    Abstract: PROBLEM TO BE SOLVED: To provide a pedestrian detection device which can improve the detection accuracy of a pedestrian in the night or the like. SOLUTION: The pedestrian detection device is provided with an infrared radiation emitting portion 14 emitting infrared radiation, and an infrared radiation camera 16 photographing images of an infrared radiation image. A controller 12 extracts a candidate of a retina reflection point of a pedestrian based on the infrared radiation image photographed by the infrared radiation camera 16, and determines whether or not a pedestrian exists in the infrared radiation image based on a position of the candidate of the extracted retina reflection point.

    Abstract: PROBLEM TO BE SOLVED: To prevent a pedestrian riding on a hood 7 at a front of a vehicle from moving to the front of the hood 7 accompanying with braking of the vehicle and dropping on a road face from the hood 7, when the traveling vehicle collides with the pedestrian as a collided body. SOLUTION: This device is equipped with a position detecting sensor 5 for measuring a distance to the position detecting sensor 5 from a pedestrian entering onto the hood 7 due to collision with the vehicle, and an ECU 2 detects whether the pedestrian moves in a forward direction of the hood 7 by an inertia generated at the time of braking the vehicle based on position detecting signals detected by the position detecting sensor 5. When the ECU 2 detects the movement of the pedestrian in the forward direction of the hood 7, braking force indication signals are given to a braking force controlling device 3 to reduce the braking force of the vehicle and the braking force of the vehicle is reduced, so as to prevent the pedestrian on the hood 7 from moving in the forward direction of the hood 7. This can prevent the pedestrian from dropping onto the road face from the hood 7 together with the forward movement of the hood 7. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To sufficiently protect a pedestrian by flipping up a vehicular hood at the time of collision with the pedestrian. SOLUTION: When the collision with the pedestrian is detected or expected by detection signals from a millimeter wave radar, an image sensor, and a load sensor, a flip-up actuator 16 is actuated to operate link mechanisms 12, 13, thereby flipping up the hood 11. Concerning flipping up of the hood 11, flip-up position adjusting actuators 21, 22 are controlled according to the traveling speed of a vehicle and the height of the pedestrian, so that the faster the traveling speed of the vehicle is and the larger the height of the pedestrian is, the larger the hood is flipped up backward.

    Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy for a human-body-exposed target in a vehicle target detection system. SOLUTION: A radar apparatus repeats the detection of up to m pieces of weak reflection targets, which is located in front of a vehicle, of which the reflection intensity is not higher than a threshold th2 and is not lower than a threshold th3, and of which the distance is within a predetermined value Ds, on a cycle of T 2 and repeats the detection of up to n strong reflection targets, which is located in front of the vehicle and of which the reflection intensity is higher than a vehicle detection threshold th1 on a cycle of T 1 (T 2 ≪T 1 ). An image processing apparatus repeats the extraction of edges obtained by excluding road edges from an image obtained by photographing scenery in front of the vehicle. Target information is received from the radar apparatus, while edge information is received from the image processing apparatus (110, 112). On the basis of whether an edge is present at the mapping position of each weak reflection target on the image represented by the received target information, the presence or absence of the entity of each weak reflection target is decided, and the entity is decided to be present.
