Vehicle location tracking system and vehicle using BLE module and UWB module in emergency situations

[0001] The present invention relates to a vehicle location tracking system and a vehicle using a BLE module and a UWB module in an emergency situation.

[0002] Modern vehicle location tracking systems primarily use GPS to determine vehicle location. However, GPS signals can be weakened in indoor parking lots and tunnels, making it difficult to quickly locate a vehicle in an emergency. Therefore, there is a pressing need for a system that can provide consistent location measurements both indoors and outdoors, and that can accurately determine vehicle location even in emergencies.

[0003] The present invention seeks to provide consistent position measurement anywhere, indoors or outdoors, since GPS signals become weak in indoor parking lots, tunnels, etc.

[0004] The present invention aims to accurately measure the location of a vehicle anywhere, indoors or outdoors, in an emergency situation, since GPS signals are weak in indoor parking lots, tunnels, etc.

[0005] The present invention relates to a vehicle whose location is tracked from a user terminal in an emergency, comprising: a control unit; a BLE module communicating with a BLE module of the user terminal; and a UWB module communicating with a UWB module of the user terminal; wherein, when an emergency rescue mode switching condition of the vehicle is satisfied, the control unit controls the vehicle to be switched from a normal mode to an emergency rescue mode, release BLE security of the BLE module, and controls the UWB module to transmit location information of the vehicle to the UWB module of the user terminal.

[0006] Additionally, the control unit controls the UWB module to perform a UWB session connection for rescue mode with the UWB module of the user terminal when the emergency rescue mode switching condition of the vehicle is satisfied.

[0007] In addition, the emergency rescue mode switching condition is any one of the operation of the impact sensor in the vehicle, the operation of the airbag of the vehicle, and the direct call of the driver of the vehicle.

[0008] Additionally, the control unit controls the shock sensor in the vehicle to operate when the sensitivity of the shock sensor is below a threshold value.

[0009] Additionally, the control unit controls equipment other than the minimum communication equipment to be switched to a low power mode when the emergency rescue mode switching condition of the vehicle is met.

[0010] The present invention relates to a user terminal for tracking the location of a vehicle in an emergency, comprising: a control unit; a BLE module for communicating with a BLE module of the vehicle; and a UWB module for communicating with a UWB module of the vehicle; wherein the BLE module receives an emergency rescue BLE signal when an emergency rescue mode switching condition of the vehicle is satisfied and the BLE module of the vehicle broadcasts an emergency rescue BLE signal; and the control unit executes a rescue mode in the user terminal when the BLE module receives the emergency rescue BLE signal, and the UWB module receives location information of the vehicle from the UWB module of the vehicle.

[0011] In addition, the emergency rescue mode switching condition is any one of the operation of the impact sensor in the vehicle, the operation of the airbag of the vehicle, and the direct call of the driver of the vehicle.

[0012] The present invention has the effect of quickly rescuing the occupants of a vehicle (100) in an emergency situation by determining the exact location of the vehicle (100) even in places such as indoor parking lots and tunnels where GPS signals are not received.

[0013] In addition, the present invention utilizes the low-power characteristics of the BLE module to increase battery efficiency compared to existing GPS receivers, thereby enabling the structure to be utilized for a long time.

[0017] Specific details of the embodiments are included in the detailed description and drawings.

[0018] The advantages and features of the present invention, and the methods for achieving them, will become clearer with reference to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below and may be implemented in various different forms. These embodiments are provided only to ensure that the disclosure of the present invention is complete and to fully inform those skilled in the art of the scope of the invention, and the present invention is defined only by the scope of the claims. Like reference numerals designate like elements throughout the specification.

[0019] Figure 1 is a drawing for explaining a vehicle location tracking system using existing GPS satellites.

[0020] As illustrated in Fig. 1, a vehicle location tracking system using an existing GPS satellite (300) is a system that calculates the distance between a GPS satellite (300) and a GPS signal receiver (not shown) of a vehicle (100) while the GPS satellite (300) orbits the Earth, obtains coordinate values, and transmits location data to the vehicle (100).

[0021] However, the existing vehicle location tracking system using GPS satellites (300) uses a method of estimating the current location of the GPS signal receiver (not shown) by correlating the location value before the GPS signal was cut off with the direction, speed, etc. of the GPS signal receiver (not shown) of the vehicle (100) in places where the GPS signal is weak, such as indoor parking lots, tunnels, etc. Therefore, there is a limitation in that the exact location of the vehicle (100) cannot be determined. In addition, the GPS signal receiver (not shown) of the vehicle (100) requires continuous power consumption to receive GPS signals from GPS satellites (300), and there is also a problem of reduced battery efficiency.

[0022] Accordingly, the present invention can accurately determine the location of a vehicle (100) even in places where GPS signals are not received, such as indoor parking lots and tunnels. Furthermore, the present invention can accurately determine the location of a vehicle (100) when conditions for switching to an emergency rescue mode for the vehicle (100) are met. Furthermore, the present invention utilizes the low-power characteristics of the BLE module, resulting in higher battery efficiency compared to existing GPS receivers.

