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.

Abstract
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.

9. A method for detecting an intruder inside a vehicle, comprising:
-
monitoring a load in the vehicle after the vehicle is vacated and locked, the monitoring comprising receiving an first load signal representing an initial load in the vehicle after the vehicle is vacated and locked, periodically receiving subsequent load signals representative of subsequent loads in the vehicle, and replacing the value of the first load signal with the value of the subsequent signal if a difference between the first load signal and the subsequent load signal does not exceed the predetermined threshold; and signaling, via an intruder alarm, that the intruder is in the vehicle when the difference between the first load signal and the subsequent signal exceeds the predetermined threshold. - View Dependent Claims (10)

11. A system for detecting an intruder inside a vehicle, the system comprising:
-
a load sensor coupled to the vehicle; an alarm module that activates an intruder alarm; and an intruder detection control module coupled to the load sensor and to the alarm module, the intruder detection control module comprising a processor receiving an first load signal representative of an initial load in the vehicle from the load sensor 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 the subsequent signal if a difference between the first load signal and the subsequent load signal does not exceed the predetermined threshold, and activating the intruder alarm indicating that an intruder is in the vehicle when the processor determines that the difference between the first load signal and at least one of the subsequent signals exceeds a predetermined threshold. - View Dependent Claims (12)
