  • Publication number: 20240013324
    Abstract: When an operation for reserving a rental car is performed on a communication terminal, reservation information is transmitted from the communication terminal to the management server. The management server extracts a reservation period included in the reservation information, issues an incentive based on the reservation period, and notifies the incentive. When the user applies an incentive to the communication device to confirm the reservation, the operation information is sent to the management server, and the management server confirms the reservation. When the reservation confirmation is notified, the communication terminal sets the reservation period as VPP participation period of the electrified vehicles, and transmits the participation information including the information of VPP participation period to HEMS controllers. HEMS controllers register the electrified vehicles as power resources in the period specified by VPP participation period.

  • Patent number: 7971668
    Abstract: In a hybrid vehicle 20, when a deceleration demand based on accelerator-off is made in selecting an S position that allows arbitrary selection of shift positions SP1 to SP6, and fuel cut cannot be prohibited from a state of a battery 50, an engine 22 and motors MG1 and MG2 are controlled so that a driving force based on a torque demand Tr* is outputted with the fuel cut (Steps S410, S420, S360 to S400). When the deceleration demand based on the accelerator-off is made in selecting the S position, and the fuel cut can be prohibited from the state of the battery 50, the engine 22 and the motors MG1 and MG2 are controlled so that the engine 22 substantially performs self-sustaining operation at a target rotation speed Ne0 and a driving force based on the torque demand Tr* is outputted (Steps S340 to S400).

  • Patent number: 7814743
    Abstract: In an engine 5 including an in-cylinder injector, the valve timing of an intake valve is retarded by VVT (Variable Valve Timing) controlled by an engine ECU to decompress in a combustion chamber at engine startup. In accordance with a configuration in which the valve timing of intake valve is advanced in a stepped manner from an initial set value, fuel injection from in-cylinder injector is inhibited during the time when the advance is equal to or below a predetermined standard value, and fuel injection from in-cylinder injector is allowed when exceeding the predetermined standard value, whereby degradation in the exhaust emission level in accordance with start time decompression control can be suppressed.

  • Patent number: 7610954
    Abstract: The technique of the invention determines whether input data for driving and controlling a cooling fan have any abnormality (steps S100 and S110), sets an actual drive level F* of the cooling fan to a high level (Hi) in the event of detection of any abnormality (step S130), and controls a fan motor to drive the cooling fan at the set drive level F* (step S140). This arrangement effectively prevents a temperature rise to an abnormally high level in any of an engine and motors even in the event of any abnormality arising in the input data.
