An electronic key management system assisting device including: a connector (31) that is mounted in a vehicle and is used for a connection with an in-vehicle authentication device communicating with a management server using an in-vehicle communication device; and a requester (35B) that requests the management server to transmit an execution key for obtaining a permission for a transition to a registration mode in which an electronic key of the vehicle is registered in the in-vehicle registration device or an invalidation mode in which the electronic key registered in the in-vehicle registration device is invalidated using a communication device other than the in-vehicle communication device in a case which the in-vehicle authentication device connected through the connector is not able to communicate with the management server using the in-vehicle communication device.

A method for authorizing the use of a motor vehicle by a portable identification transmitter is provided. According to the method, a first vehicle antenna emits a first signal, which is received by an identification-transmitter antenna. The identification transmitter determines at least one of the spatial components of the first electromagnetic field of the received first signal. A second vehicle antenna emits a second signal, which is received by the identification-transmitter antenna. The identification transmitter determines at least one of the spatial components of the second electromagnetic field of the received second signal. A computer determines the angle between the determined spatial component of the first electromagnetic field and the determined spatial component of the second electromagnetic field. The identification transmitter transmits an authorization signal for authorizing use of the motor vehicle to the motor vehicle only if the angle exceeds a predetermined threshold value.

In general, techniques are described by which provide secured temporary access. A control system comprising a memory and a processor may be configured to perform various aspects of the secure temporary access techniques. The memory may comprise instructions that, when executed by the at least one processor, cause the at least one processor to determine, from a device operated by the authorized operator remotely from the vehicle, that a third party is authorized to temporarily access at least a portion of the vehicle, configure, responsive to determining that the third party is authorized to temporarily access at least the portion of the vehicle, the vehicle to secure the temporary access by the third party to at least the portion of the vehicle, and provide, responsive to securing the temporary access, and to the third party, the temporary access to at least the portion of the vehicle.

An electronic device that selectively performs a preventive action is described. During operation, the electronic device may acquire, using one or more sensors, a measurement in an environment that is external to the electronic device, where the measurement provides information associated with an object, and the measurement is a non-contact measurement. Then, the electronic device may detect the object based at least in part on the measurement. Moreover, the electronic device may estimate an intent of the object based at least in part on the measurement. Next, when the estimated intent is associated with a type of adverse event, the electronic device may perform the preventive action prior to an occurrence of the type of adverse event, where the preventive action reduces a probability of the occurrence of the type of adverse event or an amount of financial damage associated with the occurrence of the type of adverse event.

A system includes a mobile device and a fob, each having a short-range wireless transceiver. The mobile device is programmed to transmit a message to the fob indicating a fob action using the mobile device transceiver. The fob is programmed to, using the fob transceiver, receive the message and transmit a second message to a vehicle requesting the vehicle to perform the fob action.

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 approach is provided that logs radio frequency (RF) activity detected by a vehicle-based intrusion detection system. The logged activity is ingested at a machine learning system. The approach receives, by a conversational agent with access to the machine learning system, natural language (NL) user queries pertaining to the detected RF activity and presents, by the conversational agent, natural language system responses answering the NL user queries.

A passive entry system for a vehicle includes a portable fob and a communication and control unit disposed on the vehicle, the communication and control unit configured to control a function of the vehicle. The portable fob and the communication and control unit are configured to communicate ultra-wideband (UWB) signals therebetween. When the function of the vehicle is triggered, the communication and control unit initiates a double-sided UWB ranging session with the portable fob where (i) the portable fob determines a first distance between the portable fob and the communication and control unit, and (ii) the communication and control unit determines a second distance between the portable fob and the communication and control unit. The communication and control unit is configured to prevent control of the function of the vehicle if a final distance, determined from the first and second distances, is greater than the predetermined distance.
