Engine control systems and methods for future torque request increases

机译:未来扭矩需求增加的发动机控制系统和方法

摘要

An engine control method includes: generating a torque request for an engine based on a driver input; and based on the torque request, controlling: opening of a wastegate of a turbocharger; opening of a throttle valve based on the torque request; and an intake valve phaser and an exhaust valve phaser. The engine control method also includes selectively determining an expected future increase in the torque request. The engine control method also includes, based on the expected future increase and before the torque request increases based on the expected future increase: decreasing the opening of the wastegate; and at least one of: decreasing the opening of the throttle valve; and adjusting at least one of the intake valve phaser and the exhaust valve phaser to decrease a volumetric efficiency of the engine.
