Ultrasonic sensor
First Claim
1. An ultrasonic sensor adapted to be provided at a flip-up back door that opens and closes via a pivot shaft provided at a rear top of a vehicle, a surface of the back door being included in a detection range of the ultrasonic sensor, the ultrasonic sensor detecting an object in a vicinity of the vehicle by intermittently transmitting an ultrasonic wave, which hits the object to thereby generate a reflected wave as a reflection of the ultrasonic wave, the ultrasonic sensor comprising:
- a sensor head provided at the back door and including a transmitter transmitting the ultrasonic wave and a receiver receiving the reflected wave, wherein the sensor head is provided at a position in a vicinity of a centerline of the vehicle in a width direction thereof and where a distance from a corner of a distal end edge portion of the back door to the sensor head is shorter than a distance from the sensor head to a small aboveground structure provided on the ground.

8. An ultrasonic sensor adapted for being provided at a flip-up back door which is pivoted to a rear-top of a vehicle for covering a surface of the flip-up back door and serving for detecting an object in a vicinity of the vehicle by transmitting ultrasonic waves intermittently to an object and receiving the reflected ultrasonic waves therefrom, the ultrasonic sensor comprising:
-
a sensor head including a transmitter transmitting the ultrasonic waves and a receiver receiving the reflected waves, the sensor head being provided at a position in a vicinity of a lateral directional centerline of the vehicle in such manner that a distance from a corner edge of a distal end portion of the back door to the sensor head is shorter than a distance from the sensor head to a small aboveground structure near the vehicle. - View Dependent Claims (9, 10, 11, 12, 13)
