Description

Technical Field

[0001] The present application relates to the field of intelligent driving technology, and in particular to a vehicle control method and related devices. Background Art

[0002] A road intersection (also known as a road junction) is the intersection of two or more roads. Its shapes include, but are not limited to, T-shaped, Y-shaped, cross-shaped, X-shaped, and circular. It is a necessary place for vehicles and pedestrians to converge, turn, and evacuate. Traffic lights (also known as traffic lights) are usually installed at road intersections. Traffic lights are controlled by traffic signal controllers to guide vehicles and pedestrians through safe and orderly passage. They are an important tool for strengthening road traffic management, reducing traffic accidents, improving road efficiency, and improving traffic conditions.

[0003] In the current assisted driving technology solutions, for systems that use global navigation recommendations, when a vehicle passes through an intersection, the vehicle's driving behavior at the intersection is mainly decided based on navigation path planning.

[0004] However, vehicles in lane centering control (LCC) scenarios do not use the system recommended by the global navigation and are unable to make decisions about the vehicle's driving behavior at intersections based on navigation path planning, which may lead to driving safety risks. Summary of the Invention

[0005] The embodiments of the present application provide a vehicle control method and related devices, which can determine the vehicle's driving behavior at intersections and reduce driving safety risks for vehicles that do not use the global navigation recommendation system in the LCC scenario.

[0006] In a first aspect, embodiments of the present application provide a vehicle control method for a vehicle in a lane centering (LCC) scenario. The vehicle control method comprises: obtaining driving direction indication information for the lane in which the vehicle is located, and generating a first driving decision based on the driving direction indication information. The first driving decision is used to control the driving behavior of the vehicle at a first intersection, where the first intersection is the intersection in front of the vehicle.

[0007] In the embodiment of the present application, for vehicles in LCC scenarios that do not use the global navigation recommendation system, it is impossible to make driving decisions at intersections based on navigation route planning, and thus the lane centering function for non-straight intersections is not supported. However, in the embodiment of the present application, corresponding driving decisions are generated based on the driving direction indication information of the vehicle's lane, and the vehicle's driving behavior at intersections is controlled, supporting the lane centering function for non-straight intersections. By making correct driving decisions, driving safety risks can be reduced.

[0008] Alternatively, the driving direction information for the lane in which the vehicle is located can be understood as broadly static lane information perceived by the vehicle, including, but not limited to, lane markings, lane guide arrows, lane direction signage, and so on, which are not listed in detail in the present embodiment. By combining multiple types of perceived lane static information, the driving direction information corresponding to the lane in which the vehicle is located can be more accurately determined, thereby generating correct driving decisions and reducing driving safety risks.

[0009] In a possible implementation of the first aspect, the vehicle control method further includes: obtaining traffic light information at a first intersection. Generating a first driving decision based on the driving direction indication information includes: determining the type of lane in which the vehicle is located based on the driving direction indication information; if the vehicle's lane is a composite lane including left and right turns, determining first traffic light information at the first intersection based on the color state and / or countdown information in the traffic light information; and generating a first driving decision based on the first traffic light information, the first driving decision being used to control the vehicle to pass through the first intersection in the driving direction corresponding to the first traffic light information or to brake before the first intersection.

[0010] In an embodiment of the present application, when it is determined that the lane where the vehicle is located is a composite lane including left turns and right turns, the scenario can be considered as a scenario with unknown driving intention. At this time, the first traffic light information of the first intersection is determined based on the color status and / or countdown information of the traffic light. The first traffic light can be understood as a conservative light. For example, when the traffic light corresponding to the left-turn lane is a circular red color and the traffic light corresponding to the right-turn lane is a circular green color, the circular red traffic light corresponding to the left-turn lane is determined as the first traffic light information of the first intersection, and a first driving decision is generated based on the first traffic light information. The vehicle is controlled to brake before the first intersection according to the first traffic light information and wait for the circular red traffic light to turn green before turning left. For another example, when the traffic light corresponding to the left-turn lane is green with a countdown of 5 seconds, and the traffic light corresponding to the right-turn lane is green with a countdown of 20 seconds, the traffic light corresponding to the right-turn lane with a countdown of 20 seconds is determined as the first traffic light information of the first intersection, that is, the traffic light with the longest allowed passage time is selected as the first traffic light information, and a first driving decision is generated based on the first traffic light information, controlling the vehicle to turn right through the first intersection according to the driving direction corresponding to the first traffic light information. Through the embodiments of the present application, when the turning intention is unknown, it is possible to conservatively select the traffic light, comply with the traffic rules set at the first intersection, and reduce the safety risk of running a red light.

[0011] In a possible implementation of the first aspect, the generating of the first driving decision based on the driving direction indication information includes: determining the type of lane in which the vehicle is located based on the driving direction indication information; when the lane in which the vehicle is located is a one-way turn lane, generating a first driving decision for controlling the vehicle to drive in the driving direction indicated by the one-way turn lane at the first intersection; or, when the lane in which the vehicle is located is a composite lane including straight driving, generating a first driving decision for controlling the vehicle to drive straight at the first intersection; or, when the lane in which the vehicle is located is a composite lane including left turns and U-turns, generating a first driving decision for controlling the vehicle to turn left at the first intersection; or, when the lane in which the vehicle is located does not include a driving direction indication, generating a first driving decision for controlling the vehicle to drive straight at the first intersection.

[0012] In an embodiment of the present application, when the first driving decision is generated only based on the driving direction indication information, the type of lane in which the vehicle is located is first determined based on the driving direction indication information, and then the corresponding first driving decision is generated based on the type of lane in which the vehicle is located. The vehicle is controlled to drive according to the type of lane in which the vehicle is located at the first intersection. By deciding the correct driving behavior, the problem of driving safety risks can be reduced.

[0013] In a possible implementation of the first aspect, the above-mentioned vehicle control method also includes: obtaining the driver's driving steering intention information; the above-mentioned generating a first driving decision based on the driving direction indication information includes: generating a first driving decision based on the driving direction indication information and the driving steering intention information.

[0014] In the implementation mode of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, corresponding driving decisions are generated based on the driving direction indication information of the vehicle's lane and the driver's driving steering intention information to control the vehicle's driving behavior at the intersection, and support the lane centering function for non-straight-across intersections. By deciding the correct driving behavior, the problem of driving safety risks can be reduced.

[0015] Optionally, the driver's steering intention information can be understood as a series of actions the driver takes regarding straight or non-straight driving when facing the intersection ahead, including, but not limited to, lever information, steering wheel information, etc., which are not listed one by one in the embodiments of this application. By integrating the driving direction indication information of the perceived lane and the driver's steering intention information, the vehicle's corresponding driving intention can be more accurately determined, thereby generating correct driving decisions and reducing driving safety risks.

[0016] In a possible implementation of the first aspect, the generating of the first driving decision based on the driving direction indication information and the driving steering intention information includes: generating the first driving decision based on the driving direction indication information and the driving steering intention information when the vehicle meets the turning conditions.

