Engine Rev Changes - KERS?

[DaveKillens]

I just do not see how KERS can be practical when the engine is near peak RPM. KERS does not posess enough power to drag the engine past it's limited RPM.
It's present application is for acceleration, getting a good launch out of corners. Not at the end of a straight.

This is intriguing. If I understand you, you are saying that KERS can increase acceleration (say 100 - 140 MPH time), but not absolute top speed?

We all know that the mathematically calculated speed a car could achieve -- with, for example a 1:1 (!) final drive -- is not possible in the real world. I suppose KERS could increase a car's top speed if the gearbox had a gear to be used only with KERS. Without KERS, the engine would not have enough power to take advantage of this "high speed" gear, but could gain an advantage by using KERS in conjunction with that gear. I am probably not stating this with technical rectitude, but I'm counting on the intelligence of our posters to educate me on this point. . . .

My apologies on a tardy reply.
I was assuming that the gearing would be set in the traditional manner, where the car reaches peak velocity at the same time it reaches peak RPM.

During the first practice/qualifying/race this season, one of the announcers made a point to explain that phenomenon as the KERS charging up. I remember him saying that. And I think it was Matchett.

In light of all of the research, that may be a questionable explanation...

Yes he is wrong.

It is not KERS, or anything based in reality. It is all in the digital realm of networking, buffering, timecode, wifi range.

The car moves from hotspot to hotspot as it moves around the track, and as it enters each new hotspot (like a few meters past the start/finish line at the Spanish GP), there is a quick digital video glitch (A few green 'blocks') that lasts a couple of frames, that comes immediately after the sound glitch. The sound and video need to sync back up as it goes from cell to cell as Brundle had said in the feed.

I grabbed this problkem by the cajones and analyzed the glitches from a few races and I can say with certainty this:

- The glitch is unrelated to KERS
- The glitch is unrelated to anything that is not the broadcasting equipment
- The glitch is in the broadcasting equipment, and is digital in nature.

Since all digital video transmitted wirelessly (except for high end applications I may be unaware of) has some form of compression, this all makes perfect sense. The glitch happens on straights, at the end of braking zones, and half through corners. But it is always at the same spot, even in different cars, and the cars speed is not affected by it.

How do we e-mail Matchett and ol' whatshisname (the ex F1 driver announcer)? They should re-address this issue during broadcast...

[Giblet]

I use outlook and web mail

Been searching the SpeedTV web site for 10 minutes and I can't find a contact for the F1 broadcast, or either of three commentators specifically.

It probably has to do with the very busy message boards on the site, that would keep them from being able to have their emails published.

I think you need to get an account on their forum and post there, but I may be wrong. I am quite talented in all things computer, and have had no success finding anyone@speedtv.com.

This sound thing is really annoying me! As has been said, it's definitely not KERS since it affects non-KERS cars.

One of the commentators said during the Turkish practice/qualifying/race (can't remember which) that it was when they switch to a differenct sound cell. I couldn't figure out what this meant at the time, but after reading this thread I agree with whoever said it was related to switching transponders.

[Giblet]

During qualification, I noticed the video glitch, the green blocks, during a period where the car was very low on revs, so the audio glitch was not very noticeable, but it was existent.

When the motor is at full song, the change in pitch is very obvious.

MAtchett is an idiot stuck in the 1990's

Hamilton wasn't using the KERS system today and I've noticed the sound glitch when they showed him on-board. One was at the start-finish line and another was when he went under that little bridge at the end of the Hangar straight.

Every car, at the same place on track, every lap.

Transponder range.

Scroll up.

It has nothing to do with the cars themselves, it's all to do with the live broadcasting equipment.

in the world of F1, I am simply astounded that they do not use "motes" for data acquisition and transmission...
