Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Referring to fig. 1, a flowchart illustrating steps of an embodiment of a method for issuing driving route adjustments according to the present invention is shown, and is applied to a server, which is in communication with a plurality of vehicles.

In an embodiment of the invention, the server may communicate with the vehicle via a vehicle networking. Specifically, the networking may include an in-vehicle network, an inter-vehicle network between vehicles, and an in-vehicle mobile internet, so that the server may communicate with the plurality of vehicles through the inter-vehicle network, the in-vehicle mobile internet, and the like.

Step 101, receiving position reference information sent by a plurality of vehicles;

in the embodiment of the present invention, the server may receive the position reference information sent by the plurality of vehicles, so that the server may know the positions of the plurality of vehicles based on the position reference information.

The position reference information may be information for determining a position of the vehicle itself. As an alternative embodiment of the present invention, the position reference information may be positioning information, an image of an environment around the vehicle, information of a proximity reference object input by a user of the vehicle, or the like, which is not limited in this respect.

In a specific implementation, the plurality of vehicles may send the position reference information to the server in real time, so that the server may determine the positions of the plurality of vehicles in real time based on the position reference information sent by the plurality of vehicles.

Step 102, determining vehicle path sequencing according to the position reference information of the plurality of vehicles;

in the embodiment of the invention, the server can use the position reference information of the vehicles to know the positions of the vehicles, and further determine the path sequence of the vehicles on the lane of the road, so as to obtain the path sequence of the vehicles.

In a specific implementation, the server may determine the real-time position of the vehicle on a lane of a road by using the position reference information of the plurality of vehicles, and determine the path sequence of the plurality of vehicles on the lane of the road according to the driving mode of the vehicle, so as to obtain the vehicle path sequence.

103, when a road surface event is monitored, determining a target vehicle according to the vehicle travel sequencing;

in the embodiment of the invention, when the server monitors that the road surface events which may influence the driving of the vehicle exist, the target vehicle which may be influenced by the road surface events is determined according to the vehicle travel path sequence.

The road surface event may be an event that the vehicle driving may be affected by a vehicle collision accident on the road, water accumulation affecting safe driving of the vehicle on the road surface, a road blockage, partial lane closure or all lane closure of the road due to temporary construction, a temporary accident and the like, and the invention is not limited thereto.

In particular implementations, when the server monitors a road surface event, the server may determine at least one target vehicle that may be affected by the road surface event based on the vehicle travel sequence and the location of the road surface event.

Among the vehicles that may be affected by the road surface event may be a vehicle that is close to the place of the road surface event, a vehicle that is on the same lane as the place of the road surface event, or the like.

104, generating and issuing driving route modification information to the target vehicle; the driving route modification information is used to guide the target vehicle to modify a driving route.

In the embodiment of the present invention, the server may generate driving route modification information for prompting the target vehicle to modify the driving route, and issue the driving route modification information to the target vehicle. Therefore, the vehicle can acquire the driving route modification information sent by the server, so that the vehicle can know the road surface event which is difficult to know in real time by adopting the automatic driving system based on the driving route modification information. Thereafter, the vehicle may modify the driving route according to guidance of the driving route modification information. Therefore, the vehicle can know the road surface event and modify the driving route before the automatic driving system detects that the safety risk exists in the surrounding environment of the vehicle, so that the vehicle can be better ensured to run safely, and the safety of a driver is protected.

Referring to fig. 2, a flowchart illustrating steps of an embodiment of a method for issuing driving route adjustments according to the present invention is shown, and is applied to a server, which is in communication with a plurality of vehicles.

Step 201, receiving position reference information sent by a plurality of vehicles;

Step 202, determining the geographical ranges of the vehicles respectively by using the positioning information;

in an embodiment of the present invention, the position reference information may include positioning information. The positioning information may be a position of the vehicle in a preset map. The Positioning information may be determined by at least one of Positioning modes such as GPS (Global Positioning System), bluetooth Positioning, RFID (Radio Frequency IDentification), radar Positioning, laser Positioning, base station Positioning, and WiFi Positioning.

In an embodiment of the present invention, the positioning information may be used to determine a smaller geographic area in which the vehicle is located.

In a specific implementation, the vehicle may send the location information to the server in real time, so that the server may determine the geographic range of the vehicle on the road in real time based on the location information. Among the plurality of vehicles, there may be vehicles in different geographical ranges, or there may be vehicles in the same geographical range.

As an example of the present invention, the GPS positioning information of the vehicle a, the vehicle B, the vehicle C, and the vehicle D may all be (121.476898,31.230665), and the vehicle a, the vehicle B, the vehicle C, and the vehicle D are all in the same geographic range (121.476898, 31.230665).

