A system and method for using a portable device to communicate with a vehicle to authorize one or more vehicle operations. The portable device may authorize the vehicle to unlock/lock doors, start the vehicle engine, or mobilize the vehicle, or a combination thereof. The vehicle may include a vehicle transmitter system with one or more transmitters disposed at various locations on the vehicle, and the portable device may be configured to monitor a communication strength between the portable device and the one or more transmitters of the transmitter system. Based on the monitored signal strength, the portable device may determine location information about itself.

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.

Systems and methods are provided for operating a remotely operable lock. In an example embodiment, a method comprises receiving credentials at a web service from a portable electronic device, authenticating the credentials, and based on a successful authentication, issuing a command for receipt by the lock from the web service or the portable electronic device.

A control apparatus for a vehicle disclosed herein is applied to a vehicle configured to perform pre-air conditioning of the interior of the vehicle by starting an internal combustion engine according to a remote control signal sent from a remote controller. When starting pre-air conditioning according to the remote control signal, the control apparatus sets the control mode of the vehicle to a drive-disabling mode, which is a control mode that disables an operation for driving the vehicle. If a specific mode-cancelling operation is detected in a situation in which the remote controller is present in the interior of the vehicle while the control mode of the vehicle is being set to the drive-disabling mode, the control apparatus cancels the drive-disabling mode while leaving the internal combustion engine operating.

A method for operating a motor vehicle door, according to which method the motor vehicle door is equipped, for example, with an actuator and/or a motor vehicle door lock in the form of a current consumer, and at least one sensor for detecting door movements. In addition, a control unit that evaluates signals from the sensor is provided which can be transferred from a rest mode into an operating mode and back again according to the recorded door movements. According to the invention, the door movement causes the sensor that is deenergised in the rest mode to generate a current pulse.

The present disclosure relates to a wake-up control apparatus and method for a vehicle. In response to a signal from a remote controller, power is supplied to some apparatuses selected from a plurality of apparatuses as an activation target, and the activation target performs an initialization operation through the supplied power, so that enough preliminary initialization time may be secured to completely perform the initialization operation on the activation target before an ignition of the vehicle is turned on, some of the plurality of apparatuses may be selectively and partially driven to reduce battery power consumption, and when the ignition of the vehicle is turned on, the vehicle may be driven immediately without waiting, which makes it possible to improve user convenience.

Systems and methods are provided for operating a remotely operable lock. In an example embodiment, a method comprises receiving credentials at a web service from a portable electronic device, authenticating the credentials, and based on a successful authentication, issuing a command for receipt by the lock from the web service or the portable electronic device.

A method for operating an access control comprises creating a plurality of wake-up schedules for each of one or more wireless transceivers. Each of the plurality of wake-up schedules may be configured to control how frequently a particular wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the particular wireless transceiver may be different from another one or the plurality of wake-up schedules for the particular wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the particular wireless transceiver such that a duration of time between wake-ups for the particular wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for each of the one or more of the wireless transceivers may be configurable by an administrative user via an interface.
