A motor control device controls a fan motor, and controls a motor speed so as to maintain a predetermined airflow value. For this, the motor control device includes an input terminal for inputting a first operation parameter indicating the motor speed or a second operation parameter indicating a motor torque. Moreover, the motor control device includes a motor-speed target value arithmetically-operating unit that calculates, using a predetermined airflow value and the motor torque, a necessary modified value for the motor speed at the predetermined time intervals. Further, the motor control device includes an output terminal that outputs an instruction speed of the motor based on the necessary modified value.

An object to save power and control engine startup and shutdown while improving the cabin environment with a simple configuration. A vehicular air-conditioning control device detects an outside air temperature; finds from an eco-running map a time TA until odor and so forth corresponding to the outside air temperature arises, an eco-runnable TB extended by shutting down a blower, and a time TC at which to shut down the operation of the blower fan; shuts down the blower fan at the time TC during eco-running; and, when the eco-runnable time TB elapses, causes the blower fan to operate, issues an engine startup request, and initiates refrigerant circulation by a compressor. Thus, by operating the blower fan for a predetermined time when the engine has been shut down by eco-running, the comfort of the cabin environment can be improved and the eco-runnable time can be extended to save power.

摘要:
There is disclosed a device which realizes a shortcut function without providing any key exclusively used for the shortcut function. When a home key is operated in a state where a lower screen at a lower position of a hierarchical structure is displayed, a home screen at an upper position of the hierarchical structure is displayed, and data to specify the lower screen when the home key is operated are stored in association with the home key. When the home key is operated in a state where the home screen is displayed, the lower screen is displayed based on the stored data to take a shortcut to the lower screen from the home screen.