Optionally, in a case where the distance between the plurality of vehicles on the road is large, the positioning information may be used to determine the vehicle path ranking of the vehicles on the road.

As an example of the invention, the vehicle can determine the position of the vehicle through GPS positioning, generate positioning information and send the positioning information to the server. The server may determine a vehicle within a geographical range of 3-5 meters in diameter in a high-precision map based on positioning information based on GPS positioning transmitted by the vehicle, and thereafter may determine a driving direction of the vehicle based on a plurality of positioning information transmitted by the vehicle, and further determine a lane in which the vehicle is located, thereby determining a real-time position of the vehicle on a road. Therefore, the real-time positions of the vehicles on the road can be obtained, the travel sequence of the vehicles on the road is determined, and the vehicle travel sequence is obtained.

Optionally, where the location information has a high degree of accuracy, then the location information may determine the real-time location of the vehicle on the road. In this case, the positioning information may be used to determine a vehicle path rank of the vehicle on the road.

As an example of the invention, the vehicle can be positioned by GPS and interacts with a preset RFID road unit, the position of the vehicle is determined, positioning information is generated and sent to the server. The server can accurately determine the real-time position of the vehicle on the road in a high-precision map according to the positioning information combining the GPS positioning and the RFID positioning. Therefore, the real-time positions of the vehicles on the road can be obtained, the travel sequence of the vehicles on the road is determined, and the vehicle travel sequence is obtained.

Step 203, aiming at least one vehicle in the same geographic range, determining vehicle characteristic information of other vehicles adjacent to the vehicle and/or determining road surface information by adopting the environment image information;

in an embodiment of the present invention, the position reference information includes environment image information. The environment image information is acquired by preset image acquisition equipment in the vehicle, so that the server can know the surrounding environment of the vehicle according to the environment image information and determine the position of the vehicle.

In particular, the vehicle may be provided with at least one image capturing device for capturing the surroundings of the vehicle, such as a vehicle recorder, a panoramic camera, a reversing camera, etc. According to the position of the image acquisition device, the image acquisition device can acquire images in different shooting directions and different shooting angle ranges. And combining the images acquired by at least one image acquisition device to obtain the environmental image information in the preset camera shooting range around the vehicle.

In the embodiment of the present invention, after determining the smaller geographic range where the vehicle is located, since the distance between the vehicles is short on the road with the larger traffic flow, there may be a plurality of vehicles in the same geographic range, and thus the rank of the paths between the vehicles in the same geographic range may not be well determined.

In this case, for at least one vehicle in the same geographic range, the environmental image information may be used to determine vehicle characteristic information of other vehicles adjacent to the vehicle, and/or road surface information may be used to determine a vehicle path rank of the plurality of vehicles using the positioning information and the environmental image information.

The vehicle characteristic information may be characteristic information for identifying a vehicle, such as license plate information, vehicle appearance, a marker set on the vehicle, an identification mark on the vehicle, and the like, which is not limited in the present invention.

In a specific implementation, the vehicle may be provided with license plates generally at the head of the vehicle as well as at the rear of the vehicle. In the environment image information of the vehicle, vehicle feature information of another vehicle immediately in front of the vehicle and adjacent to the vehicle may be extracted, and vehicle feature information of another vehicle immediately behind the vehicle and adjacent to the vehicle may also be extracted.

In a specific implementation, the environmental image information of the vehicle may also be used to extract road surface information of a road surface on which the vehicle is traveling. The road surface information can be road surface marks on a driving road of the vehicle, such as a direction mark, a vehicle speed mark and the like; and may also be a reference to a roadway surface, such as a railing, barrier, roadway edge trim, or the like.

Alternatively, when the environment image information includes a large amount of vehicle surrounding environment information, the vehicle travel sequence of the vehicle may be determined based on the environment image information.

In a specific implementation, the vehicle may send the environment image information to the server in real time, and the server may determine a real-time position of the vehicle on the road according to vehicle feature information, road surface identification, surrounding buildings, and the like included in the environment image information. After obtaining the environment image information of the plurality of vehicles, the environment image information may be used to determine real-time positions of the plurality of vehicles on the road, and determine a path sequence of the plurality of vehicles on the road, so as to obtain a vehicle path sequence.

Step 204, determining the vehicle travel path sequence of the plurality of vehicles by adopting the vehicle characteristic information and/or the road surface information;

in the embodiment of the present invention, after determining the vehicle characteristic information, and/or the road surface information, the vehicle characteristic information, and/or the road surface information may be used to determine the vehicle path sequence of the plurality of vehicles on the road.

In a specific implementation, after the geographic range of the vehicle on the road is determined by using the positioning information, vehicles adjacent to each other in the front-rear direction of the vehicle can be determined by using the vehicle characteristic information, so that the running path sequence between a plurality of vehicles in the same geographic range can be known, and the front-rear sequence between different geographic ranges can be determined according to the vehicle directions, so that the running path sequence of the vehicles on the road can be determined.

