DETAILED DESCRIPTION

[0015] The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0016] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0017] In related technologies, when positioning signals are inaccurate, the navigation server will send warning messages to unrelated vehicles, causing them to incorrectly change lanes or slow down, leading to traffic jams. For example, when a vehicle is traveling on a multi-layered road section, the vehicle is on the upper road, but the positioning result is on the lower road. This will cause the navigation server to incorrectly send warning messages to vehicles on the lower road, causing them to incorrectly change lanes or slow down, resulting in traffic jams.

[0018] In addition, the navigation server can only send warning information to vehicles or terminals that have the same navigation application open, while vehicles traveling on the same road but not using the same navigation application cannot receive the warning information.

[0019] Based on the problems existing in the related technologies, the embodiment of the present application provides a new abnormal parking reminder method, which obtains the road section information where the abnormal parking incident occurs through the on-board ETC unit. Since the vehicle communicates with the communication device installed on the gantry every time it approaches a gantry during driving, the gantry and the vehicle are in the same road section during the communication process. In addition, the gantry is set at a fixed position on the road. After determining the gantry where the communication device communicating with the on-board ETC unit is located, the road section information where the abnormal parking incident occurs can be accurately located. The vehicle then reports the positioning result to the server, and the server sends the reminder information to the target vehicle that is about to pass through the same road section. The target vehicle can take lane change measures or deceleration measures in time to reduce the probability of accidents and improve traffic safety. In addition, the present application does not rely on the navigation server to forward data. Even if other vehicles do not use the navigation application, they can receive the reminder information and then control the vehicle to take avoidance measures, further improving traffic safety.

[0020] Example 1 This application embodiment introduces the implementation environment of the abnormal parking reminder method, please refer to Figure 1 , the implementation environment includes a vehicle 100 and a server 200.

[0021] In an embodiment of the present application, a vehicle 100 includes an onboard ETC unit 110, which may be an onboard electronic tracking unit (OBU). When a gantry 300 is installed on the road (e.g., a highway) on which the vehicle 100 is traveling, and a communication device 310 is mounted on the gantry 300, when the vehicle 100 approaches the gantry 300, the communication device 310 transmits a signal to the onboard ETC unit 110, which responds to the signal, transmitting relevant information about the vehicle 100, such as the vehicle model and license plate number. The communication device 110 may be a microwave antenna (RSU). During this process, the gantry 300 and the vehicle 100 are located on the same road section. Each gantry 300 has a unique identifier and is assigned a fixed road section. Therefore, the road section currently occupied by the vehicle 100 can be determined based on the gantry 300 where the communication device 310 communicating with the vehicle's onboard ETC unit 110 is located.

[0022] In an embodiment of the present application, the vehicle 100 further includes a plurality of on-board sensors, a vehicle controller, and a communication module. The plurality of on-board sensors include but are not limited to: a speed sensor, an acceleration sensor, a steering wheel angle sensor, a temperature sensor, and the like. The on-board sensors are used to detect the driving parameters and state parameters of the vehicle and report them to the vehicle controller. The vehicle controller is used to detect whether an abnormal parking event has occurred based on the detection values ​​of the plurality of on-board sensors. The communication module is used to communicate with the server 200, for example, to report to the server 200 the road section information where the abnormal parking event occurred. The communication module can be a Tbox in the vehicle.

[0023] Based on the abnormal parking information reported by vehicle 100, server 200 sends a reminder message to other vehicles about to pass the road section where the abnormal parking incident occurred, so as to remind other vehicles to take evasive measures. Server 200 can be a single server, a server cluster consisting of multiple servers, or a cloud computing service center.

[0024] Example 2 This application embodiment introduces a method for reminding abnormal parking. Figure 1 For the vehicles in the implementation environment shown, please refer to Figure 2 , the method includes the following process.

[0025] S10, monitoring whether an abnormal parking event occurs.

[0026] While the vehicle is driving, the vehicle's driving parameters and status parameters are obtained through on-board sensors, and whether an abnormal parking event occurs is monitored based on the vehicle's driving parameters and status parameters.

[0027] In some embodiments, the vehicle-mounted sensor includes a speed sensor, and whether the vehicle is stopped is determined by the detection value of the speed sensor.

