The techniques of this disclosure relate to a system for transmitting radio frequency signals. The system includes a controller in communication with a first device fixed within a first housing attached to an exterior of a vehicle. The system also includes a second device fixed within a second housing attached to the exterior of the vehicle. The controller determines whether the first housing and the second housing are in a first position or in a second position. When the first housing and the second housing are in the first position, the controller transmits first radio frequency signals via the first device and via the second device. When the first housing and the second housing are in the second position, the controller transmits second radio frequency signals via the first device and via the second device. The system improves an antenna coverage area of the first device and second device.

A reader includes a transceiver and a control module. The transceiver is configured to, during a current connection event, monitor notification messages transmitted from a portable access device to a phone-as-a-key (PaaK) system of a vehicle, where the notification messages are transmitted to establish a communication link between the portable access device and the PaaK system. The control module is configured to: perform an in-phase and quadrature phase capture of the notification messages based on fields in one or more of the notification messages, where the fields include a mobile de-whitened section including two or more series of consecutive bits, where the consecutive bits in each of the one or more series are all zeros or all ones; based on the in-phase and quadrature phase capture, determine an angle-of-arrival of the notification messages, and indicate the angle-of-arrival to the PaaK system for permitted access determined by the PaaK system.

A vehicle control apparatus includes a processor including hardware, the processor being configured to determine whether or not a position of a key device is located within a predetermined area, and in a case where the position of the key device is located within the predetermined area, stop a smart key function of a vehicle or transmit a first signal requesting setting of a remote immobilizer function of the vehicle.

System, methods, and other embodiments described herein relate to securing wireless communications for passive keyless entry (PKE) to an asset. In one embodiment, a method includes, responsive to acquiring sensor data about at least a surrounding environment of a vehicle that provides access according to wireless communications with a remote device, analyzing the sensor data to define operating conditions identifying security characteristics of the vehicle and interactions of the remote device with the vehicle. The method includes activating a countermeasure from an available group of countermeasures according to at least the operating conditions. The method includes wirelessly communicating, by the vehicle with the remote device, according to the countermeasure.

Systems and methods for localization and passive entry/passive start (PEPS) systems for vehicles are provided. A communication gateway in a vehicle configured to establish a Bluetooth low energy (BLE) communication connection with a portable device. Sensors are configured to measure signal information about a communication signal sent from the portable device. A localization module is configured to receive the signal information from the sensors and determine a location of the portable device based on the signal information. A passive entry/passive start (PEPS) system is configured to receive the location of the portable device from the localization module and perform a vehicle function including at least one of unlocking a door of the vehicle, unlocking a trunk of the vehicle, and allowing the vehicle to be started based on the location of the portable device. Each of the plurality of sensors are synchronized.

A vehicle includes a memory and a processor coupled to the memory. The processor is configured to determine whether or not a communication interface is malfunctioning, the communication interface being configured to perform communication for confirming that a device, which holds a digital key for activation, is inside a vehicle cabin, and in a case in which it is determined that the communication interface is malfunctioning, perform processing that enables activation based on a result of authentication of the device.

A portable device, including: an unlocking portion configured to enable an operation for unlocking a door of a vehicle; and a processor, wherein, when the unlocking portion is operated in a case in which a reception sensitivity of a predetermined signal that is transmitted by wireless communication from the vehicle is a first sensitivity, the processor is configured to change the reception sensitivity to a second sensitivity that is a higher reception sensitivity than the first sensitivity.

An information processing device comprising a processor, the processor being configured to: in a case in which a door of a vehicle is locked, determine whether or not a terminal that operates as an electronic key is located in the vehicle; and in a case in which the terminal is determined to be located in the vehicle, perform control to restrict at least a subset of functions, among functions of the vehicle that are controlled in accordance with communications with the terminal, based on a lock trigger causing the locking of the door of the vehicle.

An electronic key system includes a door unit, an installed device, a portable device, at least one processor, and a storage medium storing. The storage medium stores a program that causes the processor to execute a composite authentication process and a simple authentication process. The composite authentication process permits unlocking of the door unit if all of the following conditions are satisfied: key information output from the portable device matches pre-registered key information; a user's motion matches pre-registered first motion information; and the motion matches pre-registered second motion information. The simple authentication process is executed during the time from locking of the door unit to elapse of a preset time or from locking of the door unit to when the portable device is located outside an authentication notification area. The simple authentication process permits unlocking of the door unit if the key information matches the pre-registered key information.

System, methods, and other embodiments described herein relate to adapting vehicle access by detecting a person carrying an object. In one embodiment, a method includes detecting a person near a vehicle for gaining access. The method also includes scanning the person for an object using a radar of the vehicle, wherein information from the radar indicates densities of the person and the object. Upon detecting the object using the densities, the method also includes adapting the access to a compartment of the vehicle.
