  • Publication number: 20240317209
    Abstract: A hybrid vehicle us equipped with a power generation first motor generator driven by an internal combustion engine, and a second motor generator driven by a battery. The hybrid vehicle includes an S mode, an ECO mode and a NORMAL mode which are basic travel modes. A mode change switch is used to switch between the modes. In the S mode and the ECO mode, a deceleration rate of regenerative braking on downhill roads is large, and an amount of regeneration is large. When a downhill road on a travel route has been predicted, in the S mode and the ECO mode, a controller executes an SOC reduction control in which an SOC is reduced in advance before a downhill road starts, and in the NORMAL mode, the controller does not execute the SOC reduction control.

  • Patent number: 12024156
    Abstract: A method for controlling a hybrid vehicle executes control in which a state of charge of the battery at a time point at which the hybrid vehicle reaches a destination is lower than an upper limit state of charge by executing an EV mode until the hybrid vehicle reaches the destination. During execution of the control, if an estimated value of a lowest temperature of an engine coolant until the hybrid vehicle reaches the destination is equal to or higher than a first threshold value, the EV mode is started when the EV mode is continuable to the destination, and if the estimated value of the lowest temperature is lower than the first threshold value, a section for executing the EV mode is shortened compared to when the estimated value of the lowest temperature is equal to or higher than the first threshold value.
