Synchronized rear vision system

A synchronized rear vision system for a vehicle comprising:

• an adjustable driver seat;
• a pair of external side rearview mirrors for attachment to the vehicle;
• an interior rearview mirror for attachment to the vehicle;
• a power driver seat controller communicating with said driver seat;
• and
• a system master controller for:
• detecting an instantaneous position of one of said pair of external side rearview mirrors;
• determining an external side rearview mirror setting method based upon said instantaneous position and a predetermined setting method threshold;
• calculating a first driver's eye position and position output signals for at least another one of said pair of external side rearview mirrors and said interior rearview mirror;
• and
• automatically positioning at least the another one of said pair of external side rearview mirrors and said interior rearview mirror based on the instantaneous position and to readjust a position of at least one of said pair of external side rearview mirrors and said interior rearview mirror based on said detected external side rearview mirror setting method and a position of said driver seat of the vehicle.

A method of operating a rear vision system for a vehicle, said method comprising the steps of:

• receiving a power mirror user input;
• determining a driver task selected based on the power mirror user input;
• repositioning a left-hand side rearview mirror if the driver task selected is a left-hand side rearview mirror;
• recording a left-right angle and up-down angle of the left-hand side rearview mirror;
• determining whether the left-right angle of the left-hand side rearview mirror is greater than a predetermined threshold;
• calculating a driver eyes location and left-right angle and up-down angle of a right-hand side rearview mirror and an interior rearview mirror using a Blindzone/Glare Elimination setting formula if the left-right angle of the left-hand side rearview mirror is not greater than a predetermined threshold;
• calculating a driver eyes location and left-right angle and up-down angle of a right-hand side mirror and an interior rearview mirror using a Blindzone setting formula if the left-right angle of the left-hand side rearview mirror is greater than a predetermined threshold;
• repositioning the interior rearview mirror;
• repositioning the right-hand side rearview mirror;
• determining whether errors of the left-right angle and the up-down angle of the interior rearview mirror are less than a predetermined value or time expired;
• determining whether errors of the left-right angle and the up-down angle of the right-hand side rearview mirror are less than a predetermined value or time expired;
• repositioning the interior rearview mirror if the errors of the left-right angle and the up-down angle of the interior rearview mirror are not less than a predetermined value or time expired;
• and
• repositioning the right-hand side rearview mirror if the errors of the left-right angle and the up-down angle of the interior rearview mirror are not less than a predetermined value or time expired.
