1. An operating unit for a utility vehicle, having a grip zone, at least one actuation unit and a control unit, wherein the grip zone includes a plurality of contact-detecting sensor units, wherein the control unit is designed to detect signals from the sensor units and to identify an intended operation on the basis of the signals, wherein an arrangement of the sensor units is formed in such manner that various hand positions are identifiable by the control unit, wherein the control unit is designed to enable a control signal generated by the operating unit and/or the at least one actuation unit in each case depending on the position of the hand, which a grouping of the sensor units of the grip zone are read out together, the grouping includes at least two adjacent sensor units, and an enablement of the control signal may be effected even if the number of contacts identified is lower than the number of sensor units of the grouping; and wherein when the sensor units identify that at least one finger of the hand is in a first hand position and that at least one finger of the hand covers a first actuation zone including a first one of the at least one actuation unit, then the control signal from the first actuation unit is not enabled; and when the sensor units identify that at least one finger of the hand is in the first hand position and that at least one finger of the hand covers a second actuation zone spaced from the first actuation zone and including a second one of the at least one actuation unit, then the control signal from the second actuation unit is enabled.
