How it works: Launch Control Strategy

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 launch control strategy in few words, you can say that the user fix a target value of wheelie (during the launch). When the wheelie of front tyre is bigger 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.

The strategy of launch is the simplest one but the calculation of real vehicle speed is the most complex because when the speed of bike is close to zero (0) the difference between front speed and rear speed could be big (and this make the algorithm very unstable). The real vehicle speed is used to estimate the wheelie level like in the wheelie control strategy. When the level of wheelie is over 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).
