BMW has introduced its new Automated Shift Assistant (ASA) that can remove the necessity for a clutch lever on bikes, and make use of the foot-operated shift lever elective.
A development seems to be growing that producers are providing semi-automatic or totally computerized transmissions on bikes (Honda’s new E-Clutch involves thoughts), and BMW has introduced ASA, which guarantees to remove the necessity for a clutch lever whereas nonetheless permitting the rider to decide on to shift manually with the foot management. A totally computerized mode will remove this, as nicely.
Right here is the press launch from BMW:
Woodcliff Lake, NJ – Could 2, 2024 . . . With the brand new Automated Shift Assistant (ASA), BMW Motorrad presents an revolutionary technical answer that makes driving easier and extra snug. True to the motto “Simplify your journey”, the driving expertise is enhanced by automation of the clutch and kit shifting course of, with out sacrificing the emotionally vital dynamics of shifting.
The Automated Shift Assistant includes a intelligent purposeful design during which two electromechanical actuators automate the clutch and gearshift of the six-speed transmission, which is the principle distinction to a traditional shift assistant. There isn’t a want for a hand lever to function the clutch manually. Beginning, stopping, and maneuvering are all made straightforward with the Automated Shift Assistant.
Using with the Automated Shift Assistant turns into extra pleasing due to quick, exact, rev-and load-adapted gear modifications. The rider’s workload is diminished, which makes driving extra pleasing. As well as, the Automated Shift Assistant creates a extra direct reference to the highly effective boxer engine, because the exact clutch actuation makes it simpler to manage the driving expertise by way of the throttle and gearshift lever.
In ‘M’ shift mode, gear modifications can nonetheless be made by foot management, permitting the rider to determine when to vary gears.
In ‘D’ shift mode, the Automated Shift Assistant actually comes into its personal. Shift factors are robotically chosen by the engine management unit. In each “M” and “D” modes, the rider advantages from clean and completely executed gear modifications, leading to environment friendly bike acceleration and elevated driving stability.
When shifting up, for instance, the potential jolt related to a basic guide transmission with a guide clutch is basically eradicated, as is the chance of helmet to helmet contact between rider and passenger.
Downshifts are additionally designed to be as clean as potential, minimizing chassis disturbances. Particular traits of the automated shift operate are assigned to the totally different driving modes to make sure excellent shift conduct in every driving state of affairs. Together with Lively Cruise Management or entrance collision warning, the networking of features brings the way forward for motorcycling to life.
Automated clutch and kit shifting for a brand new driving expertise.In tough driving conditions, utilizing the clutch and throttle takes loads of focus. In case you are travelling with baggage and maybe a passenger, utilizing the clutch and gearshift takes up assets. The rider stays in management and has extra freedom in each driving state of affairs with the Automated Shift Assistant. Using turns into a extra relaxed and pleasing expertise.
The torquey boxer engine permits nearly easy begins on uphill gradients, for instance, due to automated clutch operation, which additionally pays dividends when it comes to higher automobile management off-road or on tough surfaces.
Using pleasure takes on a complete new that means if you select the automated D mode. Optimally chosen gear modifications create a brand new driving sensation. The appropriate gear is robotically chosen in line with the rider’s particular person driving wants, leading to a harmonious and intensely clean driving expertise.
Electromechanical clutch and gearshift actuators mixed with subtle digital controls. The Automated Shift Assistant is the logical and technical evolution of the BMW Motorrad Shift Assistant Professional. Two electronically managed electromechanical actuators function the clutch and gearshift, enabling straightforward beginning and automatic gear modifications. The rider’s shift request is transmitted to the management unit by way of a gearshift lever sensor, which is actuated by the traditional foot-operated gearshift lever. Extra sensors decide the revs of the transmission enter shaft and the clutch place. These values are transmitted to the TCU (Transmission Management Unit), which is carefully linked to the engine management unit, for management of the clutch and shift actuation.
The clutch is operated by an electro-mechanical actuator mixed with a hydraulic system with a direct hydraulic connection between the clutch grasp and slave cylinders. The actuator regulates the required clutch slip, engages the clutch when altering gear and disengages it when stopping.
In guide shift mode “M”, the rider can transfer the gearshift lever within the desired course within the normal approach. If the revs within the desired goal gear are inside the most or minimal rev vary, the shift is made immediately. If the engine revs fall beneath a gear-dependent minimal velocity, downshifts are carried out robotically in guide mode. This prevents the engine from stalling.
In shift mode “D” the gears are modified robotically relying on the driving mode, engine revs, throttle place and lean angle parameters. Gears are shifted in line with the driving state of affairs and dynamic necessities.
The advantages of the Automated Shift Assistant (ASA):➢ Utterly eliminates the necessity for the rider to function the clutch.➢ Dynamic and cozy gear modifications for extra driving pleasure.➢ Selection of guide or computerized gear shifting.➢ Mechanically adapts gear shifts to the rider’s dynamic preferences in D mode.➢ Eliminates the opportunity of engine stalling throughout gear shifts.
