Following the successful completion of the Line-Traction 3 drive technology project and the successful functional verification of the system as a torque splitter transmission, the foundation was laid for individual wheel control of torque (“torque vectoring”) and wheel speed.
The current follow-up project builds on these findings and aims to further develop the existing drive unit in a targeted manner. The focus is on optimizing the installation space and increasing the permissible system pressures. The actuation in the hydrostatic part of the system is also being revised.
By using vehicle data—such as speeds and other parameters from the bus system—it is possible to switch flexibly between pressure and volume flow control. This enables torque and speed to be controlled at each individual wheel.
Thanks to model-based vehicle testing, a suitable operating strategy can be developed for each generic vehicle type despite the high variance in powertrain topologies and steering systems of mobile machines.
The MOBiL method for the holistic investigation of mobile machines was also developed in the context of the project.
