Abstract
A catalyst degradation determining device for a straddled vehicle that includes an engine, a catalyst for cleaning an exhaust gas from the engine, and a throttle valve that is controllable by cruise control of the straddled vehicle to keep a traveling speed of the straddled vehicle constant. The catalyst degradation determining device includes a determiner that determines whether the cruise control is being executed, and an execution controller. The execution controller is configured to determine a degradation state of the catalyst while controlling an air-fuel mixture supplied through the throttle valve to the engine, in a case where the determiner determines that the cruise control is not being executed, and at least one running state of the straddled vehicle satisfies at least one predetermined allowable condition, and not to determine the degradation state of the catalyst in a case where the determiner determines that the cruise control is being executed.
