摘要： A display method for a hybrid vehicle includes displaying an engine icon representing the engine, a battery icon representing the battery, and a flow icon representing an energy flow between the engine icon and the battery icon on a display unit in accordance with a driving state of the hybrid vehicle. The display method includes displaying the flow icon in a display mode indicating that there is the energy flow between the engine and the battery when the battery is charged. The display method includes displaying the engine icon in a first display mode when the engine is stopped, displaying the engine icon in a second display mode when the engine is operated at engine rotation speed equal to or lower than reference rotation speed, and displaying the engine icon in a third display mode when the engine rotation speed is higher than the reference rotation speed.

摘要： A method for controlling a hybrid vehicle includes an engine, a battery charged with electric power generated by the engine, and a motor as a drive source and having multiple running modes that can be selected through a mode operation. As the running mode, the method for controlling a hybrid vehicle includes a normal mode configured to perform charging of the battery according to a running state; and a charge mode configured to electric power generation by the engine according to a mode operation, the method comprising setting an upper limit of charging electric power based on the generated electric power in the charge mode to be lower than an upper limit of charging electric power based on the generated electric power in the normal mode.

摘要： A catalyst warm-up control method for a hybrid vehicle supplies electric power to an electric motor by a battery, to charge the battery by a power generation engine, and to treat exhaust gas from the engine with a catalyst, the hybrid vehicle selecting a manner mode in which power generation using the engine is stopped. The catalyst warm-up control method performs catalyst warm-up control such that when the temperature of the catalyst becomes lower than a normal threshold temperature for activating the catalyst, the target rotation speed of the engine is controlled to a first warm-up required rotation speed at which the catalyst can be heated to a temperature that is higher than the normal threshold temperature. When the manner mode is selected, control is performed when temperature of the catalyst becomes lower than a manner mode threshold temperature that is equal to or less than the normal threshold temperature.

摘要： A control method for a hybrid vehicle including a generator and an electric motor, the generator being configured to charge a battery by use of power of an engine, the electric motor being configured to drive driving wheels by electric power of the battery, is provided, is provided. The control method having controlling the generator and the electric motor and accepting mode setting to set any of a normal mode, a regeneration driving mode, and a silent mode, the regeneration driving mode being a mode in which a regenerative braking force caused by the electric motor is larger than that in the normal mode, the silent mode being a mode in which charging by the engine is inhibited, wherein: when the normal mode is set, setting of the silent mode is not accepted; and when the regeneration driving mode is set, setting of the silent mode is accepted.