[0017] In an embodiment of the present application, when a corresponding first driving decision is generated based on the driving direction indication information of the lane in which the vehicle is located and the driver's driving steering intention information, the driver's driving steering intention information can be understood in multiple ways. On the one hand, when the vehicle meets the turning conditions, the driver's driving steering intention information when facing the intersection ahead can be understood as turning. On the other hand, when the vehicle does not meet the turning conditions, the driver's driving steering intention information when facing the intersection ahead can be understood as changing lanes. When the driver's driving steering intention information is understood as turning, in other words, when the vehicle meets the turning conditions, the first driving decision is generated based on the driving direction indication information and the driving steering intention information. When the driver's driving steering intention information is understood as changing lanes, in other words, when the vehicle does not meet the turning conditions, the first driving decision is generated based on the driving direction indication information.

[0018] Through the embodiments of the present application, the driving steering intention information is understood as changing lanes or turning, and corresponding different methods are adopted to generate driving decisions, which can improve the accuracy of driving decisions and ensure the safety of the vehicle at the first intersection.

[0019] In a possible implementation of the first aspect, the above-mentioned turning condition includes at least one of the following: the distance between the vehicle and the first intersection is less than a first threshold, and the steering operation force corresponding to the driving steering intention information is greater than a second threshold.

[0020] In the embodiments of the present application, when the distance between the vehicle and the first intersection is less than a first threshold, the vehicle is deemed to have the distance and time to approach the first intersection and to execute a turn, thus meeting the turning condition. It is understood that the first threshold is not a fixed value and can be adjusted based on different application scenarios. When the steering operation force corresponding to the driving steering intention information is greater than a second threshold, the steering intention can be considered significant, and the driving intention information is further deemed to be a turn, thus meeting the turning condition. It is understood that the steering operation force can refer to the steering lever force or the steering wheel force.

[0021] In a possible implementation of the first aspect, the above-mentioned generating a first driving decision based on the above-mentioned driving direction indication information and the driving steering intention information includes: determining the type of lane in which the vehicle is located according to the driving direction indication information; when the driving steering intention information indicates a right turn and the lane in which the vehicle is located is a lane that includes a right turn, generating a first driving decision for controlling the vehicle to turn right at the first intersection; or, when the driving steering intention information indicates a left turn and the lane in which the vehicle is located is a lane that includes a left turn, generating a first driving decision for controlling the vehicle to turn left at the first intersection; or, when the driving steering intention information indicates a left turn and the lane in which the vehicle is located is a lane that includes a U-turn but does not include a left turn, generating a first driving decision for controlling the vehicle to turn around at the first intersection.

[0022] In this embodiment of the present application, when the driver's steering intention information is acquired and the vehicle meets the steering conditions, the driving direction indication information and the steering intention information are combined to generate a first driving decision. For vehicles in LCC scenarios that do not utilize a global navigation recommendation system, the fusion of the lane-perceived driving direction indication information and the driver's steering intention information can more accurately determine the vehicle's corresponding driving intention, thereby generating a correct first driving decision, instructing the vehicle to follow the vehicle's corresponding driving intention at the first intersection and reducing driving safety risks.

[0023] In a possible implementation of the first aspect, the vehicle control method further includes: acquiring traffic light information at the first intersection; and generating a second driving decision based on the traffic light information at the first intersection and the first driving decision.

[0024] In an embodiment of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, a corresponding second driving decision is generated based on the first driving decision and the traffic light information at the first intersection to control the vehicle's driving behavior at the intersection. By deciding the correct driving behavior, the risk of running a red light can be reduced and the traffic rules set at the first intersection can be complied with.

[0025] Optionally, the traffic light information at the first intersection may include, but is not limited to, traffic light information set at the first intersection, for guiding vehicles and pedestrians to pass through the first intersection safely and orderly.

[0026] Through the embodiments of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, the fusion of the driving direction indication information of the perceived lane, the driver's driving steering intention information and the traffic light information at the first intersection can more accurately determine the vehicle's corresponding driving intention, generate a correct second driving decision that complies with traffic rules, control the vehicle to drive according to the vehicle's corresponding driving intention at the first intersection, and comply with the traffic rules set at the first intersection, thereby reducing the risk of running a red light.

[0027] In a possible implementation of the first aspect, the generating of the second driving decision based on the traffic light information at the first intersection and the first driving decision includes: when the first driving decision is non-straight driving, determining the second traffic light information at the first intersection corresponding to the first driving decision; generating the second driving decision based on the second traffic light information, the second driving decision being used to control the vehicle to pass through the first intersection in the driving direction corresponding to the first driving decision or to brake before the first intersection.

[0028] In an embodiment of the present application, when the generated first driving decision is a non-straight-ahead decision (e.g., a left turn, a right turn, or a U-turn), the second traffic light information at the first intersection corresponding to the first driving decision is determined, and the vehicle is controlled to pass through the first intersection in the driving direction corresponding to the first driving decision or to brake before the first intersection based on the second traffic light information. Through the embodiment of the present application, when the first driving decision is a non-straight-ahead decision, a correct second driving decision that complies with traffic rules can be generated, and the vehicle can be controlled to travel in the driving direction corresponding to the first driving decision at the first intersection and comply with the traffic rules set at the first intersection, thereby reducing the risk of running a red light.

[0029] In a possible implementation of the first aspect, the above-mentioned vehicle control method also includes: when the first driving decision is non-straight driving, generating a third driving decision, the third driving decision is also used to instruct the vehicle to output a takeover request, and the takeover request is used to request the driver to take over the vehicle at the first intersection.

[0030] In an embodiment of the present application, when the vehicle is instructed to go non-straight at the first intersection (for example, turn left, turn right, or make a U-turn), a third driving decision can also be generated accordingly, instructing the vehicle to output a takeover request, which is used to request the driver to take over the vehicle at the first intersection and complete the intersection turning operation by the driver.

[0031] In a possible implementation of the first aspect, the driving direction indication information includes lane guide arrow information and / or lane driving direction sign information.

[0032] In a possible implementation of the first aspect, the driving steering intention information includes steering lever information and / or steering wheel steering information.

[0072] In order to make the purpose, technical solutions and advantages of this application clearer, the embodiments of this application will be described below in conjunction with the drawings in the embodiments of this application.

[0073] The terms "first" and "second" in the specification, claims, and drawings of this application are used to distinguish different objects, not to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to the process, method, product, or device.

[0074] The “embodiment” mentioned herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It can be understood explicitly and implicitly by those skilled in the art that in the various embodiments of the present application, unless otherwise specified and there is a logical conflict, the terms and / or descriptions between the various embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their inherent logical relationship.

[0075] It should be understood that in the present application, "at least one (item)" refers to one or more, "more than one" refers to two or more, "at least two (items)" refers to two or three and more than three, and "and / or" is used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, "A and / or B" can mean: only A exists, only B exists, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b or c can mean: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, c can be single or multiple.

