Restraint control systems and methods

1. A restraint control system of a vehicle, comprising:

a position module configured to determine positions of two or more seats within a passenger cabin of the vehicle,

wherein the seats are engaged with pairs of tracks on a floor of the passenger, the pairs of tracks arranged parallel to a longitudinal axis of the vehicle, and sets of two or more seats are disposed on each pair of tracks;

a restraint control module configured to, in response to detection of a collision of the vehicle:

select which ones of the restraints of the vehicle to activate based on the positions of the seats;

activate the selected restraints of the vehicle; and

not activate non-selected ones of the restraints.

2. The restraint control system of claim 1 wherein the position module is configured to determine the positions of the seats based on output from sensors configured to generate the output based on movement of the seats along the pairs of tracks.

3. The restraint control system of claim 1 wherein the position module is configured to determine the positions of the seats based on signal strength indicators of radio frequency (RF) signals transmitted and received within the passenger cabin.

4. The restraint control system of claim 1 wherein the position module is configured to determine the positions of the seats based on one or more images of the passenger cabin captured using one or more cameras.

5. The restraint control system of claim 1 wherein the restraint control module is configured to select which restraints of the vehicle to activate further based on a location of the collision.

6. The restraint control system of claim 1 wherein the restraints include at least airbags and seatbelt pretensioners.

7. The restraint control system of claim 1 wherein the restraint control module is configured to select which restraints of the vehicle to activate further based on directions that the seats are facing.

8. The restraint control system of claim 1 wherein the restraint control module is configured to select which restraints of the vehicle to activate further based on indicators of whether the seats, respectively, are occupied or not.

9. The restraint control system of claim 1 wherein the restraint control module is configured to select which ones of the restraints of the vehicle to activate using a lookup table that relates seat positions, seat directions, seat occupancy, and collision location to restraints to select.

10. A restraint control method for a vehicle, comprising:

by one or more processors, determining positions of two or more seats within a passenger cabin of the vehicle,

wherein the seats are engaged with pairs of tracks on a floor of the passenger, the pairs of tracks arranged parallel to a longitudinal axis of the vehicle, and sets of two or more seats are disposed on each pair of tracks;

in response to detection of a collision of the vehicle, by the one or more processors:

selecting which ones of the restraints of the vehicle to activate based on the positions of the seats;

activating the selected restraints of the vehicle; and

not activating non-selected ones of the restraints.

11. The restraint control method of claim 10 wherein determining the positions of the seats includes determining the positions of the seats based on output from sensors configured to generate the output based on movement of the seats along the pairs of tracks.

12. The restraint control method of claim 10 wherein determining the positions of the seats includes determining the positions of the seats based on signal strength indicators of radio frequency (RF) signals transmitted and received within the passenger cabin.

13. The restraint control method of claim 10 wherein determining the positions of the seats includes determining the positions of the seats based on one or more images of the passenger cabin captured using one or more cameras.

14. The restraint control method of claim 10 wherein selecting which restraints of the vehicle to activate includes selecting which restraints of the vehicle to activate further based on a location of the collision.

15. The restraint control method of claim 10 wherein the restraints include at least airbags and seatbelt pretensioners.

16. The restraint control method of claim 10 wherein selecting which restraints of the vehicle to activate includes selecting which restraints of the vehicle to activate further based on directions that the seats are facing.

17. The restraint control method of claim 10 wherein selecting which restraints of the vehicle to activate includes selecting which restraints of the vehicle to activate further based on indicators of whether the seats, respectively, are occupied or not.

18. The restraint control method of claim 10 wherein selecting which restraints of the vehicle to activate includes selecting which restraints of the vehicle to activate using a lookup table that relates seat positions, seat directions, seat occupancy, and collision location to restraints to select.
