[0051] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0052] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0053] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario according to an exemplary embodiment, such as... Figure 1 As shown, the application scenario can include: the vehicle's HV (101) and the vehicle in front (102).

[0054] In an optional embodiment, vehicles on the road receive and transmit information to each other via vehicle-to-everything (V2X) wireless communication technology. This application scenario can occur at traffic light intersections or congested road sections, where multiple vehicles around the vehicle receive location information of other vehicles within a certain range via V2X, while simultaneously transmitting their own location information. At traffic light intersections or congested road sections, the vehicle (HV) (101) obtains the location of vehicles within a certain range around it via V2X, determines the vehicle in front of it (102) based on the obtained location information, and receives a timely reminder if the vehicle in front is in a starting state.

[0055] It should be noted that the following diagram shows one possible sequence of steps, and it is not strictly required to follow this order. Some steps can be executed in parallel without interdependence. The vehicle status information (including but not limited to starting status information, non-starting status information, etc.) and driving data (including but not limited to first driving data, second driving data, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties.

[0056] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for providing a preceding vehicle start-up warning according to an exemplary embodiment, such as... Figure 2 As shown, the reminder method may include:

[0057] S201, acquire first driving data of the first vehicle and second driving data broadcast by multiple second vehicles through vehicle wireless communication technology.

[0058] In this embodiment of the disclosure, the first vehicle can refer to any vehicle on the road. The first driving data can refer to the driving data of the first vehicle, which may include the vehicle's speed and location data. Specifically, the first driving data may include the first vehicle's yaw rate, speed, heading angle, and latitude and longitude. The second vehicle can refer to other vehicles on the road besides the first vehicle. Specifically, it can refer to other vehicles within a certain range of the first vehicle, where the certain range is based on the range that the vehicle-to-everything (V2X) wireless communication technology can receive. The second driving data can refer to the driving data of the second vehicle, specifically, it may be the latitude and longitude of the second vehicle.

[0059] In one example, it is possible to acquire second driving data broadcast by multiple second vehicles via vehicle wireless communication technology, for example, to receive second driving data broadcast by multiple second vehicles via vehicle wireless communication technology in real time.

[0060] In one possible implementation, latitude and longitude coordinates broadcast by multiple second vehicles are simultaneously received via vehicle-to-vehicle wireless communication technology during the operation of the first vehicle.

[0061] During its journey, the first vehicle simultaneously receives second driving data from multiple second vehicles, thereby determining the real-time positions of these vehicles and preventing collisions.

[0062] In another example, acquiring second driving data broadcast by multiple second vehicles via vehicle wireless communication technology can also be done when the speed of the first vehicle is lower than a preset speed.

[0063] The preset speed can refer to a pre-defined speed that indicates the vehicle is in a deceleration state. As an example, the preset speed can be less than a speed threshold. In this case, when the speed of the first vehicle drops to the preset speed, second driving data can be acquired, for example, the acquisition and processing of the second driving data can be initiated.

[0064] In one possible implementation, the speed of a first vehicle can be obtained by a sensor, and if the speed of the first vehicle is lower than a preset speed, second driving data broadcast by multiple second vehicles via vehicle wireless communication technology can be obtained, wherein the sensor can be a speed sensor.

[0065] In another possible implementation, detecting that the speed of the first vehicle is lower than a preset speed can be achieved through vehicle wireless communication technology, which can be used to determine that the speed of the first vehicle is lower than the preset speed and to acquire second driving data broadcast by multiple second vehicles through vehicle wireless communication technology.

[0066] Optionally, second driving data of multiple second vehicles can be obtained within a predetermined time period before the speed of the first vehicle reaches the preset speed, wherein the predetermined time period can be 1s, 3s, or 5s, and this disclosure does not limit it.

[0067] Optionally, second driving data of multiple second vehicles can be obtained when the speed of the first vehicle is lower than a preset speed.

[0068] Acquiring second driving data from multiple second vehicles when the first vehicle reaches a preset speed can enhance resource utilization and make the data more accurate and effective.

