Abstract: A series hybrid vehicle control method controls a series hybrid vehicle including a power generation system that generates electric power by driving an electric generator with an internal combustion engine. A control unit is configured to, in a case where a failure occurs in the power generation system, limit a torque of the internal combustion engine, set an engine rotation speed at which power generation efficiency of the electric generator is maximized within a range in which the torque is limited, and control the internal combustion engine based on the engine rotation speed.

Abstract: An Fr turn lamp that is a vehicle lamp includes a first light guide and a second light guide. The first light guide is disposed in front of a light source in the direction of an optical axis. The second light guide has a connection end connected to a vehicle width direction outer side surface of the first light guide and extends outward in the vehicle width direction from the connection end. The first light guide has a reflecting surface configured to reflect a part of incident light from the light source toward the connection end of the second light guide.
