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.

An engine control system comprises a first torque request module that generates a first torque request, a second torque request module that generates a second torque request, a torque arbitration module, an arbitration feedback module, and a torque control module. The torque arbitration module selects one of the first and second torque requests and outputs an arbitrated torque based on the selected one of the first and second torque requests. The arbitration feedback module reports a status signal to the first torque request module. The status signal has a first value when the first torque request is the selected one of the first and second torque requests. The torque control module controls an engine to produce the arbitrated torque. The power source includes an internal combustion engine.

An engine control system of a vehicle comprises a reserves module and a fault diagnostic module. The reserves module controls airflow into an engine based on a driver torque request, increases the airflow into the engine when a reserve torque request is received, and outputs a torque output command for the engine based on the driver torque request. The fault diagnostic module selectively diagnoses a fault in the reserves module when the torque output command is greater than a sum of the driver torque request, a predetermined torque, and a load applied to the engine.

An engine control system comprises a derivative module and a slip remediation module. The derivative module determines a mathematical derivative of a driven wheel speed of a vehicle. The slip remediation module, when the mathematical derivative is more negative than a predetermined deceleration, at least one of disables regenerative braking being performed by one or more electric motors, increases an axle torque request, and unlocks a torque converter.

A method of controlling torque on a vehicle wheel axle includes comparing a torque intervention request to a predetermined minimum axle torque for a current vehicle speed and a current direction of motion of the vehicle. The predetermined minimum axle torque decreases as vehicle speed in an operator-selected direction of motion increases. An arbitrated axle torque is calculated based on an operator-requested torque, the current vehicle speed, the current direction of motion, and the greater of the torque intervention request and the predetermined minimum torque. Axle torque is applied to the vehicle's wheel axle based at least partially on the arbitrated axle torque.

An engine system includes a throttle actuator module and a torque control module. The throttle actuator module controls a throttle actuator based on a desired throttle area. The torque control module determines an actuator torque. The torque control module determines a rate limited torque, a maximum torque, and a minimum torque based on the actuator torque and a predetermined rate of change. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is greater than the maximum torque. The torque control module determines the desired throttle area based on the actuator torque when the rate limited torque is less than the minimum torque.
