Abstract:
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.
