  • Publication number: 20240092339
    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.

  • Patent number: 11192539
    Abstract: A vehicle control method for executing a sailing stop control when a drive source stop condition is established while a vehicle is traveling. The sailing stop control stops a drive source of the vehicle and releases an engaging element provided between the drive source and a drive wheel such that the vehicle travels under inertia. The vehicle control method acquires information on a road on which the vehicle will travel, and then determines whether there is a section on a route where the sailing stop control can be executed based on the information. Upon determining a section exist capable of the sailing stop control, the vehicle control method estimates a power shortage amount, which is a shortage amount of power during sailing stop control, based on the information, and charges a battery with power required to cover the power shortage amount prior to starting the sailing stop control.
