Abstract
An improved motor vehicle automatic climate control methodology individually develops climate control commands in response to ambient environmental conditions and a transient state estimator, and individually and adaptively adjusts the commands to improve driver comfort in response to driver override of respective automatic control settings. The adaptive adjustment of the climate control commands is carried by CMAC neural networks that take into account the environmental conditions and the dynamic state of the system when the respective overrides occur so as to minimize or eliminate the environmental state ambiguity and steady-state/transient coupling that occur in currently known control methodologies.
Claims16
A method of operation for an automatic climate control system for a cabin of a motor vehicle, comprising the steps of:
- measuring environmental conditions including ambient temperature and solar loading;
- estimating a transient state of said automatic climate control system based on a soak temperature of said cabin upon commencement of a period of vehicle operation and a nominal steady-state temperature of said cabin;
- developing baseline control settings for each of a plurality of climate control parameters based on the measured environmental conditions;
- detecting driver overriding of one or more of said climate control parameters;
- and
- in response to said detected driver overriding:
- modifying the baseline control setting for each overridden climate control parameter;
- storing a training example based on the driver overriding, the measured environmental conditions, and said estimated transient state when the overriding occurs;
- and
- revising an adaptive adjustment of the baseline control setting for each overridden climate control parameter based on the stored training example.
