Posture control device of motorcycle and motorcycle

A motorcycle, comprising:

• a steering unit;
• a posture control system, said posture control system comprising
• a vehicle speed sensor configured to detect a vehicle speed of the motorcycle,
• a displacement detection sensor configured to detect displacement of the motorcycle in a yaw direction and displacement of the motorcycle in a roll direction, and to output a yaw direction output and a roll direction output,
• an adjustment part configured to output a synthesized output by adjusting the yaw direction output and the roll direction output of the displacement detection sensor corresponding to the detected vehicle speed, and
• a first actuator configured to control the posture of the motorcycle based on the synthesized output, wherein
• the adjustment part is also configured to output the synthesized output in which the yaw direction output is larger than the roll direction output with respect to the yaw direction output and the roll direction output when the vehicle speed is low, and the adjustment part (302) outputs the synthesized output in which the roll direction output is larger than the yaw direction output with respect to the yaw direction output and the roll direction output when the vehicle speed is high, and wherein the posture control system thereby controls the posture of the motorcycle by detecting the posture and by controlling the steering unit based upon a detection result.

A posture control system of a motorcycle, said posture control system comprising:

• vehicle speed sensor means for detecting a vehicle speed of the motorcycle;
• displacement detection means for detecting a displacement of the motorcycle in a yaw direction and displacement of the motorcycle in a roll direction, and for outputting a yaw direction output and a roll direction output;
• adjustment means for outputting a synthesized output by adjusting the yaw direction output and the roll direction output of the displacement detection sensor means corresponding to the detected vehicle speed;
• and
• first actuator means for controlling the posture of the motorcycle based on the synthesized output, wherein
• the adjustment means is also for outputting the synthesized output in which the yaw direction output is larger than the roll direction output with respect to the yaw direction output and the roll direction output when the vehicle speed is low, and for outputting the synthesized output in which the roll direction output is larger than the yaw direction output with respect to the yaw direction output and the roll direction output when the vehicle speed is high, and wherein the posture control system thereby controls the posture of the motorcycle by detecting the posture and by controlling the steering unit based on a detection result.
