[0059] Figure 1 A method flow chart of a vehicle communication method provided in an embodiment of the present application is shown as follows: Figure 1 As shown, the vehicle communication method is executed by a first vehicle and includes the following steps:

[0060] Step 101: Acquire trajectory information input by a first user.

[0061] The first user is located in the first vehicle, and the trajectory information includes a starting point and an ending point.

[0062] Step 102: Determine a second vehicle to be connected based on the trajectory information.

[0064] Step 103: Send the first communication information to the second vehicle.

[0065] The first communication information includes first identity information and first interaction information. The first identity information is displayed on the second vehicle before the first interaction information. The first identity information is used for the second user to determine whether to display the first interaction information. The second user is located in the second vehicle.

[0066] A vehicle communication method provided in an embodiment of the present application is applied to a first vehicle, and determines a second vehicle to be connected based on trajectory information input by a first user and sends first communication information to the second vehicle, so that a communication connection between vehicles can be established quickly and accurately based on the trajectory information input by the user, thereby improving the efficiency of information transmission between vehicles; in addition, the first communication information sent by the first vehicle to the second vehicle includes first identity information and first interaction information, wherein the first identity information is displayed on the second vehicle before the first interaction information, and the first identity information is used for the second user to determine whether to display the first interaction information, so that the second user in the second vehicle can determine whether to interact with the second vehicle based on the first identity information and then display the first interaction information, and the identity information and interaction information are sent to the second vehicle at the same time, further improving the efficiency of information transmission between vehicles.

[0067] In some embodiments, determining a second vehicle to be connected based on the trajectory information includes:

[0068] Determine a first track direction according to the starting point and the ending point, where the first track direction is the direction from the starting point to the ending point;

[0069] The first track direction is mapped with the position of the first vehicle as the origin, and the vehicle closest to the first vehicle in the first track direction is determined as the second vehicle.

[0070] In some embodiments, determining a second vehicle to be connected based on the trajectory information includes:

[0071] receiving and displaying third identity information sent by a third vehicle, where the third vehicle is determined based on the starting point and the ending point, and the third identity information includes appearance information of the third vehicle;

[0072] In response to an input operation by the first user, obtaining an updated end point, wherein the input operation is used to indicate that the third vehicle is different from the second vehicle, and the input operation is an operation of updating the trajectory information with the end point as the origin;

[0073] A second vehicle is determined based on the starting point, the ending point, and the updated ending point.

[0074] In some embodiments, determining the second vehicle based on the starting point, the ending point, and the updated ending point includes:

[0075] Determine a first trajectory direction according to the starting point and the updated end point, the first trajectory direction being a direction from the starting point to the updated end point;

[0076] Determine a second trajectory direction according to the end point and the updated end point, the second trajectory direction being a direction from the end point to the updated end point;

[0077] The first trajectory direction is mapped with the position of the first vehicle as the origin, and the second trajectory direction is mapped with the position of the third vehicle indicated by the end point as the origin, and the vehicle at the intersection of the first trajectory direction and the second trajectory direction and closest to the first vehicle and the third vehicle is determined as the second vehicle.

[0078] In some embodiments, sending the first communication to the second vehicle includes:

[0079] Within the first signal transmission range, the first communication information is sent to the second vehicle, wherein the first signal transmission range is the range of a sector-shaped area with the position of the first vehicle as the center, the line between the first vehicle and the second vehicle as the radius, and the central angle of the circle being the set angle.

[0080] In some embodiments, the method further comprises:

[0081] receiving second communication information sent by a second vehicle, where the second communication information includes second identity information and second interaction information;

[0082] Displaying the second identity information;

[0083] In response to a first operation of the first user, displaying second interaction information, wherein the first operation is used to instruct the first user to confirm the communication connection between the first vehicle and the second vehicle;

[0084] In response to a second operation of the first user, a rejection message is sent to the second vehicle, wherein the second operation is used to instruct the first user to reject the communication connection between the first vehicle and the second vehicle.

[0085] The embodiment of the present application also provides a method flow chart of another vehicle communication method. The method can be executed by the first vehicle, and specifically can be executed by the first terminal 01 carried by the first vehicle. Figure 1 and Figure 2 As shown, the vehicle communication method includes the following steps:

[0086] Step 101: Acquire trajectory information input by a first user.