[0028] In some embodiments, the vehicle's onboard sensors include an acceleration sensor. The vehicle controller obtains at least one detection value of the acceleration sensor before the vehicle stops. If the detection value is greater than a preset value, an abnormal parking event is determined. The preset value is set based on experimentation or experience and indicates that the vehicle is rapidly decelerating.

[0029] In some embodiments, the vehicle's onboard sensors include a steering wheel angle sensor. The vehicle controller obtains at least one detection value of the steering wheel angle sensor before the vehicle stops, and determines that an abnormal parking event has occurred if the rate of change of the detection value is greater than a preset rate of change. The preset rate of change is set based on experimentation or experience and indicates that the vehicle is making a sharp turn.

[0030] In some embodiments, the vehicle's onboard sensors include a temperature sensor for detecting the temperature of the drive system. The vehicle controller obtains at least one detection value from the temperature sensor before the vehicle stops. If the detection value is greater than a preset temperature, an abnormal stop event is determined. For new energy vehicles, the drive system includes a motor; for gasoline vehicles, the drive system includes an engine. The preset temperature is set based on experimentation or experience and indicates that the vehicle's drive system is overheated.

[0031] In some embodiments, the vehicle-mounted sensor includes a camera, and the vehicle controller obtains the image taken by the camera after the vehicle is parked and recognizes the image. If it is recognized that the vehicle is parked in a non-emergency lane or in the middle of the road, it is determined that an abnormal parking event has occurred.

[0032] In some embodiments, the vehicle controller may further monitor whether a hazard warning message is issued after the vehicle stops. If a hazard warning message is issued after the vehicle stops, it is determined that an abnormal parking event occurs for the vehicle.

[0033] The vehicle may also monitor whether an abnormal parking event occurs through other means, which is not limited in the embodiments of the present application.

[0034] S20, when an abnormal parking event is detected, obtaining road information where the abnormal parking event occurred through the vehicle-mounted ETC unit.

[0035] Every time a vehicle approaches a gantry, the communication device installed on the gantry will send a signal to the on-board ETC unit, and the on-board ETC unit will reply to the signal to transmit information such as the vehicle model and license plate number. The above is a communication process between the on-board ETC unit and the communication device on the gantry. Among them, the signal sent by the communication device installed on the gantry to the on-board ETC unit includes at least the identification of the gantry (such as the number), and it may also include the identification of the above-mentioned communication device, vehicle information transmission instructions, timestamp, etc.

[0036] During the communication process between the on-board ETC unit and the communication device on the gantry, the gantry and the vehicle are in the same road section, and each gantry has a unique identifier and the road section is fixed. Therefore, the gantry where the communication device communicating with the vehicle's on-board ETC unit is located can determine the current road section of the vehicle.

[0037] S30, sending abnormal parking information to the server.

[0038] The abnormal parking information includes information about the road section where the abnormal parking incident occurred. The road section information about the abnormal parking incident may include geographical location information of the road section where the abnormal parking incident occurred, such as longitude and latitude. The road section information about the abnormal parking incident may also include an identifier of a gantry located within the road section.

[0039] Optionally, the abnormal parking information further includes a unique identifier of the vehicle, such as the vehicle license plate number, vehicle frame number, etc. Optionally, the abnormal parking information further includes the time when the abnormal parking event occurred.

[0040] Abnormal parking information instructs the server to send a reminder message to a target vehicle. A target vehicle is one that has traveled through the road section indicated by the road section information after an abnormal parking event. The preset duration is set based on experimentation or experience, for example, 10 minutes. Optionally, the reminder message includes information about the road section where the abnormal parking information occurred. Optionally, the reminder message also includes the identifier of the vehicle that experienced the abnormal parking event.

[0041] Optionally, the vehicle sends abnormal parking information to the server through tbox.

[0042] In summary, the technical solution provided by the embodiment of the present application obtains the road section information where the abnormal parking event occurred through the on-board ETC unit when an abnormal parking event is detected. Since the vehicle communicates with the communication device installed on the gantry every time it approaches a gantry during driving, the gantry and the vehicle are in the same road section during the communication process. In addition, the gantry is set at a fixed position on the road. By determining the gantry where the communication device communicating with the on-board ETC unit is located, the road section information where the abnormal parking event occurred can be accurately located. The vehicle then reports the positioning result to the server, and the server sends a reminder message to the target vehicle that is about to pass through the same road section. The target vehicle can take lane changing measures or deceleration measures in time to reduce the probability of accidents and improve traffic safety. In some embodiments, S30 includes S310 - S330 .

