Stability Control of Motorcycle 2011-32-0558

We developed active control more suitable for sports riding than the previous electronic stability control system for enjoying sports riding by many users.
One of them, the traction control system S-KTRC (Sports Kawasaki TRaction Control) uses the sensor output like not only the slippage calculated from the front and rear wheel speed but also engine speed, throttle position, and gear position etc. As the result, conditions of the motorcycle and rider's intention are calculated by ‘Motorcycle model’ in the ECU continuously. By this ‘Motorcycle model’, S-KTRC confirms the real time conditions and predicts the succeeded condition, every 5milliseconds to decide to govern torque.
The ABS system KIBS (Kawasaki Intelligent anti-lock Brake System), it is possible to control the rear wheel's lift by using the pressure data of the front brake at the sudden braking operation. And by using the engine data, it is also possible to avoid the no preferable intervention by the ABS control, when the motorcycle goes into the corner under the shift down operation. Moreover, this system keeps the soft feedback feeling to rider's hand and foot by this precision ABS control.
Each control system obtained good evaluation from beginner rider to expert rider. And these systems worked very well from every road surface condition.