[0076] It should be noted that in this application, "indication" can include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0077] In this application, the information indicated by the indication information is referred to as the information to be indicated. In specific implementations, there are many ways to indicate the information to be indicated. For example, but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or an index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, where the other information is associated with the information to be indicated. Alternatively, only a portion of the information to be indicated can be indicated, while the rest of the information to be indicated is known or agreed upon in advance. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-specified) order of the various information, thereby reducing indication overhead to a certain extent. The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. The transmission period and / or transmission timing of these sub-information can be the same or different. The specific transmission method is not limited in this application. The transmission period and / or transmission timing of these sub-information can be pre-defined, for example, according to a protocol, or can be configured by the transmitting device sending configuration information to the receiving device.

[0078] It should be noted that in this application, "send" can be understood as "output" and "receive" can be understood as "input". "Send information to A", where "to A" only indicates the direction of information transmission, A is the destination, and does not limit "sending information to A" to direct transmission on the air interface. "Sending information to A" includes sending information directly to A, and also includes sending information indirectly to A through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, including receiving information directly from A, and also including receiving information indirectly from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0079] This application provides a vehicle control method and related devices for use in the field of intelligent driving technology, such as controlling a vehicle in an LCC scenario without a global navigation recommendation system. To more clearly describe the solution of this application, the following first introduces a vehicle and its possible application scenario.

[0080] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a vehicle system architecture provided in an embodiment of the present application is shown. Figure 2 A schematic diagram of a scenario in which a driver controls a vehicle provided in an embodiment of the present application.

[0081] like Figure 1 and Figure 2As shown, the vehicle 100 may include a power system 11 and a braking system 12, and optionally, may further include a sensor system 13, a computing device 14 or a peripheral device 15, etc. Among them:

[0082] The power system 11 provides power for the vehicle 100, and includes, for example, one or more of an engine, a power battery, etc. The power system 11 includes an accelerator, which includes an accelerator pedal. The accelerator pedal is usually configured to be movable under force. Figure 2 The driver can step on or release the accelerator pedal, so that the accelerator pedal opens or retracts a certain angle, so that the driving speed of the vehicle 100 is controlled.

[0083] The braking system 12 may represent a system for slowing down the vehicle 100 and may also be referred to as a brake system. It may include, but is not limited to, a brake controller, a retarder, or any other structural device for decelerating the vehicle. In some embodiments, the braking system 12 may utilize friction to slow the movement of the vehicle's tires, thereby reducing the vehicle's speed. The braking system 12 of some vehicles includes a brake pedal, which is typically also configured to be movable under force. For example, the driver can step on or release the brake pedal to control the speed of the vehicle 100.

[0084] The sensor system 13 may include several detection devices (or detection devices) that can measure information and convert the measured information into electrical signals or other required forms of information output according to certain rules. Figure 1 As shown, the sensor system 13 of the vehicle 100 includes one or more of the following detection devices: an image sensor 131, a voice system 132, a laser radar 133, a radar 134, a wheel speed sensor 135, a steering sensor 136, or a positioning system 137. The following is an exemplary introduction to some of these detection devices:

[0085] The image sensor 131 is used to capture images, such as images and videos. In some specific implementations, the camera device includes but is not limited to a driving recorder, a camera, a camera, or other elements for taking photos / photographs. Optionally, the image sensor 131 can be configured to capture images of the outside of the vehicle to obtain information about the surrounding environment of the vehicle. Alternatively, the image sensor 131 can be configured to capture images of the interior of the vehicle, such as images of the driver and the cockpit. Exemplarily, a driver monitor system (DMS) is deployed in the vehicle, and the DMS system includes the image sensor 131, such as Figure 2As shown, the image sensor 131 can be positioned toward the driver and, when enabled, can continuously capture images in real time in the direction of the driver. For another example, a cockpit monitoring system (CMS) is deployed in the vehicle to capture images within the cabin. Of course, in a specific implementation, the vehicle also includes multiple image sensors 131 to simultaneously capture images of both the interior and exterior of the vehicle.

[0086] The voice system 132 is used to collect sound information. For example, the voice system may include a microphone 153 or be connected to a microphone 153. In some embodiments, the voice system 132 also includes a speaker 152, which is used to emit sound. Furthermore, the voice system can interact with the user, for example, by receiving user input (such as collecting voice in the cabin) and / or inputting voice prompts to the user, thereby interacting with the user by voice. In some embodiments, the voice system 132 can be used to collect voice in the cabin.

[0087] The laser radar 133 and the radar 134 are devices that detect through electromagnetic waves (including light), which can obtain relevant information about the target in the object space by transmitting signals and receiving echoes, including one or more of the target's distance (or depth), angle, speed, reflectivity, color, etc. Figure 2 , the laser radar 133 can be set to face the outside of the vehicle to detect targets around the vehicle. In some solutions, the laser radar 133 and the radar 134 can be used to detect the surrounding environment information of the vehicle, such as static environment information, dynamic environment information, etc. around the vehicle.

[0088] The wheel speed sensor 135 is a sensor for detecting the rotational speed of the vehicle wheels and can obtain the vehicle wheel speed. Common wheel speed sensors 135 may include but are not limited to magnetoelectric wheel speed sensors and / or Hall-effect wheel speed sensors.

[0089] Steering sensor 136 , also known as a steering angle sensor, represents a system for detecting the steering angle of a vehicle. In practical applications, steering sensor 136 can be used to measure the steering angle of the vehicle's steering wheel, or to measure an electrical signal representing the steering angle of the vehicle's steering wheel. Alternatively, steering sensor 136 can also be used to measure the steering angle of the vehicle's tires, or to measure an electrical signal representing the steering angle of the vehicle's tires.

[0090] The positioning system 137 is a device for obtaining position information, which can be used to realize real-time positioning of the vehicle and provide the vehicle's geographical location information. The positioning system is, for example, the Global Positioning System (GPS) or the Beidou positioning and navigation system.

[0091] The peripheral device 15 may include several elements, such as the human-machine interaction (HMI) 151, speaker 152, microphone 153, etc. shown in the figure. Among them, HMI is a device connected to the input and / or output device to realize the information interaction between people and machines, including but not limited to displays (such as the vehicle's central control screen, streaming media rearview mirror, instrument panel, head up display (head up display, HUD), light field screen, or projector, etc.), touch screen, etc. In some schemes, speakers, microphones, etc. can also be regarded as HMI. Speaker 152, also known as a speaker, is used to convert audio electrical signals into sound signals. The vehicle listens to music or listens to hands-free calls through speaker 152. Microphone 153, also known as a microphone, is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user speaks close to microphone 153, and microphone 153 can input the sound signal into the microphone.

[0092] The computing device 14 is a device with computing and / or control capabilities, and may include one or more processors, which can be used to run programs or instructions corresponding to the programs to implement corresponding functions. Exemplarily, the computing device is a mobile data center (MDC) (or autonomous driving domain controller), a domain controller (DC), an electronic control unit (ECU), etc., where the DC is such as a motion domain controller (MDC), a vehicle domain controller (VDC), etc. In some solutions, the computing device 14 may not be set in the vehicle, for example, it may be set in the cloud, roadside equipment or data center.

