Abstract: 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.

Abstract: The disclosure herein provides a heat management system for a vehicle, comprising: a first heat circuit in which first heat medium flows; a second heat circuit in which second heat medium flows; and a main heat exchanger configured to transfer heat from the second heat medium to the first heat medium. The first heat circuit comprises: a compressor; a cabin heater; a first air heat exchanger; an evaporator; a first bypass channel configured to allow the first heat medium to bypass the main heat exchanger; and a first switching valve by which one of the main heat exchanger and the evaporator is selected as a flow destination of the first heat medium flowing out from the first air heat exchanger. A single heat circuit (the first heat circuit) can achieve both heating and cooling of the air in the cabin.

Abstract: 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.

Abstract: The cooling apparatus of the engine according to the invention supplies the cooling water directly to the cylinder block water passage from the cylinder head water passage when the engine temperature is between first and second temperatures, and a supply of the cooling water to the heat exchanger is not requested. The first and second temperatures are lower than the engine completely-warmed temperature. The apparatus supplies the cooling water discharged from the cylinder block and head water passages, to the water passages through the heat exchanger when the engine temperature is between the second temperature and the engine completely-warmed temperature, and the supply of the cooling water to the heat exchanger is not requested.

Abstract: A jump shift of an automatic transmission with multiple shift speeds such as, e.g., ten forward speeds involves operation of many engagement elements. The shifting operation for the jump shift is therefore complicated, making it difficult for the automatic transmission to respond quickly. After shifting to the seventh speed as a direct coupling speed is completed by engaging three clutches C1, C3, C4, the remaining other clutch C2 is also engaged at the seventh speed. In the case of a jump shift, e.g., a shift from the seventh speed to the fifth speed, shifting to the fifth speed is completed by disengaging the clutch C1 and performing control to disengage the clutch C3 and to engage a brake B1 with the remaining other clutch C2 kept in the engaged state. This facilitates the shifting operation from the direct coupling speed and allows the automatic transmission to respond quickly.
Abstract translation: 具有多个换档速度（例如十个前进速度）的自动变速器的跳跃转换涉及许多接合元件的操作。 因此，跳跃移位的换档操作变得复杂，使得自动变速器难以快速响应。 在通过接合三个离合器C1，C3，C4来完成直接联接速度之后，转速到第七速度后，剩下的另一个离合器C2也以第七速度接合。 在跳跃换档的情况下，例如，从第七速度向第五速度的变速，通过使离合器C1脱离并执行控制以使离合器C3脱离并将制动器B1与剩余的制动器B1接合来完成向第五速度的转换 其他离合器C2保持在接合状态。 这有助于从直接耦合速度的换档操作，并允许自动变速器快速响应。

Abstract: 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.

Abstract: A vehicle-mounted temperature controller includes a low temperature circuit and a refrigeration circuit. The low temperature circuit has a heat generating equipment heat exchanger exchanging heat with heat generating equipment, a radiator, a first heat exchanger, and a three-way valve. The refrigeration circuit has a second heat exchanger discharging heat from the refrigerant to a high temperature circuit to make the refrigerant condense, and the first heat exchanger making the refrigerant absorb heat from the cooling water to make the refrigerant evaporate. The low temperature circuit includes a first partial circuit through which the cooling water flows through the radiator and the first heat exchanger, and a second partial circuit through which the cooling water flows through the heat generating equipment heat exchanger without passing through the radiator and the first heat exchanger. The cooling water circulates simultaneously and separately at these first partial circuit and second partial circuit.

Abstract: The control device of the vehicle performs slip control for engaging the connection and disconnection clutch as an instruction hydraulic pressure for engaging the connection and disconnection clutch by the hydraulic control mechanism after the internal combustion engine is started by the starter, as an instruction hydraulic pressure for maintaining the speed of the internal combustion engine at a higher speed than a lower limit speed for avoiding the stop of the internal combustion engine. Further, the control device of the vehicle performs engagement completion control of raising an instruction hydraulic pressure for engaging the connection and disconnection clutch from an instruction hydraulic pressure in the slip control to an instruction hydraulic pressure for completing engagement of the connection and disconnection clutch when a difference between the speed of the internal combustion engine and the speed of the electric motor becomes smaller than a preset threshold value.
