Example 1

The following describes in detail an information transfer method in the case of an abnormal radio signal, which is provided in the embodiments of the present application, with reference to the embodiments and the drawings.

Fig. 1 shows a schematic diagram of an information transmission method when a vehicle wireless signal is abnormal, and the following is a detailed description of the method steps of the present embodiment in conjunction with fig. 1.

specifically, real-time information of the vehicle (such as the geographic location of the vehicle, etc.),Vehicle conditions, road conditions, etc.) and record information of at least one geographical location where wireless signals are present during the vehicle trip. More specifically, the vehicle a searches for wireless signals in the journey and records the geographic positions of the target wireless signals in sequence if the vehicle is in the journey B₁、B₂、B₃If the wireless signal exists, recording B₁、B₂、B₃When the mobile equipment needs to be started to transmit the real-time information, the information can be transmitted accurately and directionally without blind search, and the timeliness and the accuracy are achieved.

S2: and determining that the vehicle needs to transmit the real-time information to the target object.

Preferably, a start instruction of the BCALL or ECALL function is acquired, and the vehicle is determined to need to transmit real-time information to the target object according to the start instruction;

specifically, in the present embodiment, the mobile device is placed in the vehicle and connected to the vehicle power source for charging, and when the mobile device is fully charged with sufficient power to perform the relevant work, the charging is stopped and the mobile device is parked in the vehicle without losing the vehicle power. When the vehicle meets an emergency and needs to send a distress signal to a target object (such as a rescue center, a background and the like), a user sends a start instruction of a BCALL or ECALL function (such as pressing a BCALL or ECALL key), and the start instruction can determine that the vehicle needs to transmit real-time information to the target object: if the wireless communication module of the vehicle can normally acquire the wireless signal at the moment, the wireless communication module can directly send real-time information such as the position, the state and the like of the vehicle to the target object, and under the condition, the movable equipment is in a dormant standby state; if the wireless communication module of the vehicle is abnormal and cannot acquire the wireless signal at this time, and the start instruction cannot start the BCALL or ECALL function of the vehicle, the mobile device may be started to assist in information transfer (such as seeking help to the outside). The "target object" herein is a receiver (such as a rescue center, a background, etc.) that is expected to acquire the real-time information, and the embodiment is not limited thereto.

Further, prior to sending the information delivery instruction to the removable device:

sending a wake-up instruction to the mobile device;

receiving a mark signal sent by the movable equipment within a first preset time sent by the awakening instruction;

the flag signal here is used to indicate that the removable device has been awakened and is in a normal operating mode.

Specifically, before sending an information transfer instruction to the mobile device to instruct it to perform information transfer, it is necessary to ensure that the mobile device is in a normal state and that its communication connection with the vehicle is normal. To this end, first, a wake-up command is issued to the removable device to activate it from the hibernation state; then, within a first preset time of sending the wake-up command, if a flag signal (such as a flash of an operation mode indicator lamp of the mobile device) sent by the mobile device is received, it indicates that the mobile device has been woken up and is in a normal operation mode, and therefore, an information transfer command can be sent to the mobile device to indicate the mobile device to perform information transfer. The form of the mark signal sent by the mobile device and the corresponding meaning thereof can be set in advance, and this embodiment does not limit this.

Preferably, the vehicle communicates with the mobile device through WiFi signals or radio signals of a preset frequency band, and further, the mobile device is a mobile terminal or a drone.

It should be noted that the present embodiment does not limit the manner of wireless communication between the vehicle and the mobile device, the type of the mobile device, and the moving manner of the mobile device. But preferably, here, the vehicle can communicate with the mobile device through WiFi signals or radio signals of preset frequency bands, and the mobile device is a drone or a mobile device. More specifically, when the mobile device is an unmanned aerial vehicle, the mobile device can communicate with the vehicle through a WiFi signal and also communicate with the vehicle through a radio signal in a preset frequency band, at present, the 840.5-845MHz, 1430-plus-1444 MHz, and 2408-plus-2440 MHz frequency bands specified by the ministry of industry and communications in China are used for the unmanned aircraft system, so when the mobile device is an unmanned aerial vehicle, the preset frequency bands can be 840.5-845MHz, 1430-plus-1444 MHz, and 2408-plus-2440 MHz frequency bands.

