摘要： 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.

摘要： An obstacle detection apparatus includes: a transceiver transmitting a transmission wave and receiving an ultrasonic wave; a transmission controller; a receiver circuit detecting a signal level of a receiving wave; a distance calculator sequentially calculating a distance to an object reflecting the transmission wave; a memory storing the distance to the object; an obstacle determination device determining whether the object is an obstacle; and a reception level monitoring device monitoring the signal level of the receiving wave before the transmission wave being transmitted. When the signal level exceeds a predetermined threshold, the obstacle determination device sets a first number of determination data elements to an increased number of determinations for a predetermined period to be used for determining whether the object is the obstacle, as being larger than a second number of determination data elements used when the signal level does not exceed the predetermined threshold.

摘要： An object detection apparatus is arranged to detect the distance to the object and includes: a transceiver repeatedly transmitting a wave as an ultrasonic wave and receives a reflection wave of the transmission wave; a transmission controller controlling the transceiver to transmit the transmission wave; a distance calculator calculating a distance to the object, based on a time interval from a moment when the transceiver transmits the wave to a moment when the reflection wave is received; and a transmission timing controller controlling timing at which the transmission controller controls the transmission wave to be transmitted. Moreover, the transmission timing controller inserts at least one type of temporary waiting time between a transmission/reception period in which the transceiver transmits the transmission wave and receives the reflection wave and a next transmission/reception period, when a predetermined crosstalk identification condition is established based on the distance to the object.

摘要： An ultrasonic type object detection apparatus sequentially detects a distance between an ultrasonic sensor and an object in a coverage of a transmission wave at a predetermined detection cycle based on a time taken for the ultrasonic sensor to transmit the transmission wave and then to receive a reflection wave. The apparatus includes: a storage storing the distance to the object; a vehicle information acquisition device acquiring vehicle information for calculating a movement distance; a detection distance predictor predicting a next detected distance to the object based on a past detection result and the vehicle information; and a short range determinator determining whether the object is present in a short range area in which the distance between the object and the ultrasonic sensor is equal to or shorter than a short range threshold.

摘要： An obstacle detection apparatus for vehicles includes: a first ultrasonic sensor for detecting a distance to an obstacle; a second ultrasonic sensor at a position of the vehicle for receiving a reflection wave from the obstacle of an ultrasonic wave from the first ultrasonic wave; a notifier that gives a notification of detecting the obstacle present within a preset distance in one or more of predetermined notification areas including a first notification area for the first ultrasonic sensor, and a second notification area for the second ultrasonic sensor detects the obstacle for the vehicle; and a controller that controls contents to be notified by the notifier. Furthermore, the controller determines whether a first indirect wave distance and a second indirect wave distance are used to determine whether to give the notification of detecting the obstacle in the first notification area.