In a specific implementation, after the positioning information is used to determine the geographical range of the vehicle on the road, the road surface information may be used to determine the road surface mark or the road surface reference object photographed by the vehicle. Thereafter, the lane where the vehicle is located and the specific position in the lane can be determined based on the road surface mark or the road surface reference object and the distance between the vehicle and the road surface mark or the road surface reference object, so that the travel sequence among a plurality of vehicles in the same geographic range can be known. The front-back sequence between different geographic ranges can also be determined according to the vehicle direction, so that the vehicle travel path sequence of the vehicles on the road can be determined.

In a specific implementation, after determining the geographic range of the vehicle on the road, the positioning information may be used to determine vehicles adjacent to each other in the front-rear direction of the vehicle, and the road surface information may be combined to further determine the specific position of the vehicle and the lane where the vehicle is located, so that the travel sequence between multiple vehicles in the same geographic range may be known, and the front-back sequence between different geographic ranges may also be determined according to the vehicle direction, so that the travel sequence of the multiple vehicles on the road may be determined.

As an example of the present invention, the positioning information of the vehicle a, the vehicle B, the vehicle C, and the vehicle D may all be (121.476898,31.230665), and then the vehicle a, the vehicle B, the vehicle C, and the vehicle D are all in the same geographical range. Then, it is determined that the vehicle ahead of the vehicle a is the vehicle D, the vehicle ahead of the vehicle B is the vehicle C, the vehicle behind the vehicle C is the vehicle B, the vehicle ahead of the vehicle D is the vehicle E, and the vehicle behind the vehicle D is the vehicle a, by using the environment image information, it is known that the vehicles a, B, C, and D travel in two lanes, and the order of travel in the first lane is the vehicles C, B, and the second lane is the vehicles D and a, so that the vehicle path sequence of the plurality of vehicles on the road can be obtained.

Optionally, the image capturing device may be further configured to capture vehicle characteristic information of other vehicles on the left and right sides of the vehicle, so that the lane where the vehicle is located and the specific location where the vehicle is located may be further determined based on the vehicle characteristic information of the other vehicles on the left and right sides of the vehicle.

Alternatively, if the vehicle temporarily stops at the intersection and the vehicle can acquire the vehicle characteristic information of another vehicle having a different driving direction from the vehicle, the image acquisition device of the vehicle may be used to acquire the driving processes of a plurality of other vehicles having different driving directions, so that the image acquisition device of the vehicle may be used to determine the vehicle path sequence of the plurality of other vehicles.

Step 205, when a road surface event is monitored, determining a target vehicle according to the vehicle travel sequencing;

In one embodiment of the present invention, the step of determining a target vehicle according to the vehicle path ranking when a road surface event is monitored comprises:

s11, when a road surface event is monitored, determining at least one information sending range corresponding to the road surface event;

in the embodiment of the present invention, when the server monitors a road surface event, the server may determine at least one information transmission range corresponding to the road surface event based on an occurrence location of the road surface event. Vehicles within the information transmission range may be affected by the road surface event to varying degrees.

For example, the road surface event is a vehicle collision accident, and vehicles within a range of 10 meters behind the place of the vehicle collision accident may have a high possibility of a rear-end collision accident due to the influence of the vehicle collision accident. So that vehicles within the rear 10 meters range are more severely affected by road events.

Vehicles within a range of 10-100 meters behind the place where the vehicle collision accident occurs may have a low possibility of rear-end collision due to the influence of the vehicle collision accident, and the vehicles are difficult to normally run due to road congestion caused by the vehicle collision accident. Therefore, the vehicle within the range of 10-100 meters behind is affected by the moderate severity of the road surface event.

Vehicles within a range of 100-500 m behind the place where the vehicle collision accident occurs may have difficulty in normal driving due to road congestion caused by the vehicle collision accident. So that vehicles in the range of 100-500 meters behind can be affected by the lesser severity of the road event.

And S12, determining the target vehicle according to the information sending range and the vehicle travel path sequence.

In an embodiment of the invention, the road may have a plurality of lanes. When a road event occurs, the road event may affect vehicles in only a portion of the lanes. For example, a road has 6 lanes, of which 3 are driving north and 3 are driving south. If the road event is a vehicle collision accident occurring in the second south lane, the road event can only affect the vehicles running in the south direction within the preset range, and can not affect the vehicles running in the north direction. If the road surface event is that the first south lane has serious ponding, the road surface event can only influence the vehicles running on the first south lane within the preset range, and does not influence the vehicles on other lanes.

Therefore, when the road surface event is monitored, at least one target vehicle can be further determined in the vehicles within the information transmission range according to the information transmission range and the vehicle travel sequencing.

