Abstract:
1. A device for driving an actuator, comprising a power storage device for supplying the actuator, an antenna device, by means of which power for charging the power storage device and one or more control signals, which comprise a triggering command for triggering the actuator, can be received from a transmission device via a contactless communication, and a control unit for controlling the power supply from the power storage device to the actuator depending on the control signals, wherein the device is configured such that the charge state of the power storage device is determined after receiving the triggering command, wherein, in the case of a charge state of the power storage device lower than a charge state threshold value sufficient for triggering the actuator, a response signal for continuing the contactless communication is transmitted via the antenna device for reception by the transmission device, wherein, in the case of a charge state of the power storage device higher than or equal to the charge state threshold value, the control device controls the power supply from the power storage device to the actuator such that a triggering of the actuator is enabled, and wherein the transmitted triggering command is suitably processed without an error message, which is due to the power storage device that is not sufficiently charged, being returned.
