Apparatus and method for detecting an intruder inside a vehicle

摘要

A method and apparatus are provided for detecting an intruder inside a vehicle. The apparatus comprises a load sensor coupled to the vehicle, and a processor. The processor is coupled to the load sensor and is configured to monitor the load in the vehicle after the vehicle is vacated and locked and to determine if the load in the vehicle changes by more than a predetermined threshold.

主权项

1. A vehicle security device, comprising:
a load sensor coupled to a vehicle; and a processor coupled to the load sensor, the processor monitoring a load in the vehicle after the vehicle is vacated and locked by receiving first load signal representative of an initial load in the vehicle after the vehicle is vacated and locked, periodically receiving subsequent load signals from the load sensor representative of subsequent loads in the vehicle, replacing the value of the first load signal with the value of one of the subsequent load signals when a difference between the first load signal and the subsequent load signal does not exceed a predetermined threshold, and activating an intruder alarm indicating that an intruder is in the vehicle when the difference between the first load signal and the subsequent load signal exceeds the predetermined threshold.
