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
