摘要： A heat circuit may include a controller configured to execute a first process and then a defrosting operation. The first process may be a process to execute a first air-heating operation and a heat storage operation simultaneously. The second process may be a process to execute a defrosting operation. The controller may be configured, in the first air-heating operation, to cause the radiator to heat a radiator passage and cause the air-heating apparatus to heat air using heat of a air-heating passage while circulating the heat medium in the radiator passage and the air-heating passage. The controller may be configured, in the heat storage operation, to circulate the heat medium in an electrical apparatus passage and a bypass passage. The controller may be configured, in the defrosting operation, to circulate the heat medium in the electrical apparatus passage and the radiator passage.

摘要： A heat management system disclosed herein is used for an electric vehicle. The heat management system may include an oil cooler, an oil pump, a converter cooler, a first heat exchanger, a second heat exchanger, a first channel, a second channel, a channel valve, a bypass channel, and a controller. The channel valve may be configured to select a first valve position and a second valve position. The bypass channel may be configured to allow the first heat medium to bypass the first heat exchanger and circulate between the oil cooler and the converter cooler when the second valve position is selected. The controller may be configured to control the channel valve such that the channel valve selects the first valve position and activate the oil pump in response to the temperature of the first heat medium in the first channel becoming higher than a predetermined upper limit temperature.

摘要： A thermal management device includes a first thermal circuit, a second thermal circuit, and a control unit. The first thermal circuit includes a first radiator and a battery. The second thermal circuit includes a heater, a temperature sensor, a first path, a second radiator, a second path, a heating appliance, and a flow rate adjusting unit. When a battery heating request and an air heating request are made, the control unit heats a second thermal transfer medium, and divides the flow of the second thermal transfer medium to the first and second paths. When a deficiency value of measured temperature with respect to a target temperature of the second thermal transfer medium is greater than a first threshold value in flow dividing processing, a second flow dividing proportion of the second path is set to be greater than a first flow dividing proportion of the first path.

摘要： A control apparatus for a hybrid electric vehicle includes: an engine control portion configured to control an operation state of an engine in accordance with an engine operation condition; and a driving-mode control portion configured to control the vehicle so as to realize selected at least one of driving modes. The driving modes include a towing mode in which the vehicle tows a towed vehicle, a main-drive-wheel driving mode in which a drive power is distributed to main drive wheels, and an all-wheel driving mode in which the drive power is distributed to the main drive wheels and auxiliary drive wheels. The engine operation condition is determined such that an engine operation ratio is higher in a case in which the towing mode is selected, than in a case in which the all-wheel driving mode is selected without the towing mode being selected.

摘要： A vehicle-mounted temperature controller includes a first heat circuit and a refrigeration circuit. The first heat circuit has a battery heat exchange part exchanging heat with a battery and a first heat exchange part, and configured so that a first heat medium circulates therethrough. The refrigeration circuit has a compression part compressing a refrigerant to raise its temperature, a second heat exchange part radiating heat from the refrigerant, an expansion part making the refrigerant expand, and the first heat exchange part making the refrigerant absorb heat from the first heat medium to make the refrigerant evaporate, and is configured to realize a refrigeration cycle by the refrigerant circulating therethrough. The first heat circuit includes a bypass flow path bypassing the battery heat exchange part and an adjusting device adjusting a flow rate of the first heat medium flowing through the bypass flow path. The adjusting device is controlled so that a ratio of a flow rate of the first heat medium flowing through the bypass flow path becomes greater, when the temperature of the battery is relatively low, compared to when it is relatively high.
