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： A plurality of ultrasonic sensors is provided in both front and rear bumpers of a vehicle to detect obstacles around the vehicle. Each sensor sets up a transmission frequency of an ultrasonic pulse signal that should be set up in a frequency adjustment circuit and a center frequency in filter processing in a filter circuit in response to a frequency setting frame transmitted from an EMU. The EMU stores a combination of the transmission frequency and the center frequency for each ultrasonic sensor.

摘要： An ultrasonic sensor includes a piezoelectric vibrator, a reverberation measuring device and a compensating device. The piezoelectric vibrator vibrates to transmit an ultrasonic wave, receives a reflected wave of the transmitted ultrasonic wave and produces an output signal corresponding to vibration of the piezoelectric vibrator. The reverberation measuring device measures a reverberation period of the piezoelectric vibrator from the output signal. The compensating device compensates for an operation characteristic of the piezoelectric vibrator in accordance with the measured reverberation period. Thus, the ultrasonic sensor can decrease a reverberation period, which may cause reduction in detection accuracy and impossibility of detection of an obstacle at a short distance.
