Today, cars are becoming increasingly intelligent, and the connection between driver and machine is increasingly intuitive. Even the most ordinary components, such as automatic transmissions, are equipped with technologies that are far from what we know from the past. One such example is the hidden function of the transmissions in some BMW models, which uses the navigation system to predict the road ahead and optimize gear changes.
This technology is known as "Predictive Gearshifting" or "Predictive Gearshifting". At first glance, it works like any other automatic transmission. But when it's active, it uses data from the car's navigation system to make real-time gear-shifting decisions.
How does it work?
The car is constantly monitoring GPS and digital map data. It knows in advance that:
A sharp turn: When the system "sees" a sharp turn ahead, it automatically downshifts one or more gears to prepare the car for the sharper maneuver. This ensures that the engine is at the optimum rpm for exiting a bend without having to accelerate hard or losing power.
Roundabout: Before entering a roundabout, the system can downshift, ensuring a smooth and safe entry and exit.
Gradient or downhill: When the vehicle is driving on a steep road, the system can maintain a lower gear to utilize the engine's braking effect and reduce the load on the brakes. When descending, it can drop down a gear to help maintain speed and prevent the brakes from overheating.
Why is it useful?
This technology is almost imperceptible to the driver, but it offers a number of advantages:
Better driving dynamics: By anticipating the road, the car is always prepared for the next maneuver, making driving smoother and more enjoyable.
Increased efficiency: The system optimizes fuel consumption by avoiding unnecessary acceleration and braking, which is especially useful when traveling on mountain roads or in built-up areas.
Increased safety: By preparing the car for turns or descents, the technology contributes to a more stable and controlled driving.
Although not advertised as a "essential" extra, "Predictive Gearshifting" is a prime example of how a car can become smarter without it being obvious to the driver. It shows that the future of the automotive industry lies not only in autonomous driving, but also in creating an even more intuitive and intelligent connection between man and machine.
