Abstract
Methods and systems are presented for improving performance of a vehicle operating in a cruise control mode where a controller adjusts torque output from a vehicle to maintain vehicle speed within a desired range. The methods and systems include adapting a vehicle dynamics model and a vehicle fuel consumption map that provide input to nonlinear model predictive controller.
Claims20
An engine operating method, comprising:
- adjusting an estimated vehicle coasting duration via a controller based on responses of a peer group of human drivers;
- and
- automatically stopping an internal combustion engine via the controller responsive to the estimated vehicle coasting duration.
An engine operating method, comprising:
- assigning a machine learning model to a peer group of drivers;
- adjusting an estimated vehicle coasting duration based on responses of the peer group of human drivers;
- and
- automatically stopping an internal combustion engine responsive to the estimated vehicle coasting duration.
1 more element
An engine control system, comprising:
- an internal combustion engine;
- a distance to object sensing system that transmits a signal and receives a reflected version of the signal;
- and
- a controller including executable instructions stored in non-transitory memory to estimate a vehicle coasting duration and stop the internal combustion engine based on the vehicle coasting duration, the vehicle coasting duration estimated based on vehicle coasting durations of a predetermined peer group of human drivers, the vehicle coasting duration a function of responses of members of the predetermined peer groups during conditions where performance of the distance to object sensing system is degraded due to environmental conditions.
