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.

Disclosed herein is a vehicle theft prevention device. The device can include a data store including event configuration data. The device can include one or more sensors that can sense various types of measurements proximate to a vehicle. The device can include a computing device in communication with the sensors. The computing device can read measurements from the sensors and determine that a particular event has occurred. The computing device can analyze the measurements to determine the particular event occurred based on the event configuration data. When the particular event occurs, the computing device can perform one or more remedial actions.

An apparatus and a method for controlling a vehicle door are provided to automatically unlock a door locked in vehicle crash. The apparatus includes a main battery, a sub-battery, a door actuator to lock or unlock the vehicle door, and a door controller to unlock the vehicle door which is locked by supplying electric power to the door actuator through the sub-battery, when the door controller determines that supply of electric power from the main battery is failed in the vehicle crash.

A mobile device wirelessly communicates with a vehicle device. The mobile device includes a receiving unit, a response signal generation unit, a transmission unit, a charging unit, and a charge state determination unit. The receiving unit receives a response request signal transmitted from the vehicle device. The response signal generation unit generates a response signal in response to the response request signal. The transmission unit transmits the response signal. The charging unit charges a built-in battery with an electric power supplied wirelessly or through wire from a power supply device. The charge state determination unit determines whether the charging unit charges the built-in battery. The mobile device is configured not to transmit the response signal, in a situation where the charge state determination unit determines that the charging unit is charging the built-in battery.

A vehicle-mounted device includes vehicle information detecting unit for detecting an on/off state of vehicle power, relay input/output unit for controlling an external relay configured to make a switch between a starting-disabled state and a starting-enabled state of a vehicle, and vehicle information-associated control unit for controlling the external relay based on a relay control command. The vehicle information-associated control unit controls the external relay based on an elapsed time since a change in the on/off state of vehicle power detected by the vehicle information detecting unit.

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.

The present invention relates generally to the field of vehicle key fobs. More specifically, the present invention relates to a vehicle key fob device comprised of a vehicle key fob that has a housing, a flashlight, a biometric scanner, a plurality of LED-illuminated buttons/emblems and a button that allows the color of the LED-illuminated buttons to change. The fob may have a plurality of buttons in differing embodiments, which are preferably illuminated via at least one LED that is positioned below each button. However, in one embodiment a singular large LED may sit below all buttons to illuminate the buttons simultaneously. The at least one LED can also produce any color known in the art, which can be changed by a user by pressing a color change button located on the side surface of the fob.

Disclosed is an eco-friendly vehicle capable of conveniently canceling a protection mode when the protection mode is entered due to a voltage drop of a low-voltage battery, and a power management method therefor. A power management method for an electrified vehicle may comprise controlling, by a power management controller, an out-vehicle switch from a first mode for changing a locked state to a second mode for battery reset when there is a request for entry into a protection mode for a low-voltage battery from a BMS, and entering the protection mode when the out-vehicle switch is changed to the second mode.

A security system is provided for a vehicle having an on-board diagnostic (“OBD”) data link cable and an OBD port. The system includes, a glass break sensor, and an input connector having a power input configured to be coupled to a vehicle battery voltage input of the OBD data link cable and to provide power to the glass break sensor. The glass break sensor is configured to detect a vibration, air pressure, or audio frequency disturbance and to generate an alarm signal when a disturbance is detected. The microprocessor is configured: to use OBD data to monitor whether the vehicle engine is running; to automatically arm the glass break sensor device when the vehicle engine is turned off; to automatically disarm the glass break sensor device when the vehicle engine is on; and to activate an alarm or a camera when in response to the alarm signal.
