Abstract

A method for adjusting an outside mirror of a vehicle includes providing at least one seat position sensor, a driver position detector and a mirror actuator. The position of the driver'"'"'s seat is determined with the at least one seat position sensor. An angular orientation of the outside mirror is adjusted with the mirror actuator based on the determined position of the driver'"'"'s seat such that a rear of the vehicle is visible in the outside mirror. Thereafter, a location of a driver'"'"'s head may be determined with the driver position detector when the driver is seated in the driver'"'"'s seat. The angular orientation of the outside mirror is readjusted with the mirror actuator based on the detected position of the driver'"'"'s head such that a rear of the vehicle is visible in the outside mirror when the driver is seated in the driver'"'"'s seat.

and

the position of the seat is determined by detecting the distance of the seat portion of the driver'"'"'s seat relative to a fixed point, detecting the angle between the seat portion and the seat back portion and determining a position of a head rest portion of the driver'"'"'s seat relative to the fixed point based on the detected distance and the detected angle.

9.

and

the position of the seat is determined by detecting the distance of the seat portion of the driver'"'"'s seat relative to a fixed point, detecting the angle between the seat portion and the seat back portion, detecting a height of the seat and determining a position of a head rest portion of the driver'"'"'s seat relative to a fixed point based on the detected distance, the detected angle and the detected height.

10. A method for adjusting an outside mirror of a vehicle comprising:

providing at least one seat position sensor, a driver position detector and a mirror actuator;

determining a position of the driver'"'"'s seat with the at least one seat position sensor;

adjusting an angular orientation of the outside mirror with the mirror actuator based on the determined position of the driver'"'"'s seat such that a rear of the vehicle is visible in at least a portion of the outside mirror;

detecting a location of a driver'"'"'s head with the driver position detector when the driver is seated in the driver'"'"'s seat;

readjusting the angular orientation of the outside mirror with the mirror actuator based on the detected position of the driver'"'"'s head such that a rear of the vehicle is visible to the driver in at least a portion of the outside mirror when the driver is seated in the driver'"'"'s seat;

rotating the mirror away from the vehicle when a turn signal of the vehicle is actuated; and

rotating the mirror toward the vehicle and downward when the vehicle is reversing.

11. The method of claim 10 wherein the driver'"'"'s position sensor comprises an optical system and the location of the driver'"'"'s head is determined by locating the eyes of the driver with the optical system.

12. The method of claim 10 further comprising adjusting a tilt of the outside mirror with the mirror actuator based on the determined position of the driver'"'"'s seat.
