Abstract
Process for determination of the position of a door, window or roof of an automobile vehicle, according to which the angular position of the rotor of the electric motor actuating this door, window or roof is determined and the position of the door, window or roof is calculated as a function of the said angular position. The position of the door, window or roof is calculated by correcting a theoretical position that depends on the angular position by a term that takes account of the stiffness of the mechanical transmission between the door, window or roof and the electric motor, this term being a function of the motor power supply current. The device embodying this process is advantageously used in an electric window winder.
Claims8
Process for determining the position of at least one of a vehicle door, window and roof, according to the following steps:
- determining the angular position of the rotor of the electric motor actuating said window, roof and door,
- calculating a theoretical angular position of at least one of a window, roof and door as a function of said angular position, and
- correcting the theoretical angular position of the door, window and roof by a term taking account of and being a function of an elasticity and stiffness of a drive system including transmission elements extending between the door, window and roof and the electric motor.
