Many brands and exhibitors at the IAA are still keeping their surprises under wraps. Nothing should reach the outside world until the grand premiere. But right now we can show you some highlights from the international suppliers Brose, Schaeffler Paravan and ZF Friedrichshafen.
Today long car trips are often an ordeal for passengers, but a smooth ride will impact the decision on which car to buy – at the latest when self-driving cars are available. This is because every chassis movement becomes a source of discomfort when passengers are no longer paying attention to the external conditions. If the robo-taxis of the future are to function as mobile living rooms or offices, passengers must be unaware of the road and traffic conditions. The supplier ZF Friedrichshafen is focusing on passenger comfort with its “Flying Carpet 2.0” chassis at the IAA 2019. The connected and predictive chassis helps to avoid uncomfortable movements, and to detect and counteract curves, bumps in the road and potholes. At its heart is the fully active damping system that uses four actuators to adapt the suspension movements of each individual wheel to the driving situation and road surface features.
When cornering, for example, the two inner wheels can be retracted and the outer ones extended so that the car remains virtually horizontal. The system is also effective at counteracting movements that occur during accelerating, braking, steering, or driving over bumps in the road. If the vehicle is moving fast, the system steers the front and rear wheels in the same direction to provide greater directional stability. The “cubiX” control system is the central network for this smart chassis technology. The feedback control algorithm links and coordinates the actuators. The control unit receives the data from sensors on each wheel. In conjunction with camera systems, a vehicle equipped with Flying Carpet 2.0 can detect irregularities in advance and also obstacles and objects like road traffic signs. Accordingly, the actuators can prepare for forthcoming movements.

From welcoming the driver with doors that open automatically to convenient entry – the mechatronic systems presented by the automotive supplier Brose at the IAA 2019 offer vehicle owners an entirely new access experience and pave the way to automated driving and car-sharing trends. Even from a distance the car recognizes and welcomes the driver with a projection on the ground. With a gesture, the vehicle user signals the desire to enter. The handle-free doors open automatically; a radar sensor prevents collisions.
At the same time the windows that were tinted to protect against heat and prying eyes become transparent. To facilitate entry, the steering wheel disappears into the dashboard and the seat contour adjusts automatically. The second row of seats is also completely electrified for better access to the back and can slide automatically – without making any compromises in terms of safety: an interior sensor recognizes people, pets and children’s seats in the vehicle and prevents injuries and/or damage. Buckling up is also more comfortable as the belt is presented to the passenger electrically. Brose’s concept car shows how the complete interior can be dynamically adapted to different driving situations.

The non-too distant vision of driverless cars sounds promising. You get in your car, start it up – and then sit back and let it drive you on your way. One important step in this direction is “steer-by-wire” systems that represent an alternative to the conventional steering column. The key is the digital control system which regulates all driving processes without a mechanical link between the steering wheel and the wheels. Instead, electrical impulses are transmitted to the axles within nanoseconds via cables. The “Space Drive” technology developed by Schaeffler Paravan already enables driving without hands on the steering wheel. The system is designed to include redundancy: three independent processors run continuously in parallel and simultaneously check their values with one another, to provide fail-safe operation.
This has been impressively proven on the road in real traffic: Users of “Space Drive” have already covered more than a billion accident-free kilometers. Combined with GPS, cameras, radar, and other sensors, the technology offers the basis for autonomous – fully automated and driverless – Level 4 and 5 driving. “Space Drive” has already proved its value in special vehicles for people with disabilities. “Space Drive” technology enables people with severe disabilities, even without arms or legs, to drive their car independently using a joystick. The gas pedal, brakes and steering wheel are electrically powered and electronically controlled. The “Mover” provides the supplier with an ideal development platform. Thanks to electric wheel hub drives, a 90-degree steering system and a modular design, this compact, flexible platform is suitable for a broad range of different mobility solutions such as robo-taxis or autonomous transport vehicles in urban areas.