[0023] FIG. 2 is a diagram showing the configuration of a vehicle and a user terminal of a vehicle location detection system utilizing a BLE module and a UWB module according to the present invention.

[0024] As illustrated in FIG. 2, the vehicle (100) includes a control unit (130), a BLE module (110), and a UWB module (120). In addition, the user terminal (200) includes a control unit (230), a BLE module (210), and a UWB module (220).

[0025] According to the present invention, the control unit (130) can switch the vehicle (100) from the normal mode to the emergency rescue mode when the emergency rescue mode switching condition of the vehicle (100) is satisfied. Specifically, the control unit (130) can switch the vehicle (100) from the normal mode to the emergency rescue mode by the operation of an impact sensor (not shown) within the vehicle (100). For example, when the vehicle (100) overturns in a tunnel due to an accident, the control unit (130) can switch the vehicle (100) from the normal mode to the emergency rescue mode by the operation of the impact sensor. However, the control unit (130) can control the operation of the impact sensor (not shown) within the vehicle (100) to be activated when the sensitivity of the impact sensor (not shown) is below a threshold value. For a specific example, the control unit (130) can control the sensitivity of the impact sensor (not shown) to be relatively low so that the vehicle (100) is not switched from the normal mode to the emergency rescue mode due to an impact from a speed bump, etc. In addition, the control unit (130) can control the sensitivity of the shock sensor (not shown) to be relatively low so that the vehicle (100) can be switched from a normal mode to an emergency rescue mode when the impact on the vehicle (100) is relatively large, such as a rear-end collision with another vehicle (100) or a rollover of the vehicle (100).

[0026] According to the present invention, a vehicle (100) including a BLE module (110) and a UWB module (120) may be a vehicle equipped with a digital key system, and the BLE module (110) and the UWB module (120) may be configured based on the digital key system of the vehicle (100), but are not limited thereto.

[0027] According to the present invention, when the emergency rescue mode switching condition of the vehicle (100) is satisfied, the control unit (130) can switch the vehicle (100) from the normal mode to the emergency rescue mode. When the vehicle (100) is switched to the emergency rescue mode, the control unit (130) can control to release the security of the BLE module (110) and control to broadcast the BLE signal for emergency rescue. In addition, the control unit (130) can control to switch the equipment other than the minimum communication equipment to the low power mode when the vehicle (100) is switched to the emergency rescue mode. For a specific example, the control unit (130) can control to switch the equipment other than the BLE module (110) and the UWB module (120) to the low power mode.

[0028] According to the present invention, the control unit (130) can control the UWB module (120) to perform a UWB Session connection for rescue mode with the UWB module (220) of the user terminal (200) when the vehicle (100) is switched to emergency rescue mode. Specifically, the UWB Session for rescue mode has the highest session priority, unlike the general UWB Session, and enables fast and accurate positioning by shortening the positioning cycle.

[0029] According to the present invention, when the vehicle (100) is switched to an emergency rescue mode, the control unit (130) can control the UWB module (120) to perform a UWB session connection for the rescue mode with the UWB module (220) of the user terminal (200), and accordingly, the control unit (130) can control the UWB module (120) to transmit location information of the vehicle (100) to the UWB module (220) of the user terminal (200).

[0030] According to the present invention, when the control unit (130) controls the UWB module (120) to transmit the location information of the vehicle (100) to the UWB module (220) of the user terminal (200), a current location user interface of the vehicle (100) can be provided on the display unit (not shown) of the user terminal (200), and accordingly, the user of the user terminal (200) can receive the current location information of the vehicle (100) in real time.

[0031] Here, the user terminal (200) refers to a user terminal (200) located outside the vehicle (100) whose location the vehicle (100) is to be tracked, rather than a user terminal of a passenger of the vehicle (100).

[0032] According to the present invention, a vehicle (100) including a BLE module (110) and a UWB module (120) may be a vehicle equipped with a digital key system, and the BLE module (110) and the UWB module (120) may be configured based on the digital key system of the vehicle (100), but are not limited thereto.

[0033] According to the present invention, a user terminal (200) for tracking the location of a vehicle (100) in an emergency situation includes a BLE module (210) that communicates with a BLE module (110) of the vehicle (100). Specifically, when an emergency rescue mode switching condition of the vehicle (100) is met and the BLE module (110) of the vehicle (100) broadcasts an emergency rescue BLE signal, the BLE module (210) can receive the broadcasted emergency rescue BLE signal.

