A control unit for a level control device of a mechanically and/or pneumatically/hydraulically suspended vehicle includes a control device configured to control the level and a sensor device installed in the vehicle and/or are functionally expanded such that in addition to the level control or in lieu of the level control, functions can be added for ascertaining the load on mechanically suspended axles and on pneumatically/hydraulically suspended axles. An interface is configured to receive signals from sensors suitable at least for ascertaining the load on mechanically suspended axles. The control unit has a first storage for sensor-specific characteristic curves and a second storage for an algorithm for processing or reprocessing the signals forwarded or processed using the interface. For each stored sensor type, the current load on the mechanically suspended axle in question can be ascertained by correlating the signal with the characteristic curve for the sensor type.

A snowmobile including a right front suspension assembly and a left front suspension assembly, each of the left and right front suspension assembly including: a ski leg; an upper A-arm and a lower A-arm, the upper and lower A-arms being connected between the ski leg and the chassis; and a shock absorber connected between one of the upper and lower A-arms and the chassis; a first sensor connected between one of the upper and lower A-arms of the right front suspension assembly and the chassis to measure the angle therebetween; a second sensor connected between one of the upper and lower A-arms of the left front suspension assembly and the chassis to measure the angle therebetween; and a controller communicatively connected to the first sensor and the second sensor, the electronic signals representing angular position between the A-arms of the right and left front suspension assembly and the chassis.
