System for contactless transfer of energy and data and vehicle with such a system

A system for the contactless transfer of energy and data comprises a transfer path with a primary coil (8) and with a secondary coil (10). The primary control unit (4) is designed to lead data-modulated first alternating-voltage signals of a first frequency range into the primary coil (8). The secondary control unit (16) is designed to receive the first alternating-voltage signals of the first frequency range from the secondary coil (10), and to demodulate the modulated-on data. The system further comprises a feed-in line (7) for feeding a second alternating-voltage signal of a second frequency range to a primary line (6) leading to a primary coil (8) and an activation line (24) that is connected to a secondary line (14) that is connected to the secondary coil (10). A first filter (22) filters the second alternating-voltage signal from the secondary line and provides said signal to an activation connection (11). In this manner a signal may be transferred with great reliability by way of a transfer path of a contactless-operating system for the transfer of energy and data, wherein the primary control unit and the secondary control unit are bypassed.
