A first-collision-situation determining part determines a position of a head of the human and a relative speed of the head relative to the vehicle at a time of the first collision, when the first-collision predicting part determines the possibility of the first collision is higher than the predetermined threshold. A second-collision-situation estimating part estimates a collision situation of the head in a second collision, based on a determining result of the first-collision-situation determining part. An injury-degree predicting part predicts a degree of injury of the head based on an estimation result of the second-collision-situation estimating part. ## Claims ### Claim 1 An impact-injury predicting system, comprising: an image sensor detecting a human in front of a vehicle in a front-rear direction of the vehicle, wherein the image sensor detects a position of a head of the human, a relative speed of the head relative to the vehicle in a left-right direction of the vehicle, and a relative speed of the head relative to the vehicle in a perpendicular direction perpendicular to the front-rear direction and the left-right direction; a distance sensor detecting a relative speed and a relative distance of the human, who is detected by the image sensor, relative to the vehicle in the front-rear direction; a first-collision predicting part determining if a possibility of a first collision, which happens between the human and the vehicle, is higher than a predetermined threshold based on a detection result of the image sensor and a detection result of the distance sensor; a first-collision-situation determining part determining a position of the head and a relative speed of the head relative to the vehicle at a time of the first collision based on the detection result of the image sensor and the detection result of the distance sensor, when the first-collision predicting part determines the possibility of the first collision is higher than the predetermined threshold; a second-collision-situation estimating part estimating a collision situation of the head in a second collision, based on a determining result of the first-collision-situation determining part; and an injury-degree predicting part predicting a degree of injury of the head based on an estimation result of the second-collision-situation estimating part. ### Claim 2 (depends on 1) The impact-injury predicting system according to claim 1, wherein the second-collision-situation estimating part estimates an impact site of the head with the vehicle and an impact speed of the head relative to the vehicle at the time of the second collision. ### Claim 3 (depends on 1) The impact-injury predicting system according to claim 1, further comprising: a collision-detecting sensor detecting a collision of the vehicle; and a collision determining part determining if a collision happens or not based on a detection result of the collision-detecting sensor, wherein the second-collision-situation estimating part determines that the estimation result of the second-collision-situation estimating part is effective, when the collision determining part determines the collision of the vehicle. ### Claim 4 (depends on 1) The impact-injury predicting system according to claim 1, further comprising: a collision-detecting sensor detecting a collision of the vehicle; a collision determining part determining if a collision happens or not based on a detection result of the collision-detecting sensor; a first protection device mounted in a front part of the vehicle to absorb an impact of a collision between the human and an internal combustion engine of the vehicle; a second protection device mounted in a front part of the vehicle to absorb an impact of a collision between the human and a pillar of the vehicle; and a protection device controller selectively actuates the first protection device or the second protection device based on the estimation result of the second-collision-situation estimating part, when the collision determining part determines the collision of the vehicle. ### Claim 5 (depends on 4) The impact-injury predicting system according to claim 4, wherein the injury-degree predicting part predicts the degree of injury of the head based on the estimation result of the second-collision-situation estimating part and a control result of the protection device controller. ### Claim 6 (depends on 1) The impact-injury predicting system according to claim 1, further comprising: a collision-detecting sensor detecting a collision of the vehicle; a collision determining part determining if a collision happens or not based on a detection result of the collision-detecting sensor; and a wireless communication device reporting a prediction result of the injury-degree predicting part to an institution, when the collision determining part determines the collision of the vehicle. ### Claim 7 (depends on 1) The impact-injury predicting system according to claim 1, wherein the second-collision-situation estimating part estimates an impact speed of the head relative to the ground, when the second-collision-situation estimating part estimates that the second collision does not happen between the head and the vehicle.
