The Corner Module is a highly integrated unit consisting of chassis systems, propulsion and wheel. It reduces vehicle assembly time by plug & play and skipping the brake fill & bleed process. The scalable approach with its integrated control unit allows simple wiring. Its compactness enables flexible space concepts for purpose-built vehicles, e.g. urban delivery. Thanks to the dry brake system, simplified maintenance and reusability it supports sustainable vehicle concepts.
High-Level Integration: The Corner Module
The Drive-Brake Unit represents the first step towards a fully integrated Corner Module.
- Includes suspension, shock absorber, rim, and optimized tire type.
- Optional integration of steering system for enhanced maneuverability.
OEM advantages
The innovative concept of the Corner Module offers numerous benefits for OEMs:
- Compact and highly integrated, by-wire chassis and propulsion system, eliminating the need for transmission, maximizing efficiency.
- Reduced R&D effort for manufacturers due to the ready-to-use approach.
- Plug & go concept streamlines vehicle assembly and service processes, eliminating tasks like the fill & bleed process.
- Scalable and modular construction kit for all chassis components including steering, motor, brake system, and wheels.
- Smart actuator to control all movement axes already prepared for the new E/E architectures (Software-defined vehicle).
- Exceptional steering angles enable a variety of movement functions.
- Integrated ECU reduces the need for multiple electronic control units and simplifies overall wiring.
- Supports automated driving architectures by providing safety through redundancy.
Functional scope
The Corner Module provides advanced control functions for propulsion as well as chassis and offers additional functionalities for enhanced vehicle operation:
- Parallel parking / Crab movement
- Turn-on-the-spot / U-turn
- Pivot turn (around one wheel)
- Diagonal driving
- Integrated control functions for highly efficient propulsion & chassis control
