Abstract
A method of controlling an internal combustion engine in a vehicle that includes a cylinder, a fuel system for supplying fuel to the cylinder, an air guide arranged to guide an air flow to the cylinder, and an exhaust guide arranged to guide a gas flow from the cylinder, the method including controlling the engine to provide a braking torque, the control including terminating the supply of fuel to the cylinder, restricting the flow through the exhaust guide, and restricting the flow through the air guide. The control of the engine to provide a braking torque also includes determining a value of a rotational speed of a turbocharger of the engine, and adjusting, in dependence on the determined turbocharger rotational speed value, the restriction of the flow through the air guide, and/or the restriction of the flow through the exhaust guide.
