Abstract
An object detection device includes an acquisition circuit, a calculation circuit, and an estimation circuit. The acquisition circuit acquires elapsed times from when an ultrasonic wave is transmitted from a transmission microphone to when reception microphones each receive the ultrasonic wave. The calculation circuit calculates a wind speed on the basis of the elapsed times acquired by the acquisition circuit. The estimation circuit estimates a vehicle state on the basis of the wind speed calculated by the calculation circuit.
Claims19
An object detection device configured to be mounted on a vehicle, the object detection device comprising:
- an acquisition circuit which, in operation, acquires elapsed times from when an ultrasonic wave is transmitted from a transmission microphone to when reception microphones each receive the ultrasonic wave;
- a calculation circuit which, in operation, calculates a wind speed based on the elapsed times acquired by the acquisition circuit;
- and
- an estimation circuit which, in operation, estimates a traveling direction of the vehicle based on the wind speed calculated by the calculation circuit.
An object detection method by an object detection device configured to be mounted on a vehicle, the method comprising:
- acquiring elapsed times from when an ultrasonic wave is transmitted from a transmission microphone to when reception microphones each receive the ultrasonic wave;
- calculating a wind speed based on the elapsed times acquired by the acquiring;
- and
- estimating a traveling direction of the vehicle based on the wind speed calculated by the calculating.
A non-transitory computer-readable recording medium on which programmed instructions are recorded, the programmed instructions causing a computer configured to be mounted on a vehicle to execute processing, the processing comprising:
- acquiring elapsed times from when an ultrasonic wave is transmitted from a transmission microphone to when reception microphones each receive the ultrasonic wave;
- calculating a wind speed based on the elapsed times acquired by the acquiring;
- and
- estimating a traveling direction of the vehicle based on the wind speed calculated by the calculating.
