A system for passive locking and unlocking a vehicle is described that includes a memory for storing executable instructions and a processor configured to execute the instructions to unlock the vehicle using a time of flight to transmit the trigger request between the vehicle and the first key fob. The processor receives, from a first key fob, a trigger request to unlock the vehicle, and determines, based key fob identifiers that identify the first key fob and a second key fob that is also near the vehicle, that the first and second key fobs are associated with a vehicle. The processor selects the first key fob based on a key fob characteristic. The processor evaluates the time of flight using the first key fob, and unlocks the vehicle based on the time of flight satisfying a threshold for signal transmission flight time.

In some exemplary processes for accessing a vehicle, a transit request is initiated. The transit request summons a vehicle towards a location of a user device. Information generated in response to the transit request is received. The information includes first authentication information and second authentication information. Third authentication information from the vehicle is received using a first wireless communication protocol. A determination is made as to whether the third authentication information corresponds to the first authentication information. In accordance with determining that the third authentication information corresponds to the first authentication information, a wireless communication connection is established with the vehicle using a second wireless communication protocol and the second authentication information. The second wireless communication protocol is different from the first wireless communication protocol. Using the second wireless communication protocol, instructions to unlock a cabin of the vehicle are sent.

Disclosed embodiments include systems, vehicles, and methods for selectively activating or deactivating systems associated with an object based on a position of a transmission source relative to the object. In an illustrative embodiment, a system includes signal sensing devices positionable around an object that are configured to detect a transmission signal from a transmission source. A control system is operably coupled with the signal sensing devices. The control system is configured to determine a position of the transmission source relative to the object, the position including an orientation relative to the object and/or a location within a perimeter of the object, based on a relative received signal strength of the transmission signal received by at least one of the signal sensing devices and to initiate operation of at least one subsystem associated with the object based on the position of the transmission source relative to the object.

In a method for determining a motion state of a portable transceiver device for unlocking a door, especially a vehicle door, a radio signal is received at the portable transceiver device. Moreover, a signal strength of the received radio signal is determined. Furthermore, a signal strength variation is determined by comparing the determined signal strength to a previously determined signal strength or by comparing the determined signal strength to a predefined signal strength. Subsequently, it is established that the portable transceiver device is in motion if the amount of signal strength variation exceeds a preset threshold. Alternatively, it is established that the portable transceiver device is at rest if the amount of signal strength variation is equal or lower than the preset threshold. Moreover, a method for remotely unlocking a door, especially a vehicle door, is presented. Also, a portable transceiver device for unlocking a door, especially a vehicle door, is described.

A system and method are provided for determining location information of a vehicle keyfob relative to an object. The system and method may include communicating with a primary device (e.g., a smartphone) having primary device authentication information with respect to the object, and receiving parameter information, such as keyfob authentication information, from the primary device.

A vehicle door opening and closing control system may include an antenna provided at a vehicle, the antenna being configured to wirelessly communicate with a user's mobile device to recognize the location of the user's mobile device, a door opening and closing device configured to open or close a door of the vehicle, a rain sensor configured to detect a rainy weather state outside the vehicle, and a controller configured to control the operation of the door opening and closing device based on the location of the mobile device recognized by the antenna or the rainy weather state outside the vehicle detected by the rain sensor.

A method and a system detect damage caused to a parked vehicle and identify the originator of the damage.

A control device that communicates with a first communication device and a second communication device, the control device comprising: a determination section configured to determine a position of a terminal on a basis of a first ranging result obtained from a radio wave communicated between the first communication device and the terminal and a second ranging result obtained from a radio wave communicated between the second communication device and the terminal, wherein the first communication device is disposed at a first position where it is difficult to directly receive the radio wave between a first area and a second area that are separated by a first member including material through which it is difficult for the radio wave to penetrate, and the second communication device is disposed at a second position where it is difficult to directly receive the radio wave between the first area and the second area.

A vehicle control system includes: a possible user determination section that allows a first camera having a first resolution to capture an image around a vehicle to determine whether or not the captured image includes a possible facial image of a user; a user determination section that allows a second camera having a second resolution which is higher than the first resolution and consuming more power than the first camera to capture an image around the vehicle to determine whether or not the captured image includes a facial image of the user in a case where the possible user determination section determines that the possible facial image of the user is included; and an entry permission section that permits the user to enter the vehicle in a case where the user determination section recognizes that the facial image of the user is included.

A transportation vehicle having a BLUETOOTH® Low Energy (BLE) system to send and receive BLE advertising signals, BLE connection request signals and BLE data signals via at least one antenna, a central locking system to lock or unlock at least one vehicle door of the transportation vehicle, and a control unit to activate the BLE system and to activate the central locking system based on the BLE data signals. Also disclosed is an electronic vehicle radio key and a system for passive access to a transportation vehicle including a transportation vehicle, an electronic vehicle radio key and a smartphone. The system allows a user passive access to the transportation vehicle, both with the aid of the electronic vehicle radio key and with the aid of the smartphone.
