摘要:
A system for heating and cooling a vehicle includes a solar panel disposed on a surface of a vehicle and a thermoelectric unit i) disposed on or in an internal surface disposed in a cabin area of the vehicle, and ii) operatively connected to the solar panel. The thermoelectric unit is configured to heat and/or cool the internal surface in response to electric current applied thereto from the solar panel. The system further includes a control unit operatively associated with the thermoelectric unit. The control unit is configured to determine the amount and direction of the electric current to be applied to the thermoelectric unit based on i) a measured ambient temperature, ii) a measured temperature of the internal surface, and iii) a user-preferred reference temperature.

A system and method for controlling air flow through a passenger cabin and battery pack of a vehicle having a battery module is disclosed. A HVAC controller communicates with a battery pack controller to assure that air flow from the passenger cabin through the battery pack, and either out to atmosphere or returned to the passenger cabin, is coordinated to obtain desirable passenger cabin heating/cooling and battery cooling.

A seat temperature control system having a temperature controlled seat for use in a vehicle is disclosed. The temperature controlled seat may comprise a seat bottom, a seat back and an air conditioning system. The seat bottom includes a bottom heat exchanger fluid coil configured to direct a cooling fluid therethrough from a bottom inlet end to a bottom outlet end. The seat back includes a back heat exchanger fluid coil configured to direct the cooling fluid therethrough from a back inlet end to a back outlet end. The air conditioning system includes a coils inlet line in fluid communication with the bottom inlet end and the back inlet end, and a coils outlet line in fluid communication with the bottom outlet end and the back outlet end. The air conditioning system provides cooling fluid to the coils and receives cooling fluid from the coils.

The method for thermal management of a battery can include vehicle systems to control the thermal input to the battery and a dedicated battery thermal management system. The battery thermal management system includes transferring battery heat to coolant flowing in a circuit, if ambient air temperature is greater than the battery temperature, using an evaporator/chiller to transfer heat from the coolant to a refrigerant, using a condenser to transfer heat from the refrigerant to the coolant, and using a radiator to transfer heat from the coolant to ambient air; and if coolant can be maintained in the reference temperature range without using a heat source or refrigerant, using a radiator to transfer heat from the coolant to the ambient air.

An HVAC system, and a method of operation, for use in a vehicle is disclosed. The HVAC system may comprise: an evaporator having a drain that receives condensate dripping from the evaporator; a refrigerant compressor that receives a refrigerant from the evaporator and compresses the refrigerant; a condenser that receives the refrigerant from the compressor; and a condensate-to-refrigerant heat exchanger that receives the refrigerant from the condenser and the condensate from the drain, whereby the condensate absorbs heat from the refrigerant as the condensate flows through the condensate-to-refrigerant heat exchanger.

A steering assembly and HVAC system, and method of operation, for a vehicle is disclosed. The system may comprise a steering column assembly including a steering column located within a cowl; a steering wheel assembly including a hub operatively engaging the steering column; and a steering assembly HVAC system including a steering column HVAC duct extending along the cowl and having an air outlet adjacent to the hub, whereby air will flow through the steering column HVAC duct and through the air outlet past the hub.
摘要:
A system and method of operating a vehicle air conditioning system having an engine driven, fixed capacity refrigerant compressor and a compressor clutch is disclosed. The method may comprises setting a preliminary evaporator air temperature target; charging a cold storage apparatus in the vehicle air conditioning system; determining if the cold storage apparatus has reached a predetermined threshold; if the cold storage apparatus has reached a predetermined threshold, determining a new evaporator air temperature target by: determining a maximum allowable dewpoint evaporator air temperature for maintaining a passenger compartment humidity below a predetermined value; determining a maximum allowable mode evaporator air temperature based on a mode to which the vehicle air conditioning system is set; and setting the evaporator air temperature target to the lower of the dewpoint evaporator air temperature and the mode evaporator air temperature. The compressor clutch is controlled to achieve the evaporator air temperature target.
摘要:
A belt alternator starter (BAS) system for a hybrid vehicle may include a first pulley, a first belt, a motor generator unit (MGU), a second pulley, a second belt, and a first clutch. The first belt encircles the first pulley and a crankshaft pulley of an internal combustion engine. The MGU includes the second pulley and functions as an electric motor when the engine is started and as a generator for charging a battery when the engine is running. The second belt encircles the second pulley and at least one drive pulley of an accessory unit. The first clutch couples/decouples the crankshaft pulley to/from the second pulley depending on operation of the engine.
摘要:
A method for controlling a fan in a vehicle includes comparing the current temperature of at least a first device and a second device to multiple temperature ranges for each of said devices and determining on the basis of said comparisons whether fan speed should be changed, increasing fan speed to a maximum fan speed if at least one of the comparisons indicates that the maximum fan speed is desired, increasing fan speed to a reference fan speed if at least one of the comparisons indicates that an increase in fan speed less than the maximum fan speed is desired, and decreasing fan speed to a reference fan speed if the comparisons indicate that a decrease in fan speed is desired.
摘要:
A cooling system dedicated to cooling the vehicle components located in the rearward portion of a vehicle is provided. The rear-dedicated cooling system operates independently of any cooling systems located in a frontward portion of the vehicle. The rear-dedicated cooling system may be subdivided into high temperature and low temperature cooling circuits. A method of cooling a vehicle is also provided.
