Problems solved by technology

However, standardization of travel is not possible in some systems, and thus accurate determination of position during and after movement is also not possible

Embodiment Construction

[0028] figure 1 The individual sequences of a method for determining the position of an adjusting element, in which a position change or inaccuracies occurring of the adjusting element can be detected even after switching off, are shown diagrammatically. The method can, for example, be divided into three separate processes, which are carried out once, repeatedly or continuously, sequentially or simultaneously:

[0029] a) One of the processes (MP) involves measuring or determining physical parameters associated with regulating the system. Some physical variables relate here to the movement of the adjusting element itself and thus to the initial position of the adjusting element, such as the rotational speed of the electric motor in the drive unit or the speed of the adjusting element or the distance traveled by the adjusting element. Others relate to system parameters and environmental parameters, such as the temperature of the drive unit, the electrical parameters of the dri...

Abstract

A method and a system for determining the position of an adjustment system having an immovable element, an adjustment element which can move relative to the immovable element and a drive unit for the adjustment element are presented. The invention provides for physical variables (MP) to be determined in connection with the adjustment system, for a learning process (LP) to be carried out in order to determine and learn position deviations or position changes of the adjustment element at an operating point of the electrical adjustment system (LP) determined by the physical variables, and for the actual position of the adjustment element to be determined by taking into account the determined physical variables and the learnt position deviations or position changes of the adjustment element for the particular operating point.

Description

technical field [0001] The invention relates to a method and a system for position determination in an adjustment system, in particular to a method and a system for position determination in an electrical adjustment system of a vehicle. Background technique [0002] The adjusting system has an immovable (stationary) element and a movable adjusting element, the position of which can be adjusted, ie changed, relative to the immovable element by means of the drive unit. In the field of motor vehicle technology, adjustment systems are used, for example, to adjust sliding roofs, doors, rear lids, load floor adjustments, seats or window panes. The position determination in the adjustment system is usually determined indirectly, for example via the speed of the movable adjustment element, the adjustment distance covered or the rotational speed of the drive system. Under certain conditions, however, the adjusting element can be moved unintendedly, for example in the opposite direct...
