Claim 4:
5. The surface treatment vehicle of claim 1, wherein the speed and direction control signals output by the autonomy system are applied to the safety system, when being in the second mode of operation, and wherein the safety system is arranged to:
compare the speed and direction control signals with a maximum speed and a maximum direction given in the safety zone;
in case the speed and direction control signals conflict with the maximum speed and maximum direction given in the safety zone, to output limited speed and direction control signals to the controller which comply with the safety zone or to skip to output speed and direction control signals or to generate a safety stop signal; and
in case the speed and direction control signals do not conflict with the maximum speed and maximum direction given in the safety zone, output speed and direction control signals corresponding to speed and direction values in the received speed and direction control signals received by the autonomy system.
