[0067] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0068] One of the core concepts of an embodiment of the present invention is to obtain road topology relationship information and guide line position information of the merging section and position information of the target vehicle in the merging section in a ramp merging scenario; determine the driving intention of the target vehicle based on the road topology relationship information, guide line position information and the position information of the target vehicle; and control the driving of the current vehicle based on the driving intention of the target vehicle; by integrating the road topology relationship information, guide line position information and the position information of the target vehicle, the system can more accurately judge the driving intention of the target vehicle and enhance the reliability and robustness of the system; the present invention can control the driving of the current vehicle based on the driving intention of the target vehicle, and the current vehicle can intelligently adjust the driving speed and path to avoid unnecessary deceleration or parking, thereby improving overall traffic efficiency and ensuring driving safety and comfort.

[0069] Reference Figure 1 , shows a flow chart of the steps of a vehicle control method provided by an embodiment of the present invention, including:

[0070] Step 101, in the case of a ramp merging scene, obtaining road topology relationship information and guide line position information of the merging section and position information of the target vehicle in the merging section.

[0071] In an embodiment of the present invention, the road topology relationship information describes the structure and connection relationship of the road, including the number of lanes, lane width, lane direction, intersections, ramp entrances and exits, etc.; the road topology relationship can be obtained through high-precision maps, sensors, and vehicle networks.

[0072] Current vehicles can use high-precision maps (HD Maps), which contain detailed road topology information such as lane lines, road boundaries, intersections, ramp entrances and exits, etc.

[0073] Vehicle-mounted sensors (such as lidar, cameras, millimeter-wave radar) can be used to perceive the road environment in real time, identify lane lines, road boundaries, traffic signs, etc., and build real-time road topology relationships.

[0074] Vehicle-to-everything (V2X) technology can be used to obtain road topology information from infrastructure or other vehicles to enhance perception capabilities.

[0075] The specific technology used to obtain road topology information is not limited here.

[0076] The guide line position information is a sign line used to guide vehicles to drive correctly when merging on ramps. Obtaining its position information helps vehicles accurately determine the timing and path of merging. The guide line position information can be obtained through high-precision maps, vehicle-mounted cameras, and laser radars.

[0077] The location information of the target vehicle can be obtained through the on-board sensors of the current vehicle, the Internet of Vehicles or high-precision maps. Specifically, on-board sensors: through on-board sensors (such as cameras, lidar, millimeter-wave radar) to perceive the position, speed and direction of surrounding vehicles in real time; V2X communication: through the Internet of Vehicles (V2X) technology, the target vehicle’s location, speed and driving intention information is obtained from the target vehicle or other vehicles; high-precision maps: combine high-precision maps and real-time perception data to infer the target vehicle’s location and driving path.

[0078] Step 102, determining the driving intention of the target vehicle according to the road topology relationship information, the guide line position information and the position information of the target vehicle.

[0079] In an embodiment of the present invention, after obtaining road topology relationship information, guide line position information and target vehicle position information, the vehicle's driving type can be determined based on the road topology relationship information, guide line position information and target vehicle position information, and then the target vehicle's driving intention can be determined based on the target vehicle's driving type.

[0080] In one example, assume that the current vehicle (vehicle A) is traveling on a ramp and is about to merge into the main road. If the target vehicle location information is that the target vehicle B is located in the right lane of the main road, 100 meters away from the merging point; the road topology relationship information is that the main road is a two-way four-lane road, the ramp is a one-way single lane, and the merging point between the ramp and the main road is located in the right lane of the main road; the guide line location information is: the guide line extends from the ramp to the right lane of the main road, and the shape is a dotted line; based on this information, it can be determined that the target vehicle B is going straight, and further, if the target vehicle B intends to continue going straight and is far away from the merging point, vehicle A can accelerate appropriately and merge safely into the main road; if the target vehicle B intends to continue going straight and is close to the merging point, vehicle A should maintain an appropriate distance and wait for the right time to merge into the main road.

[0081] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and target vehicle position information, including: when the target vehicle is determined to merge into the main road from the ramp based on the road topology relationship information, guide line position information and target vehicle position information, judging whether the map of the current vehicle covers the ramp where the target vehicle is located; if the map of the current vehicle covers the ramp where the target vehicle is located, determining that the driving intention of the target vehicle is a cutting-in intention; if the map of the current vehicle does not cover the ramp where the target vehicle is located, determining that the driving intention of the target vehicle is a merging intention.

