When there is a restart request to an engine, an electronic control unit controls a wastegate valve to a fully open position on condition that a speed of a vehicle is less than a threshold. When the vehicle speed is not less than the threshold, the electronic control unit restarts the engine and controls the wastegate valve in the closing direction until a desired torque is generated.

Controller and control method for forced induction device

An engine system includes a turbocharger (), an exhaust gas control apparatus (), a fuel addition device (), a heating unit, and an ECU. The turbocharger includes a variable nozzle mechanism (). The exhaust gas control apparatus is disposed on an exhaust downstream side of the exhaust turbine in an exhaust passage. The fuel addition device is configured to add a fuel to the exhaust gas of the engine to recover the function of the exhaust gas control apparatus on a further exhaust upstream side than the exhaust turbine. The heating unit is configured to heat the link chamber (). The ECU is configured to execute heating control for controlling the initiation and the stopping of heating by the heating unit and execute the heating control in a period overlapping with at least part of a period when the addition of the fuel by the fuel addition device is executed.
