A method is described for determining a position of a user device in relation to a vehicle, the vehicle including first and second receivers. The method includes transmitting a positioning signal by the transmitter of the user device, receiving the positioning signal by the first receiver and by the second receiver arranged at a distance from the first receiver, in at least one of the first and second receivers, receiving and identifying a reflected positioning signal reflected at a ground surface before reaching the first and second receivers, performing time synchronization between the transmitter and the first and second receiver, determining a position of the user device in a three-dimensional coordinate system based on a time-of-flight of the positioning signal received in the first and second receivers and on a time-of-flight of at least one reflected positioning signal received by at least one of the first and second receivers.

The invention relates to a mounted module (20) for a motor vehicle (1), comprising an optical sensor system (3) that is suitable for a) monitoring a detection area (21) located outside the vehicle (1), b) triggering a signal for starting an authentication process between an ID generator (13) and the motor vehicle (1) if a user (10) is detected in the detection area (21), c) monitoring an actuation area (22) which is located outside the vehicle (1) and differs from the detection area (21), d) providing an operating signal for the vehicle (1) if a user is detected in the actuation area (22).

A valet key operable as a vehicle key when lending a vehicle to a third person includes a state determination unit configured to determine whether or not the valet key is operable as the vehicle key when the valet key transmits a radio wave. The valet key further includes a communication subject setting unit configured to set a communication subject to which the valet key transmits the radio wave based on the determination result of the state determination unit.

The present disclosure provides an inlet control system and apparatus for an electric vehicle. It is an object of the present disclosure to provide an inlet control system and apparatus for an electric vehicle that permit the connector of the charging cable to be released from the inlet of the electric vehicle connected thereto only when an authorized user having a release control apparatus is adjacent to the electric vehicle regardless of whether one end of the charging cable connected to a power source is removed or not and prohibit release of the connector of the charging cable from the inlet of the electric vehicle when the user having the release control apparatus moves away from the electric vehicle.

Provided are a method for unlocking an intelligent lock, a mobile terminal, an intelligent lock and a server. The method includes following steps. A mobile terminal receives an initial key and a communication key from a server. The mobile terminal encrypts the initial key and preset key data by using the communication key to generate an unlocking verification code. The mobile terminal attaches the preset key data to the unlocking verification code, to obtain an unlocking verification code attached with the preset key data. The mobile terminal sends the unlocking verification code attached with the preset key data to the intelligent lock. The intelligent lock performs an unlocking operation based on the unlocking verification code attached with the preset key data.

In a vehicular portable device, a display unit is controlled to display an icon representing an instruction to an in-vehicle device when detecting that an acceleration equal to or greater than an activation threshold occurs in the vehicular portable device, a pressing force at an icon selection position, which is a position where the icon is selected by a touch sensor, is detected, and a control signal instructing execution of a command corresponding to the icon being selected is transmitted based on detection of the pressing force in a state where the icon is selected.

There is provided a method and a system for authorizing a user device to send a request to a vehicle in order to prevent a physical layer relay attack. The system comprises a vehicle comprising an acoustic transducer and an RF transceiver and a user device comprising an acoustic transducer and an RF transceiver. The method relates to a signaling scheme using a combination of acoustic and RF signals for preventing a successful physical layer relay attack.

A system and method provides efficient and highly reliable customer and asset tracking. A Personal Digital Key (PDK) is associated with and carried by a user or fixed to an asset. The PDK wirelessly communicates with a receiver/decoder circuit (RDC) that can be coupled to a variety of electronic devices. The RDC authenticates the PDK based on received data and stores information to track customers and provide improved service. The RDC can be coupled to or integrated with a variety of electronic devices. The operation of the electronic device is determined based on an identification code of the detected PDK and an identification code of the RDC. The electronic device, the PDK or both can be configured with a personalized user interface and execute specific functions based on stored state information associated with the PDK and RDC identification codes.

An access control system is provided that enables a network operations center to manage and control access to a plurality of remote sites and to verify servicing of the remote sites. Individuals in possession of electronic programmable keys can be provided opening codes to activate their keys while in the field, and to enable the keys to access one or more electronic locks located at the remote sites. Usage information associated with the utilization of the electronic programmable keys at the remote sites is stored on the electronic programmable keys. A lock attendance code is generated by the keys to verify attendance at the remote locations. The lock attendance codes are then transmitted to the network operations center where they are decoded to verify servicing of the remote sites.

A distribution device includes a server device configured to distribute key information to a portable terminal. The key information is used for a key system that determines whether or not to lock and unlock a vehicle, to make the vehicle travel, and to use a content providing device that provides digital contents in a vehicle cabin of the vehicle by transmitting the key information from the portable terminal to the vehicle. The server device is configured to distribute the key information to which restricted function information is added, to the portable terminal. The restricted function information is information indicating that locking and unlocking of the vehicle and use of the content providing device are permitted but traveling of the vehicle is not permitted.
