[0025] figure 1 An ultrasonic sensor unit 10 is shown as an obstacle detection sensor (hereinafter simply referred to as an ultrasonic sensor) used in the obstacle detection apparatus 1 for a vehicle. The ultrasonic sensor 10 is a two-way sensor that transmits ultrasonic waves by vibrating a piezoelectric ceramic vibrator using a piezoelectric effect, and converts ultrasonic waves incident on the piezoelectric ceramic vibrator into an electric signal. The ultrasonic sensor 10 includes an ultrasonic microphone 11, a housing 12 with an integrated connector 12, and a control circuit board 13.

[0026] The ultrasonic microphone 11 accommodating the piezoelectric ceramic vibrator is housed in the housing 12 through the cushion member 14.

[0027] The housing 12 is integrally assembled to the bumper BP of the vehicle through a spring member (not shown), through a vessel 15 having a ring-shaped rim. The housing 12 is sealed by a cover 17, wherein the housing 12 contains an ultrasonic mi...

Abstract

The vehicle-use obstacle detection apparatus having a plurality of obstacle detection sensors installed at different places of a vehicle is configured to control a voice warning device such that, when two or more of the obstacle detection sensors have detected obstacles in succession, voice messages indicative of directions in which the detected obstacles are present respectively are outputted in succession in ascending order of value of the obstacle distance.

Description

Technical field [0001] The present invention relates to an obstacle detection device for a vehicle, which has a voice alarm function for outputting an alarm by voice according to the position of the detected obstacle. Background technique [0002] An obstacle detection device for a vehicle is known, which includes: four ultrasonic sensors arranged in different places of the vehicle, configured to transmit ultrasonic waves and receive ultrasonic waves reflected from obstacles; and a processing unit that transmits and receives ultrasonic waves based on the ultrasonic sensor The ultrasonic wave calculates the distance from the detected obstacle; the voice alarm unit, which outputs a warning voice message about the direction of the obstacle when the distance from the obstacle becomes less than a predetermined distance; and a control device for controlling the voice Alarm Department. For example, refer to Japanese Patent No. 3550322. [0003] The vehicle obstacle detection device desc...
