An apparatus and method for retracting an awning. A sensor detects an awning acceleration caused by wind impacting the awning, and generates a signal having an amplitude corresponding thereto. When the signal exceeds a certain threshold, the awning is retracted. The signal's amplitude may be converted into a frequency, and the frequency compared to the threshold. The signal typically must exceed the threshold for a set period of time to trigger awning retraction. A second threshold may dictate a maximum instantaneous or peak acceleration; when the signal exceeds this second threshold, regardless of the duration during which the second threshold is exceeded, the awning is retracted.

Appareil et méthode pour rentrer un auvent. Un capteur détecte l'accélération de l'auvent causée par l'impact du vent sur l'auvent, et produit un signal correspondant à l'amplitude. Lorsque le signal dépasse une certaine limite, l'auvent est rentré. L'amplitude du signal peut être convertie en fréquence, et celle-ci est comparée à la limite. Le signal doit généralement dépasser la limite pendant une période de temps établie pour activer la rentrée de l'auvent. Une deuxième limite peut établir une accélération instantanée maximale ou une accélération de pointe et, lorsque le signal dépasse cette deuxième limite, peu importe la durée de dépassement, l'auvent est rentré.