Fig. 2 is a schematic diagram illustrating a device structure of a vehicle wireless communication system to which an information transmission method in vehicle wireless signal abnormality is applied according to the present embodiment. As shown in fig. 2, an Electronic Control Unit (ECU) of the vehicle a includes a Micro Control Unit (MCU), a Micro Processing Unit (MPU), a wireless communication module, and the like, and a removable device is carried in the vehicle, and the device is provided with a wireless communication module to realize a wireless communication function (such as GSM, GPRS, LTE, NR, V2X, and the like). It should be noted that the mobile device herein may be an unmanned aerial vehicle, a mobile device, etc., and this embodiment does not limit this.

determining a geographical position with the shortest straight-line distance between the geographical position and the current position of the vehicle from the at least one geographical position, and recording as a preset geographical position;

judging the size relation between the shortest straight line distance and a preset communication distance threshold value;

if the shortest straight line distance is not greater than a preset communication distance threshold value;

the information transfer instruction is used for instructing the movable equipment to move to the at least one geographic position, and comprises the following steps: the information transmission instruction is used for indicating the movable equipment to move to the preset geographic position;

the preset communication distance threshold herein refers to the longest straight-line distance between the vehicle and the movable device that can communicate by wireless signals.

Specifically, the geographic position with the shortest straight-line distance to the current position of the vehicle a is determined from at least one geographic position recorded in the vehicle journey where the target wireless signal exists, and is recorded as a preset valueA geographic location. More specifically, it is assumed that, as before, the vehicle a is located at a, where the geographical position of the presence of the wireless signal recorded during the journey is B, and information is to be transmitted₁、B₂、B₃Then calculate A and B separately₁、B₂、B₃Linear distance gamma therebetween₁、γ₂、γ₃And comparing gamma₁、γ₂、γ₃The minimum value of the three is the shortest straight line distance, and the gamma in the three is assumed₂At a minimum, therefore B₂The geographical position is the geographical position with the straight line distance between the vehicle a and the position A as the shortest straight line distance, namely the preset geographical position.

And judging the size relation between the obtained shortest straight line distance and a preset communication distance threshold. Assuming that the longest straight-line distance between the vehicle a and the mobile device that can communicate through the wireless signal is K (i.e., K is the preset communication distance threshold), that is, the mobile device starts to move from the current position a of the vehicle a to the position B, when the straight-line distance γ between a and B is less than or equal to K, the vehicle a can communicate with the mobile device through the wireless signal. More specifically, as previously assumed, i.e. comparing γ₂With the magnitude of K and determining gamma₂If K is less than or equal to K.

Furthermore, if the shortest straight-line distance is not greater than the preset communication distance threshold, the transmission instruction is used for indicating the movable equipment to return a notification message after moving to the preset geographic position;

after receiving the notification message, transmitting real-time information to the target object through the movable equipment;

the notification message here is used to indicate that the mobile device has reached the predetermined geographical location.

Specifically, if γ is assumed as before₂K is less than or equal to K, the movable equipment moves to B₂After the position is reached, a notification message is returned to prompt that the position reaches a preset position; and after receiving the notification message returned by the movable equipment, sending real-time information to the target object through the movable equipment.

More specifically, the mobile device moves to a preset geographic location (i.e., B)₂Where) and obtain the target wireless signal and return a notification message to indicate that it has reached a preset geographic location and can deliver real-time information, at which time:

application scenario a 1:

if the movable equipment and the vehicle can communicate through WiFi signals, the movable equipment sends hotspot signals to the vehicle, and the vehicle directly transmits the real-time information to the target object through the acquired hotspot signals after receiving a notification message returned by the movable equipment; in this scenario, the mobile device may be used as a transceiver or an enhancement device for a target wireless signal (i.e. a cellular signal) at the preset geographic location, and may receive the target wireless signal at the preset geographic location and send it to the vehicle directly or after enhancement.

Application scenario a 2:

if the movable equipment and the vehicle can communicate through the radio signal of the preset frequency band, the vehicle transmits the real-time information to the movable equipment through the radio signal after receiving a notification message returned by the movable equipment, and the movable equipment transmits the acquired real-time information to a target object; in such a scenario, the mobile device serves as a relay point for information transmission between the vehicle and the target object, and transmits real-time information acquired from the vehicle to the target object through a target wireless signal at a preset position.

Preferably, if the shortest straight-line distance is greater than the preset communication distance threshold, the information transmission instruction further includes real-time information and is used for instructing the mobile device to send the real-time information to the target object by using a target wireless signal at the preset geographic location after moving to the preset geographic location.

Specifically, if γ is assumed as before₂>K, when the mobile device moves to the preset geographic position (namely B)₂Where it cannot communicate with vehicle a via wireless signals, the message delivery instruction includes not only an instruction to move the mobile device to a predetermined geographic location (i.e., B)₂At) and also includes real-time information of the aforementioned vehicle. In such a scenario, the instruction may instruct the mobile device to move to a predetermined geographic location(i.e. B)₂Station) and then transmits the real-time information of the vehicle to the target object by using the target wireless signal at the station.

