Method for controlling an operating device for a motor vehicle and operating device

ActiveCN109835193BInput/output for user-computer interactionElectrical haptic/tactile feedbackMechanical engineeringPhysics
The invention relates to a method for controlling an operating device (1) for a motor vehicle, which operating device (1) has an operating element (11). In this method, a spring-elastic element (16) arranged below the operating element (11) is moved and / or deformed indirectly or directly by a piezoelectric element (14). At least one haptic feedback is provided to the operator when operating the operating element (11). The invention proposes that, when controlling the piezoelectric element (14), the spring-elastic element (16) is moved in the direction of the operating element (11) and comes into contact with the operating element (11). As a result, when operating the operating element (11), the spring-elastic element (16) is transformed from a stable starting position into an unstable deformed position. When the operating element (11) is released, the spring-elastic element (16) spontaneously returns from the deformed position to the starting position. In the transformation from the starting position to the deformed position and vice versa, a haptic feedback is generated by the spring-elastic element (16) respectively. By means of these features, a haptic feedback can be generated in a simple and low-cost manner when operating the operating device.
