Wire collision sensor system
First Claim
1. A wire collision sensor system for a vehicle, which includes a vehicle body, the wire collision sensor system comprising:
- a bumper, which is mounted on a longitudinal end portion of the vehicle body;
a wire for sensing a collision of the vehicle, wherein;
the wire is received in the bumper;
the wire extends along the bumper in a transverse direction of the vehicle; and
the wire is connected to at least one of the vehicle body and the bumper at both ends in such a manner that the wire is displaceable in a longitudinal direction of the wire;
a wire deformation sensor for electrically sensing a physical quantity, which is associated with a deformation of the wire at a time of the collision, wherein the wire deformation sensor transmits an output, which indicates the sensed physical quantity;
a determination circuit for determining a state of the collision based on the output, which is transmitted by the wire deformation sensor; and
a slack take-up member, which takes up slack of the wire, wherein;
the slack take-up member displaces the wire in the longitudinal direction of the wire at the time of the collision;
the physical quantity, which is sensed by the wire deformation sensor, is an amount of wire displacement in the longitudinal direction of the wire; and
the wire deformation sensor converts the amount of wire displacement in the longitudinal direction of the wire into an electrical signal.

Abstract
A wire collision sensor system for a vehicle, which includes a vehicle body, includes a bumper, a wire, a wire deformation sensor and a determination circuit. The bumper is mounted on a longitudinal end portion of the vehicle body. The wire, which senses a collision of the vehicle, is received in the bumper and extends along the bumper in a transverse direction of the vehicle. The wire is connected to at least one of the vehicle body and the bumper at both ends in such a manner that the wire is displaceable in a longitudinal direction of the wire. The wire deformation sensor electrically senses a physical quantity, which is associated with a deformation of the wire at a time of the collision. The wire deformation sensor transmits an output, which indicates the sensed physical quantity. The determination circuit determines a state of the collision based on the output.
