Abstract:
The invention relates to a method for controlling a waste-heat utilization system ( 20 ) for a motor vehicle driven by an internal combustion engine ( 10 ) by means of a drive train ( 13 ), wherein the waste-heat utilization system ( 20 ) has at least one expander ( 22 ), at least one evaporator ( 21 ), and at least one pump ( 24 ) for an operating medium, in particular ethanol. At least the evaporator ( 21 ) is arranged in the region of the exhaust gas system ( 11 ) of the internal combustion engine ( 10 ). The expander ( 22 ), which can be operated in several operating modes, performs work in at least one operating mode. One operating mode of at least two operating modes ( 1, 2, 4, 5 ) of the expander ( 22 ) is selected by a control device ( 30 ) on the basis of at least one input variable from the group of expander rotational speed (n), gear information (GI), coasting information (CI), and pressure (p 1 , p 2 ) and temperature (T 1 , T 2 ) of the operating medium upstream or downstream of the expander ( 22 ) and the expander ( 22 ) is operated in said operating mode. A first operating mode ( 1 ) is associated with a warm-up phase of the expander ( 22 ) and a second operating mode ( 2 ) is associated with a normal operating phase of the expander ( 22 ). The bypass valve ( 26 ) is opened in the first operating mode ( 1 ) and closed in the second operating mode. The second operating mode ( 2 ) is selected if the pressure (p 2 ) and/or the temperature (T 2 ) of the operating medium downstream of the expander ( 22 ) exceeds a defined value.

Claim (Index 17):
The waste heat utilization system according to  claim 11 , wherein the expander can be operated in the selected operating mode by triggering at least one bypass valve of the expander disposed in a bypass flow path of the expander.