In a specific implementation, when a road surface event is monitored, at least one information transmission range can be determined according to the occurrence place of the road surface event, and at least one target vehicle influenced by the road surface event is determined in vehicles in the information transmission range according to the information transmission range and the vehicle travel sequencing.

In one embodiment of the invention, the method further comprises:

s21, when a road surface event is detected, determining a vehicle whose current navigation route includes the place of occurrence of the road surface event, and/or determining a vehicle that is about to pass through the place of occurrence of the road surface event as a target vehicle according to the driving route and the road passing direction.

In the embodiment of the present invention, there may be a case where a vehicle is not within the information transmission range, but the vehicle is about to pass through the place of occurrence of the route event, and the vehicle may be affected by the road surface time. For example, if the road surface event is a vehicle collision accident, a vehicle that is about to pass through the place of occurrence of the road surface event may be blocked due to the vehicle collision accident, resulting in an increased running time period.

Thus, when a road surface event is detected, a vehicle that is about to pass through the place of occurrence of the route event may also be determined as the target vehicle. Wherein the vehicle about to pass through the place of occurrence of the route event may include a vehicle whose current navigation route includes the place of occurrence of the road surface event, and/or a vehicle about to pass through the place of occurrence of the road surface event is determined according to the driving route and the road passing direction.

Specifically, the vehicle has a navigation function, so that a user can input a destination in the vehicle system, and the vehicle can generate a navigation route accordingly to guide the user to control the vehicle to travel by the navigation route. Thus, if the current navigation route of the vehicle includes the place of occurrence of the road surface event, the vehicle may be about to pass through the place of occurrence of the road surface event, so that the vehicle whose current navigation route includes the place of occurrence of the road surface event may be determined as the target vehicle;

specifically, the point where the vehicle is about to pass may be estimated according to the driving route of the vehicle on the road and the passing direction of the road, if the driving route of the vehicle on the road and the passing direction of the road are determined. Determining that the vehicle is about to pass the location of the road surface event, the road surface event may have an effect on the vehicle. Thus, a vehicle that is determined to be about to pass through the place of occurrence of the road surface event from the driving route and the road passing direction can be determined as the target vehicle.

Step 206, generating and issuing driving route modification information to the target vehicle; the driving route modification information is used to guide the target vehicle to modify a driving route.

In an embodiment of the present invention, the step of generating and issuing driving route modification information to the target vehicle includes:

s31, determining the severity of the road surface event according to the distance between the information sending range and the place of the road surface event;

in the embodiment of the present invention, the road surface event may have different degrees of influence on the target vehicles within the information transmission range according to the distance between the information transmission range and the place of occurrence of the road surface event, so that the server may transmit different driving route modification information to the target vehicles within different information transmission ranges.

Thus, it is possible to determine the event severity based on the distance between the information transmission range and the place of occurrence of the road surface event to determine the driving route modification information that the server needs to transmit to the information transmission range.

In particular implementations, the road surface events themselves may have different severity. For example, the road surface event is a vehicle collision accident, which may cause a rear-end collision of a vehicle behind, with high severity. The road surface event is a road surface having standing water, which may cause vehicles to be impassable, or cause vehicle damage, with moderate severity. The road surface event is a light blockage of the road, which may affect the driving speed of the vehicle, with a lesser severity.

Thereafter, the event severity may be determined based on the distance between the information transmission range and the location of the road surface event, as well as the severity of the road surface event itself.

For example, if the severity of the road surface event itself is high and the distance between the information transmission range and the place where the road surface event occurs is short, the road surface event has a high event severity for the target vehicles within the information transmission range. If the severity of the road surface event itself is high and the distance between the information transmission range and the place where the road surface event occurs is long, the road surface event has a moderate event severity for the target vehicles within the information transmission range. If the severity of the road surface event itself is low and the distance between the information transmission range and the place where the road surface event occurs is short, the road surface event has a moderate event severity for the target vehicles within the information transmission range. If the severity of the road surface event itself is low and the distance between the information transmission range and the place where the road surface event occurs is long, the road surface event has a low event severity for the target vehicles within the information transmission range.

And S32, generating and issuing driving route modification information to the target vehicle according to the severity of the event.

In the embodiment of the invention, the driving route modification information can be generated and issued to the target vehicle according to the severity of the event. The driving route modification information is used for guiding the target vehicle to have the road surface event and prompting the target vehicle of the severity of the event, so that the target vehicle is prompted to modify the driving route.

Thus, the vehicle can know the road surface event and the severity of the event through the driving route modification information before detecting that the surrounding environment of the vehicle has safety risks. Therefore, the vehicle can modify the driving route according to the severity of the road surface event, so that the vehicle can be ensured to run safely, and the safety of a driver is protected.

