TWO-WHEELED VEHICLE OVERTURN PREVENTION METHOD AND DEVICE
First Claim
1. A two-wheeled vehicle overturn prevention method, comprisingpresetting maximum allowable lean angles corresponding to vehicle body velocities in relation to lean angles of a vehicle body,estimating an estimated lean angle, which is a lean angle of the vehicle body after a predetermined amount of time, on the basis of a temporal change in an actual lean angle of the vehicle body,estimating an estimated vehicle body velocity, which is a vehicle body velocity of the vehicle body after the predetermined amount of time, on the basis of a temporal change in an actual vehicle body velocity of the vehicle body, andin a case where the estimated lean angle exceeds or looks to exceed a maximum allowable lean angle corresponding to the estimated vehicle body velocity, adapting the two-wheeled vehicle overturn prevention method to accelerate the vehicle body or keep the vehicle body from decelerating.

Abstract
There is provided a two-wheeled vehicle overturn prevention method, wherein maximum allowable lean angles corresponding to vehicle body velocities are preset in relation to lean angles of a vehicle body, and in a case where an actual lean angle of the vehicle body exceeds a maximum allowable lean angle corresponding to an actual vehicle body velocity of the vehicle body or in a case where an estimated lean angle of the vehicle body after a predetermined amount of time exceeds or looks to exceed a maximum allowable lean angle corresponding to an estimated vehicle body velocity, the two-wheeled vehicle overturn prevention method is adapted to accelerate the vehicle body or keep the vehicle body from decelerating.

9. A two-wheeled vehicle overturn prevention device comprising:
-
a vehicle velocity sensor that detects a vehicle body velocity; a lean angle sensor for detecting a lean angle of a vehicle body; lean angle calculating means that calculates a lean angle of the vehicle body on the basis of an output value of the lean angle sensor; instability judging means that judges traveling instability of the vehicle body on the basis of the vehicle body velocity and the lean angle; drive addition quantity calculating means that calculates an engine drive addition quantity in a case where it has been judged by the instability judging means that the vehicle body is unstable; and drive force increase instructing means that outputs a drive addition quantity to an engine ECU. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
