Abstract

The invention is directed to an arrangement for detecting the position of an accelerator pedal and/or a power-determining element of an internal combustion engine of a motor vehicle. The arrangement has at least two measuring devices as well as monitoring means which check the function of these measuring devices on the basis of the measuring signals thereof. In addition, a further measuring device in the form of a switch element is provided which likewise generates a signal representative of the position of an accelerator pedal and/or power-determining element of an internal combustion engine of a motor vehicle. A microcomputer selects on the basis of all three measuring signals at least one of the measuring signals for controlling the drive power of the engine in a motor vehicle. The switching element is a Hall switch.
