Abstract
A system described is for providing improved cabin heating. The system may include a vehicle cabin heating system having a first and second heating system receiving coolant flow from the engine; and a control system for operating the engine at a first engine idle speed upon entering idle speed control operation from previous drive operation, maintaining said first idle speed for a duration, and then increasing engine speed to increase coolant flow to the second heating system during cold ambient conditions when the second heater system is in operation.