Preferably, after sending the information transfer instruction to the removable device:

if the movable equipment moves to the at least one geographical position when the actual linear distance is smaller than the early warning communication distance threshold value, real-time information is sent to the target object through the movable equipment; or,

if the movable equipment does not move to the at least one geographical position when the actual linear distance reaches the early warning communication distance threshold value, sending real-time information to the movable equipment so that the equipment can transmit the real-time information to the target object through a target wireless signal existing at the geographical position when moving to the at least one geographical position;

the preset communication distance threshold value is the longest straight-line distance between the vehicle and the mobile device, wherein the longest straight-line distance can be communicated through wireless signals, and the early warning communication distance threshold value is smaller than the preset communication distance threshold value.

Specifically, assume that the mobile device is located at the geographic location in real time B '(notably, the geographic location in real time B' is a variable geographic location) from the location of the vehicle a (i.e., a) to the at least one geographic location (i.e., B)₁、B₂、B₃Any geographical location) is monitored in real time, i.e. the straight-line distance β between the geographical locations a and B' is monitored in real time.

If β < k (i.e., the alert communication distance threshold), the mobile device has moved to the at least one geographic location (i.e., B)₁、B₂、B₃Any geographic location), the mobile device may communicate with the vehicle via wireless signals since the linear distance between the mobile device and the vehicle is still less than the preset communication distance threshold K at that time.

More specifically, the mobile device moves to the at least one geographic location (i.e., B)₁、B₂、B₃Any geographical location), and upon receipt of the alert message, transmitting real-time information to the target object via the mobile device, where the alert message is used to alert the mobile device that the at least one geographical location (i.e., B) has been reached₁、B₂、B₃Any geographic location), at which time:

application scenario b 1:

if the movable equipment and the vehicle can communicate through WiFi signals, the movable equipment sends hotspot signals to the vehicle, and the vehicle directly transmits the real-time information to the target object through the acquired hotspot signals after receiving a prompt message returned by the movable equipment; in this scenario, the mobile device serves as the at least one geographic location (i.e., B)₁、B₂、B₃Any geographical location) and can receive the target wireless signal (i.e., cellular signal) at the preset geographical location and directly transmit or enhance the target wireless signal to the vehicle.

Application scenario b 2:

if the mobile equipment and the vehicle can communicate through the radio signal of the preset frequency band, the vehicle sends the real-time information to the mobile equipment through the radio signal after receiving a prompt message returned by the mobile equipment, and the mobile equipment transmits the acquired real-time information to a target object; in this scenario, the mobile device acts as a relay point for information transfer between the vehicle and the target object, and the real-time information obtained from the vehicle is passed through the at least one geographic location (i.e., B)₁、B₂、B₃Any geographic location) to the target object.

If β = k (early warning communication distance threshold), the mobile device has not moved to the at least one geographic location (i.e., B)₁、B₂、B₃Any one geographic location), then real-time information of the vehicle is sent to the mobile device so that the device is moving to the at least one geographic location (i.e., B)₁、B₂、B₃Any geography ofLocation) and then may send real-time information to the target object via the target wireless signal at the geographic location.

Here, the early warning communication distance threshold K is smaller than the preset communication distance threshold K.

Specifically, when the wireless communication module of the vehicle sends an information transfer instruction to the movable device due to the abnormality of the wireless signal at the current position, the information transfer instruction is used for instructing the movable device to move to the at least one geographic position (i.e. B)₁、B₂、B₃Any one of the geographic locations) so that the mobile device begins moving to the at least one geographic location (i.e., B)₁、B₂、B₃Any geographic location) does not carry real-time information about the vehicle. The early warning communication distance threshold K is a reminding threshold, and the real-time information of the vehicle can not be acquired because the mobile equipment can not be in wireless communication with the vehicle after the real linear distance beta between the mobile equipment and the vehicle is larger than the preset communication distance threshold K by monitoring the real linear distance beta of the mobile equipment in real time. More specifically, when the actual linear distance β = K to the mobile device is monitored, the real-time information of the vehicle is sent to the device, thereby ensuring that the real-time information of the vehicle can be delivered even if it cannot be wirelessly communicated with the vehicle any more after the actual linear distance β of the mobile device is greater than a preset communication distance threshold K.

