A device for adjusting a view range of a vehicular monitoring device includes
an
overtaking pre-motion detector outputting an adjusting signal when an overtaking
operation is predicted; and a controller in communication with the overtaking pre-motion
detector and the vehicular monitoring device, controlling the vehicular monitoring
device to move in response to the adjusting signal. The device may further output
a warning signal to sound the horn or twinkle the vehicle lamp when the overtaking
operation is predicted for safety consideration.
