ABSTRACT:
A method for simulating an impression which is perceived subjectively by an occupant of a vehicle, in particular of a passenger car, when the vehicle is being operated, as well as a device, for example, for carrying out such a method are provided. In the method, the primary oscillations which are produced when a vehicle to be investigated is being operated and which are perceived subjectively are registered. Data for generating secondary oscillations are acquired from the primary oscillations and are converted into the secondary oscillations, and a simulation unit, which simulates, among other things, in particular a passenger car representationally at least in certain areas, is operated. In the simulation unit which is elastically mounted or secured with respect to the floor, vibration oscillations, which are acquired from the primary oscillations, are induced at a location from which they are transmitted into a seat and/or into the steering wheel. In order to determine the source of the complaints, specific frequencies of the vibration oscillations are then changed selectively.
