Presented are vehicle control systems and logic for monitoring device batteries to provision virtual key functionality, methods for making/using such systems, and vehicles equipped with such systems. A method of operating a vehicle includes wire or wirelessly connecting a remote keyless entry (RKE) system with a wireless-enabled portable electronic device (PED) of a user. A vehicle controller receives a unique virtual key code from the user's PED to enable use of the RKE system and, after receiving the virtual key code, determines a battery charge level of the PED's battery. The vehicle controller then determines if the battery charge level is less than a preset minimum charge level and if the vehicle powertrain is off. If the powertrain is off and the battery charge level is less than the minimum charge level, the controller responsively commands a resident vehicle subsystem to execute a control operation for charging the PED battery.

Embodiments of the present invention provide a kit comprising a device and a charger each having a curved design. The device comprises a housing, a receive coil and a rechargeable electrical power storage element. The charger for the device comprises a yoke and a transmit coil. The receive coil axis and the transmit coil axis are arranged such that the receive coil and the transmit coil form an inductive coupling. Advantageously, the device may therefore be charged by the charger without a direct wired connection between the device and a power supply, despite the device and charger having a curved design.

Systems, devices, and methods are disclosed for unlocking a vehicle. An example vehicle includes a power system, a remote unlock system controlled by a remote unlocking device, and a door applique. The door applique comprises a wireless charger coupled to the power system, configured to charge the remote unlocking device, and a ridge configured to engage the remote unlocking device, wherein the wireless charger is configured to charge the remote unlocking device for a limited time.

The disclosure discloses a door lock including a locking mechanism, a power interface, a main control board, an environmental information collection device and a power supply management device, where the locking mechanism, power interface and power supply management device are respectively connected with the main control board, the environmental information collection device connected with the power supply management device, the environmental information collection device configured to collect and transmit environmental information on the surrounding of the door lock to the power supply management device; the power supply management device configured to carry out processing according to the environmental information and output a power supply mode matched with the environmental information to the main control board; and the power interface configured to execute an operation related to the power supply mode matched with the environmental information according to a power supply instruction from the main control board.

A system and method for energy saving on access control products is disclosed. An access controller controls access control readers, which in turn enable access to a building and/or interior areas of the building. The access controller can identify the locations of the access control readers relative to the building, such as whether the access control readers are located on the perimeter of the building for controlling access to the building, or whether the access control readers are located within the building for controlling access to interior areas of the building. The access controller can then place one or more of the access control readers into a power saving state without compromising overall building security, such as placing interior access control readers into a power saving state when the building is assessed to be unoccupied.

The disclosure discloses a door lock including a locking mechanism, a power interface, a main control board, an environmental information collection device and a power supply management device, where the locking mechanism, power interface and power supply management device are respectively connected with the main control board, the environmental information collection device connected with the power supply management device, the environmental information collection device configured to collect and transmit environmental information on the surrounding of the door lock to the power supply management device; the power supply management device configured to carry out processing according to the environmental information and output a power supply mode matched with the environmental information to the main control board; and the power interface configured to execute an operation related to the power supply mode matched with the environmental information according to a power supply instruction from the main control board.

A smart key searching apparatus includes a start button for selecting engine start or stop, a wireless charger performing wireless charging in a resonant magnetic coupling manner and transmitting an authentication request signal to a smart key, a radio frequency (RF) receiver receiving a response signal regarding the authentication request signal transmitted from the smart key, and a smart key controller requesting, when the start button is operated, the wireless charger to search for a smart key, and controlling power and engine ignition of a vehicle according to a response signal received through the RF receiver.

The disclosure discloses a door lock including a locking mechanism, a power interface, a main control board, an environmental information collection device and a power supply management device, where the locking mechanism, power interface and power supply management device are respectively connected with the main control board, the environmental information collection device connected with the power supply management device, the environmental information collection device configured to collect and transmit environmental information on the surrounding of the door lock to the power supply management device; the power supply management device configured to carry out processing according to the environmental information and output a power supply mode matched with the environmental information to the main control board; and the power interface configured to execute an operation related to the power supply mode matched with the environmental information according to a power supply instruction from the main control board.

An access control system having one or more system antennas that are configured to emit a first signal having a first frequency that is detected by the credential device. The credential device is configured to harvest electrical power from at least a portion of the detected first signal. At least a portion of the harvested electrical power may be used by the credential device to transmit a second signal to a reader device, the second signal containing information indicative of a credential stored on the credential device. Further, the second signal has a second frequency that is different than the first frequency of the first signal. The reader device and/or a server may evaluate the transmitted credential to determine whether the credential is associated with an authority to operate the reader device, such as, for example, an authority to unlock a lock mechanism of the reader device.
