  • the sensitive areas are those areas that can not yet be cleaned by machine, since a cleaning with the usual parameters would cause damage to the surface.
  • adjustments of the cleaning parameters can also be made manually by a driver. However, this requires a great deal of attention and experience of the driver, who at the same time must take into account the control of locomotion.
  • Document DE 20 2012 006 267 111 discloses an autonomous mobile multipurpose device, which, according to one embodiment, can also be a cleaning machine [0002] whose area or spatial position can be determined by means of GPS data. Such GPS data can also be stored in order to take into account obstacles on a driving route.

  • Logging capabilities on the vehicle's on-board system can automatically create log books with evidence of current brush speed, contact pressure and suction, vehicle speed, etc. This can be used as a proof of performance for the driver, as well as for the proof of the city cleaning operation that has been cleaned according to schedule and agreed.
  • a dirt detection with independent training algorithm is particularly advantageous.
  • the vehicle recognizes the type of soiling (e.g., leaves or beverage cans), then the degree of soiling is determined (e.g., light, medium or heavy). From this information, the suction power is controlled as well as broom speed and sweeping profile (e.g., pulsating cleaning). The dirt is detected both in front of the vehicle and after the vehicle (after cleaning). If the contamination is insufficiently removed, the system stores this information and increases the performance the next time the same situation is identified (independent learning).
  • a further advantageous embodiment of the machine according to the invention comprises a hazard detection. It is known that the desired reduction of the background noise of vehicles also involves dangers. So there is an increased risk potential due to non-recognition of the vehicle. It is assumed that especially in areas in which the cleaning vehicles are used primarily (for example, in pedestrian areas) there is an increased accident potential, because passers-by do not expect vehicles here.

  • the endangered passer-by is first pointed out by targeted flashes of light on a possible hazard. If the danger becomes acute, additional warning signals (warning sounds) are emitted to the outside. In the last stage, the vehicle can stop automatically or also switch off the ancillaries.
  • the built-in sensor for dirt detection can be used multiple times via the additional hazard detection.
  • Another advantage is the possibility of autonomous or semi-autonomous driving. By implementing environment sensors is an autonomous or teilautautonomes Driving possible. The system automatically detects the optimal approach path and brush position. This means that complicated, twisted surfaces can be cleaned optimally and as quickly as possible, which is often only possible thanks to many years of professional experience. This can save both energy and time.
  • a dust protection device with atomizing nozzles has also proved to be advantageous. Since the driver no longer has to actively observe the brushes, a dust protection device can be attached to the vehicle. In addition, atomizer nozzles, which counteract the raising of dust, can be integrated into this housing. Thus, particulate matter caused by the broom revolutions can be reduced. Another advantage is that this cover is again noise-dampening.
