摘要： A vehicle periphery monitoring system takes a view image of a vehicle rear periphery, which is in a predetermined area from the vehicle. This view image is converted into a bird's-eye view image and the bird's-eye view image is displayed in a vehicle compartment to assist rearward movement of a vehicle. As the vehicle approaches an obstacle, the bird's-eye view image is formed by increasing an angle of depression of the bird's-eye view image. A masking section is synthesized with the bird's-eye view image to mask a part of the bird's-eye view image not to be viewed. This masking section is increased as the depression angle increases thereby masking the distorted part of the view image.

摘要： An obstacle detection system has multiple ultrasonic sonars. When a threshold value used for determining an existence of an obstacle is compared with a receiving signal having been amplified at a predetermined gain, the sonar having a receiving mode is provided with the gain which is higher than that of the sonar having a sending/receiving mode. Thus, the sensitivity of the sonar having the receiving mode can be improved so that a continuous sound field of the sonar is broadened. Accordingly, the distance of the border of the continuous sound field of the obstacle detection system from the vehicle can become substantially even.
摘要翻译：障碍物检测系统具有多个超声波声纳。当将用于确定障碍物的存在的阈值与已经以预定增益放大的接收信号进行比较时，具有接收模式的声纳被提供有高于具有发送/接收的声纳的增益模式。因此，可以提高具有接收模式的声纳的灵敏度，使得声纳的连续声场变宽。因此，障碍物检测系统的连续声场的边界与车辆的距离可以变得基本上均匀。

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： A field watch apparatus uses a storage unit to store detection data of a detected obstacle from an obstacle sensor that detects objects under control of a control unit, and the detection data accumulated in the storage unit over time is used to display a mark on a captured image that is captured by a camera and shown on a screen of a display unit. The mark size and other attributes of the mark in the image are controlled in a manner that enables a view to easily recognize an old mark from a new one, thereby providing an intuitive recognition of the obstacle movement in a certain direction in the captured image, when the mark is superposed in the captured image for multiple times based on the accumulated detection data in the storage unit.

摘要： An obstacle detection apparatus includes first and second ultrasonic sensors, a control part, and a warning device for warning in accordance with a distance between at least one of the ultrasonic sensors and an obstacle. The control part sets the first ultrasonic sensor to a transmitting and receiving mode while setting the second ultrasonic sensor to a receiving mode, and then sets the first ultrasonic sensor to the receiving mode while setting the second ultrasonic sensor to the transmitting and receiving mode. Each of the ultrasonic sensors has a reception sensitivity to a reflected wave reflected by the obstacle. Each of the ultrasonic sensors includes a reception sensitivity control portion configured to increase the reception sensitivity when the receiving mode is set compared with when the transmitting and receiving mode is set.