[0043] S310: Acquire first communication data from the communication data of the vehicle-mounted ETC unit.

[0044] The communication data of the on-board ETC unit refers to the communication data between the on-board ETC unit and the communication device installed on the gantry installed on the road where the vehicle is currently traveling. The communication data of the on-board ETC unit includes multiple communication data, each communication data corresponds to a communication process, and the multiple communication data are arranged in the order of timestamps. The first communication data refers to the communication data between the on-board ETC unit of the vehicle and the target communication device. The target communication device is the communication device with the shortest time interval between the timestamp of the communication data and the moment when the abnormal parking event occurred. Optionally, the vehicle controller obtains the communication data with the latest timestamp from the communication data of the on-board ETC unit as the first communication data.

[0045] S320: Acquire an identifier of a target gantry where the target communication device is installed from the first communication data.

[0046] As mentioned in the above embodiment, the signal sent by the communication device installed on the gantry to the on-board ETC unit includes at least the identification of the gantry, so the vehicle controller can directly determine the identification of the gantry carried in the first communication data as the identification of the target gantry.

[0047] S330: Determine the road section information where the abnormal parking event occurs according to the identification of the target gantry.

[0048] In some embodiments, the vehicle can directly determine the target gantry's identifier as the road section information where the abnormal parking event occurred. In other embodiments, the vehicle can obtain the geographic location information of the abnormal parking event based on the target gantry's identifier and a preset mapping relationship as the road section information where the abnormal parking event occurred.

[0049] As the vehicle approaches a gantry during driving, it will communicate with the communication device installed on the gantry. During the communication process, the gantry and the vehicle are on the same road section. In addition, the gantry is set at a fixed position on the road. Therefore, on the premise of determining the gantry where the communication device that communicates with the on-board ETC unit is located, the road section information where the abnormal parking incident occurred can be accurately located.

[0050] In some embodiments, S320-S330 can also be implemented as follows: if the time interval between the timestamp of the first communication data and the moment when the abnormal parking event occurs is less than a preset time interval, then the identification of the target gantry where the target communication device is installed is obtained in the first communication data, and the road section information where the abnormal parking event occurs is determined based on the identification of the target gantry.

[0051] The preset time interval is set based on experimentation or experience, for example, 5 minutes. If the time interval between the timestamp of the first communication data and the moment the abnormal parking event occurred is long, the vehicle may have left the current road. In this case, the distance between the vehicle and the target gantry is large, and the target gantry's identifier does not indicate the vehicle's actual current road section. Therefore, subsequent steps are not executed. This prevents the server from sending reminder messages to unrelated vehicles, preventing unrelated vehicles from erroneously changing lanes or slowing down based on the reminder message, thereby reducing traffic congestion.

[0052] Example 2 This application embodiment introduces a method for reminding abnormal parking. Figure 1 For the vehicles in the implementation environment shown, please refer to Figure 3 , the method includes the following process.

[0053] In some embodiments, before S20, the method further includes S40.

[0054] S40: Acquire lane information where the abnormal parking event occurs.

[0055] Optionally, the vehicle obtains an image captured by a camera and identifies the image to obtain lane information where the abnormal parking event occurred.

[0056] If the lane information indicates that the lane where the vehicle is currently parked is not an emergency lane, S20 is executed. If the lane information indicates that the lane where the vehicle is currently parked is an emergency lane, subsequent steps are not executed.

[0057] Since a vehicle parked in the emergency lane does not delay the normal travel of subsequent vehicles, there is no need to report to the server. In this case, the vehicle will not report abnormal parking information to the server, which can save vehicle communication resources. In addition, since the vehicle does not report abnormal parking information to the server, the server will not send a reminder message to the target vehicle, saving server communication resources.

[0058] In other embodiments, before S20, the vehicle may first obtain the wireless signal strength of the positioning module. If the wireless signal strength of the positioning module is less than a preset strength, S20 is executed. If the wireless signal strength of the positioning module is greater than or equal to the preset strength, the vehicle's current location is obtained through the positioning module. When the wireless signal of the positioning module is weak, the positioning may be inaccurate. In this case, the on-board ETC unit can obtain information about the road section where the abnormal parking event occurred, and accurately locate the location where the abnormal parking event occurred, thereby avoiding the situation where warning information is sent to unrelated vehicles due to inaccurate positioning when an abnormal parking event occurs.

