Munich. With the new Automated Shift Assistant (ASA),
BMW Motorrad presents an innovative technical solution that makes
riding simpler and more comfortable. True to the motto "Simplify
your ride", the riding experience is further enhanced by the
automation of the clutch and gearshifting, without sacrificing the
emotionally important dynamics of shifting.
The Automated Shift Assistant features a clever functional
design in which two electromechanical actuators automate the clutch
and gearshift of the six-speed transmission, which is the main
difference to a conventional shift assistant. There is no need for a
hand lever to operate the clutch manually. Starting, stopping and
manoeuvring are made easy with the Automated Shift Assistant.
Riding with the Automated Shift Assistant also becomes more
enjoyable thanks to fast, rev- and load-adapted shift sequences and
the resulting precise gear changes. The rider's workload is reduced,
which makes riding even more enjoyable. In addition, the Automated
Shift Assistant creates an even more direct connection with the
powerful boxer engine, as the precise clutch actuation makes it even
easier to control the riding experience via the throttle grip and
gearshift lever.
In 'M' shift mode, gear changes can still be made by foot
control, allowing the rider to decide when to change gears.
In 'D' shift mode, the Automatic Shift Assistant really comes
into its own. Shift points are automatically selected by the engine
control unit. In both "M" and "D" modes, the rider
benefits from perfectly executed gear changes with a smooth
interruption of traction. The result is efficient motorcycle
acceleration and increased riding stability.
When shifting up, for example, the jolt associated with a
classic manual transmission with a manual clutch is largely
eliminated, as is the risk of helmet contact between rider and passenger.
Downshifts are also designed to be as smooth as possible,
minimising chassis disturbances. Specific characteristics of the
automated shift function are assigned to the different riding modes to
ensure perfect shift behaviour in each riding situation. In
combination with Active Cruise Control or front collision warning, the
networking of functions also brings the future of motorcycling to life.
Automated clutch and gear shifting for a new riding experience.
In difficult riding situations, using the clutch and throttle
takes a lot of concentration. If you are travelling with luggage and
perhaps a passenger, using the clutch and gearshift takes up
resources. The rider remains in control and has more freedom in every
riding situation with the Automated Shift Assistant. Riding becomes a
more relaxed and enjoyable experience.
The powerful boxer engine enables almost effortless pulling away
on uphill gradients, for example, thanks to automated clutch
operation, which also pays dividends in terms of better vehicle
control off-road or on difficult surfaces.
Riding pleasure takes on a whole new meaning when you choose the
automated D mode. Optimally selected gear changes create a new riding
sensation with a more intense driving experience. The right gear is
automatically selected according to the rider's individual riding
needs, resulting in a harmonious and extremely smooth driving experience.
Electromechanical clutch and gearshift actuators combined with
sophisticated electronic controls.
The Automated Shift Assistant is the logical and technical
evolution of the BMW Motorrad Shift Assistant Pro. Two electronically
controlled electromechanical actuators operate the clutch and
gearshift, enabling easy starting and automated gear changes.The
rider's shift request is transmitted to the control unit via a
gearshift lever sensor, which is actuated by the conventional
foot-operated gearshift lever. Additional sensors determine the revs
of the transmission input shaft and the clutch position. These values
are transmitted to the TCU (Transmission Control Unit), which is
closely linked to the engine control unit, for modelling and control
of the clutch, shift actuation and status.
The clutch is operated by an electro-mechanical actuator
combined with a hydraulic system with a direct hydraulic connection
between the clutch master and slave cylinders. The actuator regulates
the required clutch slip, engages the clutch when changing gear and
disengages it when stopping.
In manual shift mode "M", the rider can move the
gearshift lever in the desired direction in the usual way. If the revs
in the desired target gear are within the maximum or minimum rev
range, the shift is made directly. If the engine revs fall below a
gear-dependent minimum speed, downshifts are also performed
automatically in manual mode. This prevents the engine from stalling.
In shift mode "D" the gears are changed automatically
depending on the riding mode, engine revs, throttle position and lean
angle parameters. Gears are shifted according to the riding situation
and dynamic requirements.
The benefits of the Automatic Shift Assistant (ASA) can be
summarised as follows
· Completely eliminates the need for the rider to operate the
clutch.
· Dynamic and comfortable gear changes for more riding
pleasure.
· Choice of manual or automatic gear shifting.
·
Automatically adapts gear shifts to the rider's dynamic preferences in
automated D mode.
· Eliminates the possibility of engine stalling
due to unfavourable gear shifts.
