NEW APPROACH TO MEASURE THE VEHICLE CENTRE OF GRAVITY HEIGHT

The vertical position of the car’s centre of gravity is one of the main parametersthat influence vehicle handling and thus also the active traffic safety. The vehiclehandling is nowadays frequently researched with the help of mathematicalsimulations, but for these it is necessary to provide correct values of the individualparameters of the vehicle. This study presents new approach to the measurement ofthe centre of gravity height with the help of a device which is primarily designatedto measure the vehicle’s moments of inertia. This method utilizes the influence of thecentre of gravity height on the value of the measured oscillation period of thedesigned device. The method is verified, first on the known parameters and then onthe two vehicles
