Abstract
A method and a system for estimating a road gradient α by using a sensor fusion: Detect whether at least one dynamic process is affecting the vehicle. Estimate gradient α by means of the sensor fusion by joint weighting of at least two input signals to the sensor fusion. The at least two input signals include a signal based on an accelerometer and an input signal based on at least one force equation. At least one of the input signals and/or at least one weighting parameter for the sensor fusion are determined on the basis of detecting whether the at least one dynamic process is affecting the vehicle.