Preferably, the aforementioned information transfer instruction is further configured to:

instructing the mobile device to search for other wireless signals while moving to the at least one geographic location;

if the V2X communication module is not installed in the mobile device and the other wireless signals it searches for are cellular signals, or if the V2X communication module is installed in the mobile device and the other wireless signals it searches for are cellular signals, the mobile device is instructed to transmit the vehicle real-time information at the effective geographic location (assumed to be C) where the cellular signals are searched.

In particular, the following application scenarios exist:

application scenario c 1:

before sending an information transmission instruction to the movable equipment, determining a geographical position with the shortest straight-line distance between the geographical position and the current position of the vehicle from the at least one geographical position, and recording as a preset geographical position;

when the shortest straight-line distance is greater than a preset communication distance threshold value, the information transmission instruction further comprises real-time information and is used for indicating the movable equipment to search other wireless signals in the process of moving to a preset geographic position;

if the V2X communication module is not arranged in the movable equipment and other searched wireless signals are cellular signals, or if the V2X communication module is arranged in the movable equipment and other searched wireless signals are cellular signals, the movable equipment is instructed to transmit the real-time information of the vehicle at the effective geographic position where the cellular signals are searched;

the preset communication distance threshold is the longest straight-line distance between the vehicle and the mobile device, which can be used for communication through wireless signals, and the effective geographic position is the geographic position where the mobile device searches for cellular signals.

More specifically, it is assumed that, before sending the information delivery command to the mobile device, the information is sent from the at least one geographical location (B)₁、B₂、B₃) The geographical position with the straight-line distance between the geographical position and the current position of the vehicle as the shortest straight-line distance is determined and recorded as a preset geographical position (assumed as B)₂A straight-line distance of gamma from the current position of the vehicle₂) At this time, γ₂>K. Due to gamma₂>K, the information transmission command comprises real-time information of the vehicle and is used for indicating that the movable equipment is moving to the B₂And searching other wireless signals in the moving process, and if the mobile equipment searches other wireless signals at the position C and the wireless signals are cellular signals, transmitting the real-time information of the vehicle to the target object through the cellular signals at the position C.

Application scenario c 2:

after sending an information transfer instruction to the movable equipment, monitoring the actual linear distance between the vehicle and the movable equipment in real time;

and if the movable equipment does not move to the at least one geographic position and does not search for other wireless signals when the actual straight-line distance reaches the early warning communication distance threshold value, sending real-time information to the movable equipment so that the equipment can transfer the real-time information to the target object through a target wireless signal existing at the geographic position when moving to the at least one geographic position, or so that the equipment can transfer the real-time information to the target object through a cellular signal existing at the geographic position at the effective geographic position where the cellular signal is searched.

The preset communication distance threshold value is the longest straight-line distance between the vehicle and the mobile equipment, which can be communicated through wireless signals, the early warning communication distance threshold value is smaller than the preset communication distance threshold value, and the effective geographic position is the geographic position of the mobile equipment, which searches the cellular signals.

More specifically, as previously assumed, the information transfer instructions are for instructing the movable apparatus to be in at least one of the aforementioned geographic locations (B)₁、B₂、B₃) Searching other wireless signals in the moving process; after the information transmission instruction is sent, monitoring the actual linear distance between the vehicle and the movable equipment in real time in the moving process of the movable equipment; if when β = k, the mobile device has not moved to B yet₁、B₂、B₃At any location and no other wireless signals are searched, real-time information is sent to the mobile device. Thereafter, the mobile device moves to B₁、B₂、B₃When any position moves, other wireless signals are continuously searched if the position moves to B₁、B₂、B₃In the process of moving any position, cellular signals are searched at the effective geographic position C, and then real-time information is transmitted to the target object through the cellular signals existing at the position C;if the device is moved until it moves to B₁、B₂、B₃When no other wireless signal is searched at any position, B is passed₁、B₂、B₃Cellular signals present at any one location convey real-time information to the target object.

If the V2X communication module is arranged in the mobile equipment and other searched wireless signals are V2X signals, identity matching authentication is carried out to carry out V2X communication;

if the identity matching authentication is successful, the mobile device is instructed to conduct V2X communication at the target geographic location where the V2X signal was searched, so that the vehicle sends real-time information to the target object through the V2X signal via the mobile device.

The V2X communication is a vehicular wireless communication technology (V2X), which refers to a new generation of information communication technology for connecting a Vehicle with Everything, wherein V represents a Vehicle, 2 represents to, X represents any object interacting with the Vehicle, and V2X enables the Vehicle, road, people and network to be interconnected and intercommunicated, thereby greatly improving the safety and efficiency of road traffic.
