Abstract

A method is provided for dynamically determining a tire longitudinal force. The method includes determining a tire acceleration variable by an acceleration sensor arranged in a tire bead, determining a first time interval between a tire contact patch entry point and an acceleration vertex by a processor unit, and determining a second time interval between the acceleration vertex and a tire contact patch exit point by the processor unit. The method also includes determining a magnitude or direction of a tire longitudinal force variable comprising a tire longitudinal force by the processor unit from a symmetry shift detected between the first and second time intervals.
