Yamaha MotoGP: Nueva electrónica

[el_chorvo]

Yamaha is planning to introduce its next generation of MotoGP electronics early in the 2012 racing season.

Masahiko Nakajima, general manager of Yamaha's Motorsport Development Division, explained that the current control system fitted to the new 1000cc M1 is an extension of technology used for the previous 800cc machine.

However, the next generation of electronics are being developed in parallel.

"We have changed the electric control - especially traction control, wheelie control and also engine braking - for the 1000. But the electric control is still not the new generation," explained Nakajima, speaking during last week's Sepang test.

"The current developments are based on the same electric control strategy as last year, but parallel development of the next generation is ongoing. As soon as we reach good enough results with the next generation we will introduce it.

"I can't say exactly when, but I hope early in the season."

Yamaha has been developing this next generation, in partnership with Magneti Marelli, since last year.

Asked to explain the advantages of the new system, Nakajima explained that it would be more suited to the complexities of real world motorcycle dynamics.

"The existing generation of computer has a motorcycle 'model' inside, so the computer knows things like 'now the bike is standing up, or banking, or braking, which corner'. This is normal. Our competitors' control systems also work like this," he began.

"For the next generation we need a more precise motorcycle model inside the computer and also how to actuate the engine or chassis more effectively. You have to reconsider these areas to make another step."

Another crucial factor will be to create a more intuitive relationship between rider and electronics.

"If a rider can believe in the bike, they can go faster," said Nakajima. "For example, the present traction control or wheelie control is sometimes disturbing the rider's control.

"They want to accelerate, but when the tyre starts to spin sometimes the ECU responds at the wrong moment, or in the wrong way. The timing and 'philosophy' of the control is very important. It is a very critical area."

A more tangible goal will be to improve acceleration, which Nakajima named as Yamaha's main focus for the 2012 M1.

"After last year we made acceleration performance our top priority - chassis wise, engine wise and electronics wise," said Nakajima, whose riders were often outgunned in a straight line during 2011.

In pursuit of that goal, and in addition to the changes made for the present electronics, Yamaha has "changed the chassis rigidity. It looks not so different from the outside, but it is quite different in terms of the balance of the rigidity."

The 1000cc engine also has “torque delivery characteristics specifically to help acceleration performance and make it more rider-friendly."

Nakajima feels the new M1 - in the hands of factory riders Jorge Lorenzo and Ben Spies - is currently lacking two or three tenths of consistent pace relative to Honda's reigning world champion Casey Stoner, fastest in both pre-season tests so far.

But Yamaha will not introduce any major new parts during the third and final official pre-season test, at Jerez from March 23-25, which will instead be dedicated to machine set-up for the opening round.

"In Jerez we have to concentrate on the opening race. So we won't change too much," he said. “We have been testing many items at Sepang, but at Jerez we have to concentrate on which direction to go, so the riders are not confused for the first race. We have to choose one spec, or a maximum of two, for Jerez."

Following Jerez, the first race of the 2012 season will take place at Qatar on the evening of April 8.

Esperemos que esa nueva electrónica menos "torpe" y que deje algo más en las manos de los pilotos

Interesante tema. Lo comentan también en el Solo Moto de esta semana pero dicen que al menos no la introducirán hasta media temporada, más o menos.

V's.

Por lo que he entendido, quieren hacer un CT que actúe solo cuando el piloto quiere, no? Eso me parece muy complicado, ya que el piloto no tiene tiempo de decirle a la moto que esta vez en concreto quiere que la moto derrape y no entre el CT.

Un poco ciencia ficción me parece, a no ser que el piloto pudiese comunicarse por telepatía con la moto  En cualquier caso, veremos como avanza el tema, si lo consiguen puede ser muy pero que muy interesante...

En el sistema Aprilia (de calle), cuando ya estas derrapando, el mando del gas deja de actuar sobre el acelerador, y pasa a gestionar el derrapaje, a mas gas, mas derrapaje, menos gas, menos derrapaje..... se que parece "lo mismo" pero no lo es, ya que la centralita se centra e el deslizamiento de la rueda trasera para decidir cuando se acelera..... que nos se podra hacer en motogp.

La gestion electronica puede perfectamente discernir si el derrapaje es provocado o si es imprevisto, no hace mucho venia un articulo en Formula moto sobre gestion electrinica, y en una Bmw muleto, la centralita indicaba la temperatura de los neumaticos..... lo que no es nada especial, salvo por que no usaban medidores de temperatura, simplemente el software dedudia la temperatura en base a los datos de otros senores (gps, inclinometro...).... no que no podran hacer en motogp

Entonces carakol, ¿la moto sabe distinguir entre un "latigazo" y una derrapada prolongada? Qué cosas madre...

No creo que sea "raro", pienso que la electronica podria distinguir cuando el piloto "quiere" hacer una derrapada (velocidad de actuacion de los mandos, por ejemplo)

O a lo mejor mide el desplazamiento lateral y la velocidad del mismo, y si detecta que es brusco lo corta, mientras que si nota que es una derrapada suave y fluida, la deja seguir.

Meras hipotesis todo, que yo ni p*ta idea del tema.
