A method for operating a control unit for heat-sensitive actuators includes first disabling the control unit after a thermal loading, which is calculated on the basis of the computing model, of at least one actuator has reached a threshold.

Method for operating a control unit for heat-sensitive actuators

A method for controlling or regulating a level control system for a motor vehicle including a compressed air source, at least one air spring, a switchable directional control valve associated with the air spring and a master line connecting the compressed air source to the switchable directional control valve. The switchable directional control valve blocking the master line in a normal state thereof and connecting the master line through for filling the air spring in a switching state thereof. The master line is filled with compressed air before filling the air spring until the air pressure in the master line is at least equally as high as a predetermined threshold value, and only thereafter is the switchable directional control valve transferred into the switching state for filling the air spring. A level control system for a motor vehicle is also provided.

Level control system and method for controlling or regulating a level control system

The invention is directed to a level control system for a motor vehicle wherein the controllable valves (,to,and,) are controlled by a first control unit (,). The first control unit (,) transmits a signal to a second control unit (,) at time intervals. If the second control unit (,) does not receive the signal expected from the first control unit, then the second control unit (,) assumes the control of the valves (,to,and,) in such a manner that the motor vehicle is transferred into a dynamically safe driving condition.
