A vehicle includes a powered door having an actuator to move the door between open and closed positions, a transceiver configured to communicate with one or more mobile devices, and an imaging device oriented to capture images in a region proximate to the powered door. A controller processes the captured images and controls the actuator to move the door to the open position when a mobile device is detected proximate the vehicle and a user is detected in the captured images located in a door detection zone. The controller moves the door to the open position when a face of a user is recognized as an authorized user located in the door detection zone. The controller moves the door to the open position when a gait of the user is detected and identifies the gait are indicative of an authorized user located in the door detection zone.

A vehicle wireless communication system includes: a vehicle including an output circuit; and first and second communication devices configured to wirelessly communicate with the vehicle. In a case in which the first communication device is positioned in a first area including one point located inside the vehicle, the use of the vehicle is permitted. In a case in which the first communication device is positioned in a second area including the one point and the second communication device is not positioned in a third area including the one point, the output circuit outputs a notification that there is a possibility of failure to carry the second communication device. In a case in which the first communication device is positioned in the second area and the second communication device is positioned in the third area, the output circuit of the vehicle does not output the notification.

A locking and unlocking system includes a controller. The controller is configured to acquire a state of locking and unlocking of a vehicle that is locked and unlocked based on locking and unlocking instruction information acquired from a portable terminal, and send a notification to a first device associated with the vehicle, when the vehicle is not locked during a period of time from when the vehicle is unlocked based on the locking and unlocking instruction information acquired from the portable terminal until a first timing.

A method for a device for a vehicle is disclosed, wherein the device comprises a key chip. The method comprises obtaining information relating to the release of a key signal or of an immobilizer signal from a central computer via a wireless mobile communication system. The method further comprises providing a control signal to the key chip based on the information relating to the release of the key signal or of the immobilizer signal, wherein the control signal is designed to allow the key chip to generate the key signal or the immobilizer signal. The method further comprises providing the key signal and/or the immobilizer signal, by the key chip, via a wireless communication link to a central locking system and/or an immobilizer system of the vehicle after the control signal is obtained.

A method for vehicle function control includes: in response to determining that a distance between a vehicle and a terminal is within a bluetooth low energy (BLE) communication distance and the terminal has a digital vehicle key of the vehicle, establishing a BLE connection between the vehicle and the terminal and performing a BLE ranging; and when a BLE ranging result meets a preset condition, controlling the vehicle to unlock a door lock.

Systems and methods for phone-as-a-key range extension are disclosed. An example disclosed vehicle includes an integrated antenna array with a plurality of antenna located on a roof of the vehicle. The plurality of antenna includes a personal area network antenna. The example vehicle also includes a personal area network module communicatively connected to the personal area network antenna. Additionally, the vehicle includes a key phone unit communicatively connected to the personal area network module. The example key phone unit performs key fob functions as requested by an authorized mobile device.

A symmetric key-based generation and distribution system and method for a vehicle access authentication framework is provided, the framework comprising: a first device operated by a car owner, a second device operated by a delegated user, and a third device residing in a vehicle. The first device is configured to: request for an authentication key from the third device, the request for the authentication key comprising an ID of the first device, id.sub.O; receive an authentication key K.sub.id.sub.O from the third device; and generate a delegated authentication key K.sub.id.sub.U based on authentication key K.sub.id.sub.O and an ID of the second device in response to receiving a request for delegated authentication key from the second device, the request for delegated authentication key comprising the ID of the second device.

The invention relates to a method for transmission of a secure virtual key (VK) from a server (50, S) to a mobile terminal (20, T) capable of communicating with the server (50, S), comprising the steps of: a) reception by the server (50, S) of a certification request from the mobile terminal (20, T), b) provision and downloading on the mobile terminal (20, T), by the server (50, S), of a user application (25), and c) provision of the mobile terminal (20, T), by the server (50, S), with a virtual key (VK), and d) downloading and securing of the virtual key (VK) in a security element (27) of the mobile terminal (20, T), characterised in that said security element is formed by an encrypting software environment (27).

A power door system for a vehicle including a plurality of power-operated doors is provided. The system includes a passive remote entry device configured to emit a signal to one or more cooperating vehicle receivers and a controller configured to cause the power door system to open the at least one power-operated door when the passive remote entry device signal is received and an individual is detected in a predefined activation zone for a predetermined period of time. The system further includes a vehicle-mounted user detection device. The passive remote entry device may be selected from the group consisting of a key fob, a smart key, a key card, a cellular telephone or smartphone configured with a phone-as-a-key function, a Bluetooth®-activated and vehicle-recognized cellular telephone, a Bluetooth®-activated and vehicle-recognized smartphone, and a Bluetooth®-activated and vehicle-recognized smartwatch.
