UNIT FOR CONTROLLING A SELF-PROPELLED VEHICLE FOR MAINTENANCE OPERATIONS OF A GROUND OR A FLOOR AND ASSOCIATED CONTROLLING METHOD

The present invention relates to a control unit (300) for controlling a self-propelled vehicle (10), electrically connectable with at least one wire (201) delimiting a ground or floor (100) on which the self-propelled vehicle (10), when in use, carries out maintenance. The control unit (300) comprises at least one output (301) configured to be connected to the wire (201) and on which, when in use, a driving signal (30) is fed for the self-propelled vehicle (10), a power stage (302) connected to the output (301) and configured to feed the driving signal (30) on the output (301), and a resistance measurement stage (303), connected to the output (301), configured to measure an electrical resistance (R) of the wire (201) when connected to the output (301). According to the invention, the control unit (300) envisages an operational measurement configuration and an operational power supply configuration. In the operational measurement configuration, the control unit (300) varies, through the power stage (302), the voltage and/or the current of the driving signal (30) according to the electrical resistance (R) measured by the resistance measurement stage (303). In the operational power supply configuration, the control unit (300) performs, through the power stage (302), at least one generation step of a driving signal (30) for the self-propelled vehicle (10).
