Sequential M gearbox with Drivelogic*

The concept

The sequential M gearbox with

Drivelogic is an automated manual

gearbox with which clutching and shift-

ing is assumed by an electro-hydraulic

system.

The SMG Drivelogic is operated via two

shift paddles on the steering wheel and

the selector lever in the center console.

It offers the following functions:

> Sequential and automated shifting

mode

> Ability to choose between different

driving programs – Drivelogic

> Gradient assistance, refer to page 73

> Upshift display and shift lights, refer

to page 74

> RPM matching on downshifts

> Driving dependent functions:

The respective driving situation, e.g.

cornering, mountain driving or brak-

ing, is detected by sensors and taken

into account for shifting, e.g. to

achieve optimum gear selection dur-

ing deceleration and subsequent

acceleration

> Slip recognition at the rear axle for

increasing driving stability, e.g. dur-

ing downshifting on slippery road

surfaces

> Operating safety through protection

against misshifting.

Under normal operating conditions, fuel

consumption is lowest when driving in

the first driving program of the auto-

mated shifting mode.

Selector lever positions
