A method of transmitting signals from a first node having multiple transceivers to a second node is disclosed. The method comprises receiving a message from the second node at the first node, wherein the message is received by each of a plurality of transceivers of the first node; and transmitting by each of the plurality of transceivers a respective data frame to the second node in response to the message; wherein each transceiver initiates the transmission of its respective data frame a predetermined time period after receipt of the message by the transceiver; and wherein the transmissions of the data frames from the plurality of transceivers overlap. The data frames may form part of a two-way ranging exchange.

A vehicle system may include a vehicle configured to store a public key of the vehicle and a private key of the vehicle; a portable terminal configured to store the public key of the vehicle, a public key of the portable terminal, and a private key of the portable terminal; and a server configured to generate a token and encrypt the token with the public key of the vehicle and the public key of the portable terminal.

Systems and methods for performing a vehicle operation. One system includes a plurality of transceivers associated with a vehicle and a vehicle access system. The vehicle access system is configured to receive, via each of the plurality of transceivers, signal strength data associated with a portable communication device using a Bluetooth signal received at an antenna associated with each of the plurality of transceivers, and compare, for each of the plurality of transceivers, the signal strength data with a threshold signal strength value to perform a localization of the portable communication device generating the Bluetooth signal to determine whether the portable communication device is located inside or outside the vehicle. The vehicle access system is also configured to perform the operation based on whether the portable communication device is located inside or outside the vehicle.

In some implementations, a vehicle experience system may receive a service request associated with a vehicle. The vehicle experience system may qualify a driver for a vehicle experience involving the vehicle. The vehicle experience system may provide, to a user device associated with the driver, a verification code for authenticating the vehicle experience involving the driver and the vehicle. The vehicle experience system may provide, to a location management system associated with the vehicle, a notification that the vehicle is to be involved in the vehicle experience. The vehicle experience system may provide, to the location management system and based on receiving scan data being associated with the verification code, the authentication of the vehicle experience to enable a provisioning device to facilitate access to the vehicle.

Systems and methods are provided and include a processor configured to execute instructions stored in a computer-readable medium. The instructions include determining whether movement data associated with a user device and location data associated with the user device indicates that the user device is approaching a first location, determining whether the location data matches the movement data and a measured signal strength associated with at least one sensor of a vehicle, wherein the measured signal strength indicates a signal strength of a communication link between the user device and a control module of a vehicle, and determining that the user device is approaching the first location in response to a determination that the location data matches the movement data and the measured signal strength.

A delivery assistance device assists in an operation of a delivery service in which a vehicle cabin including a trunk of a vehicle used by a requester is able to be designated as a luggage delivery destination. The delivery assistance device includes a key information distribution unit configured to distribute key information that a deliverer of a company that provides the delivery service is to use to unlock a door for access to the vehicle cabin of the vehicle, to the company, and an entry authority information distribution unit configured to distribute entry authority information regarding an authority for the deliverer to enter a predetermined area in which the vehicle is present, to the company when the key information is distributed to the company by the key information distribution unit.

An electronic unlocking system includes an electronic lock and an electronic key. The electronic key includes processing circuitry and transmission circuitry. The processing circuitry is configured to obtain at least one piece of feature data when an unlock operation is triggered. The at least one piece of feature data includes data representing a user that triggers the unlock operation. The processing circuitry is configured to encrypt the obtained at least one piece of feature data to obtain encrypted data. The transmission circuitry is configured to send the encrypted data to the electronic lock to cause the electronic lock to execute the unlock operation.

Two different wireless protocols can be used for ranging between a mobile device and an access control system (e.g., a vehicle). The first wireless protocol (e.g., Bluetooth) can be used to perform authentication of the vehicle and exchange ranging capabilities between a mobile device (e.g., a phone or watch) and the vehicle. The second wireless protocol (e.g., ultra-wideband, UWB) can use a pulse width that is less than a pulse width used by the first wireless protocol (e.g., 1 ns v. 1 s). The narrower pulse width can provide greater accuracy for distance (ranging) measurements.

An information system that manages use of a cargo compartment of a vehicle by a plurality of users, the information system including a server configured to: acquire, from a provider of the vehicle, target range information regarding designation of a range of users who use the cargo compartment of the vehicle; receive user registration information including attributes of a user who desires use of the cargo compartment of the vehicle; and determine, based on the target range information and the user registration information, whether the use of the cargo compartment of the vehicle by the user is permitted or not.

An embodiment of the invention provides a system and method for wirelessly linking electronic marine components using Sub-1 GHz frequencies for long range, robustness in wet environment and highly resistant to wireless noise.