[0034] According to the present invention, the user terminal (200) includes a control unit (230), and when the BLE module (210) receives a BLE signal for emergency rescue, the control unit (230) can execute a rescue mode in the user terminal (200). Accordingly, the BLE module (210) can be connected to the unlocked BLE module (110) of the vehicle (100) via BLE, and the UWB module (220) can be connected to the UWB module (120) of the vehicle (100) via a UWB Session for rescue mode. Specifically, the UWB Session for rescue mode has the highest session priority, unlike the general UWB Session, and shortens the positioning cycle to enable fast and accurate positioning.

[0035] According to the present invention, a vehicle (100) including a BLE module (110) and a UWB module (120) may be a vehicle equipped with a digital key system, and the BLE module (110) and the UWB module (120) may be configured based on the digital key system of the vehicle (100), but are not limited thereto.

[0036] FIG. 3 is a drawing for explaining a vehicle location tracking system using a BLE module and a UWB module in an emergency situation according to the present invention.

[0037] As illustrated in FIG. 3, an emergency situation may occur (S10) in a vehicle (100). For example, an emergency situation may occur (S10) in which the vehicle (100) overturns or an accident occurs, requiring an ambulance or rescue personnel to determine the location of the vehicle (100).

[0038] The present invention can accurately measure the current location of a vehicle (100) by utilizing a UWB module (120) when an emergency situation occurs (S10) in a vehicle (100) where a GPS satellite (300) cannot measure the exact current location of the vehicle (100), such as in a tunnel or an indoor parking lot.

[0039] According to the present invention, when an emergency situation occurs in a vehicle (100) (S10), the vehicle (100) can satisfy a predetermined emergency rescue mode switching condition set in advance in the vehicle (100) (S20). Specifically, the emergency rescue mode switching condition may be any one of the operation of an impact sensor within the vehicle (100), the operation of an airbag of the vehicle (100), and a direct call from the driver of the vehicle (100). However, the control unit (130) may control the operation of the impact sensor (not shown) within the vehicle (100) to be activated when the sensitivity of the impact sensor (not shown) is below a threshold value. For a specific example, the control unit (130) may control the sensitivity of the impact sensor (not shown) to be relatively low so that the vehicle (100) is not switched from a normal mode to an emergency rescue mode due to an impact from a speed bump, etc. In addition, the control unit (130) can control the sensitivity of the shock sensor (not shown) to be relatively low so that the vehicle (100) can be switched from a normal mode to an emergency rescue mode when the impact on the vehicle (100) is relatively large, such as a rear-end collision with another vehicle (100) or a rollover of the vehicle (100).

[0040] According to the present invention, when the vehicle (100) satisfies the emergency rescue mode switching condition (S20), the vehicle (100) can be switched to the emergency rescue mode (S30) by the control unit (130). At this time, the BLE security of the BLE module (110) can be released by the control unit (130), and accordingly, a third-party user terminal (200) can access the BLE module (110). In addition, equipment other than the minimum communication equipment can be switched to a low power mode by the control unit (130), so that the efficiency of the battery of the vehicle (100) can be increased. In addition, when the vehicle (100) is switched to the emergency rescue mode (S30), the BLE module (110) can broadcast a BLE signal for emergency rescue by the control unit (130). That is, the control unit (130) can control the BLE module (110) so that the BLE module (210) of the user terminal (200) can receive the BLE signal of the vehicle (100).

[0041] According to the present invention, when the BLE module (210) of the user terminal (200) receives a BLE signal of a vehicle (100) in emergency rescue mode (S40), the rescue mode can be executed (S50) by the control unit (230) in the user terminal (200). When the rescue mode is executed (S50) by the control unit (230) in the user terminal (200), the unlocked BLE module (110) of the vehicle (100) and the BLE module (210) of the user terminal (200) can be connected. In addition, when the rescue mode is executed (S50) by the control unit (230) in the user terminal (200), the UWB module (120) of the vehicle (100) and the UWB module (220) of the user terminal (200) can be connected. That is, the control unit (130) can control the UWB module (120) to perform a UWB Session connection for rescue mode with the UWB module (220) of the user terminal (200) when the vehicle (100) is switched to emergency rescue mode. Specifically, the UWB Session for rescue mode has the highest session priority, unlike the general UWB Session, and enables fast and accurate positioning by shortening the positioning cycle.

[0042] According to the present invention, when the control unit (130) controls the UWB module (120) to transmit the location information of the vehicle (100) to the UWB module (220) of the user terminal (200), a current location user interface of the vehicle (100) may be provided on the display unit (not shown) of the user terminal (200), and accordingly, the user terminal (200) may execute a structure (S80) based on the vehicle location. That is, the user of the user terminal (200) may be provided with the current location information of the vehicle (100) in real time. For a specific example, the user terminal (200) may receive information on the current location of the vehicle (100) in the form of a graphical user interface through the display unit (not shown).

[0043] The scope of the present invention is not limited to the embodiments described above, but can be implemented in various forms within the scope of the appended claims. It is contemplated that any person skilled in the art would be capable of making various modifications within the scope of the claims without departing from the spirit of the invention as claimed.
