Abstract:
1. A multiple zone electronic control system to control a heating, ventilation and air conditioning (HVAC) system for a vehicle comprising: a plurality of sensors to provide inputs relating to multiple zones of an occupant compartment of the vehicle; a plurality of buttons to provide manual inputs relating to the multiple zones; a plurality of mechanisms to control temperature and flow of air from the HVAC system into the multiple zones; and a controller electrically connected to said sensors and said buttons to receive the inputs therefrom and calculating a driver side blend function, rear blend function and passenger side blend function wherein the rear blend function is a calculation based on the driver side blend function and the passenger side blend function and interpolating outouts based on a blend linear interpolation for each blend function, said controller electrically connected to said mechanisms to control the temperature and flow of air into each of the multiple zones.
