Abstract

Methods of activating protection devices in a motor vehicle are provided. The method involves monitoring for objects in the environment of the vehicle and for impact events involving the vehicle, evaluating data based on the monitoring activities, formulating an activation plan based on the data evaluation, and activating the protection devices. The invention allows activation decisions that are based on evaluation of data relating to both impact events and the surrounding environment.

Claims

1. A method of activating one or more protection devices in a motor vehicle, comprising:

providing an impact sensor adapted to detect an impact event involving said vehicle;

providing a remote sensing device adapted to gather information about objects in the environment of said vehicle;

providing a control module operably connected to the remote sensing device, impact sensor, and said protection devices;

transmitting a first data set from the impact sensor to the control module;

transmitting a second data set from the remote sensing device to the control module;

evaluating the first and second data sets in consideration of each other;

formulating an activation plan that contains an activation signal for each of said protection devices; and

activating said protection devices in accordance with the activation plan.

2. A method in accordance with claim 1, wherein at least one of said protection devices comprises a resettable protection device and further comprising resetting the resettable protection device.

3. A method in accordance with claim 1, wherein the first data set comprises data related to an impact event detected by the impact sensor.

4. A method in accordance with claim 3, wherein the data includes information related to one or more of the location of the impact event, angle of the impact event, mass of object impacting said motor vehicle in the impact event, and severity of the impact event.

5. A method in accordance with claim 1, wherein the second data set comprises data related to objects within the environment of said vehicle.

6. A method in accordance with claim 5, wherein the data includes information related to the range or azimuth of an object relative to a reference point.

7. A method in accordance with claim 6, wherein the reference point comprises the location at which the remote sensing device is located on the vehicle.

8. A method in accordance with claim 1, wherein transmitting a first data set and transmitting a second data set is repetitively performed at an interval of time.

9. A method in accordance with claim 8, wherein the interval of time comprises a regular interval of time.

10. A method in accordance with claim 9, wherein the interval of time comprises 20 milliseconds.

11. A method in accordance with claim 1, wherein at least one activation signal represents a desired degree of activation of an appropriate one of said protection devices.

12. A method of activating one or more protection devices in a motor vehicle having an impact sensor outputting a first data set related to an impact event involving said motor vehicle, and a remote sensing device outputting a second data set related to objects within the environment of said vehicle, the method comprising:

evaluating the first and second data sets in consideration of each other;

formulating an activation plan that contains an activation signal for each of said protection devices; and

activating said protection devices in accordance with the activation plan.

13. A method in accordance with claim 12, wherein the evaluating the first and second data sets in consideration of each other is conducted by a control module operably connected to said impact sensor, said remote sensing device, and said protection devices.

14. A method in accordance with claim 12, wherein the evaluating the first and second data sets is repetitively performed at an interval of time.

15. A method in accordance with claim 14, wherein the interval of time comprises a regular interval of time.

16. A method in accordance with claim 15, wherein the interval of time comprises 20 milliseconds.

17. A method of activating one or more protection devices in a motor vehicle comprising:

monitoring for objects in the environment of said motor vehicle;

monitoring for impact events involving said motor vehicle;

transmitting a first data set relating to the monitoring for objects;

transmitting a second data set relating to the monitoring for impact events;

evaluating the first and second data sets in consideration of each other;

formulating an activation plan that contains an activation signal for each of said protection devices; and

activating said protection devices in accordance with the activation plan.

18. A method in accordance with claim 17, wherein the first data set includes information related to one or more of the impact event, angle of the impact event, mass of object impacting said motor vehicle in the impact event, and severity of the impact event.

19. A method in accordance with claim 17, wherein the first data set includes information related to the range or azimuth of an object relative to a reference point.

20. A method in accordance with claim 19, wherein the reference point comprises the location at which the remote sensing device is located on the vehicle.

21. A method in accordance with claim 17, wherein the monitoring for objects and monitoring for impact events are conducted at a regular interval.

22. A method in accordance with claim 20, wherein the interval is 20 milliseconds.

23. A method in accordance with claim 17, wherein the transmitting a first data set and transmitting a second data set are conducted at a regular interval.

24. A method in accordance with claim 22, wherein the interval is 20 milliseconds.
