摘要： Provided is a frequency determination unit that determines whether a prohibition frequency at which a drive source control unit prohibits a vehicle from being put in an EV priority mode is equal to or higher than a second threshold value when the vehicle has traveled between a predetermined location and a destination in the past in a state in which a specific target SOC is set to a value lower than a EV-SW permission SOC. When the frequency determination unit determines that the prohibition frequency is equal to or higher than the second threshold value and when the vehicle travels between the predetermined location and the destination, a low SOC control unit adjusts at least one of the specific target SOC and the EV-SW permission SOC such that the specific target SOC becomes a value that is equal to or higher than the EV-SW permission SOC.

摘要： 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 during operation when the fuel cut control is performed by an engine controller, and deactivates the compressor in a case where an evaporator temperature matches or falls below a predetermined value of a compressor deactivation permissible temperature when a condition of 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 of terminating the fuel cut control is satisfied. The air conditioner ECU includes a compressor deactivation permissible temperature changing unit configured to raise the compressor deactivation permissible temperature from the predetermined value when an estimated air conditioning load is low.

摘要： A processor is capable of executing low SOC control to set a particular target SOC, which is a target SOC for when a vehicle traveling from a first specific position along a first journey route arrives at a second specific position, to a value lower than the normal target SOC. The particular target SOC of the vehicle executing the low SOC control is a value of the EV-SW permissible SOC or greater in cases in which a prohibition frequency is a first threshold or greater, with the prohibition frequency being derived based on a total value of prohibition points representing the vehicle being prohibited from entering the EV priority mode due to the low SOC control.

摘要： An electrified vehicle includes an energy storage device, a temperature control device, and an electronic control unit. The energy storage device is configured to supply power to a driving source. The temperature adjustment device is configured to perform temperature adjustment of the energy storage device. The electronic control unit is configured to operate the temperature adjustment device when the temperature of the energy storage device falls within a temperature range in which the temperature adjustment is performed. The electronic control unit is configured to, when in a situation where charging is predicted to be performed after traveling of the electrified vehicle, set either an upper or lower limit of the temperature range using the state of charge of the energy storage device.

摘要： The battery cooling device that cools a battery by circulating a refrigerant by a compressor and cools air blown into a vehicle compartment, and when the battery is being rapidly charged, the rotation speed of the compressor is increased. More specifically, the upper limit rotation speed of the compressor is increased to a predetermined rotation speed. At this time, the predetermined number of revolutions is determined based on a maximum allowable noise level at the time of rapid charge of the battery.

摘要： 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.

摘要： A vehicle controller includes: a prediction unit that acquires position information on a parking place where parking time is predicted to exceed a prescribed threshold value in a travel route of the hybrid vehicle; and a target setting unit that sets a target state of charge of the battery and to change setting of the target state of charge from a first state of charge to a second state of charge that is lower than the first state of charge when the hybrid vehicle satisfies an approach condition to the parking place. A charge and discharge amount of the battery when the state of charge of the battery becomes equal to or less than the second state of charge is controlled to be smaller than the charge and discharge amount of the battery when the state of charge of the battery is larger than the second state of charge.

摘要： A control device for a hybrid vehicle includes: a prediction unit that acquires position information of a parking point where parking time of the hybrid vehicle on a travel route is predicted to exceed a threshold value; and a target setting unit that sets a target charge rate of the battery and changes the target chare rate to a second charge rate that is lower than a first charge rate in a normal state when the hybrid vehicle satisfies an approach condition of approaching the parking point. A charge and discharge amount is controlled such that a charge and discharge amount of the battery corresponding to the second charge rate when the target setting unit sets the target charge rate to the second charge rate is larger to a discharge side than a charge and discharge amount of the battery corresponding to the second charge rate in the normal state.