[0093] As a possible implementation, computing device 14 can be combined with other components in the vehicle, such as one or more of the power system 11, braking system 12, and sensor system 13 in sensor system 13, to implement driving assistance functions. For example, computing device 14 can control the speed of vehicle 100 based on data collected by sensor system 13.

[0094] In some embodiments, the vehicle further includes a memory for providing storage space. For example, the memory may include a volatile memory, such as RAM. As another example, the memory may also include a non-volatile memory, such as read-only memory (ROM), flash memory, a hard disk drive (HDD), or a solid state drive (SSD). The memory may also include a combination of the above types of memory. Optionally, the memory may also store information such as road maps, driving routes, sensor data, etc.

[0095] It should be noted that the above Figure 1 This is merely a schematic diagram of a possible functional framework of vehicle 100. In actual applications, vehicle 100 may include more or fewer systems or components, and the present invention is not limited thereto. For example, vehicle 100 may also include a power supply or a communication system.

[0096] See also Figure 3 , Figure 3 A schematic diagram of a driving scenario provided in an embodiment of the present application.

[0097] like Figure 3 As shown, a scene of a vehicle 100 driving through a road intersection is shown, where a traffic light 200 is provided.

[0098] A road intersection (also known as a road junction) refers to the intersection of two or more roads. Its shapes include, but are not limited to, T-shaped, Y-shaped, cross-shaped, X-shaped, and circular. It is a necessary place for vehicles and pedestrians to converge, turn, and evacuate. Traffic lights (also known as traffic lights) are usually installed at road intersections. Traffic lights are controlled by traffic signal controllers to guide vehicles and pedestrians through safe and orderly passage. They are an important tool for strengthening road traffic management, reducing traffic accidents, improving road efficiency, and improving traffic conditions.

[0099] In the current assisted driving technology solutions, for systems that use global navigation recommendations, when a vehicle passes through an intersection, the vehicle's driving behavior at the intersection is mainly decided based on navigation path planning.

[0100] However, vehicles in the LCC scenario do not use the global navigation recommendation system and cannot make decisions on the vehicle's driving behavior at intersections based on navigation path planning, which may lead to driving safety risks.

[0101] In view of this, the present application provides a vehicle control system architecture and proposes a new vehicle control method based on the architecture. For the system in which the vehicle does not use the global navigation recommendation in the LCC scenario, the corresponding driving decision is generated according to the driving direction indication information of the lane in which the vehicle is located, and the driving behavior of the vehicle at the intersection is controlled. The lane centering function of non-straight-across intersections is supported. By deciding the correct driving behavior, the problem of driving safety risks can be reduced.

[0102] See also Figure 4 , Figure 4 A schematic diagram of the architecture of a possible vehicle control system provided in an embodiment of the present application.

[0103] like Figure 4 As shown, the architecture of the vehicle control system can be applied to the control of vehicles in LCC scenarios that do not use a global navigation recommendation system, and mainly involves three parts: a perception module 401, a vehicle driving intention judgment module 402, and a driving decision generation module 403.

[0104] Among them, the perception module 401, the vehicle driving intention judgment module 402, and the driving decision generation module 403 are connected through a network.

[0105] The perception module 401 can be used to perceive the driving direction indication information of the lane where the vehicle is located, the driver's driving steering intention information, and traffic light information. The driving direction indication information of the lane where the vehicle is located can be understood as the static information about the lane perceived by the vehicle in a broad sense, for example, including but not limited to: lane lines, lane guide arrow information, lane driving direction sign information, etc., which are not listed one by one in the embodiments of the present application. The driver's driving steering intention information can be understood as a series of straight or non-straight action responses made by the driver when facing the intersection ahead, for example, including but not limited to: lever information, steering wheel steering information, etc., which are not listed one by one in the embodiments of the present application. Traffic light information may include but is not limited to traffic light information set at the intersection, which is used to guide vehicles and pedestrians to pass through the intersection safely and orderly.

[0106] The vehicle's driving intention determination module 402 can be used to determine the vehicle's driving intention based on one or more of the driving direction indication information of the vehicle's lane, the driver's driving steering intention information, etc., obtained by the perception module 401. On the one hand, the vehicle's driving intention determination module 402 can determine the vehicle's driving intention based on the driving direction indication information of the vehicle's lane. On the other hand, the vehicle's driving intention determination module 402 can determine the vehicle's driving intention based on the driving direction indication information of the vehicle's lane and the driver's driving steering intention information. It is understood that if the vehicle's driving intention determination module 402 does not obtain the driver's driving steering intention information, the vehicle's driving intention is determined based on the driving direction indication information of the vehicle's lane; if the vehicle's driving intention determination module 402 obtains the driver's driving steering intention information, the vehicle's driving intention is determined based on the driving direction indication information of the vehicle's lane and the driver's driving steering intention information.

[0107] The driving decision generation module 403 can be configured to generate a driving decision based on one or more of the vehicle's driving intention determined by the driving intention determination module 402 and the traffic light information obtained by the perception module 401. The driving decision is used to control the vehicle to perform a corresponding driving behavior. In one aspect, the driving decision generation module 403 can generate a driving decision based on the vehicle's driving intention determined by the driving intention determination module 402. In another aspect, the driving decision generation module 403 can generate a driving decision based on the vehicle's driving intention determined by the driving intention determination module 402 and the traffic light information obtained by the perception module 401. It is understood that if there is no traffic light at the intersection, or if there is a traffic light but it is not functioning, the driving decision generation module 403 generates a driving decision based on the vehicle's driving intention determined by the driving intention determination module 402. If there is a traffic light at the intersection and it is functioning properly, the driving decision generation module 403 generates a driving decision based on the vehicle's driving intention determined by the driving intention determination module 402 and the traffic light information obtained by the perception module 401.

[0108] It is understandable that in the above Figure 4 In the vehicle control system shown, there are many possible deployment methods for the perception module 401, the vehicle driving intention judgment module 402, and the driving decision generation module 403, and this application does not impose any restrictions on this.

[0109] Exemplarily, the perception module 401, the vehicle driving intention judgment module 402, and the driving decision generation module 403 can be deployed on an intelligent driving vehicle and connected via a wired or wireless network.

[0110] Based on the above Figure 4 The vehicle control system architecture shown in the figure, this application also provides a new vehicle control method, which will be combined with Figures 5 to 10 This vehicle control method will be described.

[0111] See also Figure 5 , Figure 5 This is a flow chart of a vehicle control method provided in an embodiment of the present application. This vehicle control method is applied to the field of intelligent driving technology, such as controlling a vehicle in an LCC scenario without using a global navigation recommendation system. Specifically, this vehicle control method includes but is not limited to the following steps:

[0112] S501: The vehicle control device obtains driving direction indication information of the lane where the vehicle is located.

[0113] S502: The vehicle control device generates a first driving decision according to the driving direction indication information.

[0114] It is understood that the vehicle control device in the embodiments of the present application can be a device equipped with a processor / chip capable of executing computer-executable instructions, or a processor / chip capable of executing computer-executable instructions. Optionally, the vehicle control device can be an electronic device, or a processor / chip within an electronic device, configured to execute the vehicle control method in the embodiments of the present application, so as to implement a system for determining the vehicle's driving behavior at intersections when the vehicle does not use global navigation recommendations in LCC scenarios, thereby reducing driving safety risks.

