  • Distance measuring apparatus and distance measuring method
    Patent number: 9519053
    Abstract: A distance measuring apparatus and a distance measuring method are provided. The distance measuring apparatus includes a GPS module, an ultrasound transceiver module and a control module. The GPS module is configured to generate a pulse signal. The ultrasound transceiver module is configured to generate and transmit a first ultrasound signal and receive a second ultrasound signal transmitted from an object. When the control module receives the pulse signal, the control module controls the ultrasound transceiver module to generate and transmit the first ultrasound signal, and determines whether the ultrasound transceiver module receives the second ultrasound signal within a first interval. When the ultrasound transceiver module receives the second ultrasound signal within the first interval, the control module determines a distance between the distance measuring apparatus and the object according to a time difference.
