Abstract:
1. A method for determining a vehicle speed of a motor vehicle through a control device, comprising the steps of: determining a provisional first speed value for high speeds and a provisional second speed value for low speeds, the provisional first speed value being determined such that that it assumes the value zero if no clear driving direction of the vehicle is detected and/or if a standstill state is detected; and determining the vehicle speed as a function of the determined provisional first speed value either from the provisional first speed value or from the provisional second speed value or from a combination of the first and second speed values, wherein the provisional second speed value is determined such that it either corresponds to the average of all the actual wheel speeds if none of the determined actual wheel speeds is negative and otherwise is determined as a function of the total of the negative wheel speeds.
