Temperature control strategy for a rear control system
View Patent ↗The present invention provides a heating/cooling control system that can effectively control the temperature of the air discharged at the rear interior of the motor vehicle. The heating/cooling control system includes a front control and a rear control. The front control is capable of operating within a predetermined temperature range. The temperature range of the rear control is based on the set point of the front control.
1. A heating and cooling control system for heating and cooling the interior compartment of a motor vehicle, the system comprising:
an air flow system defining therein an air passageway to the interior compartment;
a blower for forcing air through the air passageway towards the interior compartment;
a front controller for controlling temperature of air discharged towards a front interior compartment, the front controller configured to operate within a pre-determined temperature range and having a temperature set point within the pre-determined temperature range; and
a rear controller for controlling temperature of air discharged towards a rear interior compartment, the rear controller being configured to define a temperature range that is a subset of the pre-determined temperature range based on the temperature set point.
2. The system of claim 1 , wherein the temperature set point is the lowest temperature of the pre-determined temperature range.
3. The system of claim 2 , wherein the temperature range defined by the rear controller only includes temperatures that are greater than or equal to the temperature set point.
4. The system of claim 1 , wherein the temperature set point is the highest temperature of the pre-determined temperature range.
5. The system of claim 4 , wherein the temperature range defined by the rear controller only includes temperatures that are less than or equal to the temperature set.
