  • the actuator unit 5 under control of the control unit 3 moves the device 4 and the cover 8 of the protecting assembly 1.
  • the bi-directional arrow between the protecting assembly 1 and the control unit 3 illustrates the control and/or data connection for control of the device 4 by the control unit 3 and for supplying operational data produced by the device 4 to the control unit 3 for further processing, e.g. in an autonomous driving mode of the vehicle 2.
  • Figures 7a and 7b illustrate flow diagrams of two embodiments of a protecting method for protecting a device of a vehicle, preferably by means of the protecting assembly 1 discussed above in connection with the Figures 1-6 and the device 4 and cover 8.
  • both embodiments of the method of protecting the device 4 comprise a step SO and a step SI.
  • step SO the device 4 is assumed to be in a first position A, in which the device 4 is exposed to the outside of the vehicle 2, e.g. by projecting from the skin 7 of the vehicle 2 at the location of the aperture 6.
  • the first position A is an operating position of the device 4.

  • step S20 the cover 8 is moved over the aperture 6 to cover and protect and hide the device 4 behind the cover 8.
  • step S02 the cover 8 is moved away from the aperture 6 so that the aperture 6 and thus the device 8 are no longer covered by the cover 8 so that the device 4 can be moved though the aperture 6.
  • step S10 is performed first and then step S20 is performed.
  • step S20 is performed first and then step S20 is performed.
  • steps S02 and SOI are performed consecutively, as well, i.e. step S02 is performed first and then step SOI is performed.
  • steps S10 and S20 are performed in parallel.
  • steps S02 and SOI are performed in parallel, as well.
  • the device 4 in the steps S10 and SOI, is moved between the first position A and the second position B, and vice versa, in a translational and/or rotational movement, respectively.
  • the cover 8 in the steps S20, is moved from the position in which it is fitted into the aperture 6 with a first moving step S20a with moving the cover 8 substantially into a direction towards the internal of the vehicle 2 and at least one second moving step S20b with moving the cover 8 in a translational and/or rotational movement away from the aperture 6 so that the device 4 can be moved through the aperture 6.
  • the steps S02a and S02b are respective reversed versions of the steps S20a and S20b.