[0069] S203, based on the first driving data and the second driving data, determine the target vehicle from a plurality of second vehicles, wherein the target vehicle is the vehicle preceding the first vehicle.

[0070] In one example, the first driving data could be the heading angle and position of the first vehicle, and the second driving data could be the heading angle and position of the second vehicle.

[0071] In one possible implementation, information on multiple second vehicles within a certain range from the first vehicle can be determined based on the first and second driving data. This information on multiple second vehicles is then compared to obtain a comparison result. Based on the comparison result, the target vehicle is determined from among the multiple second vehicles. The "certain range" can be 50 meters, 100 meters, etc., and is not limited thereto in this disclosure.

[0072] For example, based on the positions of the first vehicle and the second vehicle, the positions of multiple second vehicles are compared. For instance, the second vehicle that is closer to the first vehicle and within 90° of the first vehicle's heading angle is selected as the target vehicle. Here, distance can refer to the length from the center of the first vehicle to the center of the second vehicle, which can be 3 meters, 5 meters, or 8 meters, and this disclosure does not limit it.

[0073] S205, when the first vehicle is stationary, detects the starting status information of the target vehicle.

[0074] As an example, the starting status information can refer to the driving status of the target vehicle. The driving status can be either a non-starting state or a starting state. Specifically, the starting state is when the speed of the target vehicle exceeds a threshold.

[0075] In one possible implementation, when the first vehicle is stationary, the speed of the target vehicle can be acquired via a sensor to detect the target vehicle's starting status information. The sensor can be a speed sensor.

[0076] In another possible implementation, when the first vehicle is stationary, the speed of the target vehicle can be obtained through vehicle wireless communication technology to detect the starting status information of the target vehicle.

[0077] S207 If the starting status information indicates that the target vehicle is in a starting state, a starting reminder for the vehicle in front is issued.

[0078] As an example, if the starting status information indicates that the target vehicle is in a starting state, a prompt message can be displayed on the terminal to remind the vehicle in front to start.

[0079] As another example, if the status information indicates that the target vehicle is in a starting state, a voice broadcast can be used to remind the vehicle in front to start.

[0080] When the target vehicle is detected to be starting, the driver should be promptly alerted to prevent traffic congestion caused by the driver's inattention.

[0081] like Figure 3 As shown, Figure 3 This is a flowchart illustrating the determination of a target vehicle according to an exemplary embodiment. In one possible implementation, S203 above may include the following steps:

[0082] S301, Based on the first driving data, determine the driving type of the first vehicle.

[0083] In one example, the driving type includes straight driving and curved driving.

[0084] In the embodiments of this disclosure, the travel curvature C, radius of curvature r, and coordinates (x0, y0) of the first vehicle relative to its current position (x1, y1) are calculated based on the yaw rate, velocity, heading angle, and current position (x1, y1) of the first vehicle. The travel curvature calculation formula is Formula (1):

[0085] Driving curvature

[0086] Among them, W r yaw rate is the yaw rate of the first vehicle (rad / s), and v is the speed of the first vehicle (VehicleSpeed) (m / s).

[0087] The formula for calculating the radius of curvature is formula (2):

[0088] radius of curvature

[0089] The formula for calculating the coordinates of the center of curvature of the first vehicle relative to its current position is formula (3):

[0090] x0=x1+r*cosα, y0=y1-r*sinα (3)

[0091] Wherein, the current position (x1, y1) of the first vehicle is a coordinate point established in the coordinate system with the current position of the first vehicle as the center, that is, with (x1, y1) as the center. As an example, (x1, y1) can be (0, 0), and α is the heading angle of the first vehicle.

[0092] In the embodiments of this disclosure, if any one of the following three conditions is met: Wr = 0; the speed of the first vehicle is < 1 m / s; and the radius of curvature of the first vehicle is ≥ 2500 m, the driving data of the first vehicle can be determined to be straight-line driving; otherwise, it is curved driving.

[0093] S303, based on the driving type of the first vehicle, determine the target vehicle from a plurality of second vehicles.

