In this case, distance signals of the sensor modules in the rear and front area can be displayed by tones with different frequency to the driver. By deactivating the reverse gear, a sensor module in the front area can be activated by the display module. If the sensor module in the front area then sends no distance signals to the display module, this is deactivated. This makes it possible for the parking aid to automatically detect whether a sensor module is present in the front area or not. In the event of subsequent installation of a sensor module in the front area, nothing needs to be entered further into the other components of the parking aid or modified on them.

Abstract

L'invention concerne une assistance électronique au stationnement pour véhicules à moteur, qui comporte un module d'affichage (45) en tant que premier composant principal, pourvu d'un premier composant de communication sans fil pour la transmission sans fil de données entre un module capteur (43) et le module d'affichage (45), un module capteur (43) en tant que deuxième composant principal, pourvu de capteurs de distance (25) et d'un capteur solaire (1) sous la forme d'un module photovoltaïque associé à un accumulateur tampon. L'énergie convertie peut être produite par des vibrations ou des accélérations du véhicule ou des différents composants de l'assistance au stationnement, par exemple à l'aide d'au moins un élément piézoélectrique, d'au moins un noyau magnétique se déplaçant dans une bobine ou d'au moins une bille, un rouleau ou un autre élément magnétique qui roule dans au moins une bobine et induit ainsi une tension.
