A vehicle control method using a smartphone may include pairing a smartphone of a driver with a head unit of a vehicle, the head unit of the vehicle turning on an application in the smartphone through Bluetooth communication, authorizing the driver through the application in the smartphone, and the head unit unlocking a door of the vehicle through a smart key unit of the vehicle.

The present invention relates to a method that allows a CSCA to enable an iFOB key system once it is turned on by pressing a function button. When the function button is released, the iFOB key system is turned off. The iFOB key system includes the ERFTS, so when the iFOB key system is turned on/off, the ERFTS is also turned on/off. The embodiment of the CSCA has a double-action switch, a triple-action switch, a timer, a timer circuit and all of the circuitries that are associated with an iFOB key. The CSCA controls the length of time that current is allowed to flow from a battery source to an iFOB key system; it is this type of control that prevents an ERFTS and a customer's property from being compromised. The iFOB key system is always in the off position until it is turned on.

Provided are an electronic device and an operation method thereof. The electronic device may include: first and second antennas to receive a signal output by an external electronic device; a communication circuit configured to control the first antenna and the second antenna; and a processor. The processor may be configured to: receive the signal through the first antenna and the second antenna; measure a first distance between the first antenna and the external electronic device using the signal received by the first antenna; measure a second distance between the second antenna and the external electronic device using the signal received by the second antenna; determine a movement direction of the external electronic device based on a change in a difference between the first distance and the second distance; and perform a preset operation corresponding to the movement direction of the external electronic device. Other embodiments are also possible.

A system for a closure lock comprises a battery-powered remote module with a lock mechanism for operating the lock, the remote module communicating with a base station coupled to a closure controller, the base station able to send lock control signals to the remote module to operate the lock. The module is arranged to have an operation mode and a non-operation mode, power consumption in the non-operation mode being lower than that in the operation mode, and is further configured to switch between the modes based on instructions from the base station. In the non-operation mode, the module maintains a communication link with the base station based on a pre-established synchronisation protocol. The invention provides reliability against interference between base station and remote module, whilst greatly limiting the power consumption of the remote module.

The present invention relates to a method for preventing security breaches of a passive remote keyless entry system for authorizing access to a vehicle. The passive remote keyless entry system comprises a base station located at the vehicle and a mobile device, in particular a remote key, wherein the base station comprises a first processor unit and a first transceiver unit, the first transceiver unit comprises a timing device, the mobile device comprises a second processor unit and a second transceiver unit, an air travel time T of a single message sent back and forth from the base station to the mobile device is measured, and access to the vehicle is granted depending on the measured air travel time T.

Various embodiments may include systems for unlocking a motor vehicle. For example, an apparatus may include: a motor vehicle key for unlocking a motor vehicle having a remote engine start and/or vehicle entry system. The motor vehicle key comprises a Bluetooth antenna and a motor vehicle communication antenna. A controller of the motor vehicle key is configured to: use the Bluetooth antenna to set up a Bluetooth link to a mobile radio terminal using an activation key stored in a memory of the motor vehicle key; and instruct a motor vehicle controller installed in the motor vehicle to prompt an operation of the motor vehicle.

A mobile device possessed by a user is equipped with: a motion sensor which is capable of detecting the motion of the mobile device; a receiver which is capable of receiving a polling signal transmitted from equipment; and a control unit which is configured so as to set, in response to whether or not the polling signal has been received by the receiver, the sampling speed with which the motion sensor detects the motion of the mobile device.

A radio key for an access system of a motor vehicle includes a receiver circuit with at least three LF receiver coils for reception of a low frequency signal. The receiver coils are oriented in different spatial directions. A central control circuit includes a microcontroller coupled to the receiver circuit. The control circuit with the microcontroller can assume an energy-reduced resting state and an active operating state. The receiver circuit is configured to awaken the control circuit from the resting state when a signal is received by the LF receiver coils. The central control circuit is configured to activate each of the LF receiver coils separately and to query a received signal strength. The central control circuit then selects the LF receiver coil with the highest signal strength for a subsequent signal reception.

Methods, devices, and systems are provided for performing and/or limiting features based on a determined motion associated with a portable device. When the portable device is determined to be in motion, a feature control application running on the portable device prevents at least one radio frequency identification (RFID) component of the device from communicating with RFID reading devices. When the portable device is still, or not in motion, the feature control application running on the portable device prevents the at least one RFID component of the device from communicating with RFID reading devices. Among other things, this feature control of a portable device can prevent theft of data in an access control system, credit payment system, and/or other data transfer system.

A locking device includes a locking mechanism configured to lock and unlock different types of objects upon a corresponding command from a separate remote device such as a smartphone controlled by a user and running an application program. A motion sensor senses any physical motion of the locking device, and an alarm provides a visual and/or audible alarm upon sensed motion or tampering of the locking device. A location tracker (GPS) continuously senses a location of the locking device. A communication module is in two-way (cellular) signal communication with the remote device, which transmits signals to the communication module indicative of a user command to lock and unlock the locking mechanism. The communication module transmits signals to the remote device indicative of a status of various parameters of the locking device. A processor is configured for signal processing of the various signals within the locking device.
