Abstract
A method for identifying a measured value of a velocity or speed of an object where a measured value call-in can occur at any time. A chronological spacing of measuring pulses of a speed sensor is measured and a measured value is formed therefrom. The measurement is carried out until either a measured value call-in occurs, a maximum number of measuring pulses is registered, or a maximum measuring duration is exceeded. When no measuring pulse or only one measuring pulse is registered, a distinction is made in the formation of the measured value as to whether a measuring duration corresponding to a minimum velocity or minimum speed is upwardly or downwardly crossed. An initial counter reading is stored at every measuring start and at every first registered measured pulse. A final counter reading is stored at every further registered measuring pulse until either a measured value call-in occurs or the maximum measuring duration is exceeded. The time interval lying between the initial counter reading and the final counter reading forms the basis for the calculation of the measured value.