In an embodiment of the present invention, the driving route modification information is specifically used for guiding the target vehicle to perform at least one of the following driving route modification operations: modifying the current driving route according to the road event so that the vehicle can automatically avoid the road event through an automatic driving system; and sending a driving route modification prompt to the driver by adopting preset vehicle-mounted equipment so as to remind the driver to pay attention to modifying the driving route and avoid road surface events. The vehicle-mounted device may be a vehicle-mounted sound box, a vehicle interior atmosphere lamp, a vehicle-mounted display screen, and the like, which is not limited in this respect.

As an example of the present invention, if the road event is a vehicle collision accident and the target vehicle is close to the road event, the driving route modification information may guide the target vehicle through an automatic driving system to modify a current driving route of the vehicle so as to stop the vehicle from driving.

If the road event is a vehicle collision accident and the target vehicle has a certain distance from the place where the road event occurs, the driving route modification information may guide the target vehicle to modify the current driving route of the vehicle through an automatic driving system, so that the vehicle runs by changing lanes or roads.

If the road event is a vehicle collision accident and the target vehicle is far away from the road event, the driving route modification information can guide the target vehicle to modify the current driving route of the vehicle through an automatic driving system so that the vehicle can change the road for driving; or sending a driving route modification prompt to the driver, and resetting the driving route by the driver.

In one embodiment of the invention, the method further comprises:

s41, receiving the road event reference information sent by the vehicle;

in the embodiment of the invention, the road surface event reference information sent by the vehicle can be received. The road surface event information may be used to determine whether a road surface event has occurred around the location of the vehicle.

Specifically, the road surface event reference information may include at least one of driving system warning information, road surface event image information. The driving system warning information may be warning information generated when an automatic driving system of the vehicle detects that the vehicle is at risk, or when a risk is present in the vicinity of the vehicle. The road surface event image information is image information which is acquired by the vehicle through an image acquisition system and possibly comprises a road surface event.

And S42, determining whether the road surface event is monitored or not by using the road surface event reference information.

In the embodiment of the invention, the reference information of the road event can be adopted to determine whether the road event is monitored, so that the server can be adopted to monitor the driving safety of a plurality of vehicles.

In a specific implementation, the server may determine that a road surface event occurs at a location of the vehicle itself or that a road surface event occurs around the vehicle by using the driving system warning information. The server can also identify whether the road surface event exists in the road surface event image information, so that whether the road surface event exists in the periphery of the vehicle is known.

As an example of the present invention, in case of a collision accident of the vehicle, driving system warning information may be generated and transmitted to the server. Thus, the server may determine a road event that the vehicle has a collision accident using the driving system warning information.

As an example of the present invention, the vehicle acquires environment image information through an image acquisition device, and identifies a vehicle having a collision accident in the environment image information through an automatic driving system, so that the vehicle may generate driving system warning information and send the driving system warning information to the server. Thus, the server may determine a road event in which a collision accident occurs in front of the vehicle using the driving system warning information.

As an example of the present invention, the vehicle may acquire an image of an environment around the vehicle through the image acquisition device, generate road surface event image information, and transmit the road surface event image information to the server. The server may recognize whether a road surface event exists in the road surface event image information, thereby knowing whether a road surface event exists around the vehicle.

As an example of the present invention, the vehicle may also acquire an image of an environment around the vehicle through the image acquisition device, and preliminarily identify whether the image has a content that may be a road surface event, and in the case that the image has the content that may be the road surface event, generate road surface event image information using the image and send the road surface event image information to the server, so that the server may further identify the road surface event image information, determine whether the road surface event exists in the road surface event image information, and thus know whether the road surface event exists around the vehicle.

According to the method for adjusting the issued driving route, disclosed by the embodiment of the invention, the position reference information sent by a plurality of vehicles is received; determining vehicle path sequencing according to the position reference information of the vehicles; when a road surface event is monitored, determining a target vehicle according to the vehicle travel sequencing; generating and issuing driving route modification information to the target vehicle; the driving route modification information is used for prompting the target vehicle to modify the driving route. Therefore, the server can determine the vehicle path sequence, and when the road surface event is monitored, the server can send driving route modification information to a target vehicle which is possibly influenced by the road surface event in the vehicle path sequence so as to remind the target vehicle of the road surface event and guide the target vehicle to modify the driving route, so that the vehicle can know and avoid the road surface event before an automatic driving system detects that the surrounding environment of the vehicle has safety risk, the vehicle can be better ensured to run safely, and the safety of a driver is protected.

Referring to fig. 3, a flow chart of steps of an embodiment of a method for driving a vehicle, the method being applied to a vehicle that is in communication with a server, according to an embodiment of the present invention is shown.

