Abstract
Methods and systems are provided for optimizing engine climate control performance and fuel economy in engines configured with start/stop capabilities. Climate control inhibits of start/stop actions are adjusted as a function of operator driving habits and climate control inputs and preferences. The approach enables climate performance to be improved while also allowing for frequent idle-stop operation.
Claims20
A method, comprising:
- adaptively adjusting a threshold for a parameter associated with idle-stop operation of an engine as a function of at least one of an operator drive history and operator cabin climate control preferences, the operator drive history and operator cabin climate control preferences learned over a plurality of drive cycles including a current drive cycle;
- and
- inhibiting the idle-stop operation responsive to a value of the parameter relative to the adjusted threshold.
A method, comprising:
- operating in one of a first mode that reduces inhibits of engine start/stop operation and a second mode that increases inhibits of the engine start/stop operation;
- and
- selecting between the first and the second mode based on operator drive history and operator cabin climate control preferences learned over a plurality of drive cycles including a current drive cycle.
A vehicle system, comprising:
- an engine;
- a heating, ventilation, and air conditioning (HVAC) system;
- and
- a controller storing executable instructions on non-transitory memory that, when executed, cause the controller to:
- adjust idle-stop conditions based on cabin climate control preferences of a current driver, the cabin climate control preferences learned over a plurality of drive cycles including the current drive cycle;
- enable idle-stop responsive to idle-stop conditions being met;
- and
- inhibit idle-stop responsive to idle-stop conditions not being met.
