[kropotkin thinks...] - Will Cheats Prosper? How Inertial Platforms Can Manipulate Th
If you enjoyed reading this article, please click here to view it on Kropotkin's site, MotoGP Matters.
----------------- The move to a standard electronics package, both hardware and software, had raised the hopes of fans, teams and organizers that a more level playing field could be established, and costs cut. The ideal sketched by Dorna and IRTA when the plan first came out has proven to be impossible to achieve. The manufacturers have resisted calls for a completely spec hardware and software package, and so a compromise has been reached. The ECU hardware and software will be built, updated and managed by official electronics supplier to MotoGP, Magneti Marelli. Factories will be free to choose their own sensors, but those sensors will have to be homologated, and made available to any other manufacturer which wishes to use it at a reasonable price. Not quite all of the sensors, however. In response to a request by the factories, the inertial platform will remain what is called a free device, i.e. any manufacturer can choose to use whichever inertial platform they like, without first submitting it for a approval to Dorna, or making it available to their rivals at a price. The inertial platform is a crucial part of the electronics package, consisting of a collection of gyroscopes and accelerometers, which describe the attitude and motion of the bike. In other words, the inertial platform tells the ECU what lean angle the bike is at, whether it is braking or accelerating, how hard it is corner, etc. Giving manufacturers the freedom to use their own inertial platforms has created a lot of suspicion. Because the inertial platform plays such a pivotal role, there have been accusations that some manufacturers, especially Honda and Yamaha, wish to use their proprietary units to circumvent the rules. There are good reasons to build some intelligence into inertial platforms, as such intelligence can increase accuracy, and therefore help the ECU software perform better. This is the reason the factories give for wanting their own inertial platform; experience with the spec unit used by the Open class machines has shown it to be insufficiently accurate. But the intelligence built in to the inertial platform could go well beyond just improving accuracy. By including a powerful processor in the inertial platform, one which could be programmed by a manufacturer with their own software, and their own algorithms and strategies, the inertial platform could hypothetically be used to modify the strategies being used by the unified software in the spec ECU. read more
