Patent Images
1. Method for controlling throttle change in an internal combustion engine powered vehicle, comprising:
- providing a throttle actuation limit substantially corresponding to an operator selected throttle pedal angle;
providing a requested throttle actuation corresponding to an automated throttle position control; and
limiting the rate of change of the throttle when the requested throttle actuation is above said throttle actuation limit.

Abstract
A throttle limit control for an internal combustion engine throttle control is disclosed. Rate limiting is applied to prevent excessive rates of change in throttle actuation. Throttle pedal authority is continually maintained and throttle headroom is not compromised thereby. Application to various systems including conventional and adaptive cruise systems and power take-off systems is envisioned.

12. Method for controlling a throttle in an internal combustion engine, comprising:
-
providing a first throttle actuation request substantially corresponding to an operator selected throttle pedal angle; providing a second throttle actuation request corresponding to an automated throttle position control; effecting throttle changes substantially in accordance with said first throttle actuation request when said first throttle actuation request exceeds said second throttle actuation request; and rate limiting throttle changes when said first throttle actuation request does not exceed said second throttle actuation request. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 24)
