An access arrangement for a vehicle comprises a vehicle-side unlocking device for unlocking a locking mechanism. Furthermore, it comprises a vehicle-side rechargeable electrical energy storage device which is set up to supply the unlocking device with energy independently of the on-board power supply of the vehicle. Moreover, the access arrangement has a vehicle-side energy supply device comprising a first section for receiving wirelessly transmitted energy and for converting the transmitted energy into electrical energy, and a second section for charging the vehicle-side rechargeable electrical energy storage device. In particular, the access arrangement also comprises a vehicle-side authentication device for checking access authorization, which is supplied with energy independently of the on-board power supply by means of the vehicle-side rechargeable electrical energy storage device. It is therefore no longer necessary to equip a mobile identification transmitter carried by a user with the access arrangement with a mechanical key.

To provide a mechanism that makes it possible to suppress increase in electric power consumption while assuring accuracy of measuring a distance between devices. there is provided a control device comprising: a control section configured to cause a ranging process of measuring a distance between communication devices to be executed a designated number of times, and control a subsequent process that is a process of using a ranging value that satisfies a designated allowable value, on a basis of whether or not at least any of a plurality of ranging values that have been acquired satisfies the designated allowable value, wherein the control section controls start of the subsequent process when the ranging value that satisfies the designated allowable value is acquired.

A vehicle control apparatus includes a processor including hardware, the processor being configured to: determine whether or not a state of a key device has reached a predetermined state requiring setting of a remote immobilizer function; and transmit, in a case where the state of the key device has reached the predetermined state, a first signal requesting setting of the remote immobilizer function.

An entry backup energy assembly is provided for an electric latch that is powered by a main power source during a normal operating condition. The entry backup energy assembly includes a backup battery electrically coupled to an activation switch that is moveable to one of an activated state and a deactivated state. The entry backup energy assembly also includes a backup controller coupled to the activation switch and the backup battery and the electric latch. The backup controller is configured to receive power from the backup battery in response to movement of the activation switch to the activated state and wirelessly communicates with a user authentication unit to authenticate a user. The backup controller provides the backup electrical energy to the electric latch and enables the user to operate the electric latch during a failure operating condition in response to the user being authenticated.

The present disclosure includes a plurality of sensors that acquire information including an external environment of a vehicle, and an arithmetic unit that controls an onboard device of the vehicle in response to the information input from the plurality of sensors. The arithmetic unit includes: a vehicle status identifier that identifies a status of the vehicle; a plurality of functional sections that are actuated in accordance with the status of the vehicle and generate a control signal to be transmitted to the onboard device; and a power source controller that controls supply and cutoff of power to the functional sections so that the power is supplied to a predetermined combination of the functional sections in accordance with the status of the vehicle.

A system is disclosed and includes a plurality of antennas. Each antenna includes a plurality of conductive elements and is circularly polarized. The plurality of conductive elements is configured to receive radio frequency (RF) signals. A first end of each of the plurality of conductive elements is electrically coupled to a printed circuit board, which includes a plurality of coupler circuits and a switching circuit. The plurality of coupler circuits is configured to combine the RF signals and output a signal to the switching circuit based on the combined RF signals. The switching circuit is configured to selectively output one of the signals based on at least one control port of the switching circuit being selectively activated by a control signal. The system also includes a microcontroller configured to determine, based on at least one of the signals, an angle of arrival associated with the plurality of antennas.

A vehicle control system (VCS) in a passenger compartment interfaces with underhood components using a Bluetooth® link. The underhood components include a siren assembly with a sound generator and backup battery. The battery enables the siren assembly to function after the vehicle's battery is disabled. The siren assembly includes a Bluetooth® transceiver for establishing the link with the VCS. The siren assembly monitors the hood of the vehicle through a hood sensor, to detect unauthorized opening. In response to such opening, the siren assembly transmits an alarm to the VCS, which transmits an alarm to a user's mobile device and/or a security service. The sound generator may also be activated, by itself or under control of the VCS. The siren assembly connects to the engine computer/ignition module, to allow the VCS to monitor engine speed, and facilitate proper start of the engine when the VCS receives a remote start command.

An affixable device can include a locking mechanism, a force-limiting mechanism, and a sensing mechanism. The locking mechanism can include an engagement component configured to disable the locking mechanism. The force-limiting mechanism can be configured to limit a locking force of the locking mechanism. The sensing mechanism can be coupled to the engagement component, and can be configured to determine that the force-limiting mechanism has limited the locking force of the locking mechanism. In response to determining the force-limiting mechanism limiting the locking force, the sensing mechanism can cause the engagement component to disable the locking mechanism.

A sensing device can include an accelerometer, a transceiver, and a computing device in communication with the accelerometer and transceiver. The computing device can transmit a first set of signals at a first power level to a remote device. The computing device can determine, via the accelerometer, a movement of the sensing device. The computing device can increase a power level for transmission from the first power level to a second power level in response to the movement. The computing device can transmit future signals at the second power level to the remote device.
