Abstract
A control device of for automatically adjusting a view angle of a rearview mirror of a vehicle is disclosed. The control device includes a turning detector mounted on the vehicle for generating a triggering signal in response to a turning operation of a user; and a drive circuit electrically connected to the turning detector for moving the rearview mirror along a certain direction from an initial position toward a predetermined position in response to the triggering signal. The turning detector, for example, can be an indicator-light switch or a tire-angle switch.
Claims12
A control device for automatically adjusting a view angle of a rearview mirror of a vehicle, comprising:
- a turning detector mounted on said vehicle for generating a first triggering signal in response to a first turning operation of a user;
- a first variable voltage-divider for being adjusted to divide a first constant voltage into a first reference value;
- a second variable voltage-divider outputting a variable voltage value in response to a first movement degree of said rearview mirror;
- a first comparing unit optionally generating a first drive signal in response to a comparing result of said variable voltage value with said first reference value;
- a first controlled switch electrically connected to said first comparing unit and said turning detector, and conducted to output said first drive signal in response to said first triggering signal;
- and
- a first drive circuit electrically connected to said turning detector and said first controller switch, and moving said rearview mirror along a first direction from an initial position toward a predetermined position in response to said first drive signal.
A control device for automatically adjusting a view angle of a rearview mirror of a vehicle, comprising:
- a tire-angle switch mounted on said vehicle for generating a first triggering signal in response to a first turning operation of a tire exceeding a threshold angle;
- a control circuit electrically connected to said tire-angle switch for generating a first drive signal in response to a variable voltage value varying with a first movement degree of said rearview mirror and a first reference value representing a first boundary position of said rearview mirror;
- and
- a first drive circuit electrically connected to said tire-angle switch for moving said rearview mirror along a first direction from an initial position toward said boundary position in response to said first triggering signal and said first drive signal.
