Abstract: An engine control system comprises a torque request module, an immediate torque control module, an actuation module, and an expected torque control module. The torque request module generates an expected torque request and an immediate torque request. The immediate torque control module controls a spark advance of an engine based on the immediate torque request. The actuation module selectively reduces the expected torque request based on the immediate torque request and a spark capacity. The spark capacity is based on a difference between a first engine torque and a second engine torque, determined at a current airflow. The first engine torque is determined at a first spark advance and the second engine torque is determined at a second spark advance that is less than the first spark advance. The expected torque control module that controls a throttle valve area based on the expected torque request.

Abstract: A method and system for regulating a drive torque provided to a driveline of a vehicle includes monitoring an accelerator pedal position and a brake pedal position. An adjusted accelerator pedal position is determined based on the accelerator pedal position and the brake pedal position and a drive torque request is determined based on the adjusted accelerator pedal position. Drive torque is generated based on the drive torque request.

Abstract: A method of regulating a torque output of a vehicle powertrain includes generating a plurality of torque requests and associating each of the plurality of torque requests with one of a plurality of arbitration domains to form torque request sets associated with each of the plurality of arbitration domains. A first torque request set is arbitrated within a first of the plurality of arbitration domains to provide a first torque request. The first torque request is introduced into a second torque request set associated with a second of the plurality of arbitration domains. The second torque request set is arbitrated within the second arbitration domain to provide a second torque request. A torque source is regulated based on the second torque request.

Abstract: A feedforward throttle adjustment for a closed loop idle speed control provides engine power output required to drive a variable power steering load while maintaining the engine idle speed in a desired range. The working pressure of the power steering system is detected, and the change in such pressure in the course of a steering maneuver is used to initiate an increase in the engine power output setting. The increase is determined in relation to the peak pressure change; it is implemented at a pedetermined rate, and is subject to interruption whenever the pressure change indicates that the steering maneuver has ended.