[0115] Optionally, the architecture of the vehicle control device at this time can refer to the above Figure 4 The vehicle control system shown in FIG. 4 is a vehicle control system comprising a driving intention judgment module 402 and a driving decision generation module 403. In this case, the vehicle control device and the sensing device constitute a vehicle control system. Figure 4 The vehicle control system architecture shown in FIG. The sensing device is used to detect and obtain driving direction information of the lane in which the vehicle is located, and transmit the driving direction information of the lane in which the vehicle is located to the vehicle control device. In response, the vehicle control device receives the driving direction information of the lane in which the vehicle is located, and generates a driving decision based on the driving direction information of the lane in which the vehicle is located.

[0116] Optionally, the architecture of the vehicle control device at this time can also refer to the above Figure 4 The architecture composed of the perception module 401, the vehicle driving intention judgment module 402 and the driving decision generation module 403 in the vehicle control system shown will not be repeated here.

[0117] It can be understood that the vehicle in the embodiment of the present application is an intelligent driving vehicle and can be replaced by a terminal device. The terminal device may include transportation vehicles such as commercial vehicles, passenger cars, trains, etc., industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), robots, etc., and the embodiment of the present application does not make specific limitations on this.

[0118] The driving direction indication information of the lane in which the vehicle is located can be understood as static information about the lane perceived by the vehicle in a broad sense.

[0119] Optionally, the driving direction information may include, but is not limited to, lane direction arrow information, lane direction sign information, etc., which are not listed in detail in the present embodiment. By combining various types of perceived static lane information, the driving direction information corresponding to the lane in which the vehicle is located can be more accurately determined, thereby generating correct driving decisions and reducing driving safety risks.

[0120] Optionally, the vehicle control device obtains the driving direction indication information of the lane where the vehicle is located, specifically by extracting image data collected by a sensor on the vehicle and obtaining the driving direction indication information after a series of image data processing.

[0121] For details, please refer to Figure 6 , Figure 6 A schematic diagram of driving direction indication information provided in an embodiment of the present application.

[0122] like Figure 6 As shown, it shows the lane lines of a four-lane road at a distance before the intersection, lane guide arrow information, lane driving direction sign information (also known as sky sign information), etc.

[0123] Depend on Figure 6 It can be seen that, assuming the driver's perspective is the main direction, the four lanes can be called lane 1, lane 2, lane 3, and lane 4 from left to right. The lane line between lane 1 and lane 2 can be called lane line a, the lane line between lane 2 and lane 3 can be called lane line b, and the lane line between lane 3 and lane 4 can be called lane line c.

[0124] Based on the lane guide arrow information or lane driving direction sign information corresponding to lane 1, it can be determined that the driving direction indication information of lane 1 is a left turn. Based on the lane driving direction sign information corresponding to lane 2, it can be determined that the driving direction indication information of lane 2 is a straight or left turn. Based on the lane guide arrow information or lane driving direction sign information corresponding to lane 3, it can be determined that the driving direction indication information of lane 3 is a straight go. Based on the lane guide arrow information or lane driving direction sign information corresponding to lane 4, it can be determined that the driving direction indication information of lane 4 is a right turn. Based on lane line a, lane line b, and lane line c, it can be determined that lane changes are allowed between the four lanes. Based on lane line a and lane line b, it can be determined that lane 2 is a composite lane containing multiple driving direction indications (straight go and left turn).

[0125] Based on the above-mentioned driving direction indication information, a corresponding first driving decision can be generated to control the vehicle's driving behavior at the first intersection in front of the vehicle, and support the lane centering function of non-straight intersections. By deciding the correct driving behavior, the risk of driving safety can be reduced.

[0126] Through the embodiments of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, the driving direction indication information corresponding to the lane in which the vehicle is located can be determined more accurately based on the perceived static information about the lane, thereby generating correct driving decisions and controlling the vehicle to drive according to the driving direction indication information corresponding to the lane at the intersection, thereby reducing the risk of driving safety.

[0127] In a possible embodiment, generating the first driving decision according to the driving direction indication information in step S502 can be specifically implemented in the following manner:

[0128] First, determine the type of lane the vehicle is in based on the driving direction indication information.

[0129] Exemplarily, the type of lane the vehicle is in includes but is not limited to: straight, left turn, right turn, U-turn, straight + left turn, straight + right turn, straight + left turn + right turn, left turn + right turn, left turn + U-turn, no ground arrow, etc.

[0130] Then, according to the lane type, corresponding first driving decisions are generated, including but not limited to the following situations:

[0131] (1) When the lane where the vehicle is located is a one-way turn lane, a first driving decision is generated for controlling the vehicle to drive in the driving direction indicated by the one-way turn lane at the first intersection.

[0132] For example, when the vehicle's lane is determined to be a left-turn lane based on the driving direction indication information, the first driving decision generated is used to control the vehicle to turn left at the first intersection. For another example, when the vehicle's lane is determined to be a right-turn lane based on the driving direction indication information, the first driving decision generated is used to control the vehicle to turn right at the first intersection. For another example, when the vehicle's lane is determined to be a through lane based on the driving direction indication information, the first driving decision generated is used to control the vehicle to go straight at the first intersection. This embodiment of the present application does not list all of these.

[0133] (2) When the lane where the vehicle is located is a composite lane including a straight lane, a first driving decision is generated for controlling the vehicle to go straight at the first intersection.

[0134] For example, when the vehicle's lane is determined to be a composite lane including straight ahead + left turn based on the driving direction indication information, the first driving decision generated is used to control the vehicle to go straight ahead at the first intersection. For another example, when the vehicle's lane is determined to be a composite lane including straight ahead + right turn based on the driving direction indication information, the first driving decision generated is used to control the vehicle to go straight ahead at the first intersection. For another example, when the vehicle's lane is determined to be a composite lane including straight ahead + left turn + right turn based on the driving direction indication information, the first driving decision generated is used to control the vehicle to go straight ahead at the first intersection. The embodiments of the present application do not list all of these.

[0135] (3) When the lane where the vehicle is located is a composite lane including a left turn and a U-turn, a first driving decision is generated for controlling the vehicle to turn left at the first intersection.

[0136] (4) When the lane where the vehicle is located does not include a driving direction indication, a first driving decision is generated for controlling the vehicle to go straight at the first intersection.

[0137] (5) In the case where the vehicle's lane is a composite lane that includes both left and right turns, since it is impossible to determine a unique driving decision based solely on the driving direction indication information in the vehicle's lane, this scenario is considered to be a case where the vehicle's driving intention is unknown. Optionally, the driving decision in this case can be further determined by combining the driver's driving intention information and / or the traffic light information at the first intersection. This is not discussed here and will be described in detail later.

