Abstract

A transmission device may be provided for transmitting an angle of activation of a selector lever for a vehicle transmission, where the selector lever can assume a plurality of angles of activation. The transmission device may include a transmission lever, where the transmission lever may be rotatable about a first axis and may be configured to receive the angle of activation of the selector lever. The transmission device may further include a signal lever, where the signal lever may be rotatable about a second axis and may be configured to provide a transducer angle to a transmitter element of a sensor. A drive device may be included. The drive device may couple the transmission lever with the signal lever and may be configured to transmit the angle of activation received by the transmission lever to the transducer angle provided by the signal lever.
