A vehicle thermal management system may include a cooling apparatus including a radiator, a first water pump, and a valve which are connected through a coolant line, a battery cooling apparatus including a second water pump and a battery module connected by a battery coolant line; a chiller which is connected to the battery coolant line and connected to an air conditioner through a refrigerant connection line which is connected to the battery coolant line and connected to a refrigerant line of an air conditioner through a refrigerant connection line, to adjust a temperature of the coolant by performing heat exchange between a coolant which is supplied to the battery line and a refrigerant which is selectively supplied from the air conditioner; and a heating circuit of warming an interior of the vehicle by use of the coolant having a temperature.

A heat pump system for a vehicle may use one chiller in which the coolant and the refrigerant are heat-exchanged to heat or cool the battery module, the system may be simplified and the heating efficiency may be improved by selectively using the external heat and the waste heat of the electrical component and the battery module in the heating mode of the vehicle.

Methods and systems for providing control of a heat pump of a motor vehicle are presented. In one operating mode, speed of a heat pump compressor is controlled responsive to an outlet pressure of the heat pump compressor. In a second operating mode, speed of the heat pump compressor is controlled responsive to a pressure ratio between an inlet and an outlet of the heat pump compressor.

A heat pump system for a vehicle may heat or cool a battery module by use of a chiller in which a refrigerant and a coolant are heat-exchanged, and may improve heating efficiency by use of another chiller that recovers waste heat of electrical equipment.

A vehicle includes a climate control system to thermally precondition a passenger cabin and a controller programmed to obtain a vicinity temperature from a vehicle sensor and receive location temperature data from a remote source. The controller is also programmed to activate the climate control system in advance of an upcoming trip and to set a first precondition criteria based on the vicinity temperature when the vicinity temperature is within a threshold range of the location temperature data. The controller is further programmed to set a second precondition criteria based on the location temperature data when the vicinity temperature is outside of the threshold range.

A vehicle climate system includes a blower and a controller. The controller is configured to, responsive to input of a particular user selected climate setting, operate the blower with an initial power having a predetermined value corresponding to the climate setting provided that cabin temperature is outside a predetermined range. The controller is also configured to operate the blower with an initial power having a value less than the predetermined value provided that the cabin temperature is within the predetermined range.

The first vane valve assigned to the first air outlet channel, and the second vane valve assigned to the second air outlet channel, the first vane valve and the second vane valve being rotatably fixedly connected to a shaft and being rotatable by an actuator driving the shaft.

The present invention relates to a fluid line system (10) for guiding fluid, in particular for a motor vehicle. The fluid line system (10) comprises a sensor device (20) for capturing sensor parameters and a housing (30), which has two or more housing parts (40, 60). Each housing part (40, 60) has a mounting surface area (50, 70) for arranging a further housing part (40, 60). The housing (30) further has a groove arrangement (80), which comprises at least one groove recess (90), which is arranged on a mounting surface area (50, 70), wherein a groove recess (90) has a groove opening (95), which opens out to the respective mounting surface area (50, 70). In any case, the groove opening (95) is closed by in a fluid-tight manner means of the mounting surface area (50, 70) of at least one further housing part (40, 60). It is attained thereby that a fluid duct (99), through which fluid can flow and through which fluid can be applied to the sensor device (20), is limited between the respective groove recess (90) and the respective mounting surface area (50, 70).

A vehicle-mounted temperature controller includes a first heat circuit having a heat exchanger for a heat generating device and a first heat exchanger; a second heat circuit having a heat medium flow path of an engine and a second heat exchanger; and a refrigeration circuit having the first heat exchanger to make the refrigerant evaporate and the second heat exchanger to make the refrigerant condense. A circulation mode control device control a circulation mode so that the second heat medium raised in temperature by absorbing heat from the refrigerant at the second heat exchanger flows into the flow path, when the engine is stopped and heat is discharged from the heat generating device to the first heat medium in the heat exchanger for the heat generating device and heat is absorbed from the first heat medium to the refrigerant in the first heat exchanger.