[0138] Optionally, the vehicle control method further includes:

[0139] Obtain traffic light information for a first intersection; determine the type of lane in which the vehicle is located based on the driving direction indication information; if the lane in which the vehicle is located is a composite lane including left and right turns, determine the first traffic light information for the first intersection based on the color state and / or countdown information in the traffic light information; generate a first driving decision based on the first traffic light information, the first driving decision being used to control the vehicle to pass through the first intersection in the driving direction corresponding to the first traffic light information or to brake before the first intersection.

[0140] It is understandable that the first traffic light mentioned above can be regarded as a conservative light, and the specific meaning of the conservative light is as follows:

[0141] For example, if the traffic light corresponding to the left-turn lane is a circular red light and the traffic light corresponding to the right-turn lane is a circular green light, the circular red light corresponding to the left-turn lane is determined as the first traffic light information for the first intersection. This means that a relatively conservative red light is selected to maximize driving safety in scenarios with unknown driving intentions. Furthermore, a first driving decision is generated based on this first traffic light information, controlling the vehicle to brake before the first intersection according to this first traffic light information and wait for the circular red light to turn green before turning left.

[0142] For another example, if the traffic light corresponding to the left-turn lane has a green countdown of 5 seconds and the traffic light corresponding to the right-turn lane has a green countdown of 20 seconds, the traffic light corresponding to the right-turn lane with a green countdown of 20 seconds is determined as the first traffic light information for the first intersection. This means that the traffic light with the longest permitted travel time is selected as the conservative light to maximize driving safety in scenarios with unknown driving intentions. Furthermore, a first driving decision is generated based on this first traffic light information, controlling the vehicle to turn right through the first intersection in the driving direction corresponding to the first traffic light information.

[0143] Through the embodiments of the present application, it is possible to conservatively select lights when the vehicle's driving intention is unknown, comply with the traffic rules set at the first intersection, and reduce the safety risk of running a red light.

[0144] Through the above embodiments, for vehicles that do not use the global navigation recommendation system in the LCC scenario, it is impossible to decide the vehicle's driving behavior at the intersection based on the navigation path planning, and thus the lane centering function for non-straight intersections is not supported. In the embodiments of the present application, corresponding driving decisions are generated based on the driving direction indication information of the lane in which the vehicle is located, and the vehicle's driving behavior at the intersection is controlled. The lane centering function for non-straight intersections is supported, and by deciding the correct driving behavior, the problem of driving safety risks can be reduced.

[0145] Optionally, when the driver's driving intention information is detected, the details can also be referred to Figure 7The vehicle control method shown generates corresponding driving decisions.

[0146] See also Figure 7 , Figure 7 A flowchart of another vehicle control method provided in an embodiment of the present application.

[0147] It is understandable that the steps in the embodiment of the present application can be regarded as the above Figure 5 or, it can be understood that the vehicle control method in the embodiment of the present application can also be regarded as an embodiment that can be executed separately, and the present application does not limit this.

[0148] The vehicle control method provided in the embodiments of the present application is applied to the field of intelligent driving technology, such as controlling a vehicle in an LCC scenario without using a global navigation recommendation system.

[0149] It is understood that the vehicle control device involved in the vehicle control method provided in the embodiment of the present application can refer to the above Figure 5 The relevant description of the vehicle control device involved in the vehicle control method shown is not repeated here.

[0150] Specifically, the vehicle control method includes but is not limited to the following steps:

[0151] S701: The vehicle control device obtains driving direction indication information of the lane where the vehicle is located.

[0152] With the above Figure 5 Step S501 in the illustrated embodiment is consistent and will not be described again here.

[0153] S702: The vehicle control device obtains the driver's driving steering intention information.

[0154] It can be understood that there is no specific order of execution between this step S702 and the above-mentioned step S701. S701 can be executed first and then S702, or S702 can be executed first and then S701, or S701 and S702 can be executed at the same time. The embodiments of the present application do not limit this.

[0155] S703: The vehicle control device generates a first driving decision according to the driving direction indication information and the driving steering intention information.

[0156] The above-mentioned driving steering intention information of the driver can be understood as a series of action responses regarding straight driving or non-straight driving made by the driver at the first intersection in front of the vehicle.

[0157] Optionally, the driver's driving intention information may include, but is not limited to, lever information, steering wheel information, and so on, which are not listed in detail in the present embodiment. By integrating the driving direction indication information of the perceived lane and the driver's driving steering intention information, the vehicle's corresponding driving intention can be more accurately determined, thereby generating correct driving decisions and reducing driving safety risks.

[0158] For details, please refer to Figure 8 , Figure 8 A schematic diagram of driving steering intention information provided in an embodiment of the present application.

[0159] like Figure 8 As shown, the steering wheel and lever of the driving control in the vehicle are shown. The driver can send driving steering intention information by operating the lever or the steering wheel.

[0160] Example 1:

[0161] When it is detected that the driver turns the steering wheel to the left, the driving steering intention information is obtained as turning left, making a U-turn, or changing lanes to the left.

[0162] Optionally, when the steering wheel is turned to the left with a small amplitude (or force), the driving steering intention information is obtained as a left lane change. When the steering wheel is turned to the left with a medium amplitude (or force), the driving steering intention information is obtained as a left turn. When the steering wheel is turned to the left with a large amplitude (or force), the driving steering intention information is obtained as a U-turn.

[0163] It is understandable that the magnitude of the steering wheel rotation amplitude can be distinguished based on the steering wheel rotation amplitude (or force) threshold. For example, when the steering wheel rotation amplitude (or force) to the left is less than the first rotation amplitude / force threshold, the driving steering intention information obtained is a left lane change. When the steering wheel rotation amplitude (or force) to the left is greater than or equal to the first rotation amplitude / force threshold and less than the second rotation amplitude / force threshold, the driving steering intention information obtained is a left turn. When the steering wheel rotation amplitude (or force) to the left is greater than or equal to the second rotation amplitude / force threshold, the driving steering intention information obtained is a U-turn.

[0164] When it is detected that the driver turns the steering wheel to the right, the driving steering intention information is obtained as turning right or changing lanes to the right.

[0165] Optionally, when the steering wheel is turned to the right with a smaller amplitude (or force), the driving steering intention information is obtained as changing lanes to the right. When the steering wheel is turned to the right with a larger amplitude (or force), the driving steering intention information is obtained as turning right.

[0166] It is understood that the magnitude of the steering wheel rotation amplitude can be distinguished based on a steering wheel rotation amplitude (or force) threshold. For example, when the steering wheel rotation amplitude (or force) to the right is less than a first rotation amplitude / force threshold, the driving steering intention information obtained is a right lane change. When the steering wheel rotation amplitude (or force) to the right is greater than or equal to the first rotation amplitude / force threshold, the driving steering intention information obtained is a right turn.

[0167] Example 2:

[0168] When it is detected that the driver pushes the lever downward (or forward), the driving intention information is obtained as turning left, making a U-turn, or changing lanes to the left.

[0169] Optionally, when the lever is pushed downward (or forward) with a small amplitude (or force), the driving intention information is obtained as a left lane change. When the lever is pushed downward (or forward) with a medium amplitude (or force), the driving intention information is obtained as a left turn. When the lever is pushed downward (or forward) with a large amplitude (or force), the driving intention information is obtained as a U-turn.

