Abstract

A Start-Stop method and system for optimizing a selected set of parameters to provide an ideal balance between cabin thermal comfort and fuel economy performance is disclosed. The method and system include several parameters to manage how long and when the engine OFF time will occur. Such parameters include, but are not limited to, outside ambient temperature, cabin temperature, cabin humidity, engine coolant temperature, and evaporator thermistor temperature. A control logic monitors inputs such as cabin humidity and, under certain conditions, sends a request for the engine to be ON. Other factors influencing engine ON time include inputs from the wiper(s), the heated windshield, the heated back light, the HVAC blower, and the temperature control setting. The disclosed system has utility in both electronic automatic temperature control (EATC) systems as well as in manual temperature control (MTC) systems.