[0094] like Figure 4 As shown, Figure 4 This is a flowchart illustrating the process of determining a target vehicle while driving in a straight line, according to an exemplary embodiment. Step S303 may include the following steps:

[0095] S401, when the driving type is straight driving, obtain the relative distance and relative azimuth angle of the second vehicle relative to the first vehicle.

[0096] In one example, the formula for calculating the relative distance between the second vehicle and the first vehicle is formula (4):

[0097]

[0098] Among them, L AB This is the relative distance between the second vehicle and the first vehicle. R is the Earth's radius, which is taken as 6378137 in this disclosure. (lat) A ,long A (lat) represents the latitude and longitude of the first vehicle. B ,long B () represents the latitude and longitude of the second vehicle.

[0099] In the embodiments disclosed herein, such as Figure 6 As shown, Figure 6 This is a schematic diagram of a first vehicle and a second vehicle based on a coordinate system, according to an exemplary embodiment, wherein the formula for calculating the north azimuth angle β of the second vehicle relative to the first vehicle is formula (5).

[0100]

[0101] The relative azimuth angle γ is the difference between the north azimuth angle β of the second vehicle relative to the first vehicle and the heading angle α of the first vehicle.

[0102] In the embodiments of this disclosure, the latitude and longitude of the first vehicle and the second vehicle are obtained based on vehicle wireless communication technology, and the relative distance L between the first vehicle and the second vehicle is calculated by substituting them into the formula for calculating the relative distance between the first vehicle and the second vehicle. AB The latitude and longitude of the first vehicle and the latitude and longitude of the second vehicle are substituted into the formula for calculating the north azimuth angle of the second vehicle relative to the first vehicle to calculate the north azimuth angle β of the second vehicle relative to the first vehicle. The difference between the north azimuth angle β of the second vehicle relative to the first vehicle and the heading angle α of the first vehicle obtained based on vehicle wireless communication technology is the relative azimuth angle γ of the second vehicle relative to the first vehicle.

[0103] S403, based on the relative distance and relative azimuth angle, determine the first position of the second vehicle relative to the first vehicle.

[0104] In the embodiments disclosed herein, such as Figure 7 As shown, Figure 7 This is a schematic diagram illustrating a first position of a second vehicle relative to a first vehicle during straight-line travel, according to an exemplary embodiment.

[0105] In one example, the first position could refer to the position of the second vehicle relative to the first vehicle while traveling in a straight line.

[0106] In embodiments of this disclosure, based on the relative distance L of the second vehicle relative to the first vehicle AB Given the relative azimuth angle γ, the longitudinal distance (X) of the second vehicle relative to the first vehicle and the lateral distance (Y) of the second vehicle relative to the first vehicle are obtained using trigonometric formulas. The formula for calculating the longitudinal distance is formula (6):

[0107] X = L AB ×cosγ (6)

[0108] The formula for calculating the lateral distance is formula (7):

[0109] Y = L Ab ×sinγ (7)

[0110] In embodiments of this disclosure, a plurality of second vehicles determine a first position relative to a first vehicle based on X and Y.

[0111] S405, Based on the first location, determine the target vehicle from a plurality of second vehicles.

[0112] In the embodiments disclosed herein, such as Figure 9 As shown, Figure 9 This is a schematic diagram illustrating a region division according to an exemplary embodiment.

[0113] In this embodiment, a target classification algorithm (TC) is used to divide the area surrounding the first vehicle. The area division diagram based on the target classification algorithm can be a six-square grid, a nine-square grid, etc. The area division diagram shown in this embodiment is a nine-square grid. The lane width can be determined by receiving road information broadcast by the roadside unit (RSU) using vehicle-to-everything (V2X) wireless communication technology, and the vehicle length can be flexibly set according to requirements. The target classification algorithm determines the first position of multiple second vehicles relative to the first vehicle in the area division diagram based on the X and Y coordinates of multiple second vehicles relative to the first vehicle, and selects the second vehicle at the "front vehicle" position as the target vehicle. The vehicle length can be 3 meters, 5 meters, or 8 meters, and this disclosure does not limit it.

