Two-wheeled motor vehicle and control device therefor
First Claim
1. A control device for a two-wheeled motor vehicle, in which a curvature radius of a cross-section of a tire mounted on one of a front wheel and a rear wheel is larger than a curvature radius of a cross-section of a tire mounted on the other of the front wheel and the rear wheel, the control device comprising:
- a sensor arranged to detect a rotation speed of the one of the front wheel and the rear wheel;
a sensor arranged to detect a rotation speed of the other of the front wheel and the rear wheel; and
a turn determining processor programmed to determine that the vehicle is turning based on a condition that a value corresponding to a bank angle of the vehicle is higher than a threshold;
whereina value corresponding to the bank angle of the vehicle is defined as a value indicating a relative amount of the rotation speed of the one of the front wheel and the rear wheel relative to the rotation speed of the other of the front wheel and the rear wheel;
the turn determining processor compares the rotation speed of the one of the front wheel and the rear wheel and the rotation speed of the other of the front wheel and the rear wheel, while utilizing a coefficient corresponding to a difference in a diameter between the tire of the one of the front wheel and the rear wheel and the tire of the other of the front wheel and the rear wheel; and
the control device includes a coefficient updating processor that is programmed to determine whether or not the diameter of the tire of the one of the front wheel and the rear wheel or the diameter of the tire of the other of the front wheel and the rear wheel is changed based on the rotation speed of the one of the front wheel and the rear wheel and the rotation of the other of the front wheel and the rear wheel, and then to update the coefficient when it is determined that the diameter has changed.

Abstract
A two-wheeled motor vehicle includes a control device and is configured such that a radius of curvature of a cross-section of a tire mounted on one of the front wheel and the rear wheel is larger than a radius of curvature of a cross-section of a tire mounted on the other wheel. The control device includes a sensor arranged to detect a rotation speed of the one wheel, a sensor arranged to detect a rotation speed of the other wheel, and a turn determining section programmed to determine that the vehicle is turning based on a condition that a value corresponding to a bank angle of the vehicle is higher than a threshold. The value corresponding to the bank angle of the vehicle is a value indicating the relative amount of the rotation speed of the one wheel relative to the rotation speed of the other wheel.
