An antenna driving apparatus includes: a direct current power source supplying direct current power to a human detecting IC detecting contact to a human detecting area by a user, the power source outputting a power source voltage to a first connecting line connected to a power source terminal of the IC and outputting a reference potential to a second connecting line connected to a GND terminal of the IC; an antenna driving circuit driving an antenna transmitting a signal to a portable device, the antenna driving circuit outputting a first antenna drive signal to the first connecting line and outputting an antenna drive signal; and a control unit performing switching control of the power source voltage and the antenna drive signal to be output to the first and second connecting lines and switching control of the antenna driving circuit.

A method for controlling wireless charging depending on a position of an FOB key in a wireless charging system provided in a vehicle and including an output unit, a wireless charging mount, and a controller, includes: transmitting, by the controller, a first signal informing a peripheral region of the wireless charging mount in which a wireless charging target is mounted that wireless charging is being performed in the peripheral region of the wireless charging mount in the case in which the wireless charging starts; transmitting, by the FOB key receiving the first signal, a second signal corresponding to the first signal to the controller; stopping, by the controller receiving the second signal, the wireless charging; and informing, by the controller, a user of the vehicle that the FOB key is present in the peripheral region of the wireless charging mount through the output unit.

A method for processing a vehicle key includes: obtaining gear information of the vehicle; and sending a first instruction to the vehicle key according to the gear information. The first instruction is configured to control the vehicle key to be adjusted from a current first mode to a second mode, and a power consumption of the vehicle key in the second mode is lower than a power consumption of the vehicle key in the first mode.

A vehicle that is configured to: acquire information relating to a remaining charge of a battery of a terminal configured to act as a digital key employed in control of a vehicle; and perform a predetermined notification in response to both of a determination being made that the remaining charge of the battery of the terminal is a predetermined threshold or lower based on the acquired information, and the vehicle being in a preset vehicle state.

A vehicle anti-theft device for a vehicle has a controller coupled to an ignition system of the vehicle, the controller having a communication module to wirelessly receive a signal to disable ignition of the vehicle when an individual wirelessly transmits the signal to disable ignition via a computing device. A hardware adapter is wirelessly coupled to the controller, the hardware adapter monitoring for unauthorized movement of the vehicle and allowing only authorized individuals who enter an authorization code to the hardware adapter to drive the vehicle, the hardware adapter wirelessly sending signals to disable ignition to the controller when unauthorized movement of the vehicle is detected or when an improper authorization code is received.

A portable device for hands-free access to a motor vehicle. The device includes a radiofrequency transceiver and a radiofrequency antenna. The radiofrequency antenna is modified by connecting between the two ends of the radiofrequency antenna: a) a resonant circuit at a near-field communication frequency in series with b) a radiofrequency open circuit, c) a near-field communication antenna, electromagnetically coupled to the modified radiofrequency antenna, d) a device for managing the near-field communication, connected to the near-field communication antenna, e) a rechargeable battery, and f) a device for recharging the battery in near-field communication, which is connected to the near-field communication antenna.

A rechargeable key fob device is disclosed, which is a modified key fob for vehicles comprised of multiple charging ports integrated directly into the body of the fob. The rechargeable key fob device comprises a fob component with at least one charging port integrated into it. Specifically, there are two versions of the device, with one version including its own charging port and specialized cord for charging. The second version includes multiple common existing ports, such as USB A, USB C, and lightning ports. Users can simply plug the fob into a desired charging cord, then into an electrical outlet. The internal battery is charged to prevent a user from having to take apart the key fob and replace its battery.

The present disclosure provides an apparatus, method and system for use with a vehicle having passive keyless entry and start (PKES) system including a vehicle unit and a key fob storage unit. The vehicle unit is to be installed with the vehicle having a first transceiver, a first relay transceiver an authentication unit, a first controller for controlling said first relay transceiver allowing said transmission if said user is authenticated. The key fob storage unit comprises at least one housing for securely holding at least one key fob associated with said PKES systems of said vehicles, a second, said second wireless relay w wherein said first relay transceiver and said second relay transceiver allows said PKES system and said key fob to communicate from a distance larger than a range of said PKES system signals.

A portable device is provided that functions as a wireless key for a door and operates on a secondary battery. The portable device includes a wireless communicator for performing wireless communication with a system that controls a lock state of the door, and a controller that controls the wireless communicator. The controller is configured to perform, by using the wireless communicator, transmitting an advertise signal being a wireless signal for establishing communication connection with the system, acquiring data indicating a remaining power of the secondary battery, and changing an operating mode of the portable device based on the remaining power. The operating mode relates to transmission of the advertise signal.
