Abstract

A system for level regulation of a driver's cab of a commercial vehicle relative to a chassis of the vehicle includes a spring-loaded bearing in order to support the driver's cab in a sprung manner on the chassis of the vehicle; a distance sensor device arranged to record relative movements and/or a distance between the driver's cab and the chassis of the vehicle; and a control device that is arranged for variable control of the spring-loaded bearing, wherein signals of the distance sensor device are used to control the spring-loaded bearing. The spring-loaded bearing can be adjusted to a first height position (h1), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control device to a first target distance. The spring-loaded bearing can be adjusted to at least one second height position (h2), so that the distance between the driver's cab and the chassis of the vehicle is controlled by the control means to a second target distance. The control means device adjusts the spring-loaded bearing to the first height position (h1) or to the at least one second height position (h2) depending at least on a parameter relating to a driving route a…
