The components of the alarm system are fully enclosed within a portable housing and require no external power or data signal connections. A mobile transmitter generates a proximity signal indicating a given range from the vehicle. An audible alarm signal and a GPS location signal are generated in response to the output of one or more sensors indicating a particular occurrence, if a transmitter is outside of the given range, indicating that the driver has left the vehicle unattended and vulnerable to attack. When the vehicle is driven by an authorized driver having the transmitter, the received proximity signal indicates that the driver is within the given range, preventing the generation of the audible alarm resulting from sensors being triggered by shifting cargo in the cargo compartment resulting from vehicle movement and irregular road surface conditions during transit.

The disclosure is related to providing information on a battery charge state of a parked electric vehicle through at least one of one or more light lamps and one or more speakers of the parked electric vehicle. Particularly, the disclosure may control at least one of a lamp light color, a lamp blink pattern, and a sound pattern according to the battery charge state information such that a user can recognize the battery charge state away from the electric vehicle through hearing and/or vision.

Disclosed is a system for detecting an operating state of a vehicle engine. The system comprises: an input coupled to a power line of a vehicle; means to filter out relatively high frequency transient noise components of a signal received from the power line; a first detector for receiving the filtered signal and detecting when transient noise associated with the power line rises above a first threshold and generating a first detection signal in response thereto; a second detector for receiving the filtered signal and detecting when the transient noise falls below a second threshold, which is lower than the first threshold, and generating a second detection signal in response thereto; and means for generating a first output signal in response to the first detection signal and a second output signal in response to the second detection signal.

Disclosed is a system for detecting an operating state of a vehicle engine, for example, in order to arm or disarm a vehicle alarm system. The system comprises: an input coupled to a power line of a vehicle; means to filter out relatively high frequency transient noise components of a signal received from the power line; a first detector for receiving the filtered signal and detecting when transient noise associated with the power line rises above a first threshold and generating a first detection signal in response thereto; a second detector for receiving the filtered signal and detecting when the transient noise falls below a second threshold, which is lower than the first threshold, and generating a second detection signal in response thereto; and means for generating a first output signal in response to the first detection signal and a second output signal in response to the second detection signal.

The disclosed system obtains a current time and a time fence indicating a daily time period and determines whether the current time is within the time fence. Upon determining that the current time is outside the time fence, the system operates the battery in a low-power mode, where the low-power mode is configured to conserve power associated with the battery. When the battery is in the low-power mode and the system detects an unusual operation associated with the vehicle, the system generates a notification of the unusual operation and sends the notification of the unusual operation to a server.

When the battery is in the low-power mode and the system detects an unusual operation associated with the vehicle, the system sends an indication to multiple monitoring units coupled to multiple vehicles within a predetermined area to send a notification indicating the unusual operation.

Systems and methods are provided for monitoring and detecting unauthorized access to a vehicle. The systems and methods may receive surveillance data of the vehicle using a sensor. The systems and methods may detect, from the surveillance data, an intrusion to the vehicle by an entity. The systems and methods may transition the sensor out of a minimal power state upon detecting the intrusion to the vehicle. The systems and methods may perform a scan of the vehicle to obtain information indicating a type of the intrusion using the sensor. The systems and methods may determine, from the scan, the type of the intrusion to the vehicle is a threat intrusion by determining the entity causing the intrusion is unauthorized and the entity is performing an unauthorized action. The systems and methods may perform a safety action to interfere with the threat intrusion.
