Digital and analog control via Paravan drive-by-wire system: SPACE DRIVE II
• Control via analog input
CAN1
CAN2
• Steering left & right • Gas & Brake
• Control via digital input
• PARAVAN SPACE DRIVE II CPU
� Digital control system in a
modular design for operation of
gas & brake, and / or steering by
multi-channel technology.
� Driver inputs implemented by
control units (CPUs ) and
actuators (Gas-/Brake- servo
motors & steering servo motors).
� Active redundancy in all
components including cable sets
as basis of the safety and road
approval.

Mover concepts and components as part of Schaeffler Paravan portfolio
�People Mover
�E.g. 4/8/12 people
�Cargo Mover
�Concept Mover
�Rolling Chassis
Corner Modul – 90° Steering
• 90° steering to allow precise placement on inductive
charging pads.
• New steering trajectories possible, e.g. to alive motion
sickness.
• High maneuverability in narrow streets
• Space Drive technology for steering
eWheelDrive with planetary gear
• Packaging of E/E components in between tires
(no drive shafts necessary)
• Low center of gravity possible (stability of vehicle)
�Corner Modul
�eWheelDrive
