An electric circuit for controlling the access and immobilizing a vehicle has a first antenna driver () for driving a first antenna () for emitting a signal () in the event of identification of an ID transmitter () for access control of a vehicle. A second antenna driver () is provided for driving a second antenna () for emitting a signal () in the event of identification of an ID transmitter () for the immobilizer of the vehicle. In addition, the electric circuit has a receiver device () for receiving a signal captured by an antenna () for the identification of an ID transmitter () for the immobilizer. The first antenna driver () and the receiver device () are commonly integrated into a semiconductor chip ().

Electric circuit for an access control and for an immobilizer of a vehicle and method for calibrating an antenna driver

The invention relates to a rotary/push-button controller having a controller ring () which can be rotated about a rotation axis () and is arranged such that it can rotate on a holding cylinder () which is arranged coaxially within the control ring (). In this case, the holding cylinder () is provided at its end with an input and/or display field (), and the control ring () and the holding cylinder () can be moved axially with respect to the rotation axis () against a spring force from a neutral position to a switch position which operates a switching element. The input and/or display field () is mounted so that it can rotate about the rotation axis (). A rotary transmitter ring is arranged coaxially on the control ring () and is arranged coaxially alongside a rotary transmitter () which is firmly connected to the holding cylinder () with the relative rotation position of the rotary transmitter ring with the respect to the rotary transmitter () being recordable.

Rotary/push-button controller

The invention relates to a rotating actuator/pressure actuator () comprising a ring-shaped rotary transducer () consisting of an inner ring and a rotary ring with a handle () and which can rotate around the inner ring about an axis (z) and which is displaceably arranged in a linear manner along the axis (Z) in relation to a housing (), in addition to an inner part (touchpad) which is arranged in an inner area () of the ring-shaped rotary transducer () and which is displaceable in a linear manner along the axis (z) together with the ring-shaped rotary transducer () in relation to the housing (). Linear displacement of the handle () and/or inner part (touchpad) triggers a push-button function. According to the invention, the rotary transducer () and inner part (touchpad) are arranged in a pan-shaped guide element () which is arranged in a linear displaceable manner along the axis (z) in the housing; the inner ring of the rotary transducer () is rotationally fixed in the guide element (); the rotary transducer () and the inner par (touchpad) are connected to the guide element () in such a way that they are not displaceable along the axis (z) and the guide element () acts upon the push button ().
