VEHICLE SPEED DETERMINATION SYSTEM, STABILITY CONTROL SYSTEM, AND SADDLE-RIDING TYPE VEHICLE HAVING STABILITY CONTROL SYSTEM

摘要

PROBLEM TO BE SOLVED: To determine a vehicle speed when turning by a steering operation.;SOLUTION: A vehicle speed determination system is for a vehicle having a front wheel and a rear wheel. The vehicle speed determination system includes a wheel speed sensor 35 detecting a wheel speed V_f of a front wheel, and a computing unit 200 which determines a vehicle speed V(r) at a rear wheel ground point on the basis of a difference between the vehicle speeds generating between a front wheel ground point and the rear wheel ground point due to a difference between a running trace of the front wheel and a running trace of the rear wheel, and on the basis of the wheel speed V_f of the front wheel.;COPYRIGHT: (C)2015,JPO&INPIT
