Rider characteristic determining apparatus, and a saddle riding type vehicle having the same

A rider characteristic determining apparatus for determining control characteristics of a rider controlling a saddle riding type vehicle, the rider characteristic determining apparatus comprising:

• a first vehicle state detector that detects at least one of a yaw rate and a yaw angle of the saddle riding type vehicle;
• a turning movement discriminating unit that discriminates a section where the saddle riding type vehicle has made a turning movement;
• a second vehicle state detector that detects at least one of a roll rate, a roll angle, a pitch rate, a pitch angle, and a caster angle of the saddle riding type vehicle;
• a component separating unit that separates detection values detected by the first vehicle state detector and the second vehicle state detector in the turning movement section discriminated by the turning movement discriminating unit, into adjustment components that are high-frequency band components higher than a threshold frequency set beforehand, and prediction components that are low-frequency band components lower than the threshold frequency;
• a vehicle stability characteristic determining unit that determines a vehicle stability characteristic of the saddle riding type vehicle;
• and
• a turning characteristic determining unit that determines a turning characteristic of the saddle riding type vehicle;
• wherein
• the vehicle stability characteristic determining unit includes a vehicle stability score calculating unit that calculates a vehicle stability score of the saddle riding type vehicle based on a ratio between the adjustment components and the prediction components separated from the detection value of the first vehicle state detector by the component separating unit;
• and
• the turning characteristic determining unit includes a turning performance score calculating unit that calculates a turning performance score of the saddle riding type vehicle based on the prediction components separated from the detection value of the second vehicle state detector by the component separating unit.