[0087] The first user is located in the first vehicle. In some embodiments, the first user may be located in the driver's seat of the first vehicle. In other embodiments, the first user may be located elsewhere in the first vehicle.

[0088] The trajectory information may include at least a starting point and an ending point. The trajectory information input by the first user is obtained to determine the position of the second vehicle to be communicated with the first vehicle.

[0089] In the embodiments of this application, Figure 3As shown, the first terminal 01 may include a first identity storage module 101, a first information collection module 102, a first processing module 103, a first signal receiving module 104, and a first signal sending module 105. The first identity storage module 101 may include a first shallow memory 1011 and a first deep memory 1012. The first information collection module 102 may include a first video collection component 1021, a first voice collection component 1022, a first pre-stored information storage component 1023, and a first touch screen 1024. The first signal receiving module 104 may include a first signal access selection component 1041, a first display screen 1042, and a first voice prompt component 1043. The first processing module 103 may be signal-connected to the first information collection module 102, the first identity storage module 101, the first signal sending module 105, and the first signal receiving module 104. Step 201 may be specifically performed by the touch screen in the first vehicle. The first touch screen 1024 may be divided into an X*Y dot matrix and used to capture the coordinates of a series of contact points on the first touch screen 1024 when the first user inputs trajectory information.

[0090] Exemplarily, the first touch screen 1024 can be set at the center console of the vehicle, so that the first user in the driving seat can blindly operate the first touch screen 1024 with his right hand (the hand usually used to shift gears) without affecting the driving of the vehicle. The first user can input trajectory information on the first touch screen 1024 through a sliding gesture. The trajectory information can be a line segment with a starting point and an ending point. Alternatively, the trajectory information can also be a curve with a starting point and an ending point. Regardless of the shape of the trajectory information, the first vehicle can obtain the position of the starting contact point and the position of the ending contact point of the first user on the first touch screen 1024, and determine the starting point of the trajectory information according to the position of the starting contact point, and determine the ending point of the trajectory information according to the position of the ending contact point.

[0091] Step 102: Determine a second vehicle to be connected based on the trajectory information.

[0092] In the trajectory information input by the first user, the position of the starting point can be considered to indicate the position of the first vehicle, and specifically can be considered to correspond to the driving position of the first vehicle. The position of the ending point can be considered to indicate the position of the second vehicle that the first user wants to connect to, so that the positional relationship between the starting point and the ending point indicates the positional relationship between the first vehicle and the second vehicle to be connected. Therefore, in the embodiment of the present application, the second vehicle to be connected can be quickly and accurately determined based on the trajectory information input by the first user, without having to complete the mutual authentication of the identity identification between the vehicles in advance and then determine the interacting vehicle based on the identity identification. Even completely unfamiliar vehicles can achieve communication interaction, thereby improving the efficiency of information transmission between vehicles.

[0093] In some embodiments, this step may be performed by the first processing module 103 in the first vehicle. In other words, the first processing module 103 may determine the second vehicle to be connected based on the trajectory information, so as to quickly establish a communication connection between the first vehicle and the second vehicle through the trajectory information, thereby achieving communication interaction between the first vehicle and the second vehicle.

[0094] In some embodiments, this step may specifically include the following steps:

[0095] Step 2021: Determine a first track direction based on the starting point and the ending point, wherein the first track direction is the direction from the starting point to the ending point.

[0096] In this step, a ray can be established with the starting point as the origin, and the ray passes through the end point. The direction of the ray can be considered the first trajectory direction. The first trajectory direction indicates the positional relationship between the starting point and the end point. As described above, the positional relationship between the starting point and the end point can indicate the positional relationship between the first vehicle and the second vehicle to be connected. Therefore, the first trajectory direction can also be used to indicate the positional relationship between the first vehicle and the second vehicle to be connected.

[0097] In some embodiments, the trajectory information may only include a starting point and an ending point, and after determining the positional relationship between the starting point and the ending point, the position of the second vehicle to be connected can be determined based on the positional relationship and the position of the first vehicle.

[0098] In some embodiments, the first processing module 103 may determine the first trajectory direction according to the starting point and ending point of the trajectory information input by the first user on the first touch screen 1024 , thereby enabling the first signal sending module 105 to send the first communication information to the second vehicle according to the first trajectory direction.