In an embodiment of the invention, the vehicle may communicate with the server via a vehicle networking. Specifically, the internet of vehicles may include an in-vehicle network, an inter-vehicle network between vehicles, and an in-vehicle mobile internet, so that the vehicles may communicate with the server through the inter-vehicle network, the in-vehicle mobile internet, and the like.

The method may specifically comprise the steps of:

step 301, determining position reference information and sending the position reference information to the server in the vehicle running process;

in the embodiment of the invention, in the running process of the vehicle, the vehicle can acquire the position reference information which can be used for determining the position of the vehicle, and the position reference information is sent to the server through the internet of vehicles, so that the server can know the position of the vehicle based on the position reference information.

The position reference information may be information for determining a position of the vehicle itself. As an alternative embodiment of the present invention, the position reference information may be positioning information, an image of an environment around the vehicle, information of a proximity reference object input by the user, and the like, which is not limited by the present invention.

In a specific implementation, in the running process of the vehicle, the vehicle may determine the position reference information in real time and send the position reference information to the server, so that the server may obtain the real-time position of the vehicle based on the position reference information sent by the vehicle.

Step 302, receiving driving route modification information sent by the server; the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path sequence is determined according to the position reference information of the plurality of vehicles;

in the embodiment of the present invention, the vehicle may receive driving route modification information sent by the server for guiding the vehicle to modify the driving route, so that the vehicle may know that a road event affecting safe driving of the vehicle may occur in a range around the vehicle or on the driving route of the vehicle, and guide the target vehicle to modify the driving route to avoid the road event.

In the embodiment of the invention, the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path ranking is determined according to the position reference information of the plurality of vehicles.

In a specific implementation, the server may obtain the position reference information sent by the plurality of vehicles, so that the server may know the positions of the plurality of vehicles. Thereafter, a vehicle path rank may be determined based on the position reference information of the plurality of vehicles. When a road surface event is monitored, determining a target vehicle needing prompting according to the vehicle travel path sequence, and sending driving route modification information to the target vehicle. Therefore, the vehicle can acquire the driving route modification information sent by the server, so that the vehicle can learn the road surface event which is difficult to learn in real time by adopting the automatic driving system based on the driving route modification information and modify the driving route.

And step 303, modifying the driving route by adopting the driving route modification information.

In an embodiment of the present invention, the vehicle may modify the driving route using the driving route modification information. Therefore, before the automatic driving system detects that the safety risk exists in the surrounding environment of the vehicle through the image acquisition device, the sensor and other devices, the driving route modification information is adopted to modify the corresponding driving route, the safe driving of the vehicle is better ensured, and the safety of a driver is protected.

The specific manner of modifying the driving route may be to modify the current driving route according to the road event, send a driving route modification prompt to the driver, and the like, which is not limited in the present invention.

In a specific implementation, the vehicle may determine a specific situation of a road surface event and a distance between a location where the road surface event occurs and the vehicle using the driving route modification information to determine a corresponding modified driving route operation.

As an example of the invention, the road surface event is the occurrence of severe water accumulation on the road surface, and the distance between the location where the road surface event occurs and the vehicle is short. Because the severity of the road event is low and the distance is short, the vehicle is difficult to avoid the location of the road event, and a route modification prompt can be sent to the driver to remind the driver to modify the driving route.

As another example of the invention, the road surface event may be closed for a vehicle on a portion of a road, and the location where the road surface event occurs is a relatively large distance from the vehicle. And the vehicle can avoid the place of the road surface event due to the long distance, and the driving route can be modified by an automatic driving system so that the vehicle can avoid the place of the road surface event.

As another example of the present invention, the road surface event may be a collision accident of a vehicle, and the distance between the vehicle and the location where the road surface event occurs is short. Due to the fact that the severity of the road surface event is high, and due to the fact that the distance is short, the driving route can be modified through the automatic driving system, the vehicle stops driving or decelerates to drive, and rear-end collision accidents are avoided.

By the vehicle driving method, the driving route modification information sent by the server is received; the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path sequence is determined according to the position reference information of the plurality of vehicles; and modifying the driving route by adopting the driving route modification information. Therefore, before the automatic driving system detects that the safety risk exists in the surrounding environment of the vehicle through the image acquisition device, the sensor and other devices, the driving route modification information is adopted to modify the driving route, the safe driving of the vehicle is better ensured, and the safety of a driver is protected.

Referring to fig. 4, a flow chart of steps of another embodiment of a method of vehicle travel of the present invention is shown, applied to a vehicle in communication with a server.

the step of determining and transmitting the position reference information to the server during the vehicle driving process includes:

and S11, acquiring positioning information by using the positioning device in the running process of the vehicle, and sending the positioning information to the server.

