An electric two-speed drive for passenger cars is celebrating its world premiere in e-mobility. Compared to a single-stage drive, the range per battery charge is increased by up to five percent.
In the area of Vehicle Motion Control, the anticipatory “Flying Carpet 2.0” chassis with new damping hardware, comprehensive sensor technology, and smart algorithms increases comfort as well as dynamic handling and safety.
In the technological area of automated driving, the high-performance mainframe computer ZF ProAI RoboThink enables solutions for autonomous driving of level 4 and higher which are attractive for ride-hailing applications such as self-driving taxis.
With integrated Safety, ZF is demonstrating how the intuitive design of the interior and the scenarios for handover from automated into manual driving mode can be implemented in an optimal manner. ZF is also presenting the world’s first pre-crash system with an external side airbag: It is triggered before the collision occurs, increasing the crumple zone by valuable centimeters in side-impact crashes.
The test vehicle is based on a volume production car in which ZF has integrated a more powerful 35 KWh battery. In real-world operation, the modified mid-range model can cover 100 kilometers purely electrically on just a single battery charge – even with active auxiliary loads such as air conditioning and low-beam headlamps. This is almost three times the range of plug-in hybrids currently available on the market.
On the road toward this reality, ZF’s all-electric Vision Zero Vehicle is reaching important milestones in the transition phase from assisted to autonomous driving. Innovative safety systems enable the vehicle to see, think and act – even if the driver is distracted.
As soon as the driver has entered the premises, he can get out, activate the autonomous driving mode and then take his mandatory break. The truck will find its way to the target position, driving autonomously and electrically. Once there, the truck will unload any swap bodies it may already have loaded using its Swap Body Pilot function. Likewise, the ZF Innovation Truck will then load a new container autonomously.
The fact that the truck is able to maneuver exactly under the swap body is a central advantage of the Swap Body Pilot: This driving maneuver is extremely demanding when carried out manually, even for experienced truck drivers. Controlled by ZF proAI, a centralized computer, the ZF Innovation Truck always manages these tasks quickly and precisely.
While ZF proAI is the ZF Innovation Truck’s brain, other ZF technologies enable it to act: the active electrohydraulic ReAX commercial vehicle steering system and the TraXon Hybrid automatic transmission system, among other types of technology. The latter is characterized by a modular integrated electric motor that allows locally emission-free driving. A camera-based and laser-supported sensor setup, complete with GPS system, gives the truck its orientation and view.
The result: faster, safer and more efficient logistics processes at depots.
Its sensor set enables the vehicle to keep an eye on its surroundings. The ZF proAI central computer coordinates the functions of longitudinal and lateral guidance: This enables the shuttle vehicle to take the trailer from the truck and autonomously maneuver it to the ramp for loading or unloading. Once this has been completed, it takes the trailer back to the truck.
The vehicle's control system is interconnected with the depot's own systems. Stationary cameras at the ramp capture the rear of the semitrailer that needs to be maneuvered. An on-site computer calculates the trajectory and transfers the data to the on-board unit of the ZF Openmatics telematics system by wireless signal. The ZF proAI within the vehicle processes the information in real time and converts it into instructions for actuation of the engine, steering system and brakes.
The Innovation Van is equipped with level 4 automated driving functions. The delivery truck is designed to independently maneuver through urban surroundings, stay on course even if roads do not have lane markings, recognize both traffic lights and road signs and react to sudden hazardous situations. In addition, it can recognize and avoid obstacles such as double-parked vehicles. If two addresses are so close that the best delivery route is on foot, the Innovation Van will follow the driver as if on a virtual leash. If there is no parking available outside an address, the courier can send the vehicle ahead to the next stop, where it will look for a parking space on its own. The technologi is using an algorithm that takes into account customer requests in real time and calculates the most efficient delivery route.
Fingertip maneuverability, easy connection of implements (SafeRange and Hitch Detection), and ability to overcome any gradient, even with a tractor-trailer combination, thanks to the additional electric drive unit (Traction Management).
ZF has included an off-highway application in their innovation prototypes with the Innovation Tractor.
