Abstract: An object detection device is provided with a noise state determination unit and a noise information processing unit. The noise state determination unit determines whether a reception state of exogenous noise in an object detecting sensor is a high noise state, while the object detection condition is valid. When it is determined that the noise notification processing unit is a high noise state, noise related notification corresponding to a generation of a restriction in the object detection function as a result of the high noise state is executed. The object detection device provides a difference in the noise related notification depending on a detection state of an object and a running state of an own vehicle.

Abstract: A vehicle-mounted assembly is designed to have a vehicle-mounted device attached to a plate-like vehicle body member with a through hole. The vehicle-mounted device includes a cylindrical member fit in a through-hole and a fastener which secures the cylindrical member to the vehicle body member. The cylindrical member includes a cylindrical main body extending along a center axis line, protrusions protruding from the main body in a direction crossing the center axis line. The fastener is held between the protrusions and the vehicle body member. The through-hole is equipped with a vehicle body joint which engages a device joint made of recessed and raised portions of the cylindrical member. The vehicle body joint is arranged at a given location on an inner circumference of the through-hole around a center of the through-hole.

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 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 ultrasonic sensor, that transmits probe waves which are ultrasonic waves and acquires detection waves including reflected waves which have been reflected from surrounding objects, includes a transmitter/receiver that transmits the probe waves and acquires the detection waves, a detection wave processing section that executes processing for passing a predetermined frequency band which includes the frequency of the probe waves, an amplitude measurement section which measures the amplitude of the detection waves, and a judgement section which judges whether there is adherence of foreign matter on the transmitter/receiver, based on a relationship between a time axis and values of the amplitude of the detection waves during a reverberation interval following the termination of transmitting the probe waves.

Abstract: An object detection device includes a condition judgment unit and a noise processing unit. The condition judgment unit judges whether an execution condition for starting an object detection operation is satisfied. The noise processing unit performs a noise-related notification corresponding to an occurrence of limitation of an object detection function due to a high noise state when the condition judgment unit judges that the execution condition is satisfied and when the high noise state is established, the high noise state being a state in which a reception state of extraneous noise, different from the reflected wave received by the plurality of object detection sensors, exceeds a predetermined judgment criterion. The object detection device is configured to perform the noise-related notification more easily when a driving mode of the own vehicle is a backward driving mode than when the driving mode is a forward driving mode.

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: 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.
