METHOD AND SYSTEM FOR ENGINE TORQUE CONTROL

摘要

Methods and systems are provided for improving vehicle torque control accuracy. Data points of an engine torque data set are adjusted en masse by an on-board vehicle controller while also being adjusted individually by an off-board controller. By adjusting engine operation based on a torque data set that is updated by each of the on-board and off-board controllers, engine torque errors can be reliably determined and compensated for.

主权项

1. A method for controlling vehicle torque, comprising:
adjusting each data point of an engine torque data set with a slope and offset modifier from engine torque data on-board the vehicle; adjusting individual data points of the engine torque data set from engine torque data off-board the vehicle; and adjusting an engine airflow control based on the engine torque data set.