In the embodiment of the invention, the vehicle can acquire the positioning information of the vehicle through the positioning device and send the positioning information to the server in the driving process, so that the server can know the real-time position of the vehicle.

The positioning device can be used for acquiring the position of the vehicle in a preset map so as to obtain the positioning information. Specifically, the Positioning device may obtain the position of the vehicle in the preset map through at least one of Positioning manners such as GPS (Global Positioning System), bluetooth Positioning, RFID (Radio Frequency IDentification), radar Positioning, laser Positioning, base station Positioning, and WiFi Positioning.

In one embodiment of the invention, the vehicle is provided with an image acquisition device, and the position reference information comprises environment image information;

and S21, acquiring environmental image information within a preset image pickup range by using the image acquisition device, and sending the environmental image information to the server.

In the embodiment of the invention, in the running process of the vehicle, the image acquisition device can be further adopted to acquire the environment image information in the preset camera shooting range around the vehicle and send the environment image information to the server, so that the server can know the environment around the vehicle according to the environment image information and determine the position of the vehicle.

In a specific implementation, the vehicle may be provided with at least one image capturing device for capturing an environment surrounding the vehicle, for example, a vehicle event recorder, a panoramic camera, a reversing camera, or the like. According to the position of the image acquisition device, the image acquisition device can acquire images in different shooting directions and different shooting angle ranges. And combining the images acquired by at least one image acquisition device to obtain the environmental image information in the preset camera shooting range around the vehicle. That is, the preset photographing range may be determined by a photographing direction and a photographing angle range of an image pickup device outside the vehicle.

As an example of the present invention, the vehicle may be provided with at least one image capturing device at a head portion and a tail portion of the vehicle, so that the image capturing devices may capture images of a front side and a rear side of the vehicle, respectively, and thereby environment image information with preset image capturing ranges of the front side and the rear side of the vehicle may be obtained.

As an example of the present invention, the vehicle may be provided with at least one image capturing device respectively at a head portion, a tail portion, a left side, and a right side of the vehicle, so that the image capturing devices may respectively capture images of a front portion of the vehicle, a rear portion of the vehicle, a left side, and a right side of the vehicle, and combine the images of the front portion of the vehicle, the rear portion of the vehicle, the left side, and the right side of the vehicle to obtain environment image information in which a preset imaging range is a panoramic view of a periphery of the vehicle.

Thereafter, the environment image information may be transmitted to the server so that the server may determine the location of the vehicle using the environment image information. As an alternative embodiment of the present invention, determining the position of the vehicle may be performed according to vehicle characteristic information of a vehicle ahead, vehicle characteristic information of a vehicle behind, a road sign, a surrounding building, and the like, which are collected from the environment image information.

Optionally, the vehicle may also send the positioning information and the environment image information to the server at the same time, and then the server may further determine the location of the vehicle based on the positioning information and the environment image information.

As an alternative embodiment of the present invention, the server may determine the geographic range of the vehicle in the map based on the positioning information. Thereafter, a specific location of the vehicle in the geographic area may be further determined based on the environment image information.

Step 402, receiving driving route modification information sent by the server; the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path sequence is determined according to the position reference information of the plurality of vehicles;

in the embodiment of the present invention, the vehicle may receive driving route modification information for guiding the vehicle to modify the driving route, which is sent by the server, so that the vehicle may know that a road event affecting safe driving of the vehicle may occur in a peripheral area of the vehicle or on the driving route of the vehicle, and guide the target vehicle to modify the driving route so as to avoid the road event

The road surface event may be an event that the vehicle collision accident occurs on the road, water logging affecting the safe driving of the vehicle occurs on the road surface, the road is blocked, the safe driving of the vehicle is possibly affected by the sealing of part of lanes or the sealing of all lanes of the road due to temporary construction, temporary accidents and the like, and the invention is not limited to this.

In the embodiment of the invention, the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path sequence is determined according to the position reference information of the plurality of vehicles

In one embodiment of the invention, the method further comprises:

s31, generating road surface event reference information and sending the road surface event reference information to the server, wherein the road surface event reference information comprises at least one of driving system alarm information and road surface event image information; the road surface event reference information is used for the server to monitor the road surface event.

In the embodiment of the invention, the vehicle can send the road surface event reference information to the server, so that the server can determine whether the road surface event happens around the position of the vehicle by adopting the road surface event reference information, thereby realizing the monitoring of the road surface event.

Wherein the road surface event reference information may include at least one of driving system warning information, road surface event image information.

The driving system warning information may be warning information generated when an automatic driving system of the vehicle detects that the vehicle is at risk, or when a risk is present in the vicinity of the vehicle. For example, in the case where the vehicle has a collision accident, driving system warning information may be generated and transmitted to the server so that the server may know that the vehicle has a collision accident. For another example, the vehicle acquires environment image information through an image acquisition device, and identifies a vehicle with a collision accident in the environment image information through an automatic driving system, so that the vehicle can generate driving system alarm information and send the driving system alarm information to the server, and the server can know the collision accident in front of the vehicle.

