Launch Control

from Wikipedia, the free encyclopedia

The launch control is a form of traction control ( "traction control"), which serves to accelerate a vehicle as quickly as possible by a technically optimized boot process. For this purpose, the clutch and gearshift are controlled in such a way that when the vehicle starts moving, the wheel speed that best accelerates the vehicle from a standstill with the optimum degree of slip is applied. Depending on the programming, the gearbox or the automatic gearshift only shifts to the next gear at the optimum speed until the design-related maximum speed or another parameter is reached. The Launch Control is therefore particularly suitable for drag races and other racing competitions. Disadvantages are the high load on the engine and the drive (in particular overheating of the clutch, which is why this function is only possible at BMW up to a certain clutch temperature) and the high fuel consumption, which results from the high speed.

The system became known through its use in Formula 1 racing cars. It was first approved by the FIA in the 2001 season and banned again from the 2003 British Grand Prix . At the World Rally Championship it was also used in World Rally Cars (class A8). It is no longer permitted since the 2011 season regulations . In 2019 there will be launch control in the racing motorcycles of the MotoGP class. Several production motorcycles with road approval , for example the Aprilia RSV4 , BMW s1000rr or the Yamaha r1 from 2015 onwards have this driver assistance system.
