Electronic throttle control and cruise control for handle bar type vehicle

A saddle type vehicle comprising an engine and a steering handle bar, the steering handle bar comprising:

• a bar shape;
• a throttle grip mounted to an end of the steering handle bar so as to be capable of turning relative to the steering handle bar;
• and
• a grip-driving electric motor disposed on the steering handle bar so as to be interlocked with and connected to the throttle grip,
• the engine comprising:
• an air intake path forming body that forms an air intake path;
• a valve shaft rotatably supported on the air intake path forming body;
• a butterfly-shaped throttle valve secured to the valve shaft, the valve controlling the size of the opening of the air intake path;
• and
• an actuator connected to an end of the valve shaft, the actuator comprising a valve shaft-driving electric motor which is moved in response to the turning operation of the throttle grip, the actuator being connected to an end of the valve shaft so as to rotate the valve shaft, and so that the rotational movement of the valve shaft is fed back to the throttle grip,
• wherein the grip-driving electric motor is moved by the amount of movement according to the amount of rotation of the valve shaft in response to the operation of the actuator.
