1. A pedal system for a vehicle comprising:
a processor;
a driving pedal; and
a brake pedal,
wherein the pedal system is allocated a representation function between a pedal actuation and control parameters for the longitudinal control of the vehicle, the pedal system is configured so as, when the vehicle is being operated, to vary the representation function between the pedal actuation and the control parameters for the longitudinal control of the vehicle in dependence upon a variable that represents the degree of automation of the driving mode of the vehicle and at least a first condition for restricting the representation function of the pedal actuation and at least a second condition for eliminating the restriction of the representation function of the pedal actuation,
the representation function is a representation of a pressure force on, or a position of, the driving pedal or the brake pedal,
the variable representing the degree of automation may assume a first value and a second value representing a higher degree of automation than the first value, and the driving modes include at least two different driving modes of the following driving modes: a manual driving mode, an assisted driving mode, a part-automated driving mode, a highly automated driving mode, an automated driving mode, and an unknown driving mode,
wherein the processor is configured to:
ascertain one or more parameters of a driving situation;
ascertain the measure of the restriction of the representation function for the pedal system in dependence upon the one or more parameters that are ascertained for the driving situation; and
vary the representation function between the pedal actuation and the longitudinal control of the vehicle for the pedal system in dependence upon the ascertained measure of the restriction,
wherein the measure of restriction is dependent upon a necessity that is established using other means of the vehicle and a potential danger and a recommendation for action to perform a specific maneuver.
