Original Abstract Submitted

a object detection device for a vehicle, in which sonars a and c simultaneously transmit sound waves and receive direct waves reflected by objects; a sonar b positioned between the sonars a and c receives indirect waves reflected by the objects; and, when, in a situation where the sonars a and c receive the direct waves and the sonar b receives one indirect wave, a peak value of the indirect wave received by the sonar b is greater than or equal to a predetermined multiplication with respect to peak values of the direct waves received by the sonars a and c, an electronic control unit estimates positions of the objects in detection areas of the sonars a and c based on a flight time of the direct waves received by the sonars a and c, respectively and a flight time of the indirect wave received by the sonar b.
