Yep, systems like that were widely used during 2002/2003. This was banned.PNSD wrote:It was during the 2002/2003 season I heard. This isn't new technology.
Yep..And BTW..I thought the top teams had a modern variation on the old pre-selector gearbox, where it was in two gears at once and it only shifted upon dipping the clutch.?Ralf Schumacher would obviously approach in 7th, somewhere along the straight he would downshift 5 gears to take the corner in 2nd, however the downshifts wouldn't occur until the braking point.
At least I think thats how it worked.
Hi Brian, have you any more info on this? A link to a story or an extract of the regs?hardingfv32 wrote:They are adding restrictions
Scarbs did describe modern F1 gearbox as not being pre-select, but just very precise and fast ordinary system.strad wrote:Yep..And BTW..I thought the top teams had a modern variation on the old pre-selector gearbox, where it was in two gears at once and it only shifted upon dipping the clutch.?
The whole text is new to the regulations but one can safely assume that most of it is covered by piror FiA technical directives that have been in place for some time. The difference is that they are now included in the regulations. They probably do this when the wording has proved to be effective and unambiguous.9.8 Gear changing:
9.8.1 Automatic gear changes are considered a driver aid and are therefore not permitted. For the purposes of gear changing, the clutch and throttle need not be under the control of the driver.
9.8.2 Gear changing is restricted during the following periods :
‐ Race start: one gear change is permitted after the race has started and before the car speed has reached 100kph, provided every gear fitted to the car is capable of achieving at least 100km/h at 18,000rpm.
‐ Pit stops: No gear change is permitted after a pit stop and until the car speed gets within 10km/h of the pit lane speed limit when leaving the pits.
9.8.3 The minimum possible gear the driver is able to select must remain fixed whilst the car is moving. Each individual gear change must be separately initiated by the driver and, within the mechanical constraints of the gearbox; the requested gear must be engaged immediately unless over‐rev protection is used to reject the gear shift request. Once a gear change request has been accepted no further requests may be accepted until the first gear change has been completed.
Multiple gear changes may only be made under Article 5.19 or when a shift to gearbox neutral is made following a request from the driver.
If an over‐rev protection strategy is used this may only prevent engagement of the target gear, it must not induce a delay greater than 50ms. If a gear change is refused in this way, engagement may only follow a new and separate request made by the driver. Any de‐bounce time used to condition driver gear change requests must be fixed.
9.8.4 The maximum permitted duration for down changes and up changes is 300ms and 200ms respectively. The maximum permitted delay for the latter is 80ms from the time of the driverrequest to the original gear being disengaged.
The duration of a gear change is defined as the time from the request being made to the point at which all gear change processes are terminated. If for any reason the gear change cannot be completed in that time the car must be left in neutral or the original gear.
9.8.5 Distance channel or track position is not considered an acceptable input to gearbox control.
So as I understand it they can shift to second gear before reaching 100 km/h‐ Race start: one gear change is permitted after the race has started and before the car speed has reached 100kph, provided every gear fitted to the car is capable of achieving at least 100km/h at 18,000rpm.
I was taking these rule changes as flags for some creative active by the teams over the last year. You are proposing that this might not be the case in all instances?WhiteBlue wrote:The whole text is new to the regulations but one can safely assume that most of it is covered by piror FiA technical directives that have been in place for some time.
