摘要： Thermal management in a vehicle involves a compressor to output a refrigerant in vapor form for circulation in a refrigerant loop. A thermal management system includes a heating, ventilation, and air conditioning system in the refrigerant loop including an evaporator and an HVAC condenser, and an exterior condenser in the refrigerant loop configured to vent heat to an exterior of the vehicle. A first variable refrigerant flow valve controls a flow rate of the refrigerant output by the compressor into the HVAC condenser, and a second refrigerant flow valve controls a flow rate of the refrigerant output by the compressor into the exterior condenser. A controller controls the first refrigerant flow valve and the second refrigerant flow valve based on a target output temperature for the HVAC condenser.

摘要： A method of using a thermoelectric generator for warming a transmission on a vehicle having an internal combustion engine is provided. The method includes starting the internal combustion engine, thereby generating a hot exhaust gas; circulating coolant through a heating loop in fluid communication with the internal combustion engine and the thermoelectric generator; passing the hot exhaust gas through a hot-side of the thermoelectric generator and circulating the coolant through the cold-side of the thermoelectric generator, thereby transferring heat from the hot exhaust gas to the coolant and generating an electric current; and selectively powering an electric heating element with the electric current. The electric heating element is in thermal communication with a transmission fluid of the transmission. The coolant is circulated through the thermoelectric generator, by an auxiliary coolant pump powered by the electrical current, for a predetermined length of time after shutdown of the internal combustion engine.

摘要： A method and system used to identify an optimal hybrid vehicle operating mode based on a variety of potential factors, and then recommend the optimal operating mode to the driver so that they can make an informed decision regarding their operating mode selection. In one embodiment, the method uses geographic-, vehicle- and/or environmental-related factors to establish one or more operating zones, monitors the location of the hybrid vehicle and determines when it is within one of the operating zones, and then determines an operating mode that is optimal for that particular operating zone.

摘要： A vehicle includes a thermal energy management system with first and second thermal fluid loops. The first thermal fluid loop includes a coolant pump configured to circulate a coolant through a vehicle battery and a chiller. The second thermal fluid loop is configured to circulate a refrigerant through the chiller, a compressor, and at least one condenser. The controller is configured to control the thermal energy management system according to a passenger compartment cooling mode and a battery cooling mode. In the passenger compartment cooling mode the compressor is operated at a first power setting. In the battery cooling mode the compressor is operated at a second power setting and the chiller is controlled to transfer thermal energy from the first thermal fluid loop to the second fluid thermal loop. The second power setting is less than the first power setting.

摘要： A thermal management method and system in a vehicle include a chiller to cause heat transfer between a coolant loop that defines a path in which a coolant circulates and a refrigerant loop that defines a path in which a refrigerant circulates. The system includes an electronic expansion valve (EXV) in the refrigerant loop to control a flow of the refrigerant into a first part of the chiller, and a coolant pump in the coolant loop to control a flow of the coolant into a second part of the chiller. A controller controls the EXV and the coolant pump based on a target amount for the heat transfer.

摘要： A thermal energy management system for a vehicle supplies thermal energy to a passenger compartment of the vehicle. The thermal energy management system includes three thermal fluid loops. The first thermal fluid loop includes a coolant pump for circulating a coolant through at least a vehicle battery, a transmission oil cooler of the vehicle, and a chiller such that the coolant selectively transfers thermal energy from the vehicle battery, the transmission oil cooler, and the chiller. The second thermal fluid loop circulates oil through the transmission oil cooler. The third thermal fluid loop circulates a refrigerant through at least the chiller and at least one condenser such that the third thermal fluid loop transfers thermal energy to the passenger compartment.

摘要： A thermal management system having a first heating device, such as a rechargeable energy storage system (RESS), and a second heating device, such as an internal combustion engine (ICE), for a vehicle is provided. The system may allow waste heat within an ICE to be stored in a RESS, and may cool the RESS by depositing heat in the ICE. The RESS and the ICE are located in a first coolant circuit and a second coolant circuit, respectively. The system also includes a third coolant circuit interconnected with the first coolant circuit, and in thermal communication with the second coolant circuit via a first heat exchanger. The first and third coolant circuits are configured to circulate a first coolant, and the second coolant circuit is configured to circulate a second coolant. The RESS and the ICE are each configured to selectively operate as a heat source or a heat sink.