[0059] In other embodiments, before S20, the vehicle may first obtain an image captured by a camera and identify the image captured by the camera to determine whether the vehicle is traveling on a specified road condition. If the vehicle is traveling on the specified road condition, S20 is executed. If the vehicle is not traveling on the specified road condition, the current position of the vehicle is obtained through the positioning module. The specified road condition refers to an overpass or a road section with overlapping multiple roads. When the vehicle is traveling on a specified road condition, the positioning result of the positioning module may be inaccurate. Therefore, by obtaining the road section information where the abnormal parking event occurred through the on-board ETC unit, the location where the abnormal parking event occurred can be accurately located, thereby avoiding the situation where an early warning message is sent to an unrelated vehicle due to inaccurate positioning when an abnormal parking event occurs.

[0060] In some embodiments, the vehicle executes S20 when it determines that it is traveling on a highway. Since most gantries are currently installed on highways, only when the vehicle is traveling on a highway will the road section where the abnormal parking incident occurred be located based on data exchange between the on-board ETC unit and the communication device on the gantry.

[0061] In some embodiments, after S30 , the abnormal parking reminder method further includes S50 .

[0062] S50: After monitoring that the vehicle has shifted to the emergency lane, a first notification message is sent to the server.

[0063] The first notification message instructs the server to stop sending reminder messages to the target vehicle. The first notification message can include the vehicle's identifier, such as the license plate number or vehicle frame number. The vehicle can obtain periodic camera images taken some time after the abnormal parking event occurs and use these images to monitor whether the vehicle has moved to the emergency lane.

[0064] Since a vehicle parked in the emergency lane will not delay the normal driving of subsequent vehicles, after detecting that the vehicle has moved to the emergency lane, the server is notified to stop sending reminder information to the target vehicle. On the one hand, this can avoid the target vehicle taking unnecessary deceleration and lane changing measures to cause traffic congestion, and on the other hand, it can save the server's communication resources.

[0065] In some embodiments, after S30 , the abnormal parking reminder method further includes S60 .

[0066] S60: After detecting that the vehicle has entered a normal driving state, a second notification message is sent to the server.

[0067] The second notification message instructs the server to stop sending reminder messages to the target vehicle. The second notification message can carry the vehicle's identifier, such as the license plate number or vehicle frame number. A vehicle in normal driving mode means it is operating within the speed limit specified on the road. The vehicle can obtain periodic speed sensor detection values ​​after a period of time following an abnormal parking event and use these values ​​to determine whether the vehicle has returned to normal driving mode.

[0068] After a vehicle enters the normal driving state, it will not delay the normal driving of subsequent vehicles. Therefore, after detecting that the vehicle has entered the normal driving state, on the one hand, it can avoid the target vehicle taking unnecessary deceleration and lane changing measures to cause traffic congestion, and on the other hand, it can save the server's communication resources.

[0069] Example 3 This application embodiment introduces a method for reminding abnormal parking. Figure 1 For servers in the implementation shown, refer to Figure 4 , the method includes the following process.

[0070] S410: Receive abnormal parking information sent by the vehicle.

[0071] Abnormal parking information includes information about the road section where the abnormal parking incident occurred. Abnormal parking information is obtained by the vehicle's onboard ETC unit when the vehicle detects an abnormal parking incident.

[0072] S420, determining a target vehicle.

[0073] The target vehicle refers to the vehicle that passes through the road section indicated by the road section information after an abnormal parking event occurs.

[0074] S430: Send a reminder message to the target vehicle.

[0075] The reminder information includes the road section information where the abnormal parking incident occurs. Optionally, the reminder information also includes the identification of the vehicle where the abnormal parking incident occurs, such as the license plate number and frame number.

[0076] The server can send a reminder message to the target vehicle's tbox. The target vehicle can announce the reminder message via voice or display it, such as on a heads-up display or on a central control screen. This can promptly alert the driver of the target vehicle to the presence of an abnormal parking event ahead, allowing the driver to promptly control the vehicle's speed reduction or lane change, thereby reducing the probability of a secondary accident caused by the vehicle behind failing to evade the abnormal parking event ahead.

