A method for setting operating states of an internal combustion engine, in particular an internal combustion engine of a hybrid drive. In addition to the internal combustion engine, the hybrid drive includes at least one electric drive, a hybrid coordinator and a control unit assigned to the internal combustion engine in which functions are implemented. The functions request operating states favorable to their running ability from the hybrid coordinator which performs a commensurate modification of the distribution of power between the internal combustion engine and the at least one electric drive.

A method of initializing a system for open/closed-loop control of the operating sequences of a motor vehicle is described. The system has a controller which is connected to a number of sensors via a data bus. The sensors have suitable means which allow a response to be transmitted staggered in time. In order to initialize the system, the controller first transmits a transmission request to sensors of the same type. The sensors of the same type transmit responses staggered in time back to the controller. During the transmission of the responses, a data field of each response is overwritten by the controller with a sensor-specific identifier and a corresponding transmission priority.

Method of initializing a system for open/closed-loop control of the operational sequences of a motor vehicle and a system for carrying out the method

A method for operating a clutch ( ), whose clutch slip (s) is adjusted to a setpoint value (s ) with the aid of a manipulated variable, should allow a clutch to be controlled in a particularly reliable and stable manner. To this end, the present invention provides for a slip value only being permitted to be a setpoint value (s ), when the derivative of the friction coefficient/slip characteristic at this slip value exceeds a specifiable limiting value. In particular, the setpoint value (s ) is selected as a function of a number of operating parameters, inside a range of permissible setpoint values (s ); the slip value, at which the derivative of the friction coefficient/slip characteristic falls below a specifiable limiting value, being selected as an upper limit (G) of the range of permissible setpoint values (s ).

Emergency hydraulic control for adjusting a constant clamping force ratio with regard to a continuously variable transmission

A hydraulic emergency control ( ) for a hydraulically actuated clutch ( ) arranged between an internal combustion engine ( ) is proposed. A pump ( ) driven by the internal combustion engine ( ) feeds a work line ( ) in which a choke ( ) is arranged. A regulating valve ( ) is provided for controlling the clutch ( ) at least in the event of failure of the electric supply. A first control line ( ) is connected by a first control input (S ) of the regulating valve ( ) with the work line ( ) in front of the choke ( ) with respect to the feed direction. A second control line ( ) is connected by a second control input (S ) of the regulating valve ( ) with the work line ( ) behind the choke ( ) with respect to the feed direction. Through the use of a regulating valve ( ), a variable control of the clutch ( ) is possible also in emergency operation. In all, very few structural component parts are required for this purpose.
