Description

Technical Field

[0001] The present invention relates to the technical field of multi-vehicle interaction, and specifically provides a method for multi-vehicle interaction. Background Art

[0002] Multi-vehicle interaction generally refers to a vehicle-road collaborative system, that is, a road traffic system that is safe, efficient, and environmentally friendly by using advanced wireless communication and new-generation Internet technologies to comprehensively implement dynamic real-time information interaction between vehicles and between vehicles and roads.

[0003] The vehicle-road collaborative system realizes dynamic real-time information interaction between vehicles and between vehicles and roads through comprehensive wireless communication and new-generation Internet technologies. This interaction is based on the collection and fusion of full-time and full-space dynamic traffic information, and further conducts active vehicle safety control and road collaborative management.

[0004] Currently, the vehicles running on the road have no social interaction. When a vehicle is in a congested section and needs to stop for a long time, or when an accident occurs on the section and the vehicle needs to stop for a long time, the driver is usually very bored and unable to understand the situation of the drivers in nearby vehicles, which may lead to the driver being in a poor mental state. Therefore, a method for multi-vehicle interaction is proposed to solve the above problems. Summary of the Invention

[0005] (1) Technical Problems to be Solved

When a vehicle is in a congested section and needs to stop for a long time, or when an accident occurs on the section and the vehicle needs to stop for a long time, the driver is usually very bored and unable to understand the situation of the drivers in nearby vehicles, which may lead to the driver being in a poor mental state.

[0007] (2) Technical Solutions

[0008] To achieve the above object of better passing the time through human-computer interaction and keeping the driver in a good mental state, the present invention provides the following technical solution: A method for multi-vehicle interaction, comprising the following steps:

[0009] Step 1: Receiving satellite positioning signals. The vehicle navigation system is built-in with a GPS receiver and can receive signals from at least four satellites;

[0010] Step 2: The vehicle navigation system uses triangulation or a similar method to calculate the precise coordinates of the vehicle on the earth based on the received satellite signals and distance information;

[0011] Step 3: In the in-vehicle HMI display screen, the navigation system constructs a virtual entertainment interface based on the vehicle position and map data. The virtual entertainment interface usually includes information such as the current position coordinates of the vehicle, driving direction, speed, virtual character image, etc.;

[0012] Step 4: Determine the gear of the vehicle. When the vehicle is stationary or moving slowly, the user switches the page through voice and switches the page to the entertainment interface;

[0013] Step 5: Scan for nearby Bluetooth devices and record the geographical location data and time at the time of scanning, and filter out mobile communication devices with a Bluetooth signal strength lower than the set value;

[0017] Step 9: After the images of both parties or multiple parties are created, chat or game interaction can be carried out through the 3D virtual image at this time, so as to achieve multi-vehicle interaction;

[0018] Step 10: The vehicle owner can move his own image to any position. If it moves to the position of another vehicle, then after the body display screen of the other vehicle agrees, the image of the current vehicle owner can be displayed.

[0020] Preferably, the triangulation method can calculate the accurate coordinates of the vehicle, including longitude, latitude, altitude, etc.

[0021] Preferably, the vehicle operating system also needs to obtain other relevant data, such as inertial information such as the attitude, speed, and acceleration of the vehicle.

[0035] Figure 2 It is a schematic diagram of page switching of the present invention. Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figure 1-2, A method for multi-vehicle interaction, including the following steps:

[0038] Step 1: Receiving satellite positioning signals. The vehicle navigation system is equipped with a GPS receiver and can receive signals from at least four satellites.

[0039] Step 2: The vehicle navigation system uses triangulation or a similar method to calculate the precise coordinates of the vehicle on the earth based on the received satellite signals and distance information.

[0040] Step 3: In the in-vehicle HMI display screen, the navigation system constructs a virtual entertainment interface based on the vehicle's position and map data. The virtual entertainment interface usually includes information such as the vehicle's current position coordinates, driving direction, speed, virtual character image, etc.

[0041] Step 4: Determine the gear of the normally driving vehicle. When the vehicle is stationary or driving slowly, the user switches the page through voice and switches the page to the entertainment interface.

[0042] Step 5: Scan for nearby Bluetooth devices and record the geographical location data and time at the time of scanning, and filter out mobile communication devices with a Bluetooth signal strength lower than the set value.

[0043] Step 6: When other devices are scanned, sort and display the scanned devices according to the strength of the Bluetooth signal.

[0044] Step 7: The owner of this vehicle can select one or more of them to send a friend addition request.

[0045] Step 8: When the friend addition request is approved, the vehicle connects to the virtual entertainment interface and transmits its own coordinates and image to the current vehicle through the network. After the current vehicle receives the data, it creates the given image of the other party at the coordinates of the other party.

[0046] Step 9: After the images of both parties or multiple parties are created, chat or game interactions can be carried out through 3D virtual images at this time, so as to achieve multi-vehicle interaction.

[0047] Step 10: The vehicle owner can move his own image to any position. If it moves to the position of another vehicle, then after the body display screen of the other vehicle agrees, the image of the current vehicle owner can be displayed.

[0048] In Figure 1 and Figure 2 In, in Step 1, the Beidou positioning system can also be used. The satellite signal contains a timestamp and satellite position information, and the receiver calculates the distance from each satellite by measuring the signal propagation time.

