摘要:
By employing a heat source control section that controls the operating state of an internal combustion engine mounted in a vehicle, a necessary heat calculating section that calculates the engine coolant temperature needed by a heater core, which consumes the heat supplied from the engine through engine coolant water, and the time at which this engine coolant temperature becomes necessary, a heat supply estimating section that estimates engine coolant temperature at the aforementioned time in a case in which the engine is operated continuously in the current operating state, and a heat generation increase requesting section that requests the heat source control section to increase heat generation quantity of the engine when the engine coolant temperature estimated by the heat supply estimating section is less than the engine coolant temperature calculated by the necessary heat calculating section, the heat necessary for the heater core is supplied more efficiently and adequately.
摘要:
An engine and an electronic control unit perform cooling capacity increase control for compensating for a insufficiency of the cooling capacity of a cooling device. The electronic control unit performs a variety of control for a vehicle, including control of the cooling device. At that time, the electronic control unit calculates the target value of the cooling capacity of the cooling device, calculates the estimate value of the cooling capacity that will be able to be exerted in the future under the current control, compares the target value and the estimate value, and when it is determined from the result of the comparison that the cooling capacity will be insufficient, performs the cooling capacity increase control. The electronic control unit changes the contents of the cooling capacity increase control according to the degree of insufficiency of the estimate value with respect to the target value.

In a hybrid vehicle 20, an engine 22, motors MG1 and MG2 are controlled so that the engine 22 is operated at a target operation point set at Step 120 based on a torque demand Tr* and the motor MG2 outputs lower power for driving in comparison with a turn-off condition of an ECO switch 88 when the ECO switch 88 is turned on upon driving with power from both the engine 22 and the motor MG2 (Steps S130-S150 and S170-S200).
摘要:
During the period of deceleration of a vehicle, an air conditioning control unit modifies a target cooling temperature (TEO) of an evaporator to a temperature lower than that before the deceleration by γ ° C. in order to store cold in the evaporator (step S130). When the vehicle comes to rest, the air conditioning control unit sets an upwardly-modified target temperature TEOK, which is a temperature modified toward more or less higher temperatures from the target cooling temperature TEO, and brings a compressor to rest and keeps the resting state of the compressor until a detected temperature TE of an evaporator discharge temperature sensor exceeds TEOK (step S180). Therefore, it is possible to effectively utilize the cold heat stored in the evaporator 6 during the period of deceleration of the vehicle with a good feeling of passengers being maintained while the vehicle is at rest.