[0099] Step 2022 : Map the first track direction with the position of the first vehicle as the origin, and determine the vehicle closest to the first vehicle in the first track direction as the second vehicle.

[0100] In the embodiment of this application, Figure 5 As shown, the first trajectory direction determined based on the trajectory information indicates the positional relationship between the first vehicle and the second vehicle to be connected, specifically the angular relationship between the positions of the first and second vehicles. Therefore, the second vehicle to be connected can be determined based on the position of the first vehicle and the first trajectory direction. In this step, "mapping the first trajectory direction with the position of the first vehicle as the origin" can be understood as determining a target direction with the position of the first vehicle as the origin, with the target direction being parallel to the first trajectory direction.

[0101] The first trajectory direction is the direction from the starting point to the ending point. In other words, the first trajectory direction is based on the starting point, and the starting point corresponds to the position of the first vehicle. This first trajectory direction is then mapped to reality, and a target direction parallel to the first trajectory direction is determined with the first vehicle's position as the origin. This target direction can be considered the direction of the second vehicle indicated by the first user, and the second vehicle to be connected can be determined in this target direction. There may be more than one vehicle in this target direction. Considering that only unobstructed vehicles are visible in the first user's field of view, and that the first user may not initiate a communication request until the first and second vehicles are close to each other and the first user observes the second vehicle, the vehicle closest to the first vehicle in the first trajectory direction can be determined as the second vehicle.

[0102] The above method for determining the second vehicle may be applicable to a situation where there is no other vehicle between the first vehicle and the second vehicle, so as to improve the accuracy of determining the second vehicle to be connected.

[0103] Due to factors such as computational errors and user input errors, the second vehicle currently identified based on the trajectory information may or may not be the vehicle the first user actually wants to connect to. Therefore, the first user must verify the identity of the second vehicle identified based on the trajectory information to improve the accuracy of the second vehicle to be connected. For ease of distinction, in the following description, a vehicle identified solely based on the start and end points in the trajectory information, without confirmation by the first user, is referred to as the "third vehicle."

[0104] In some embodiments, after determining the third vehicle according to steps 2021 to 2022 above, the first vehicle may send a first communication message to the third vehicle. After receiving the first communication message, the third vehicle may feedback the identity information of the third vehicle to the first vehicle (hereinafter referred to as "third identity information" for ease of distinction). The first vehicle may receive and display the third identity information of the third vehicle for the user to confirm whether the third vehicle is the second vehicle to be connected. If the first user confirms that the third vehicle connected for the first time is not the second vehicle to be connected based on the third identity information, the trajectory information may be updated. The first vehicle re-determines the third vehicle based on the updated trajectory information, and may repeat the above steps until the determined third vehicle is the second vehicle to be connected.

[0105] In other words, in some embodiments, determining the second vehicle to be connected based on the trajectory information may further specifically include the following steps:

[0106] Step 2023: Receive and display the third identity information sent by the third vehicle.

[0107] The third vehicle is determined based on the starting point and ending point as described in steps 2021 and 2022 above. The third identity information may include the appearance information of the third vehicle. This allows the first user to directly determine the third vehicle identified by the first vehicle based on the trajectory information based on this appearance information and determine whether the third vehicle is the vehicle with which communication is intended. This allows the first user to make timely adjustments if the third vehicle is not the vehicle with which communication is intended. In some embodiments, the appearance information may include at least one of the vehicle's exterior color and model.

[0108] In some embodiments, the first signal receiving module 104 can receive the third identity information and display the third identity information on a display device in the first vehicle. The third identity information can be displayed in the form of text information or audio or video information, and the corresponding display device can be the first display screen 1042 or the first voice prompt device 1043 in the first vehicle.

[0109] In some embodiments, the first display screen 1042 may be a vehicle-mounted display screen, and the first voice prompt component 1043 may be a speaker or a vehicle-mounted audio system.

