摘要： An obstacle detection device has detection units, each of which performs a signal transmission-reception operation for sending detection signal to a detection area allotted thereto and receiving reflection signal from the detection area, an operation control unit for controlling the detection unit so that the detection unit performs the signal transmission-reception operation responding to at least one of a plurality of kinds of operation timing signals repeated at a predetermined periodicity, and a determination unit which counts a number of continuous reception times of the reflection signal of the detection unit and determines an obstacle detection in the detection area when the number of the continuous reception times thereof is larger than or equal to a predetermined value. The transmission-reception operation of the detection unit which commenced to receive the reflection signal is provided by the operation control unit with the operation timing signal having a periodicity shorter than the predetermined periodicity.

摘要： A pair of distance measurement sensors provided at different heights measures distances to an obstruction. When the measured distances are shorter than a threshold distance, the height of the vehicle is found based on the measured distances. When the height of the vehicle is found greater than a threshold height, the existence of the obstruction is reported to the driver. When the height of the vehicle is found smaller than the threshold height, on the other hand, a change in obstruction height is found and compared with a threshold. When the change in obstruction height is greater than the threshold, the existence of the obstruction is reported to the driver since the height is determined to be an unreliable result of computation.

摘要： In an apparatus for detecting a distance and improving the SN ratio of received signals, an angular frequency (ω1) of sinusoidal wave signals generated by a sinusoidal wave generator is brought into synchronism with an angular frequency (ω) of burst pulse signals, and signals received by a transmitter/receiver microphone are orthogonally demodulated by using sinusoidal wave signals of the synchronized angular frequency. A microcomputer adds up the vectors of the demodulated signals for only a period of time equal to a section of transmitting the transmission waves from the transmitter/receiver microphone. A distance to a body is detected by using the received signals of which the vectors are added up.

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： Each of plural detection units performs a signal transmission-reception operation responding to at least one of a plurality of kinds of operation timing signals repeated at a predetermined periodicity. The number of continuous reception times of the reflection signal is counted and used to determine obstacle detection when the number of counts is larger than or equal to a predetermined value.
