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.

Method and system for engine start/stop control

A vehicle includes an engine cranked by an electric machine powered by a first battery, a first plurality of components powered by the first battery, a second plurality of components powered by a second battery, and a processor programmed to isolate the second battery and associated components from the first battery and associated components at least during engine cranking. The first battery may be a low voltage battery having a first chemistry, such as a lead-acid battery with associated components that are less sensitive to voltage variation induced by engine cranking or starting, such as heated mirrors, seats, wipers, a climate control blower, power windows/doors, and auxiliary pumps. The second battery may be a low or high voltage battery having a second chemistry, such as a lithium-ion battery with associated components that may be more sensitive to low voltage during engine cranking/starting, such as lighting, electronics, and infotainment systems.

System and method for powering start-stop and hybrid vehicle components and accessories

A vehicle according to the present disclosure includes an engine configured to autostop and autostart during a drive cycle. The vehicle additionally includes a user interface and a controller. The controller is configured to present on the user interface a metric indicative of a quantity of engine autostops during a drive cycle.