[0110] In the embodiment of the present application, the third terminal carried in the third vehicle (or the second terminal carried in the second vehicle) may have the same or similar structure as the first terminal 01. Figure 3 The second terminal 02 (or third terminal) interacting with the first terminal 01 may include a second identity storage module 201, a second information collection module 202, a second processing module 203, a second signal receiving module 204, and a second signal sending module 205. The second identity storage module 201 may include a second shallow memory 2011 and a second deep memory 2012. The second information collection module 202 may include a second video collection component 2021, a second voice collection component 2022, a second pre-stored information storage component 2023, and a second touch screen 2024. The second signal receiving module 204 may include a second signal access selection component 2041, a second display screen 2042, and a second voice prompt component 2043. The second processing module 203 may be signal-connected to the second information collection module 202, the second identity storage module 201, the second signal sending module 205, and the second signal receiving module 204. The first signal sending module 105 of the first terminal 01 can be connected to the second signal receiving module 204 of the second terminal 02 through a wireless network, and the second signal sending module 205 of the second terminal 02 can be connected to the first signal receiving module 104 of the first terminal 01 through a wireless network.

[0111] Step 2024: In response to the input operation of the first user, obtain the updated end point.

[0112] In this step, after the first vehicle displays the third identity information, if the first user confirms that the third vehicle is not the second vehicle to be connected, they can re-enter trajectory information based on the original end point. This updated trajectory information may include the updated end point. In other words, this input operation can be used to indicate that the third vehicle is different from the second vehicle, and this input operation updates the trajectory information with the end point as the origin. Based on this updated trajectory information, the first processing module 103 can obtain the updated end point and then re-determine the position of the second vehicle.

[0113] In some embodiments, to distinguish between the first user's operation of updating trajectory information and the operation of initially inputting trajectory information, the distance between the origin (i.e., the starting point) of the updated trajectory information and the ending point of the previously input trajectory information can be detected. When the two coincide, the user's current input operation is considered to be an operation of updating the trajectory information, and the second vehicle can be determined based on the starting point, the ending point, and the updated ending point. When the distance between the origin of the updated trajectory information and the ending point of the previously input trajectory information exceeds a set distance threshold, the user's current input operation can be considered to be an operation of re-entering the trajectory information, and the second vehicle can be determined based on the starting point and ending point of the re-entered trajectory information based on steps 2021 to 2022 above.

[0114] In other embodiments, the time interval between the origin (i.e., the starting point) of the updated trajectory information and the end point of the previous input trajectory information can also be detected. When the time interval is less than a set time threshold, the user's current input operation can be considered an operation to update the trajectory information; when the time interval exceeds the set time threshold, the user's current input operation can be considered an operation to re-enter the trajectory information.

[0115] In the embodiment of the present application, the operation of updating the trajectory information by the first user may be an input operation performed when the first user's finger has not left the first touch screen 1024 after the first user previously input trajectory information. In some embodiments, the situation where the finger has not left the first touch screen 1024 may be a situation where the origin of the updated trajectory information coincides with the end point of the previously input trajectory information, and the time interval between the origin of the updated trajectory information and the end point of the previously input trajectory information is less than a set time threshold.

[0116] In an embodiment of the present application, after the first vehicle receives and displays the third identity information sent by the third vehicle, if the user does not perform an input operation pointing to the above-mentioned update trajectory information within a period of time, it can be considered that the currently determined third vehicle is the second vehicle to be connected, and then the following step 103 can be directly executed.

[0117] In other words, the first vehicle may execute step 103 described below in response to the first user's confirmation operation. The confirmation operation is used to indicate that the third vehicle is the second vehicle to be connected, and the confirmation operation may be the failure to perform the aforementioned input operation within a time period set by the first user, or the confirmation operation may be a click operation on the first signal access selection element 1041, which may be displayed on the first display screen 1042.

[0118] In some embodiments, the first signal access selection component 1041 may be a vehicle-mounted display screen or a button.

[0119] Step 2025: Determine the second vehicle based on the starting point, the ending point, and the updated ending point.

[0120] The trajectory information previously input by the first user indicates, to a certain extent, the positional relationship between the first vehicle and the second vehicle to be connected, and the updated trajectory information input again by the first user can be considered as a correction of the first input trajectory information. The position of the second vehicle to be connected is re-determined based on the trajectory information previously input. Therefore, the second vehicle to be connected can be determined by combining the starting point and ending point in the previously input trajectory information and the updated ending point in the updated trajectory information.

