Heat pump system and method for operating said system
Methods and systems are provided for operating a climate control system. In one example, a method for operating a vehicle climate control system includes modeling a pressure in a heat pump downstream of an exterior heat exchanger an upstream of an expansion valve. The method also includes operating the expansion valve to cool a vehicle cabin using the modeled pressure in conjunction with a temperature from a sensor positioned upstream of the expansion valve and downstream of the exterior heat exchanger.
Control system and method for an electronically governed engine of a refrigeration system
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.
Shift shock reduction control method of AMT vehicle
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).
METHOD AND AN APPARATUS TO DETERMINING AN IMPACT ON A TEMPERATURE-CONTROLLED UNIT
A server, an apparatus and a method for determining an impact on components of a temperature-controlled unit of a vehicle. The method includes receiving information of one or more parameters associated with one or more components of a temperature-controlled unit of a vehicle. Further, the information of the one or more parameters are received in response to a change in acceleration of the vehicle. The method also includes determining an impact on the one or more components of the temperature-controlled unit due to the change in the acceleration. The method further includes transmitting a notification to a device based on the impact on the one or more components of the temperature-controlled unit.
VEHICLE AIR CONDITIONING TORQUE RESERVE VIA BELT INTEGRATED STARTER GENERATOR
A vehicle includes an air-conditioning (AC) compressor, an engine, a belt-integrated starter generator (BISG), and a controller. The controller, responsive to detecting a first AC compressor engagement condition, compares a first AC torque demand that is required to engage the AC compressor with an available torque from the BISG. The controller further, responsive to the available torque being insufficient to engage the AC compressor, engages the AC compressor using the available torque from the BISG and an engine torque from the engine to compensate a torque shortfall between the AC torque demand and the available torque by retarding spark timing and increasing air intake.
TRANSPORT REFRIGERATION UNIT WITH VARIABLE-SPEED ELECTRIC REFRIGERATION DRIVE AND VARIABLE-SPEED DIESEL ENGINE SYNCHRONOUS GENERATOR POWER SOURCE
A transport refrigeration (TRU) system is provided and includes an air management system, a compressor, a generator which generates alternating current (AC) from operations of an engine to power operations of the air management system and the compressor and an AC inverter operably interposed between the generator and the compressor to decouple a drive frequency of the compressor from a frequency of the generator.
Integrated heat management system of vehicle
An integrated heat management system for a vehicle includes an air conditioner configured to cool or heat a passenger compartment using a refrigerant, a water-cooled cooling device configured to cool a specific device using the refrigerant of the air conditioner, and an air conditioning load change preventing unit configured to prevent a sudden change in an air conditioning load of the air conditioner when turning on or off the water-cooled cooling device with respect to the air conditioner.
Integrated thermal management systems and associated thermal control methods for electrified vehicles
This disclosure details integrated thermal management systems for thermally managing electrified vehicle components. Exemplary integrated thermal management systems may include a thermal module assembly that may be integrated into a front end structure of a flexible modular platform of the electrified vehicle. The integrated thermal management systems may be controlled in a plurality of distinct thermal control modes for thermal managing various subcomponents and for addressing various vehicle auxiliary loads (e.g., passenger cabin heating loads, passenger cabin cooling loads, etc.).
HEAT CONTROL DEVICE AND HEAT CONTROL METHOD
A heat control device is provided in a vehicle including a first thermal circuit that circulates a coolant and a second thermal circuit that circulates a refrigerant while changing the state of the refrigerant and is able to exchange heat with the first thermal circuit. When there is a heat discharge request from the second thermal circuit, the heat control device includes a determination unit configured to determine an amount of operation of each of a plurality of units which are used to discharge heat such that the heat discharge request is satisfied and the sum of power consumption values of the plurality of units is minimized.
VEHICLE CONTROL SYSTEM
A vehicle control system is provided, in which an engine ECU starts fuel cut control when deceleration is requested, and an air conditioner ECU operates a compressor to accumulate the cold while the fuel cut control operation is performed by an engine controller, and deactivates the compressor in a case where an evaporator temperature matches or falls below a compressor deactivatable temperature when a condition for terminating the fuel cut control is satisfied. The engine ECU extends the fuel cut control in a case where the compressor is deactivated when the condition for terminating the fuel cut control is satisfied. The air conditioner ECU includes an airflow volume decreasing unit configured to decrease an airflow volume from a blower, which blows air into a vehicle interior, when an estimated air conditioning load is low during the operation to accumulate the cold, for rapidly decreasing the evaporator temperature.