[0170] It is understood that the magnitude of the lever movement can be differentiated based on the lever movement (or force) threshold. For example, when the lever movement (or force) is less than the first lever movement / force threshold, the driving steering intention information is obtained as a left lane change. When the steering wheel is turned left by an amplitude (or force) greater than or equal to the first lever movement / force threshold and less than the second lever movement / force threshold, the driving steering intention information is obtained as a left turn. When the steering wheel is turned left by an amplitude (or force) greater than or equal to the second lever movement / force threshold, the driving steering intention information is obtained as a U-turn.

[0171] When it is detected that the driver has pushed the lever upward (or backward), the driving intention information is obtained as turning right or changing lanes to the right.

[0172] Optionally, when the lever is pushed upward (or backward) with a smaller amplitude (or force), the driving intention information is obtained as a lane change to the right. When the lever is pushed upward (or backward) with a larger amplitude (or force), the driving intention information is obtained as a right turn.

[0173] It is understood that lever lever amplitude (or force) thresholds can be used to distinguish lever lever amplitudes. For example, when the lever lever amplitude (or force) is less than a first lever lever amplitude / force threshold, the driving steering intention information is obtained as a right lane change. When the lever lever amplitude (or force) is greater than or equal to the first lever lever amplitude / force threshold, the driving steering intention information is obtained as a right turn.

[0174] It is understood that the above-mentioned steering wheel rotation direction and the direction of the lever movement are merely exemplary and should not limit the embodiments of the present application. For example, the driver may also send the driving steering intention information through voice commands, gesture commands, steering wheel combination buttons, etc. For another example, the driver may customize the method of sending the driving steering intention information, such as moving the lever twice in a row, with upward turning for a left turn and downward turning for a right turn; moving the lever only once, with upward turning for a left lane change and downward turning for a right lane change, etc., and the embodiments of the present application do not limit this.

[0175] Based on the above-mentioned driving direction indication information and driving steering intention information, a corresponding first driving decision can be generated to control the vehicle's driving behavior at the first intersection in front of the vehicle, support the lane centering function of non-straight-ahead intersections, and reduce driving safety risks by deciding correct driving behavior.

[0176] Through the embodiments of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, the fusion of the driving direction indication information of the perceived lane and the driver's driving steering intention information can more accurately determine the vehicle's corresponding driving intention, thereby generating correct driving decisions and controlling the vehicle to drive according to the vehicle's corresponding driving intention at the first intersection, thereby reducing the risk of driving safety.

[0177] In a possible embodiment, the generation of the corresponding first driving decision according to the driving direction indication information and the driving steering intention information shown in step S703 can be specifically implemented in the following manner:

[0178] When the vehicle meets the turning condition, a first driving decision is generated according to the driving direction indication information and the driving turning intention information.

[0179] When the vehicle satisfies the turning condition, the driver's driving turning intention information facing the front intersection can be interpreted as turning. In other words, when the vehicle satisfies the turning condition, the first driving decision is generated based on the driving direction indication information and the driving turning intention information.

[0180] Optionally, the above-mentioned turning conditions include at least one of the following: the distance between the vehicle and the first intersection is less than a first threshold, and the steering operation force corresponding to the driving steering intention information is greater than a second threshold.

[0181] It is understood that when the distance between the vehicle and the first intersection is less than a first threshold, the vehicle can be considered to have the distance and time to approach the first intersection to execute the turn, thus meeting the turning condition. This first threshold is not a fixed value and can be adjusted according to different application scenarios.

[0182] It can be understood that when the steering operation force corresponding to the driving steering intention information is greater than the second threshold, it can be considered that the steering intention is obvious, and then the driving steering intention information is considered to be steering, which meets the steering conditions. The steering operation force can refer to the steering force of the lever or the steering force of the steering wheel, etc.

[0183] Optionally, when the driver's steering intention information is obtained but the vehicle does not meet the above steering conditions, the scene can be understood as a vehicle lane change scene. At this time, the first driving decision is generated according to the driving direction indication information. For details, please refer to the above Figure 5 The relevant description of step S502 in the vehicle control method is not repeated here.

[0184] Optionally, whether the current driving scene is a vehicle lane change scene can also be identified based on whether the vehicle meets the lane change conditions.

[0185] For example, when the vehicle meets the lane change conditions, the first driving decision is generated according to the driving direction indication information. For details, please refer to the above Figure 5 The description of step S502 in the vehicle control method is not repeated here. Alternatively, if the vehicle does not meet the lane change conditions, a first driving decision is generated based on the driving direction indication information and the driving intention information. For details, please refer to the description of step S703 above, which is not repeated here.

[0186] Among them, the above lane change conditions include at least one of the following: the distance between the vehicle and the first intersection is greater than or equal to a first threshold, the steering operation force corresponding to the driving steering intention information is less than or equal to a second threshold, and the boundary of the lane where the vehicle is located is a non-solid line and a non-side lane.

[0187] It is understood that when the distance between the vehicle and the first intersection is greater than or equal to the first threshold, the vehicle can be considered to have sufficient distance and time to complete the lane change and meet the lane change conditions. This first threshold is not a fixed value and can be adjusted according to different application scenarios.

[0188] It can be understood that when the steering operation force corresponding to the driving steering intention information is less than or equal to the second threshold, it can be considered that the steering intention is insufficient, and then the driving steering intention information is considered to be changing lanes rather than turning, which meets the lane changing conditions. The steering operation force can refer to the steering force of the lever or the steering force of the steering wheel, etc.

[0189] It can be understood that when the boundary of the lane where the vehicle is located is not a solid line and is not a side lane, it can be considered that the vehicle has space to change lanes and complies with traffic regulations and meets the lane change conditions.

[0190] Through the embodiments of the present application, different driving decisions are generated in different ways according to whether the vehicle meets the turning conditions or the lane changing conditions, which can improve the accuracy of the driving decisions and ensure the safety of the vehicle at the first intersection.

[0191] In a possible embodiment, when the driver's driving steering intention information is obtained and the vehicle meets the steering conditions, the first driving decision is generated by combining the driving direction indication information and the driving steering intention information. The specific implementation can be as follows:

[0192] First, determine the type of lane the vehicle is in based on the driving direction indication information.

[0193] Exemplarily, the type of lane the vehicle is in includes but is not limited to: straight, left turn, right turn, U-turn, straight + left turn, straight + right turn, straight + left turn + right turn, left turn + right turn, left turn + U-turn, no ground arrow, etc.

[0194] Then, the lane type and the driving steering intention information are combined to generate corresponding first driving decisions, including but not limited to the following situations:

[0195] (1) When the driving steering intention information indicates a right turn and the lane in which the vehicle is located is a lane that includes a right turn, a first driving decision is generated for controlling the vehicle to turn right at a first intersection.

[0196] (2) When the driving steering intention information indicates a left turn and the lane in which the vehicle is located is a lane that includes a left turn, a first driving decision is generated for controlling the vehicle to turn left at the first intersection.

