Method and apparatus for controlling a power window system using a motor torque parameter

A program of instructions storable on a computer readable medium for causing a computer to implement steps for operating a power window system, the steps comprising:

• operating a motor for a predetermined amount of angular rotation of a rotor of the motor under a predetermined set of operating conditions;
• measuring the amount of time of angular rotation of the rotor;
• determining a torque parameter based on said operating and said measuring steps;
• compiling a table of operating values for the motor based on said operating, said measuring, and said determining steps;
• and
• operating the motor based upon the table of operating values.

An apparatus, comprising:

• means, coupleable to a window, for moving the window disposed in a vehicle and capable of being disposed in at least two positions from a first one of the at least two positions to a second one of the at least two positions;
• and
• means for controlling said moving means, said controlling means being capable of determining a position of said moving means with respect to the window using a parameter of said moving means,
• the parameter of said moving means including a torque parameter value.

A vehicle, comprising:

• a window disposed in the vehicle and capable of being disposed in at least two positions;
• means, coupleable to said window, for moving the window from a first one of the at least two positions to a second one of the at least two positions;
• means for controlling said moving means, said controlling means being capable of determining a position of said moving means with respect to the window using a parameter of said moving means;
• and
• an engine disposed in said vehicle, said engine being capable of providing propelling said vehicle and being capable of providing power to said moving means,
• the parameter of said moving means including a torque parameter value.
