  • Patent number: 11965665
    Abstract: An air conditioning system includes an air conditioning apparatus, and a controller. The air conditioning apparatus performs air conditioning of an air-conditioning target space. The controller is connectable to a plurality of types of thermostats. The controller performs communication with the thermostat connected thereto. The controller performs a performance determination process for the refrigeration cycle apparatus. The controller performs different performance determination processes according to whether a first type of thermostat is connected thereto unit or whether a second type of thermostat is connected thereto. Alternatively, the air conditioning apparatus changes a method for using information received by the controller from the thermostat according to whether being in a determination processing time over which the performance determination process is performed or in a non-determination processing time over which the performance determination process is not performed.

  • Patent number: 10661779
    Abstract: A control system for a hybrid vehicle configured to generate a required power continuously even if a large power is required frequently. An operating mode of the hybrid vehicle is selected from HV mode and EV mode, and in the hybrid vehicle, a drive power established by generating maximum output power of the engine is smaller than a drive power established by supplying a maximum electric power to the motor from the electric storage device. A controller is configured to shift the operating mode from the EV mode to the HV mode when an SOC level of a battery falls below a threshold level, and to raise the threshold level when a required running condition in the electric vehicle mode is a condition that cannot be achieved by the engine without operating the motor given that the hybrid vehicle is propelled in the hybrid mode.

  • Patent number: 10351122
    Abstract: A vehicle control apparatus includes an electronic control unit. The electronic control unit is configured to perform feedback control of a motor such that a torque is output for stopping a crankshaft at a target angle. A first angle is used as the target angle during a first period from start of the feedback control to first detection of rotation of the crankshaft in a negative rotational direction for returning the crank angle. A second angle is used as the target angle during a second period from the lapse of the first period to detection of a changeover in a rotational direction of the crankshaft from the negative to a positive rotational direction. The electronic control unit is configured to return the target angle to the first angle at a first timing after the lapse of the second period.

  • Patent number: 10029675
    Abstract: A control device for a hybrid vehicle is, in the process of stopping an internal combustion engine of the vehicle, capable of making twist angle fluctuation reduction control and crank angle position control mutually compatible. When a request for stopping the internal combustion engine has been issued, twist angle fluctuation reduction control is implemented without implementing crank angle position control, until, in the process of bringing the engine to a stopped state, the rotational speed of the internal combustion engine drops below the resonant rotational speed region of the torsional damper; and, after the rotational speed of the internal combustion engine has dropped below the resonant rotational speed region of the torsional damper in the process of bringing the engine to a stopped state, crank angle position control is implemented without implementing twist angle fluctuation reduction control, until stopping of the internal combustion engine has been completed.
