Asymmetric, noise-optimised wiper trajectories, tool for their development, and method for operating a wiper drive with an asymmetric, noise optimised wiper trajectory

摘要

The method involves defining a predetermined trajectory, where the desired trajectory covers the asymmetry generated by a time-axis transformation function or a frequency modulation function. The desired trajectory has a tangential continuity, particularly curvature continuity. A wiper system is operated by a motor, which is driven to follow the desired trajectory. Independent claims are included for the following: (1) a method for determining a desired trajectory for a wiper system with a motor for a windscreen wiper; (2) a control device for a wiper system; (3) a computer program product with program code; and (4) a desired trajectory authoring tool.
