[0042] Hereinafter, the operating principles and embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0043] Figure 1 is a control block diagram of a vehicle according to an embodiment of the present disclosure. Figure 2 is a plan view of a vehicle equipped with a UWB transceiver according to an embodiment of the present disclosure.

[0044] like Figure 1 and Figure 2 As shown, the vehicle 1 according to an embodiment of the present disclosure may include a controller that controls the plurality of ultra-wideband (UWB) transceivers to selectively operate in at least one of a first mode for communication and a second mode for detecting obstacles based on location information of the plurality of UWB transceivers and a mobile key with a built-in UWB function. Here, the vehicle 1 may include a plurality of UWB transceivers, and the mobile key may include a smart key.

[0045] Some of the plurality of UWB transceivers 100 may be installed inside the vehicle 1. For example, the plurality of UWB transceivers 100 installed inside the vehicle 1 may include a first UWB transceiver 201, a second UWB transceiver 202, and a third UWB transceiver 203.

[0046] Reference Figure 2 According to an embodiment of the present disclosure, the vehicle 1 includes a first UWB transceiver 201 installed around the passenger seat, a second UWB transceiver 202 and a third UWB transceiver 203 installed on the rear seats, but the installation position and number of the UWB transceiver 100 may vary depending on the performance of the UWB transceiver 100, the size and internal structure of the vehicle 1.

[0047] The remaining UWB transceivers 100 may be installed outside the vehicle 1. For example, the plurality of UWB transceivers 100 installed outside the vehicle 1 may include a fourth UWB transceiver 211, a fifth UWB transceiver 212, a sixth UWB transceiver 213, and a seventh UWB transceiver 214.

[0048] Reference Figure 2 According to an embodiment of the present disclosure, the vehicle 1 includes a sixth UWB transceiver 213 and a seventh UWB transceiver 214 installed around the headlights of the vehicle 1, and a fourth UWB transceiver 211 and a fifth UWB transceiver 212 installed around the taillights of the vehicle 1, but the installation position and number of the UWB transceiver 100 may vary depending on the performance of the UWB transceiver 100, the size and external structure of the vehicle 1.

[0049] The UWB transceiver 100 may include a transmitter 100a and a receiver 100b. The transmitter 100a may transmit a first UWB signal (hereinafter referred to as an "authentication signal") for communicating with a mobile key of the vehicle 1 and a second UWB signal (hereinafter referred to as a "detection signal") for detecting an object.

[0050] In this case, both the authentication signal and the detection signal can be signals generated based on the UWB pulse signal. Here, the authentication signal and the detection signal can be signals of different frequency bands and can be sent through different transmission channels.

[0051] The transmitter 100a may transmit the authentication signal in all directions, and may transmit the detection signal in a direction concentrated toward the detection area.

[0052] The receiver 100b may include a first antenna (not shown) capable of receiving an authentication signal transmitted from a mobile key of the vehicle 1. For example, the authentication signal transmitted from the mobile key may include a UWB signal, and the first antenna may include a UWB antenna. In more detail, the first antenna (not shown) may receive an authentication signal transmitted from a transponder of the mobile key.

[0053] The receiver 100b may include a second antenna (not shown) for receiving a detection signal reflected from an object when the detection signal transmitted from the transmitter 100a is reflected from the object. The second antenna may include a UWB antenna. In more detail, the second antenna (not shown) may receive a detection signal reflected from an object (hereinafter referred to as a "reflection signal").

[0054] The first antenna and the second antenna may be separately provided in the receiver 100 b , but may also be provided as one integrated antenna.

[0055] The UWB transceiver 100 may include a switching unit (not shown). The switching unit (not shown) may selectively employ the first antenna or the second antenna based on a control signal of the controller 110.

[0056] The mobile key is a device including a communication transceiver capable of transmitting an authentication signal corresponding to the vehicle 1, and may include a FOB key and / or a user terminal of the vehicle 1. The user terminal may be linked with the vehicle 1 through communication with the vehicle 1, and may include a portable terminal capable of accessing the vehicle 1 through a network. For example, the user terminal may include all types of handheld-based wireless communication devices such as smart phones and wearable devices such as watches, rings, bracelets, anklets, necklaces, glasses, contact lenses, or head mounted devices (HMD).

[0057] The controller 110 may obtain location information of the mobile-key using a time of flight (ToF) method with respect to an authentication signal received from a first antenna included in the receiver 100 b of the UWB transceiver 100 .

[0058] In addition, the controller 110 may obtain the location information of the mobile-key using a time of arrival (TOA), a time difference of arrival (TDOA), an angle of arrival (AOA), or a received signal strength indicator (RSSI) method.

[0059] In more detail, the controller 110 can determine not only the distance between the vehicle 1 and the mobile key, but also the precise location of the mobile key. For example, when the first antenna included in the receiver 100b of the three UWB transceivers 100 is used, the controller 110 can determine the distance between each UWB transceiver 100 and the mobile key based on the authentication signal received from each of the three receivers, and can obtain the precise location information of the mobile key based on the distance between each UWB transceiver 100 and the mobile key.

[0060] Hereinafter, a method for controlling multiple UWB transceivers 100 to operate in at least one of a first mode and a second mode based on location information of a mobile key will be described, wherein in the first mode, the controller 110 communicates with the mobile key based on an authentication signal sent from the mobile key, and the second mode is used to send a detection signal to an object and detect the object based on the detection signal reflected from the object.

[0061] When it is determined that the mobile key is located inside the vehicle 1 , the controller 110 may control the plurality of UWB transceivers 201 , 202 , and 203 installed inside the vehicle 1 such that the plurality of UWB transceivers 201 , 202 , and 203 operate in the first mode.

For example, the second mode may be a rear passenger alert (ROA) function, but is not limited thereto. In this case, the controller 110 may control the execution of the ROA function until it is determined that the mobile key is located within the communication range.

[0065] If it is determined that the mobile key is located outside the vehicle but within the communication range, the controller 110 may determine whether the mobile key is located within a predetermined distance relative to the tailgate of the vehicle 1 .

For example, the second mode may be to perform a parking assist system (PAS) function or a rear cross collision avoidance assist (RCCA) function, but is not limited thereto.

[0068] In more detail, the controller 110 may control to operate using the time division of the first mode and the second mode in any one of the plurality of UWB transceivers 211 , 212 , 213 , and 214 installed outside the vehicle 1 .

[0069] If it is determined that the mobile key is located within a predetermined distance relative to the tailgate of the vehicle 1, the controller 110 may control the plurality of UWB transceivers 201, 202, and 203 installed inside the vehicle 1 so that the plurality of UWB transceivers 201, 202, and 203 operate in the second mode. For example, the second mode may be a rear passenger alert (ROA) function. At this time, the controller 110 may control the plurality of UWB transceivers 201, 202, and 203 installed inside the vehicle 1 to perform the ROA function in the standby mode.
