Control of an internal combustion engine in a vehicle

A computer program product comprising computer program code stored on a non-transitory computer-readable medium readable by a computer, said computer program product used for control of a combustion engine during a road section, in a vehicle comprising one or several engines, wherein said vehicle is coasting with said combustion engine shut down, said computer program code comprising computer instructions to cause one or more computer processors to perform the operations of:

• simulation of at least one future speed profile Vsim_ICE_off for an actual speed vact of said vehicle during said road section, wherein said simulation is carried out when said road section is ahead of said vehicle, and wherein said simulation of each one of said at least one future speed profile Vsim_ICE_off is based on information about said road section and on knowledge that said coasting with the combustion engine shut down will, at least initially, be applied during said road section;
• determination of a starting point in time tICE_start, when a forward driving force from said combustion engine in said vehicle will be required again, and/or because one or several braking systems in said vehicle will need to be activated, wherein said determination of said starting point in time tICE_start is based on said at least one starting point brought forward in time, tICE_pre_start;
• determination of a starting point brought forward in time, tICE_pre_start, which precedes said starting point in time tICE_start by an advancing period TICE_pre_start;
• and
• starting said combustion engine at said starting point brought forward in time tICE_pre_start.

A system arranged for control of a combustion engine during a road section, in a vehicle comprising one or several engines, whereat said vehicle is coasting with said combustion engine shut down, wherein said system comprises:

• a simulation unit, arranged for simulation of at least one future speed profile Vsim_ICE_off for an actual speed vact of said vehicle during said road section, whereat said simulation is carried out when said road section is ahead of said vehicle, and wherein said simulation of each one of said at least one future speed profile vsim_ICE_off is based on information about said road section, and on knowledge that said coasting with the combustion engine shut down will, at least initially, be applied during said road section;
• a first determination unit, arranged for determination of a starting point in time tICE_start, when a forward driving force on said vehicle will be required again from said combustion engine and/or because one or several braking systems in said vehicle will need to be activated, wherein said determination of said starting point in time tICE_start is based on said at least one starting point brought forward in time tICE_pre_start;
• a second determination unit, arranged for determination of a starting point brought forward in time, tICE_pre_start, which precedes said starting point in time tICE_start by an advancing period TICE_pre_start;
• and
• a starting unit, arranged for start of said combustion engine at said starting point brought forward in time, tICE_pre_start.
