Abstract

A vehicle security system may include a vehicle controller and a first wireless communications device carried by the vehicle, and a wireless security sensor(s). The wireless security sensor(s) may include a portable housing, a motion sensor carried by the portable housing to detect motion thereof, a second wireless communications device carried by the portable housing to communicate with the first wireless communications device, and a sensor controller carried by the portable housing. The sensor controller may cooperate with the motion sensor and the second wireless communications device to determine when motion of the portable housing exceeds a first security alert threshold and send a first security alert message to the vehicle controller based thereon, and determine when the first security alert threshold is exceeded for a predetermined time and enter a power saving mode. The vehicle controller may generate a first alarm responsive to the first security alert message.

Claims

1. A vehicle security system comprising:

a vehicle controller carried by the vehicle;

a first wireless communications device carried by the vehicle and coupled to said vehicle controller;

at least one wireless security sensor comprising

a portable housing,

a motion sensor carried by said portable housing to detect motion thereof,

a second wireless communications device carried by said portable housing to communicate with said first wireless communications device, and

a sensor controller carried by said portable housing and configured to cooperate with said motion sensor and said second wireless communications device to

determine when motion of said portable housing exceeds a first security alert threshold, and send a first security alert message to said vehicle controller based thereon, and

determine when the first security alert threshold is exceeded for a predetermined time and enter a power saving mode based thereon, and

a battery carried by said portable housing and powering said motion sensor, second wireless communications device and sensor controller;

said vehicle controller generating a first alarm responsive to the first security alert message.

2. The vehicle security system of claim 1 wherein said at least one wireless security sensor has a unique identifier (UID) associated therewith.

3. The vehicle security system of claim 2 wherein said sensor controller is switchable to a learning mode to send the UID to said vehicle controller.

4. The vehicle security system of claim 2 wherein said at least one wireless security sensor comprises a plurality thereof.

5. The vehicle security system of claim 4 wherein said sensor controller generates a low battery message including the UID of the associated wireless security sensor;

and wherein said vehicle controller generates a unique low battery alert for each respective wireless security sensor based upon its UID.

6. The vehicle security system of claim 1 wherein said sensor controller is further configured to determine when motion is above a second security alert threshold lower than said first security alert threshold and send a second security alert message to said first wireless communications device based thereon;

and wherein said vehicle controller is configured to generate a second alarm responsive to the second security alert message.

7. The vehicle security system of claim 1 wherein the predetermined time is greater than 2 seconds.

8. The vehicle security system of claim 1 wherein said motion sensor comprises a three dimensional (3D) accelerometer.

9. The vehicle security system of claim 1 wherein said motion sensor comprises a tilt sensor.

10. The vehicle security system of claim 1 wherein said at least one wireless security sensor further comprises an inductive charging circuit carried by said portable housing and cooperating with said sensor controller to inductively charge said battery.

11. The vehicle security system of claim 1 wherein said vehicle controller comprises at least one of a remote start controller, an alarm system controller, and a remote keyless entry controller.

12. The vehicle security system of claim 1 wherein the first alarm comprises at least one of a local audible alarm, and a local visual alarm.

13. The vehicle security system of claim 1 wherein the first alarm comprises a wireless alarm transmission.

14. A wireless security sensor for use with a vehicle security system comprising a vehicle controller carried by a vehicle and a first wireless communications device carried by the vehicle and coupled to the vehicle controller, the wireless security sensor comprising:

a portable housing;

a motion sensor carried by said portable housing to detect motion thereof;

a second wireless communications device carried by said portable housing to communicate with the first wireless communications device;

a sensor controller carried by said portable housing and configured to cooperate with said motion sensor and said second wireless communications device to

determine when motion of said portable housing exceeds a first security alert threshold, and send a first security alert message to said vehicle controller based thereon to cause the vehicle controller to generate a first alarm,

determine when the first security alert threshold is exceeded for a predetermined time and enter a power saving mode based thereon; and

a battery carried by said portable housing and powering said motion sensor, second wireless communications device and sensor controller.

15. The wireless security sensor of claim 14 wherein said at least one wireless security sensor has a unique identifier (UID) associated therewith.

16. The wireless security sensor of claim 15 wherein said sensor controller is switchable to a learning mode to send the UID to the vehicle controller.

17. The wireless security sensor of claim 14 wherein said sensor controller generates a low battery message including a UID associated with the wireless security sensor.

18. The wireless security sensor of claim 14 wherein said sensor controller is further configured to determine when motion is above a second security alert threshold lower than the first security alert threshold and send a second security alert message to the first wireless communications device based thereon;

and wherein the vehicle controller is configured to generate a second alarm responsive to the second security alert message.

19. The wireless security sensor of claim 14 wherein said motion sensor comprises a three dimensional (3D) accelerometer.

20. The wireless security sensor of claim 14 wherein said motion sensor comprises a tilt sensor.

21. A method for using a vehicle security system comprising a vehicle controller carried by a vehicle and a first wireless communications device carried by the vehicle and coupled to the vehicle controller, the method comprising:

positioning at least one wireless security sensor at the vehicle, the at least one wireless security sensor comprising a portable housing, a motion sensor carried by the portable housing to detect motion thereof, a second wireless communications device carried by the portable housing to communicate with the first wireless communications device, a sensor controller carried by the portable housing and coupled to the motion sensor and the second wireless communications device, and a battery carried by the portable housing and powering the motion sensor, the second wireless communications device, and the sensor controller;

using the sensor controller to determine when motion of the portable housing exceeds a first security alert threshold based upon the motion sensor, and to send a first security alert message to the vehicle controller based thereon via the second wireless communications device;

using the sensor controller to determine when the first security alert threshold is exceeded for a predetermined time based upon the motion sensor, and enter a power saving mode based thereon; and

generating a first alarm using the vehicle controller responsive to the first security alert message.

22. The method of claim 21 wherein the at least one wireless security sensor has a unique identifier (UID) associated therewith.

23. The method of claim 22 further comprising switching the sensor controller to a learning mode to send the UID to the vehicle controller.

24. The method of claim 22 wherein the at least one wireless security sensor comprises a plurality thereof.

25. The method of claim 24 further comprising:
