摘要:
The invention provides a wind turbine generating apparatus capable of controlling a temperature in a rotor head. In a wind turbine generating apparatus in which a driving/generating mechanism coupled to a rotor head having wind turbine blades attached thereto is housed in a nacelle, and control devices are housed in a hub of the rotor head, an air circulation guide is provided for allowing air to circulate between an inside of the rotor head and an inside of the nacelle via a communication path formed between the rotor head and the nacelle.

An object detection system includes a radar detection portion that detects first lateral position information relating to the lateral position of an object with respect to a host vehicle, by transmitting a transmission wave and receiving a reflection wave reflected by the object; an image detection portion that detects second lateral position information relating to the lateral position of the object with respect to the host vehicle, based on the captured image of the object; a distance detection portion that detects a distance between the host vehicle and the object; and a lateral position estimation portion that estimates the lateral position of the object based on the first lateral position information and the second lateral position information. When the lateral position of the object is estimated, the lateral position estimation portion changes each of a weight assigned to the first lateral position information and a weight assigned to the second lateral position information according to the distance.

摘要:
Provided is an object detector capable of setting an appropriate image processing area even when the behavior of a host vehicle is changed. The object detector performs image processing on a specific image processing area of a captured image of the surroundings of a host vehicle and acquires information on an object in the surroundings of the host vehicle. The object detector includes a millimeter-wave sensor (2) and an ECU (4) that acquire position information of an object in the surroundings of the host vehicle and a camera (3) that captures an image of the surroundings of the host vehicle. The object detector sets an image processing area in an image captured by the camera (3) based on the position information of the object acquired by the millimeter-wave sensor (2) and the ECU (4), detects a change in the behavior of the host vehicle, and corrects the set image processing area in accordance with the detected change in the behavior of the host vehicle.
