Find out how your system works with the 3D – Intelligence technology.
GRIPONE include several control strategies. All of them are connected to the 3D-INTELLIGENCE control system, but each strategy works following a specific algorithm.
If you want to describe the anti wheelie control strategy in few words, you can say that the user fix a target value of wheelie. When the wheelie of front tyre is greater than this value, the strategy start to reduce the power. When the wheelie of front tyre come back to normal (under the value) the strategy stop to reduce the power.
Itself the strategy of anti wheelie looks quite simple but the reality is a bit different because it is quite difficult estimate the level of wheelie. GRIPONE together with 3D-INTELLIGENCE estimate a vehicle real speed. This speed is not the speed of front wheel ( because it drops during the wheelie) and it is not the speed from the rear wheel (because it is more then real speed because of the spinning). Starting from the vehicle speed, rear speed and front speed, the anti wheelie strategy calculate the level of wheelie. When the level of wheelie is greater than the target value, the strategy start to reduce the power. When the level of wheelie is under the target value, the strategy stop to reduce the power.
The real vehicle speed is one of the most complex calculation into the GRIPONE strategies. A very accurate value come from the correct initialization of inertial platform. Without the inertial platform IMU the estimation of real vehicle speed could be not that good (even if the system can work nicely even without IMU).
