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.

Abstract: A parking assistance device is applied to a vehicle equipped with a camera for capturing an image of an area in front of the vehicle and is configured to assist forward parking of the vehicle in a parking space. The parking assistance device includes: a position estimation unit which, in a situation where the vehicle is advancing toward the parking space in a lateral passage of the parking space, estimates, based on an image captured by the camera, at least one of a first corner position, which is a near-side corner position at a vehicle entrance part of the parking space, and a second corner position, which is a far-side corner position at the vehicle entrance part, before the vehicle passes by the parking space; and a space recognition unit which recognizes the parking space for forward parking based on the at least one estimated corner position.

Abstract: In a sensor system, a monitoring ECU includes a result-transmission-instruction transmission section that transmits through a signal line a measurement result transmission instruction for transmitting distance data. The result-transmission-instruction transmission section transmits, during a new detection operation, the measurement result transmission instruction to at least one of the ultrasonic sensors engaged in a last detection operation. Upon receipt of the measurement result transmission instruction, a communication section of the ultrasonic sensors transmits a detection result during the new detection operation.

Abstract: A protective cover protects a connector coupling portion which is an electrical connection between an on-vehicle sensor to be mounted on a vehicle body component and a wiring. This protective cover includes a protection portion and a fixing portion. The protection portion covers the connector coupling portion at which a sensor-side connector which is provided on the on-vehicle sensor side and which extends in an extending direction is coupled to a wiring-side connector which is provided on the wiring side and which is to be coupled to the sensor-side connector while moving relatively with respect to the sensor-side connector in a coupling direction opposite to the extending direction. The fixing portion is integrally provided with the protection portion so as to be fixed on the on-vehicle sensor side.

Abstract: A retainer member is equipped with a microphone facing portion, a drain path, and a stamped wall portion. The microphone facing portion is formed in a cylindrical shape matching an ultrasonic microphone is disposed outside the ultrasonic microphone in a radial direction extending radially from a longitudinal center line. The microphone facing portion extends from a body retaining portion toward a base side in an axial direction. The drain path extends through the microphone facing portion in the radial direction and is capable of discharging water from an inner space in the microphone facing portion. The stamped wall portion is formed in the microphone facing portion and faces the drain path through the longitudinal center line.

Abstract: An object detection device includes: a wave receiver that receives a reflected wave generated by reflection, by an object, of a transmission wave incident on the object; a determination section that determines whether, in a change over time in an amplitude of the reflected wave received by the wave receiver, an amplitude of a falling portion is greater than a predetermined criterion, the amplitude of the falling portion being decreased after the amplitude has reached a maximum value; and a processing section that, on the basis of a determination by the determination section that the amplitude of the falling portion is greater than the predetermined criterion, performs a process in which the object is treated as an object to be avoided.

Abstract: An ultrasonic object detection device includes: a first echo prolongation determination unit that sequentially determines whether a measured echo time of an ultrasonic sensor is prolonged from a reference echo time; a second echo prolongation determination unit that determines whether an addition echo time is prolonged from the reference echo time when the measured echo time is not prolonged from the reference echo time, and the ultrasonic sensor detects a reflected wave, the addition echo time being obtained by adding, to the measured echo time, a time from termination of an echo to termination of a first reflected wave; and a short distance object detection unit that determines that an object is disposed within a short distance so as to receive the reflected wave while the echo is not terminated when one of the measured echo time or addition echo time is prolonged from the reference echo time.

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.
