A method of controlling an air-conditioning system of a vehicle when the vehicle is in an ignition-off state during vehicle stopping or parking, includes receiving, in the ignition-off state, a set air-conditioning time for operating an air-conditioning system of the vehicle and a set air-conditioning target temperature; determining the required air-conditioning energy for operating the air-conditioning system of the vehicle on a basis of the set air-conditioning time and a difference between the set air-conditioning target temperature and an outside temperature of the vehicle; and increasing, by the controller, a set minimum charge amount to be secured in a battery of the vehicle to secure the required air-conditioning energy.

An apparatus for controlling an engine of a vehicle includes an engine managing part to control warming up the engine at an initial start stage, and an air conditioning controlling part to request the engine managing part to perform an engine start, depending on whether the engine is warming up when control of air conditioning is necessary. The air conditioning controlling part continuously requests the engine managing part to perform the engine start to control the air conditioning until a warming up duration of the engine is terminated during the warning up of the engine.

Embodiments of this application disclose a vehicle thermal management system and method. The system includes a refrigeration cycle system, a coolant cycle system, and a control device, where the coolant cycle system includes a coolant cycle frontend radiator, a power assembly heat dissipation system, a battery pack heat dissipation system, a primary path water pump, a bypass water pump, and a valve bank system. In the system, the refrigeration cycle system is connected to the primary path water pump. Furthermore, in the system, the power assembly heat dissipation system and the battery pack heat dissipation system share the refrigeration cycle system and the coolant cycle frontend radiator by using the primary path water pump, the bypass water pump, and a combination of the valve bank system.

A thermal management system includes a refrigerant line including a compressor, a water-cooled condenser, and a cooling core for indoor air conditioning connected to the water-cooled condenser such that refrigerant emerging from the water-cooled condenser is introduced into the cooling core for indoor air conditioning, and a battery line including a high-voltage battery heat exchanging module and a heater core for indoor air conditioning. The battery line is connected to the refrigerant line through the water-cooled condenser in a heat exchangeable manner such that the high-voltage battery heat exchanging module and the heater core for indoor air conditioning are connected in parallel to the water-cooled condenser via a first valve to cause cooling water heated while passing through the water-cooled condenser to be selectively introduced into the high-voltage battery heat exchanging module or the heater core for indoor air conditioning.

A method of climate control in a vehicle includes cooling a battery and cabin of a vehicle at a target chiller-pump speed of a chiller. The target speed corresponds to a difference between a temperature of a battery and a target temperature of the battery. The target pump speed does not exceed a limit defined by a look-up table that identifies a capacity of the chiller by mapping the load and the difference.

There is disclosed a transport refrigeration system comprising an electronically governed engine that drives a refrigeration circuit of the system. The engine control unit is configured to operate the engine in a droop mode of operation, in which the engine speed increases with decreasing engine loads from the refrigeration circuit, so as to maximise the cooling capacity of the system at low engine load conditions.

An automated manual transmission (AMT) shift shock reduction control method may include a compressor delay control that is configured to keep an operation of a compressor as a non-operation state until a delay time is reached during a shift control, when an air conditioner signal and a shift signal are detected by an Engine Management System (EMS).

Disclosed is a transport refrigeration unit (TRU) having: an engine configured to power a refrigeration system of the TRU, the engine including an air intake, the engine within an engine compartment of the TRU; an air management valve (AMV) fluidly coupled to the air intake; a first duct fluidly coupled to the AMV and including a first inlet within the engine compartment; and a second duct fluidly coupled to the AMV and including a second inlet that is exterior to the engine compartment and is configured to receive atmospheric air; wherein: the AMV is configured to modulate air into the engine from the first duct and the second duct, when a temperature of air within the AMV is above the first threshold and the temperature of air within the second duct is below the first threshold, to lower the temperature of air entering the engine to below the first threshold.

A smart electric temperature-controlled system connected to a vehicle, such as a vehicle-transported refrigeration system, includes a power management system and an energy storage module. The power management system and energy storage module can manage power delivered to the temperature-controlled system components by monitoring temperatures and voltages (and possibly other factors) and by delivering power as a function of the things monitored. In a typical implementation the power management system and an energy storage module can supply power to a vehicle-transported refrigeration system when the vehicle is stopped and/or power from the vehicle electrical system is electrically isolated or otherwise unavailable.

A control method of an air conditioning system for compressor protection includes, when an air conditioner turn-on request is present, determining, by a controller, whether a compressor operating condition is satisfied from a refrigerant state of an air conditioner, when the compressor operating condition is determined as being satisfied, determining, by the controller, whether the vehicle is in a state of being unattended for a long period of time using information collected from a vehicle, when the vehicle is determined as being in a state of being unattended for a long period of time, performing, by the controller, pre-run control for operating the compressor in a predetermined minimum load condition; and when a pre-run operating time for which the compressor is operated in a minimum load condition reaches a predetermined pre-run holding time, interrupting, by the controller, the pre-run control with respect to the compressor.
