摘要： An apparatus for detecting an object approaching a vehicle by performing image recognition processing on an image captured by a camera that is mounted on the vehicle to cover a predetermined area around the vehicle includes a signal receiver, a selector, and a detector. The signal receiver obtains a vehicle signal indicative of an operating condition of the vehicle. The selector selects a predetermined region of the captured image, according to the vehicle signal, as an object detection region. The detector detects the object approaching the vehicle by performing the image recognition processing on only the object detection region of the captured image.

摘要： A device for detecting an obstacle located backward of a vehicle is mounted on a vehicle such as a pickup truck having a rear loading space and a tailgate for closing the loading space. Ultrasonic waves are transmitted backward, and the backward obstacle is detected by receiving ultrasonic waves reflected by the backward obstacle. When the tailgate is open or the load extends backward from the open tailgate, the transmitted waves are reflected by the open tailgate or the extending load. This may cause erroneous detection of the backward obstacle. To avoid the erroneous detection, detection of the reflected waves from the backward obstacle is delayed by a predetermined period when the tailgate is open or the load extends backward.

摘要： An object detecting apparatus includes a sensor, a noise determining portion, a detected result determining portion and a warning portion. The sensor transmits an ultrasonic wave and receives a reflected wave reflected by an object. The noise determining portion determines existence or nonexistence of a noise signal received by the sensor for a plurality of detecting areas by using a different threshold value for each of the plurality of detecting areas. The detected result determining portion validates or invalidates an object detected result of the sensor for each of the detecting areas based on existence or nonexistence of the noise signal determined by the noise determining portion for each of the detecting areas. The warning portion warns about the object detected result for a detecting area that is validated by the detected result determining portion.

摘要： During a period until a subject vehicle stops to go back for being parked, detection distance data items and advance distance data items are obtained by using an ultrasonic sensor and a speed sensor. These data items are stored with both the data items mutually associated. The detection distance data item indicates a distance to a parked vehicle adjacent to the subject vehicle and the advance distance data item indicates a distance in which the subject vehicle advances. When computing a size of the parked vehicle from the advance distance data items, the size of the parked vehicle is determined to be shorter than an aggregated distance corresponding to the advance distance data items. This enables the determined size of the parked vehicle to approximate an actual size of the parked vehicle.
