the current vehicle environment meets the ETC charging conditions, and the on-board unit is controlled to be in a communication-allowed state, so that the on-board unit and the roadside unit on the ETC lane can communicate normally and lift the ETC charging bar normally to release the vehicle, for example Figure 3 The situation is shown in the fourth schematic diagram in FIG.

[0074] Embodiment 3 of the present invention provides a method for controlling the communication status of a vehicle-mounted unit. After the entire vehicle is powered on, image information in front of the vehicle is obtained in real time through the vehicle's front camera, and based on the image information, it is determined whether the vehicle is about to enter the ETC toll gate and whether there is no object blocking the ETC toll pole. The vehicle's front radar monitors the radar signal in real time to determine whether there is no unpassed object in front of the vehicle, thereby realizing the judgment of whether the environment in which the vehicle is located meets the ETC charging conditions, and then realizing the control of the communication status of the vehicle-mounted unit. While ensuring the normal ETC function of the vehicle, it can effectively avoid the situation where the ETC is misused by the preceding vehicle due to the large detection range of the roadside unit on the ETC lane, thereby greatly improving the ETC recognition accuracy and improving the vehicle's traffic efficiency.

[0075] As a preferred embodiment, based on any one of the first to third embodiments, after the onboard unit is controlled to be in a communication-disabled state, the communication state control method of the onboard unit further includes step S5:

[0076] S5. Receive a status control instruction from the user; and control the onboard unit to be in a communication-allowed state according to the status control instruction from the user.

[0077] To prevent the OMU from entering a communication-disabled state under certain operating conditions and being unable to exit due to inaccurate image recognition or radar signal monitoring, thus affecting normal ETC functionality, an embodiment of the present invention includes a manual reset switch for receiving user status control commands. When the OMU is in the communication-disabled state, the user can press the manual reset switch as needed to restore communication with the OMU.

[0078] It can be understood that the manual reset switch is only an optional implementation method. In actual applications, other methods such as inputting the status control instructions through the vehicle-mounted central control screen can also be used to restore the communication of the vehicle-mounted unit, which will not affect the beneficial effects achieved by the present invention.

[0079] The technical means of the embodiments of the present invention can effectively ensure the normal execution of the ETC function of the vehicle, improve the vehicle's traffic efficiency, and further improve the user's car experience.
