Abstract: An image processing unit identifies the shape of an obstacle that is identified from an area that appears in a peripheral image based on an image captured by a camera. The shape of the obstacle includes at least a tilt of a section of the obstacle in a road-surface direction. The section of the obstacle faces a vehicle. The image processing unit generates a superimposed image in which a mark image that is generated as a pattern that indicates the identified obstacle is superimposed onto a position that corresponds to the obstacle in the peripheral image. At this time, the image processing unit variably changes properties of the mark image based on the tilt of the obstacle identified by an obstacle identifying unit. The image processing unit then displays the generated superimposed image on display apparatus.

Abstract: An object detection device comprises a transmission sound pressure adjustment unit adjusting a sound pressure of the search wave so that the sound pressure of the search wave or a reflected wave based on the search wave is within a predetermined transmission target range.

The transmission sound pressure adjustment unit is configured to adjust the sound pressure of each of the first and second search waves so that the sound pressure of the corresponding one of the first and second search waves or the reflected wave based on the corresponding one of the first and second search waves is within the transmission target range.

Abstract: In an object detection device to be installed to a vehicle and detect an object outside the vehicle, a position calculator sets multiple candidate points representing a candidate position of the object, based on positions of feature points extracted from a first image captured at a first time. The multiple candidate points are set to be denser within a detection range set based on a distance to the object detected by the ultrasonic sensor than outside the detection range. The position calculator estimates positions of the multiple candidate points at a second time which is after the first time, based on the positions of the multiple candidate points and movement information of the vehicle, and calculates the position of the object by comparing the estimated positions of the multiple candidate points at the second time and the positions of the feature points extracted from a second image captured at the second time.

Abstract: An object detection device which determines an amplitude Ar of an ultrasonic wave received by a receiving unit, detects a frequency fr of the ultrasonic wave, sweeps a frequency fp of a pulse signal after a predetermined time has elapsed from start of generation of the pulse signal, and determines that the received ultrasonic wave is a reflected wave of the probe wave when the frequency fr after the amplitude Ar becomes a predetermined reference value or more from start of transmission of the probe wave makes the same change as the frequency fp. When an ultrasonic wave received by a receiver is determined to be a reflected wave of the probe wave, the object detection unit calculates a distance to an object based on a time from transmission of the probe wave to reception of the ultrasonic wave.

Abstract: An ECU of an object detection device stops transmission of search waves from a plurality of ultrasonic sensors when a vehicle travels at a predetermined speed or more, and counts the frequency of receiving waves with an intensity of not less than a threshold intensity for each of the plurality of ultrasonic sensors. The ECU acquires a first count that is a count of the frequency in a first sensor that is one of the plurality of ultrasonic sensors, and a second count that is a count of the frequency in a second sensor different from the first sensor. The ECU determines that snow accretion has occurred on the first sensor if the first count is smaller than the second count, and a difference between the first count and a representative value that is set based on the second count is not less than a predetermined value.

Abstract: An ECU is applied to a vehicle system that is provided with lateral sensors which acquire distance information expressing a distance to an object that is located at a position on a lateral side of a vehicle. When distance information on the object is acquired by the lateral sensors, a judgement is made by the ECU as to whether or not the object is a predetermined moving object that moves relative to the vehicle. The ECU determines that the object is a target to be subjected to contact avoidance processing for avoiding contact with the object, based on a result of judging whether or not the object for which the distance information is acquired is a moving object.
