ENGINE RESPONSE ADJUSTMENT

摘要

Methods and systems are provided for adjusting an engine output delivered in response to an operator pedal actuation based at least on a grade of vehicle travel. During uphill travel, in the presence of headwinds, and/or in the presence of a vehicle payload, the output may be increased while during downhill travel or in the presence of tailwinds, the output may be decreased. In this way, driver fatigue during travel over varying elevations, varying ambient conditions, and varying loads can be reduced.

主权项

1. A method for controlling a vehicle engine, comprising
determining a grade of vehicle travel and a wind amount; and during non-slipping and non-cruise vehicle conditions, adjusting a relationship between an operator accelerator pedal depression amount and an engine output torque based on the determined grade of vehicle travel and the wind amount.