[0077] To sum up, the technical solution provided by the embodiment of the present application is that the server can receive abnormal parking information sent by the vehicle, and determine the vehicle that is about to enter the road section where the abnormal parking incident occurred after the abnormal parking incident occurred based on the abnormal parking information, and send a reminder message to the determined vehicle. Since the vehicle communicates with the communication device installed on the gantry every time it approaches a gantry during driving, the gantry and the vehicle are in the same road section during the communication process. In addition, the gantry is fixed in a fixed position on the road. By determining the gantry where the communication device that communicates with the on-board ETC unit is located, the road section information where the abnormal parking incident occurred can be accurately located. In this way, the server can send the reminder message to the target vehicle in time, and the target vehicle can take lane changing measures or deceleration measures in time to reduce the probability of accidents and improve traffic safety.

[0078] In some embodiments, S420 includes S4210 - S4220 .

[0079] S4210, receiving communication data of the vehicle-mounted ETC unit sent by other vehicles.

[0080] The communication data of the on-board ETC units sent by other vehicles include the communication data between their on-board ETC units and the communication devices on each gantries they pass through.

[0081] S4220: If the second communication data exists in the communication data of the vehicle-mounted ETC unit sent by the other vehicle, the other vehicle is determined as the target vehicle.

[0082] The second communication data includes the identifier of the target gantry, and the timestamp of the second communication data is later than the timestamp of the first communication data. The presence of the second communication data in the communication data sent by the onboard ETC unit of the other vehicle indicates that the other vehicle is about to pass through the section of road where the abnormal parking event occurred after the abnormal parking event occurred.

[0083] The first communication data refers to the communication data between the vehicle's onboard ETC unit and the target communication device, and the target communication device refers to the communication device with the shortest time interval between the timestamp of the communication data and the time when the abnormal parking event occurs.

[0084] In some embodiments, after S430 , the abnormal parking reminder method further includes S440 .

[0085] S440: Receive a first notification message, and stop executing the steps of determining a target vehicle and sending a reminder message to the target vehicle according to the first notification message.

[0086] The first notification message is sent after the vehicle detects it has moved to the emergency lane. This prevents the server from sending reminder messages after the vehicle has moved to the emergency lane. This not only saves server communication resources, but also prevents the following vehicle from mistakenly changing lanes or slowing down, thus reducing traffic congestion.

[0087] In some embodiments, after S430 , the abnormal parking reminder method further includes S450 .

[0088] S450: Receive a second notification message, and stop executing the steps of determining a target vehicle and sending a reminder message to the target vehicle according to the second notification message.

[0089] The second notification message is sent after the vehicle detects that it has entered a normal driving state. This prevents the server from continuing to send reminder messages after the vehicle that experienced an abnormal parking incident has returned to a normal driving state. This not only saves server communication resources, but also prevents the following vehicle from mistakenly changing lanes or slowing down, thus reducing traffic congestion.

[0090] Example 5 This application embodiment introduces a method for reminding abnormal parking. Figure 1 For the implementation environment shown, please refer to Figure 5 , the method includes the following process.

[0091] S510: The vehicle monitors whether an abnormal parking event occurs.

[0092] S520: When an abnormal parking event is detected for a vehicle, the vehicle obtains information about the road section where the abnormal parking event occurs through the on-board ETC unit.

[0093] The communication data of the on-board ETC unit refers to the communication data between the on-board ETC unit and the communication device installed on the gantry set up on the road where the vehicle is currently traveling.

[0094] S530: The vehicle sends abnormal parking information to the server.

[0095] The abnormal parking information includes the road section information where the abnormal parking event occurs, and the abnormal parking information is used to instruct the server to send a reminder message to the target vehicle.

[0096] S540: The server determines the target vehicle.

[0097] The target vehicle refers to the vehicle that passes through the road section indicated by the road section information after an abnormal parking event occurs.

[0098] S550: Send a reminder message to the target vehicle.

[0099] To sum up, the technical solution provided by the embodiment of the present application obtains the road section information where the abnormal parking event occurs through the on-board ETC unit when an abnormal parking event is detected. Since the vehicle communicates with the communication device installed on the gantry every time it approaches a gantry during driving, the gantry and the vehicle are in the same road section during the communication process. In addition, the gantry is set at a fixed position on the road.
