Abstract
Methods and systems are provided for controlling a boosted engine system, having a turbocharger and a charge air cooler, to limit overheating of a compressor outlet. In one example, a method includes predicting an engine torque profile based on current and future engine operating conditions. The method then models a compressor outlet temperature profile and reduces engine torque output to limit overheating of the compressor outlet.
Claims8
An engine method, comprising:
- estimating a compressor speed profile for a future horizon of vehicle operation based on current and predicted engine operating conditions, the compressor speed profile including a predicted compressor speed at each point of different time points of the future horizon;
- and
- adjusting an engine torque output responsive to each of a degree and a duration over which the predicted compressor speed, at a point of the different time points of the compressor speed profile, exceeds a threshold speed.
Dependencies are inferred from the claim text.
