  • Patent number: 10344854
    Abstract: An engine room temperature rise restricting apparatus including an open and close detector of the grille shutter, and a controller including a CPU and a memory coupled to the CPU, wherein the CPU and the memory are configured to perform: detecting a stuck-closed failure of a grille shutter of a condition that the grille shutter remains closed regardless of an open instruction for the grille shutter, based on signal from the open and close detector; and controlling a speed ratio of a continuously variable transmission so that an upper limit of an engine rotational speed or an engine driving force when the stuck-closed failure is detected is smaller than an upper limit of the engine rotational speed or the engine driving force when the stuck-closed failure is not detected.

  • Patent number: 8594877
    Abstract: A control apparatus for a hybrid vehicle includes an internal combustion engine and a generator motor, a capacitor, and a driving force assisting unit. Further, the control device includes a switching unit that selects an appropriate traveling range from a plurality of traveling ranges including at least a normal traveling range and a charging priority range for preferentially charging the capacitor and switches the range, and a threshold value increasing unit that increases, when the charging priority range is selected by the switching unit, the predetermined determination threshold value as compared to when the normal traveling range is selected by the switching unit.