[0082] In the embodiment of the present invention, Figure 2A schematic diagram of a vehicle merging of the present invention is shown. Assuming that the current vehicle (vehicle A) is traveling on the main road, the road topology relationship information is as follows: the main road is a two-way six-lane road (only a one-way three-lane road is shown in the figure), the ramp is a one-way two-lane road, and the merging point between the ramp and the main road is located in the right lane of the main road; the guide line position information: the guide line extends from the ramp to the right lane of the main road, and the shape is a dotted line; the target vehicle position information: the target vehicle 1 is located on the ramp, 50 meters away from the merging point, and facing the main road; it can be determined that the target vehicle 1 merges from the ramp Entering the main road, at this time, the map data of the current vehicle (vehicle A) can be judged to confirm whether it contains the ramp information where the target vehicle (vehicle 1) is located. If the map of the current vehicle covers the ramp where the target vehicle is located, it can be determined that the driving intention of the target vehicle B is an intention to cut in; if the target vehicle 1 intends to cut into the main road and is far away from the merging point, vehicle A can accelerate appropriately and merge into the main road safely. If the target vehicle B intends to cut into the main road and is close to the merging point, vehicle A should maintain an appropriate distance and wait for the right time to merge into the main road.

[0083] If the current vehicle's map does not cover the ramp where the target vehicle is located, the specific driving path of the target vehicle B cannot be determined, so its driving intention is judged to be a merging intention; further, if the target vehicle 1 intends to merge into the main road, vehicle A should slow down appropriately to provide enough merging space for vehicle 1, and vehicle A should remain vigilant and be ready to respond to the merging behavior of vehicle B at any time.

[0084] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and target vehicle position information, including: when it is determined that the target vehicle is located on the main road based on the road topology relationship information, guide line position information and target vehicle position information, obtaining a first time required for the current vehicle to reach the confluence point and a second time required for the target vehicle to reach the confluence point; determining whether the time difference between the first time and the second time is less than a preset value; if the time difference is less than the preset value, determining that the driving intention of the target vehicle is a merging intention.

[0085] In the embodiment of the present invention, Figure 3 , shows another schematic diagram of vehicle merging of the present invention, assuming that the current vehicle (vehicle A) is traveling on the ramp, preparing to merge into the main road, 100 meters away from the merging point, at a speed of 40km / h, and heading towards the main road.

[0086] Road topology information: The main road is a six-lane bidirectional road, the ramp is a three-lane unidirectional road, and the merging point between the ramp and the main road is located in the right lane of the main road.

[0087] Guide line location information: The guide line extends from the ramp to the right lane of the main road and is in the form of a dotted line;

[0088] Location information of the target vehicle: Target vehicle 2 is located in the right lane of the main road, 200 meters away from the merging point, with a speed of 60 km / h and a straight direction.

[0089] First time: 0.1 km / 40 km / h = 0.0025 hours = 9 seconds;

[0090] Second time: 0.2 km / 60 km / h = 0.00333 hours = 12 seconds;

[0091] Time difference: second time - first time = 12 seconds - 9 seconds = 3 seconds, assuming the preset value is 5 seconds.

[0092] The time difference of 3 seconds is less than the preset value of 5 seconds, and it is determined that the driving intention of the target vehicle 2 is a merging intention. If the target vehicle 2 intends to merge into the main road, vehicle A should slow down appropriately to provide sufficient merging space for vehicle 2.

[0093] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and the position information of the target vehicle, including: when it is determined that the target vehicle is traveling on a ramp and in an adjacent lane of the current vehicle based on the road topology relationship information, guide line position information and the position information of the target vehicle, the front direction and lateral speed of the target vehicle are obtained; based on the front direction and lateral speed of the target vehicle, it is determined whether the target vehicle is approaching the current vehicle; if the target vehicle is approaching the current vehicle, it is determined that the driving intention of the target vehicle is a cutting-in intention.

[0094] In the embodiment of the present invention, Figure 3 Assume that the current vehicle (vehicle A) is traveling on the ramp and is about to merge into the main road;

[0095] Road topology information: The main road is a six-lane bidirectional road, the ramp is a three-lane unidirectional road, and the merging point between the ramp and the main road is located in the right lane of the main road.

[0096] Guide line location information: The guide line extends from the ramp to the right lane of the main road and is in the shape of a dotted line.

[0097] Target vehicle location information: Target vehicle 3 is located in the adjacent lane of the ramp, 50 meters away from vehicle A, and has a speed of 40 km / h.

[0098] At this time, it can be determined that the target vehicle 3 is traveling on the ramp and in the adjacent lane of the current vehicle, and it can be further obtained that the front direction of the vehicle is 30 degrees (towards the lane where vehicle A is located); since the front direction of the target vehicle 3 is 30 degrees (towards the lane where vehicle A is located) and the lateral driving speed is 10km / h, condition 1 is satisfied: the front of the target vehicle is facing the lane where the current vehicle is located, and condition 2: the lateral driving speed of the target vehicle is greater than 0, indicating that the target vehicle 3 is approaching the current vehicle A. Since the target vehicle 3 is approaching the current vehicle A, it is determined that the driving intention of the target vehicle 3 is an intention to cut in. At this time, vehicle A should slow down appropriately to provide sufficient cutting-in space for vehicle 3.