[0114] like Figure 5 As shown, Figure 5This is a flowchart illustrating a vehicle curve driving method to determine a target vehicle according to an exemplary embodiment. Step S303 may further include the following steps:

[0115] S501, when the first vehicle is traveling on a curve, obtain the lateral and longitudinal distances of the second vehicle relative to the first vehicle.

[0116] In the embodiments disclosed herein, such as Figure 10 As shown, Figure 10 This is a schematic diagram illustrating the second position of a second vehicle relative to a first vehicle during curved driving, according to an exemplary embodiment.

[0117] As an example, the lateral distance is the difference between the radius of curvature of the first vehicle and the distance from the center of the curvature circle of the first vehicle to the second vehicle (abbreviated as Z), and the longitudinal distance is the length of the arc corresponding to the center of curvature circle of the first vehicle (abbreviated as Q).

[0118] In this embodiment, the relative distance L between the first vehicle and the second vehicle is calculated by substituting the latitude and longitude of the first vehicle and the second vehicle into the formula for calculating the relative distance between the first vehicle and the second vehicle and the formula for calculating the due north azimuth angle of the second vehicle relative to the first vehicle. AB And the relative azimuth angle γ, the specific formula is as shown above, and will not be repeated here. A coordinate system is established with the first vehicle as the origin, that is, the coordinates of the first vehicle are (0,0), and the coordinates of the second vehicle relative to the coordinates of the first vehicle in the coordinate system are calculated as (x2, y2). The calculation method of the curvature center coordinates and the curvature radius of the first vehicle is as shown above, and will not be repeated here. Based on the first vehicle, the second vehicle and the curvature center coordinates of the first vehicle, the central angle θ can be obtained based on the cosine formula of the trigonometric function. The arc calculation formula is formula (8):

[0119] Arc L = n × π × r / 180 (8)

[0120] Where n is the degree measure of the central angle θ and r is the radius of curvature, L can be obtained, which is the longitudinal distance Q of the second vehicle relative to the first vehicle. The distance from the center of curvature of the first vehicle to the second vehicle is calculated based on the coordinates of the second vehicle and the coordinates of the center of curvature of the first vehicle. The difference between the radius of curvature of the first vehicle and the distance from the center of curvature of the first vehicle to the second vehicle is the lateral distance Z of the second vehicle relative to the first vehicle.

[0121] S503, based on the lateral and longitudinal distances, determines the second position of the second vehicle relative to the first vehicle.

[0122] In one example, the second position could refer to the position of the second vehicle relative to the first vehicle while traveling along a curve.

[0123] In this embodiment of the disclosure, a plurality of second vehicles determine a second position relative to the first vehicle based on Z and Q.

[0124] S505, based on the second position, identifies the target vehicle from a plurality of second vehicles.

[0125] like Figure 9 As shown, Figure 9 This is a schematic diagram illustrating a region division according to an exemplary embodiment.

[0126] In this embodiment of the disclosure, the target classification algorithm determines multiple second positions of the second vehicle relative to the first vehicle in the region division diagram based on the Z and Q values ​​of the second vehicle relative to the first vehicle, and selects the second vehicle at the "front vehicle" position as the target vehicle.

[0127] like Figure 8 As shown, Figure 8 This is a flowchart illustrating a preceding vehicle starting warning according to an exemplary embodiment. Step S207 may include the following steps:

[0128] S801, if the starting status information indicates that the target vehicle is in a starting state, generate a starting reminder message.

[0129] In the embodiments of this disclosure, the start-up reminder information may refer to the instruction information reminding the driver to start the vehicle, specifically, it may be voice information, text information, or image information.

[0130] S803, the starting reminder information is sent to the target terminal to remind the vehicle in front to start. The target terminal is any one of the following: vehicle display terminal, vehicle voice terminal, or mobile terminal.

[0131] When the target vehicle is detected to be starting, the driver should be promptly alerted to prevent traffic congestion caused by the driver's inattention.
