An engine control system of a vehicle comprises a torque module and a chassis request evaluation module. The torque module controls a torque output of an engine based on a driver torque request and selectively increases the torque output based on a chassis torque request. The chassis request evaluation module selectively prevents the increase of the torque output based on at least one of a vehicle speed, a transmission state, and an accelerator pedal position.

Chassis system engine torque requests

A system for limiting the speed of a vehicle includes a first module that generates a first torque signal based on a vehicle speed, a second module that generates a second torque signal based on a difference between a predetermined vehicle speed limit and the vehicle speed, and a third module that generates an output torque signal based on the first and second torque signals. The output torque signal is adapted to control the output torque of a motor.
