  • Patent number: 9919731
    Abstract: A vehicle includes a body frame, an engine, a transmission, an injector, an engine controller, and a transmission controller. The body frame supports three or more wheels. The engine is attached to the body frame. The transmission is attached to the body frame and changes a torque from the engine and outputs a resulting torque. The injector is disposed on or above the engine, and supplies fuel to the engine. The transmission controller is configured or programmed to control a gear position of the transmission. The engine controller and the transmission controller are spaced apart from each other.
