Method and a system for controlling a vehicle comprising an engine exhaust system

A computer-implemented method for controlling a vehicle comprising a combustion engine, drive members, and an engine exhaust system comprising a particulate filter, the method comprising: determining that a first condition is fulfilled, such as when a downhill condition applies, determining if a second condition is fulfilled, wherein the second condition is considered fulfilled if an amount of soot in the particulate filter exceeds a threshold amount, and/or if a temperature at the particulate filter exceeds a temperature threshold level, in response to determining that the first condition is fulfilled, and the second condition is not fulfilled, controlling the vehicle to turn off the combustion engine, in response to determining that the first and second conditions are fulfilled, controlling the vehicle to supply fuel to the combustion engine, the engine being drivingly disconnected from the drive members.
