Patent number: 11976603Abstract: A method performed by a control unit in connection with a pre-heating process of an aftertreatment system for a combustion engine is provided. The control unit obtains a scheduled start time of the combustion engine. The control unit schedules a pre-heating of the aftertreatment system to be completed before the scheduled start time. The control unit detects a start of the combustion engine at an actual start time. In response to the detected start of the combustion engine, and using the actual and scheduled start times, the control unit determines whether the scheduled pre-heating of the aftertreatment system fulfils one or more success criteria. When the one or more success criteria are fulfilled, the control unit triggers a performance increase of the combustion engine.Type: GrantFiled: January 19, 2023Date of Patent: May 7, 2024Assignee: VOLVO TRUCK CORPORATIONInventors: Martin Wilhelmsson, Dan Stenqvist, Irman Svraka