[0121] In some embodiments, the first processing module 103 may determine the position of the second vehicle based on the previously input trajectory information and the updated trajectory information, so as to control the first signal sending module 105 to send the first communication information to the second signal receiving module 204 of the second vehicle.

[0122] In some embodiments, step 2025 may be implemented in the following manner:

[0123] A first trajectory direction is determined based on the starting point and the updated ending point, where the first trajectory direction is the direction from the starting point to the updated ending point; a second trajectory direction is determined based on the ending point and the updated ending point, where the second trajectory direction is the direction from the ending point to the updated ending point; the first trajectory direction is mapped with the position of the first vehicle as the origin, and the second trajectory direction is mapped with the position of the third vehicle indicated by the ending point as the origin, and the vehicle at the intersection of the first trajectory direction and the second trajectory direction and closest to the first vehicle and the third vehicle is determined as the second vehicle.

[0124] The first track direction determined based on the starting point and the updated ending point can indicate the location of the vehicle to be connected. The ending point previously input by the first user can serve as a reference point for adjusting the track information by the first user. The second track direction determined based on this ending point and the updated ending point can assist in determining the location of the second vehicle newly determined by the first user.

[0125] In some embodiments, the updated end point may be aligned with the starting point and the end point, so that the first and second trajectory directions may partially overlap. In this case, the vehicle closest to the first and third vehicles in the overlapping portion is determined as the second vehicle. Alternatively, the updated end point may not be aligned with the starting point and the end point, so that the first and second trajectory directions may intersect at a certain angle. In this case, the intersection of the first and second trajectory directions can be determined, and the vehicle near this intersection and closest to the first and third vehicles is determined as the second vehicle.

[0126] It should be noted that due to factors such as calculation errors and user input errors, the second vehicle to be connected may not be exactly at the intersection of the first trajectory direction and the second trajectory direction. Therefore, after determining the intersection of the first trajectory direction and the second trajectory direction, vehicles can be detected within a certain range, and the vehicle closest to the first vehicle and the third vehicle within the set range can be determined as the second vehicle.

[0127] In some embodiments, the first trajectory direction and the second trajectory direction can be determined by the first processing module 103, and the vehicle at the intersection of the first trajectory direction and the second trajectory direction and closest to the first vehicle and the third vehicle can be determined as the second vehicle, so as to control the first signal sending module 105 to communicate with the second vehicle.

[0128] The above-mentioned method of determining the second vehicle from step 2023 to step 2025 can be applied to the situation where there are other vehicles between the first vehicle and the second vehicle, so that the second vehicle to be connected is determined with the middle vehicle (i.e., the third vehicle) as a reference point to improve the accuracy of determining the second vehicle to be connected.

[0129] Step 103: Send the first communication information to the second vehicle.

[0130] The first communication information may include first identity information and first interaction information. The first identity information may be displayed on the second vehicle before the first interaction information, and the first identity information is used for the second user to determine whether to display the first interaction information. The second user is located in the second vehicle. The first identity information may include appearance information of the first vehicle, and the appearance information may include at least one of the appearance color and model of the first vehicle. In other embodiments, the first identity information may also include account information of the first user, such as the terminal name of the first user, the user contact information associated with the first terminal 01, etc. In the embodiment of the present application, the structure of the second terminal 02 is the same as that of the first terminal 01, and the first terminal 01 and the second terminal 02 can communicate via a wireless network.

[0131] In some embodiments, the appearance information of the first vehicle may be stored in the first shallow memory 1011 of the first terminal 01 , and the account information of the first user may be stored in the first deep memory 1012 of the first terminal 01 .

[0132] In some embodiments, see Figure 3 The second signal receiving module 204 of the second terminal 02 receives the first communication information, and the second user located in the second vehicle confirms the first identity information displayed on the display component in the second vehicle through the second signal access selection component 2041 to agree to communicate with the first vehicle; the second signal access selection component 2041 can send the confirmation operation obtained from the second user to the second processing module 203; the second processing module 203 controls the display component in the second vehicle to display the first interaction information.

[0133] In some embodiments, the confirmation operation may be a click operation on the second signal access selection element 2041 , and the second signal access selection element 2041 may be displayed on the second display screen 2042 .

