Abstract

An arrangement for transmitting data and/or signals between a transmission control device (1) and a plurality of actuator control devices (2A, 2B, 2C) for the local control of actuation movement of actuating shifting units. The transmission control device (1) and the actuator control devices (2A, 2B, 2C) are disposed such that they are movable relative to one another. At least one wireless communication transmission unit is provided, at least in sections, between the transmission control device (1) and the actuator control devices (2A, 2B, 2C).

Claims

1-5. -5. (canceled)

6. An arrangement for transmitting at least one of data and signals between a transmission control device (1) and a plurality of actuator control devices (2A, 2B, 2C) for local control of actuation movement for actuating shifting units, the transmission control device (1) and the actuator control devices (2A, 2B, 2C) being disposed such that the transmission control device (1) and the actuator control devices (2A, 2B, 2C) are movable relative to one another,

wherein at least one wireless communication transmission unit is provided between the transmission control device (1) and the actuator control devices (2A, 2B, 2C).

7. The arrangement according to claim 6, wherein the communication transmission unit comprises at least one communication interface (5), on the transmission control device side, and at least one communication interface (4, 4A, 4B, 4C), on the actuator control device side, which communicate wirelessly with one other via at least one of a capacitive, an inductive, an optical and a radio-based transmission path (3).

8. The arrangement according to claim 7, wherein the transmission control device (1), fastened to a housing, is connected to the communication interface (5), fastened to the housing, via at least one wired data bus (7).

9. The arrangement according to claim 6, wherein the communication interface (4) on the actuator control device side is connected, via a wired data bus (6), to a plurality of actuator control devices (2A, 2B, 2C).

10. The arrangement according to claim 6, wherein a plurality of communication interfaces (4A, 4B, 4C), on an actuator control device side, are provided which are each connected, via a wired data bus (6A, 6B, 6C), to an assigned actuator control device (2A, 2B, 2C).

11. A transmission control and feedback system for transmitting signals between a transmission control device (1) and at least one actuator control device (2A, 2B, 2C) for controlling actuation of shifting units (14) of a transmission (10), the control and feedback system comprising:

a fixed communication interface (5) being fixed to a housing (16) of the transmission (10) and connected, via a wired first data bus (7), to the transmission control device (1) for transmitting the signals therebetween;

at least one movable communication interface (4) being coupled to a transmission shaft (18) and communicating, via at least one second data bus (6), with the at least one actuator control device (2A, 2B, 2C) for transmitting the signals therebetween, and

the at least one actuator control device (2A, 2B, 2C) being coupled to the transmission shaft (18) and a respective actuating unit (12) which actuates one of the shifting units (14); and

at least one wireless transmission path (3) being formed between the fixed communication interface (5) and the at least one movable communication interface (4) for transmitting the signals therebetween.

12. The arrangement according to claim 11, wherein the at least one wireless transmission path (3) is at least one of a capacitive, an inductive, an optical and a radio-based transmission path.
