Abstract
A method for determining vehicle characteristic variables of a motor vehicle. The motor vehicle has active dampers which can set adjusting forces at the respective wheel suspensions in order to be able to raise and/or lower the body of the motor vehicle and which can also measure the acting forces. Specific predefined adjusting forces of the active dampers are imparted in order to ascertain vehicle characteristic variables from the resulting adjustment and the resulting measured forces.
Claims12
A method for determining vehicle characteristic variables of a motor vehicle that has a plurality of active dampers configured to set adjusting forces at wheel suspensions in order to raise and/or lower a body of the motor vehicle, said method comprising:
- voluntarily activating the active dampers to impart specific predefined adjusting forces at the wheel suspensions while the motor vehicle is at a standstill;
- measuring acting forces at the wheel suspensions resulting from the specific predefined adjusting forces imparted by the activated active dampers;
- and
- ascertaining at least one vehicle characteristic variable among the vehicle characteristic variables as a function of the specific predefined adjusting forces and the measured acting forces,
- where the at least one vehicle characteristic variable is at least one of:
- center of gravity position in a vehicle longitudinal direction, center of gravity position in a vehicle transverse direction, or center of gravity position in a vehicle vertical direction.
