Abstract
An active distance measuring device includes a detection wave transmitter, a reflected wave receiver and a controller. The detection wave transmitter is configured to transmit the detection wave with a designated transmission power to be reflected to form a reflected wave. The reflected wave receiver is configured to operate at a designated detection power to receive the reflected wave and generate reflected wave information accordingly. The controller is electrically connected to the detection wave transmitter and the reflected wave receiver, to control the detection wave transmitter to transmit the detection wave and receive the reflected wave information, so as to obtain distance information based on a transmission state of the detection wave and the reflected wave information. The controller is further configured to receive a vehicle speed signal to adjust the designated transmission power and designated detection power according to the vehicle speed signal.
