The present disclosure relates to a vehicle steering wheel, including: a steering wheel body with a hub region for attachment to a steering shaft, with a steering wheel rim and with at least one spoke for attaching the steering wheel rim to the hub region; an airbag initiation device; wherein an electromechanical triggering device has at least one force transducer, which is disposed between a projection and the steering wheel body and via which the impact absorber cover is supported on the steering wheel body, for measuring a force value that can be associated with an actuating force acting on the actuating surface of the impact absorber cover; wherein the electromechanical triggering device has at least one electronic evaluation unit connected in an electrically conductive manner to the force transducer to determine an actuating force value by a force value measured by the at least one force transducer.

A vehicle steering wheel system is provided. The system includes a steering wheel body with a hub region for attachment to a steering shaft of a vehicle steering system, a steering wheel rim and at least one spoke for attaching the steering wheel rim to the hub region; an electromechanical triggering device for triggering an acoustic output by means of an acoustic warning device of the vehicle, wherein the triggering device has an impact absorber cover and at least one force transducer wherein a force value threshold is predefined for each force transducer, and a wake-up signal is transmitted via the data connection to the evaluation unit if the force value threshold is exceeded by at least one force value, so that the latter changes from the energy-saving mode into the operating mode in which an actuating force value is determined by force value measured by the at least one force transducer.

A multifunction operating device includes a carrier; an input part which has an input surface comprising an array of operating surfaces and which is to be mounted so as to be able to move relatively to the carrier; a touch sensor system which is designed to detect a touching of the input surface by an operating member of an operator, which touching is spatially resolved on the different operating surfaces, and to provide it as a touch detection result; a control unit electrically connected to the touch sensor system; an actuator electrically connected to the control unit and having an effective direction (W) for driving the input part so as to move it relatively to the carrier in order to generate an active haptic; the control unit is designed to trigger the active haptic depending on the touch detection result; an electromechanical switching element electrically connected to the control unit and arranged between the input part and the carrier in order to detect an actuation exerting a minimum actuating force on one of the operating surfaces by means of a switching operation of the electromechanical switching element and to optionally generate an associated mechanical switch haptic.
