STABILITY CONTROL SYSTEM, SADDLED VEHICLE HAVING STABILITY CONTROL SYSTEM, METHOD, AND COMPUTER PROGRAM

摘要

The stability control system includes: a wheel rotation speed sensor configured to acquire a wheel rotation speed, the wheel rotation speed being a rotation speed of the first wheel; a vehicle speed sensor configured to acquire a vehicle speed of the vehicle; an attitude detection unit configured to acquire a bank angle of a vehicle body; and an arithmetic unit configured to, based on the wheel rotation speed and the vehicle speed under a predetermined travel condition, calculate a value representing a relationship between the wheel speed of the first wheel and the wheel speed of the second wheel as a tire radius correction value for each different bank angle, and calculate a control-purpose wheel speed by correcting the wheel rotation speed based on a tire radius correction value corresponding to a current bank angle. The braking force or driving force of the vehicle is changed by using the control-purpose wheel speed.