[0134] In some embodiments, a first vehicle can transmit a first communication message to a second vehicle via the first signal transmission module 105 , wherein the first identity information allows the second user to confirm the identity of the first vehicle initiating the communication request. After confirming the identity of the first vehicle, the first interaction message transmitted by the first user enables the second user to obtain the content intended by the first user. The first identity information is displayed on the display unit of the second vehicle before the first interaction message, allowing the second user to first learn the identity information of the first vehicle. The first interaction message is then displayed on the display unit of the second vehicle after confirming the first identity information.

[0135] In some embodiments, when the first interaction information is voice information, a voice prompt can be given through the second voice prompt 2043 of the second terminal 02; when the first interaction information is text information or video information, it can be displayed through the second display screen 2042 of the second terminal 02.

[0136] In some embodiments, the second display screen 2042 may be a vehicle-mounted display screen, and the second voice prompt component 2043 may be a speaker or a vehicle-mounted audio system.

[0137] In some embodiments, the first interaction information may be pre-stored information in the first pre-stored information storage unit 1023, such as text information such as "your trunk is closed," "your tire is flat," or "please give way." The first interaction information may also be video information of the first user captured by the first video capture unit 1021 or voice information of the first user captured by the first voice capture unit 1022. Pre-stored text information, voice information, and video information facilitate user selection, avoid affecting the user's driving, and ensure driving safety.

[0138] For example, when the first user needs to overtake the second vehicle in front, the first interactive message can be used to convey the message of asking the second vehicle to give way, so that the vehicle can drive safely during driving and conduct short-distance temporary communication with the second vehicle without affecting driving, which greatly ensures driving safety and avoids collisions and congestion caused by forced overtaking.

[0139] For example, if a first user needs to alert a second user in a second vehicle that their tire is flat, they can send the first interactive message to alert the second user, allowing the second user to promptly be informed of the status of the second vehicle to avoid a traffic accident. Compared to vague prompts such as honking the horn and flashing the indicator light, this method can more accurately convey information to the second user, avoiding misunderstandings and unnecessary disputes.

[0140] In some embodiments, the first video acquisition component 1021 may be a camera.

[0141] In some embodiments, step 103 may be specifically implemented in the following manner: sending the first communication information to the second vehicle within the first signal transmission range.

[0142] Among them, the first signal transmission range is the range of a fan-shaped area with the position of the first vehicle as the center, the line between the first vehicle and the second vehicle as the radius, and the central angle as the set angle. The first signal transmission range can effectively ensure that the first signal sending module 105 can communicate with the second vehicle.

[0143] In some embodiments, the set angle may be 5 to 10 degrees.

[0144] The vehicle communication method provided in the embodiment of the present application determines the second vehicle to be connected and sends the first communication information to the second vehicle based on the trajectory information input by the first user, so that the communication connection between the vehicles can be established quickly and accurately based on the trajectory information input by the user, thereby improving the efficiency of information transmission between vehicles; in addition, the first communication information sent by the first vehicle to the second vehicle includes first identity information and first interaction information, wherein the first identity information is displayed on the second vehicle before the first interaction information, and the first identity information is used for the second user to determine whether to display the first interaction information, so that the second user in the second vehicle can determine whether to interact with the second vehicle based on the first identity information and then display the first interaction information, and send the identity information and interaction information to the second vehicle at the same time, further improving the efficiency of information transmission between vehicles.

[0145] It should be noted that in the embodiment of the present application, the first user can enable the first vehicle to determine the second vehicle to be connected by inputting trajectory information, and can send communication messages to the second vehicle. The operation is relatively simple and will not affect the first user's driving of the vehicle. Therefore, information interaction between vehicles can be realized quickly and accurately for moving vehicles.

[0146] In the above embodiment, the first vehicle is used as the requesting party for establishing communication. In other embodiments, the first vehicle may also be the receiving party for establishing communication, so that the first vehicle may also perform the steps performed by the second vehicle. In other words, see Figure 4 , the first vehicle may further perform the following steps:

[0147] Step 401: Receive second communication information sent by a second vehicle, where the second communication information includes second identity information and second interaction information.

[0148] Similar to the first identity information, the second identity information sent by the second vehicle to the first vehicle may include the second vehicle's appearance information, which may include at least one of the second vehicle's color and model. Alternatively, the second identity information may also include the second user's account information, such as the second user's terminal name and the user contact information associated with the second terminal 02.

