20100206957 | SYSTEM AND METHOD FOR VEHICLE TEMPERATURE CONTROL - A vehicle includes a power connector configured to mate with an electrical power grid receptacle and receive a grid power therefrom and a heating and cooling system electrically connected to the power connector to receive grid power therefrom and configured to modify a temperature the vehicle cabin. The vehicle also includes a temperature control loop configured to selectively activate and control the heating and cooling system and a controller configured to receive a first input signal comprising a desired vehicle activation time and a second input signal comprising a starting vehicle cabin temperature and a desired vehicle cabin temperature. The controller determines a temperature control loop activation time based on the first and second input signals that is prior to the desired vehicle activation time and transmits an activation signal to the temperature control loop at the temperature control loop activation time to activate the heating and cooling system. | 08-19-2010 |
