Method and device for dynamically determining a slope of a road

摘要

For dynamically determining a slope (TETA) of a road a total acceleration (ACC_TOT) which affects a vehicle on the road in longitudinal direction of the vehicle is measured. A first component (ACC_VEH) of the total acceleration (ACC_TOT) of the vehicle which is caused by a change of a speed of the vehicle is determinded. A second component (ACC_GRAV) of the total acceleration (ACC_TOT) of the vehicle which is caused by the gravity affecting the vehicle in longitudinal direction of the vehicle is determined dependent on the total acceleration (ACC_TOT) and dependent on the first component (ACC_VEH) of the total acceleration (ACC TOT). The slope (TETA) of the road is determined dependent on the second component (ACC_GRAV) of the total acceleration (ACC_TOT).
