Abstract: The intent of this invention is to minimize the possibility of exhausting the vehicle battery while still permitting operation of specific accessories with the engine off. The invention proposes to accomplish this by powering and terminating the operation of an accessory through and under the control of any type of no idle HVAC system or as a free standing auxiliary, accessory powering system having its own means of termination.

Abstract: An energy recovery interior heating system has a modified mechanical or electrical drive isolation system for vehicles such as trucks. This permits a standard air conditioning compressor pump to be driven from multiple power inputs thereby providing any hybrid or non-hybrid vehicle with continuous engine-on heating and/or air conditioning, limited time engine-off heating and air conditioning and two types of engine-off air conditioning temperature modulation. Another combination of the heating and air conditioning systems would permit the continuation of heating and cooling on hybrid vehicles when they are stationary and their traction batteries are fully charged and the vehicle is operating only on the electric motors for traction or work load power. This invention also provides internal combustion engine-off heating and A/C on these types of vehicles. Another embodiment uses the drive isolation system to integrate auxiliary power unit (APU) functions as part of the traction engine of over the road trucks.

Abstract: An after-run heating system for a vehicle includes a pump and a control circuit therefor located in the engine compartment and a separate vehicle fan control circuit located in the passenger compartment. The after-run heating system is configurable at the time of installation as an interconnected system or as a divided system. The interconnected system has direct electrical connections between the control circuits. The divided system has no mechanical, electrical or electromagnetic connections between the control circuits. The components in both the engine and passenger compartments function co-dependently, either as an interconnected system or as a divided system.

Abstract: A relay connecting means comprising a loose terminal connector mounted on a thin substrate carrier. The loose terminal connector comprising displaceable tabs being engagable with the terminal blade of the automotive plug-in relay. The loose terminal connector may further comprise a wire connecting post for connecting a wire conductor thereto.

Abstract: A system for continuing heating of a vehicle interior after the engine which normally controls the heating of the vehicle has been turned off. The system comprises a first control circuit located in the engine compartment of the vehicle which continues to pump heated engine coolant through the heater core of the vehicle after the engine has been turned off. A second control circuit located in the passenger compartment of the vehicle continues to operate the heater fan which blows air through the heater core and into the passenger compartment after the engine has been turned off. Thermostats in each circuit are operative to disconnect the battery when the coolant temperature is no longer effective to heat the passenger compartment. The first and second control circuits have no mechanical, electrical or electromagnetic interconnection therebetween.