[0049] Specifically, through the satellite navigation system, the position of the vehicle can be accurately determined, facilitating the mapping of the vehicle's coordinates on the virtual entertainment interface and enabling the distance between vehicles to be judged based on the coordinates during multi-vehicle interaction.

[0050] In Figure 1 and Figure 2 triangulation can calculate the precise coordinates of the vehicle, including longitude, latitude, altitude, etc.

[0051] Specifically, the GPS positioning system accurately locates the vehicle's position through triangulation by receiving signals from four satellites. In environments with weak signals such as urban canyons or tunnels, the accuracy of GPS positioning may decrease. In such cases, geomagnetic direction sensors, gyro sensors, speed sensors, etc. that may be equipped on the vehicle can be used to assist in measuring the vehicle's driving trajectory and direction, thereby ensuring more accurate positioning.

[0052] In Figure 1 and Figure 2 the vehicle operating system also needs to obtain other relevant data, such as inertial information about the vehicle's attitude, speed, acceleration, etc. This is usually obtained through an inertial navigation system (INS). The data from satellite positioning and the inertial navigation system are fused to correct inertial deviations and obtain more accurate vehicle pose information.

[0053] Specifically, through the joint cooperation of the inertial navigation system and the GPS navigation system, more accurate positioning of the vehicle, road, building, etc. can be achieved, which not only makes multi-vehicle interaction more efficient but also ensures better navigation effects during normal vehicle driving.

[0054] In Figure 1 and Figure 2 the navigation system has detailed electronic map data built-in, including road information, landmarks, buildings, etc. The calculated vehicle position is compared with the map data to determine the vehicle's exact position on the map.

[0055] In Figure 1 and Figure 2 the construction of the virtual character image also includes:

[0056] Performing 2D character design, 3D character modeling, and rendering on the virtual entertainment interface, and enabling the character to move through skeletal animation.

[0057] Specifically, skeletal animation, also known as skeleton animation, is a computer animation technology that divides a three-dimensional model into two parts: a skin used to draw the model and a skeleton used to control the action. The character's running, walking, standing and other actions are usually achieved through skeletal animation in the model file. The weight of skeletal animation can be adjusted to make the transition between animations more natural. The character image constructed through skeletal animation is embedded in the virtual entertainment interface, which facilitates human-computer interaction and multi-vehicle interaction, effectively avoiding privacy leakage while increasing fun.

[0058] exist Figure 1 and Figure 2 In step 4, the judgment of page switching also includes the following steps:

[0059] Step 1: First determine whether the vehicle has stayed in P or N gear for more than 15 seconds;

[0060] Step 2: If the answer is yes, the owner is considered to be in a resting state, and the virtual entertainment interface can be awakened by voice;

[0061] Step 3: If no, the display remains in the navigation interface and cannot be exited.

[0062] Specifically, by judging the driving status, it can prevent users from switching interfaces due to accidental touches during normal driving, thereby affecting the navigation's broadcast and warnings on the normal driving route, thereby ensuring the safety of vehicle driving. In addition, when the friend's request to add is agreed, the vehicle is connected to the virtual entertainment interface and transmits its own coordinates and image through the network to the current vehicle. After receiving the data, the current vehicle creates the image given by the other party at the other party's coordinates. By setting the friend adding pre-procedure, the driver's privacy and personal wishes are fully respected.

[0063] exist Figure 1 and Figure 2 In the navigation system, the navigation system can also provide route planning, turn-by-turn voice prompts, estimated arrival time and other navigation services to ensure safety and convenience during driving.

[0064] In addition, the virtual entertainment interface is used when the vehicle is stationary or driving slowly, and the user can choose whether to use it.

[0065] In summary, the method for multi-vehicle interaction, the method for multi-vehicle interaction, through steps one to ten, builds a virtual entertainment interface and a virtual image of a character based on the navigation and positioning system, realizes human-vehicle interaction and multi-vehicle interaction, avoids long-term parking that makes the driver bored and in poor spirits, improves multi-vehicle interactivity, makes the journey more interesting and social, and solves the problem that there is no social interaction on the road now. When a vehicle is in a congested section and needs to stop for a long time, or an unexpected situation occurs on the section and needs to stop for a long time, the driver is usually very bored and cannot understand the situation of the drivers of nearby vehicles, which leads to the problem of the driver being in poor spirits.

[0066] Furthermore, the satellite positioning signal is first received, and the car navigation system uses triangulation or a similar method to calculate the precise coordinates of the vehicle on the earth based on the received satellite signal and distance information, and imports the coordinates and the character's virtual image into the virtual entertainment interface. When the vehicle is stationary or moving slowly, the user activates the virtual entertainment interface, and identifies nearby vehicles through the Bluetooth device, so that nearby vehicles that agree to the interface are also connected to the virtual entertainment interface, thereby achieving multi-vehicle interaction and increasing the fun of the journey, thus solving the problem of no social interaction on the road. When a vehicle is in a congested section and needs to stop for a long time, or an unexpected situation occurs on the section and needs to stop for a long time, the driver is usually very bored and cannot understand the situation of the drivers of nearby vehicles, which leads to the problem of poor mental state of the driver.