[0149] In some embodiments, see Figure 3 , the appearance information of the second vehicle can be stored in the second shallow memory 2011 of the second terminal 02, and the account information of the second user can be stored in the second deep memory 2012 of the second terminal 02.

[0150] In some embodiments, the first vehicle may receive the second communication information sent by the second vehicle through the first signal receiving module 104 .

[0151] In an embodiment of the present application, the second vehicle is the requesting party for establishing communication. The user in the second vehicle can input trajectory information through the second touch screen 2024 and send the second communication information according to the embodiment in which the first vehicle is the requesting party for establishing communication.

[0152] Step 402: Display the second identity information.

[0153] The second identity information is received by the first signal receiving module 104 of the first terminal 01 , and the second identity information is displayed by the display element in the first vehicle, so that the first user knows the identity information of the second vehicle.

[0154] In some embodiments, the display element may be, for example, a first display screen 1042 or a first voice prompt element 1043 in the first vehicle. The first display screen 1042 may be an in-vehicle display screen for displaying text-based identity information; the first voice prompt element 1043 may be a speaker or in-vehicle audio system for displaying audio or video-based identity information.

[0155] Step 403: Display second interaction information in response to the first operation of the first user.

[0156] In the embodiment of the present application, after displaying the second identity information, the first vehicle may further display a confirmation prompt to the first user, which may be a text message, or an audio or video message. The first user may confirm or reject the confirmation prompt in response to the confirmation prompt.

[0157] In some embodiments, a first user located in the first vehicle can confirm the second identity information displayed on the display component in the first vehicle through the first signal access selection component 1041 to agree to communicate with the second vehicle; the first signal access selection component 1041 can send the confirmation operation obtained from the first user to the first processing module 103; the first processing module 103 controls the display component in the first vehicle to display the second interaction information.

[0158] In some embodiments, the second interaction information may be pre-stored information in the second pre-stored information storage element 2023, such as text information, voice information, or video information such as "Your trunk is not closed," "Your tire is flat," or "Please give way." The second interaction information may also be video information of the second user collected in real time by the second video capture element 2021. The second interaction information may also be voice information of the second user collected in real time by the second voice capture element 2022. Pre-stored text information, voice information, and video information facilitate user selection, avoid affecting the user's driving, and ensure driving safety.

[0159] In some embodiments, when the second interaction information is voice information, a voice prompt can be given through the second voice prompt component 2043; when the second interaction information is text information or video information, it can be displayed through the second display screen 2042.

[0160] The first operation is used to instruct the first user to confirm the communication connection between the first vehicle and the second vehicle. For example, the first vehicle may display a prompt box on an onboard display screen, which may display the question "Do you want to receive the corresponding interactive information?" and may include a "Yes" button and a "No" button. When the first user clicks the "Yes" button, it may be considered that the first operation has been performed.

[0161] In some embodiments, the first vehicle can receive the first operation of the first user through the first signal access selection component 1041, so that the first processing module 103 obtains the confirmation message input by the first user that the first vehicle and the second vehicle are communicating with each other; and displays the second interaction information through the display component of the first vehicle to enable the first user to know the interaction information of the second user.

[0162] In some embodiments, the first signal access selection component 1041 may be a vehicle-mounted display screen or a button.

[0163] Step 404 : In response to the second operation of the first user, a rejection message is sent to the second vehicle.

[0164] The second operation is used to instruct the first user to reject the communication connection between the first vehicle and the second vehicle. For example, when the first user clicks the "No" button, it can be considered that the second operation is performed.

[0165] In some embodiments, in response to the second operation of the first user, the first vehicle may send a rejection message to the second vehicle through the first processing module 103 .

[0166] In the vehicle communication method provided by the present application, the first vehicle acts as the receiving party for establishing communication, and simultaneously receives the second identity information and the second interaction information sent by the second vehicle, and displays the second identity information before the second interaction information, so that the first user can confirm whether to establish a communication connection with the second vehicle. If the first user confirms the communication connection between the first vehicle and the second vehicle, the received second interaction information can be directly displayed, thereby improving the efficiency of information transmission between vehicles.