[0197] (3) When the driving steering intention information indicates a left turn and the lane where the vehicle is located is a lane that includes a U-turn but does not include a left turn, a first driving decision is generated for controlling the vehicle to make a U-turn at the first intersection.

[0198] Optionally, when the driving steering intention information conflicts with (is different from) the driving direction indication information, a first driving decision can be generated based on the driving steering intention information, or a first driving decision can be generated based on the driving direction indication information, and so on. The embodiments of the present application do not limit this.

[0199] By combining the driving direction indication information and the driving steering intention information in the above embodiment to generate the corresponding first driving decision, for vehicles that do not use the global navigation recommendation system in the LCC scenario, the driving direction indication information of the perceived lane and the driving steering intention information of the driver are integrated to more accurately determine the corresponding driving intention of the vehicle, thereby generating a correct driving decision, controlling the vehicle to drive according to the corresponding driving intention of the vehicle at the first intersection, supporting the lane centering function at non-straight intersections, and reducing driving safety risks.

[0200] Optionally, when it is detected that there is traffic light information at the first intersection, please refer to Figure 9 The illustrated vehicle control method generates a corresponding second driving decision.

[0201] See also Figure 9 , Figure 9 A flowchart of another vehicle control method provided in an embodiment of the present application.

[0202] It is understandable that the steps in the embodiment of the present application can be regarded as the above Figure 5 or Figure 7 or, it can be understood that the vehicle control method in the embodiment of the present application can also be regarded as an embodiment that can be executed separately, and the present application does not limit this.

[0203] The vehicle control method provided in the embodiments of the present application is applied to the field of intelligent driving technology, such as controlling a vehicle in an LCC scenario without using a global navigation recommendation system.

[0204] It is understood that the vehicle control device involved in the vehicle control method provided in the embodiment of the present application can refer to the above Figure 5 The relevant description of the vehicle control device involved in the vehicle control method shown is not repeated here.

[0205] Specifically, the vehicle control method includes but is not limited to the following steps:

[0206] S901: The vehicle control device obtains traffic light information at a first intersection.

[0207] S902: The vehicle control device generates a second driving decision based on the traffic light information at the first intersection and the first driving decision.

[0208] Among them, the above-mentioned first driving decision can be specifically referred to the relevant description of the above-mentioned step S502 or S703, which will not be repeated here.

[0209] The traffic light information at the first intersection may include, but is not limited to, traffic light information set at the first intersection, for guiding vehicles and pedestrians to pass through the first intersection safely and orderly.

[0210] For details, please refer to Figure 10 , Figure 10 A schematic diagram of traffic light information provided in an embodiment of the present application.

[0211] like Figure 10 As shown, a traffic light is set at the first intersection, which is controlled by a road traffic signal controller to guide vehicles and pedestrians to pass safely and orderly.

[0212] Depend on Figure 10 As can be seen, assuming the driver's perspective is the primary direction, the three lanes can be referred to as Lane 1, Lane 2, and Lane 3, respectively, from left to right. Vehicle 100 is traveling in Lane 2 and is about to reach the first intersection. Traffic light information is set at the first intersection to guide vehicles in Lanes 1, 2, and 3 to pass safely and orderly at the first intersection. At the current moment, the traffic light information corresponding to Lane 1 is a circular red light, indicating that vehicles in Lane 1 are prohibited from passing and must brake before the first intersection and wait for the circular red light to turn green. The traffic light information corresponding to Lane 2 is a green countdown of 20 seconds, indicating that vehicles in Lane 2 have 20 seconds left to pass. The traffic light information corresponding to Lane 3 is a green countdown of 5 seconds, indicating that vehicles in Lane 3 have 5 seconds left to pass.

[0213] Based on the above-mentioned first driving decision and the traffic light information at the first intersection, a corresponding second driving decision is generated to control the vehicle's driving behavior at the intersection. By deciding the correct driving behavior, the risk of running a red light can be reduced and the traffic rules set at the first intersection can be complied with.

[0214] Through the embodiments of the present application, for vehicles that do not use the global navigation recommendation system in the LCC scenario, the integration of the first driving decision and the traffic light information at the first intersection can more accurately determine the vehicle's corresponding driving intention, generate correct driving decisions that comply with traffic rules, and control the vehicle to drive according to the vehicle's corresponding driving intention at the first intersection, and comply with the traffic rules set at the first intersection, thereby reducing the risk of running red lights.

[0215] In a possible embodiment, the step S902 of generating the corresponding second driving decision based on the traffic light information at the first intersection and the first driving decision can be implemented in the following manner:

[0216] In the case where the first driving decision is non-straight driving, second traffic light information of the first intersection corresponding to the first driving decision is determined; based on the second traffic light information, a second driving decision is generated, and the second driving decision is used to control the vehicle to pass through the first intersection in the driving direction corresponding to the first driving decision or to brake before the first intersection.

[0217] It can be understood that when the first driving decision generated is non-straight driving (for example, left turn, right turn, U-turn), the second traffic light information of the first intersection corresponding to the first driving decision is determined, and the vehicle is controlled to pass through the first intersection in the driving direction corresponding to the first driving decision or brake before the first intersection according to the second traffic light information.

[0218] Through the embodiments of the present application, when the first driving decision is not to go straight, a correct second driving decision that complies with traffic rules can be generated, and the vehicle can be controlled to drive in the driving direction corresponding to the first driving decision at the first intersection, and comply with the traffic rules set at the first intersection, thereby reducing the risk of running a red light.

[0219] Optionally, in the above Figure 5 、 Figure 7 、 Figure 9 In the vehicle control method shown, the vehicle control method further includes:

[0220] When the first driving decision is non-straight driving, a third driving decision is generated.

[0221] The third driving decision is also used to instruct the vehicle to output a takeover request, and the takeover request is used to request the driver to take over the vehicle at the first intersection.

[0222] Through the embodiments of the present application, when the vehicle is controlled to move non-straight at the first intersection (for example, turning left, turning right, or making a U-turn), a third driving decision can be generated accordingly, instructing the vehicle to output a takeover request, which is used to request the driver to take over the vehicle at the first intersection, and the driver completes the intersection turning operation.

[0223] Optionally, in the above Figure 5 、 Figure 7 、 Figure 9 In the vehicle control method shown, the vehicle control method further includes:

[0224] When the first driving decision is non-straight driving, a fourth driving decision is generated.

[0225] The fourth driving decision is further used to control the driving speed of the vehicle before the first intersection to be less than a third threshold.

[0226] It can be understood that when the first driving decision generated controls the vehicle to go non-straight at the first intersection (for example, turn left, turn right, or make a U-turn), a fourth driving decision can also be generated accordingly to control the vehicle's driving speed before the first intersection to be less than a third threshold. The third threshold is not a fixed value and can be adjusted according to different driving application scenarios.

[0227] Through the embodiments of the present application, speed limits are set before vehicles pass through non-straight intersections, which can avoid possible safety accidents caused by excessive speed after the vehicle enters the intersection and reduce driving risks in the intersection.
