Video: Safety Chassis With Electric All-wheel Drive Developed For Motorcycles
Four-wheel drive has already proven itself in many dangerous driving situations. But for motorcycles, this has so far hardly been realized due to its construction and especially not for e-bikes. Compact hub motors should open up completely new possibilities here. The recuperation, i.e. energy recovery, and efficient torque distribution developed in the joint project increases the efficiency of the electric drive and results in an efficiency gain of 26%. The findings of the project should be transferable to all classes of two-wheelers with an electric drive.
Increase driving stability and safety
The joint research project "Safety suspension with electric all-wheel drive for e-bikes & e-motorcycles" was completed in mid-July. The project partners Gigatronik, ID-Bike, IPDD and the Institute for Measurement, Control and Microtechnology at the University of Ulm developed a two-wheeler with all-wheel drive for driving stabilization and recuperation. This enables a correspondingly adjusted torque distribution between the drives on the front and rear wheels when accelerating and decelerating, which increases driving stability and safety. The recovered energy enables short-term peak performance or increases the range.

System records current driving situation
To be able to intervene in dangerous driving situations, the system must record the current driving situation. This is done via sensors on the e-bike, which are evaluated by software for regulating driving stability on the control unit. The software was developed at the University of Ulm. The future situation and the likely reaction of the driver can be calculated from the history and current condition. The torque control of the front and rear wheels can then be used safely.