[0099] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and target vehicle position information, including: when the target vehicle is determined to enter the ramp from the main road based on the road topology relationship information, guide line position information and target vehicle position information, the front direction and lateral speed of the target vehicle are obtained; based on the front direction and lateral speed of the target vehicle, it is determined whether the target vehicle is approaching the current vehicle; if the target vehicle is approaching the current vehicle, the driving intention of the target vehicle is determined to be a cutting-in intention.

[0100] In the embodiment of the present invention, Figure 4 , shows another schematic diagram of vehicle convergence of the present invention, assuming that the current vehicle (vehicle A) is driving in the right lane of the main road, 200 meters away from the ramp entrance, at a speed of 60km / h, and in a straight direction. Prepare to judge the driving intention of the target vehicle (vehicle 4), road topology relationship information: the main road is a two-way six-lane road, the ramp is a one-way two-lane road, and the convergence point between the ramp and the main road is located in the right lane of the main road;

[0101] Guide line location information: The guide line extends from the main road to the ramp and is in the shape of a dotted line.

[0102] Target vehicle location information: Target vehicle 4 is located in the left lane of the main road, 100 meters away from the ramp entrance, with a speed of 50 km / h.

[0103] According to the road topology information, the guide line position information and the target vehicle's position information, it can be determined that the target vehicle is driving into the ramp from the main road. At this time, the front direction of the vehicle can be obtained to be 45 degrees (towards the ramp) and the lateral speed is 15km / h. At this time, the front direction of the target vehicle 4 is 45 degrees (towards the ramp) and the lateral speed is 15km / h, which meets condition 1: the front of the target vehicle is facing the lane where the current vehicle is located, and condition 2: the lateral speed of the target vehicle is greater than 0, indicating that the target vehicle 4 is approaching the ramp. Since the target vehicle 4 is approaching the ramp, it is determined that the driving intention of the target vehicle 4 is an intention to cut in.

[0104] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and the position information of the target vehicle, including: when it is determined that the target vehicle and the current vehicle are traveling in the same lane line based on the road topology relationship information, guide line position information and the position information of the target vehicle, the driving acceleration of the target vehicle is obtained; and it is determined whether the driving acceleration is greater than a preset value. If the driving acceleration is greater than the preset value, it is determined that the driving intention of the target vehicle is an accelerating driving intention.

[0105] In the embodiment of the present invention, Figure 4 ,Assume that the current vehicle (vehicle A) is traveling on the main road, 5,50 meters away from the target vehicle, at a speed of 60km / h, and in a straight direction. The road topology information is: the main road is a two-way six-lane road, the ramp is a one-way two-lane road, and the merging point between the ramp and the main road is located in the right lane of the main road;

[0106] Guide line location information: The guide line is located in the right lane of the main road and is in the shape of a dotted line. Target vehicle location information: Target vehicle 5 is located in the same lane of the main road, 50 meters away from vehicle A, with a speed of 60 km / h and a driving acceleration of 2 m / s 2 .

[0107] Assume the preset value is 1.5m / s 2 , Judgment result: The driving acceleration of the target vehicle 5 is 2m / s 2 Greater than the preset value 1.5m / s 2 .

[0108] Since the driving acceleration of the target vehicle 5 is greater than the preset value, it is determined that the driving intention of the target vehicle 5 is an accelerating driving intention. If the target vehicle 5 intends to accelerate, vehicle A should maintain an appropriate distance to avoid collision with vehicle 5.

[0109] In one embodiment of the present invention, the driving intention of the target vehicle is determined based on road topology relationship information, guide line position information and target vehicle position information, including: when it is determined that the target vehicle has entered a ramp based on road topology relationship information, guide line position information and target vehicle position information, judging whether there is a ramp at a preset distance in front of the target vehicle; if there is no ramp at a preset distance in front of the target vehicle, determining that the driving intention of the target vehicle is to drive on the ramp.

[0110] In the embodiment of the present invention, Figure 4, assuming that the current vehicle (vehicle A) is driving on the main road, and is preparing to judge the driving intention of the target vehicle (vehicle 6), the road topology relationship information is obtained at this time: the main road is a two-way six-lane road, the ramp is a one-way two-lane road, and the merging point between the ramp and the main road is located in the right lane of the main road. Guide line position information: The guide line extends from the main road to the ramp, and the shape is a dotted line.

[0111] Target vehicle location information: Target vehicle 6 has entered the ramp, is 50 meters away from the ramp entrance, and is at a speed of 40 km / h.

[0112] Assuming that the preset distance is 100 meters, it is determined that there is no ramp within 100 meters in front of the target vehicle 6. At this time, since there is no ramp within 100 meters in front of the target vehicle 6, it is determined that the driving intention of the target vehicle 6 is to drive on the ramp. If the target vehicle 6 intends to drive on the ramp, vehicle A should constrain the predicted trajectory of the target vehicle 6 to prevent the trajectory from jumping to the main road.