The road surface event image information may be image information of a road surface event possibly contained, which is acquired by the vehicle through an image acquisition system. In a specific implementation, the vehicle may acquire an image of an environment surrounding the vehicle through the image acquisition device, generate road surface event image information, and send the road surface event image information to the server. The server may recognize whether a road surface event exists in the road surface event image information, thereby knowing whether a road surface event exists around the vehicle. The vehicle can also acquire an image of the environment around the vehicle through the image acquisition device, preliminarily identify whether the image has the content which is possibly a road surface event, and generate road surface event image information by using the image and send the road surface event image information to the server under the condition that the image has the content which is possibly the road surface event, so that the server can further identify the road surface event image information, determine whether the road surface event exists in the road surface event image information, and know whether the road surface event exists around the vehicle.

As an example of the present invention, the vehicle may acquire an image of an environment around the vehicle by the image acquisition device, generate road surface event image information, and transmit the road surface event image information to the server. Therefore, the server can identify whether the road surface event exists in the road surface event image information or not, and identify that the road surface in front of the vehicle has the phenomenon of serious water accumulation in the road surface event image information. The server may determine that there is a road surface event with severe water accumulation around the vehicle.

As another example of the present invention, the vehicle may acquire an image of an environment around the vehicle through the image acquisition device, and preliminarily identify whether the image has a content that may be a road surface event, and if the vehicle identifies that a road surface in front of the vehicle has a serious water accumulation phenomenon, the vehicle may generate road surface event image information using the image and send the road surface event image information to the server. The server may further determine that there is a severe water accumulation phenomenon in the road surface event image information. The server may determine that there is a road surface event with severe water accumulation around the vehicle.

Step 403, using the driving route modification information, performing at least one operation as follows: and modifying the current driving route according to the road surface event and sending a driving route modification prompt to the driver.

As an example of the present invention, if the road surface event is a vehicle collision accident occurring in front, and the distance between the location of the road surface event and the vehicle is relatively short, 10 meters ahead of the vehicle. At this time, the road event may relatively seriously affect the safe driving of the vehicle, and the vehicle may modify the driving route through the automatic driving system to stop the vehicle from driving or decelerate the vehicle, so that the rear-end collision of the vehicle may be better avoided before the automatic driving system detects the risk of vehicle collision.

As another example of the present invention, if the road surface event is a vehicle collision accident occurring in front of the vehicle, and the distance between the location of the road surface event and the vehicle is relatively long, it is 100 meters ahead of the vehicle. At this time, the road event can slightly affect the safe driving of the vehicle, and the vehicle can modify the driving route through an automatic driving system so that the vehicle can drive by changing lanes. Or the vehicle can play voice prompt information by controlling a preset loudspeaker, display text prompt information in a preset display screen, control a preset atmosphere lamp to execute light prompt operation and the like, remind a driver of vehicle collision accidents in front of the vehicle, and advise the driver to modify a driving route. Therefore, the automatic driving system can be assisted, and the rear-end collision of the vehicle can be better avoided before the collision risk of the vehicle is detected.

As another example of the present invention, if the road surface event is a vehicle collision accident occurring on the current navigation route of the vehicle, and the distance between the location of the road surface event and the vehicle is long, the vehicle needs to travel a long distance before reaching the location of the road surface event. At the moment, the road event can slightly influence the safe driving of the vehicle, then the vehicle can play voice prompt information by controlling a preset loudspeaker, display text prompt information in a preset display screen, control a preset atmosphere lamp to execute light prompt operation and other modes, remind a driver of vehicle collision accidents on a navigation route, possibly cause road blockage, and advise the driver to modify the driving route. Alternatively, the vehicle may modify the driving route by an automatic driving system so that the vehicle may avoid the place of the road event. So that the vehicle can run on the road more safely and smoothly.

By the vehicle driving method, the driving route modification information sent by the server is received; the driving route modification information is a message which is generated by the server when a road surface event is monitored and is transmitted to a target vehicle, and the target vehicle is sequenced by the server according to the vehicle path and is determined from the plurality of vehicles; the vehicle path sequence is determined according to the position reference information of the plurality of vehicles; using the driving route modification information, performing at least one operation as follows: and modifying the current driving route according to the road surface event and sending a driving route modification prompt to the driver. Therefore, before the automatic driving system detects that the safety risk exists in the surrounding environment of the vehicle through the image acquisition device, the sensor and other devices, the driving route modification information is adopted to modify the driving route, the safe driving of the vehicle is better ensured, and the safety of a driver is protected.
