NX NextMotion

One step ahead

Our flexible modular system enables the implementation of any drive, steer or brake-by-wire requirements up to revolutionary system-on-chip (SoC) solutions. Thanks to the modular and scalable system architecture of NX NextMotion, we are already meeting the requirements of future mobility scenarios. By using the latest chip technology and maximum computing power, we are able to integrate additional software modules from our customers into the NX NextMotion ECU. Furthermore, it is possible to cover requirements from the aviation as well as the maritime sector.

Predictive Vehicle Dynamics Estimator

Arnold NextG's patented vehicle dynamics estimator uses advanced algorithms to reliably predict constantly changing driving conditions. We are thus laying the foundation for the next generation of active driving safety and assistance systems, which are essential to the goal of minimizing traffic fatalities by 2030. The technology also dramatically improves torque vectoring and enables safe driving even at the limits of driving dynamics, which was previously the preserve of racing drivers.

High-precision estimation

  • of the longitudinal and lateral speed of the vehicle
  • of slip on all tires
  • the roll and pitch angle of the vehicle
  • the road and tire friction value (grip)
  • safety-relevant tire parameters (skew stiffness, wear)

Driving dynamics use cases

  • Replacing the previous stability control system with steer-by-wire steering intervention
  • Implementation of virtual rear-axle steering

Use cases assistance systems

  • Validation of driving commands of the autonomous driver
  • Execution of driving commands adapted to the driving and environmental situation
  • Warning of worn tires
  • Rollover warning for off-road vehicles with precise pitch and roll angles

Why By Wire?

Safer, more flexible, less expensive

The elimination of mechanical connections in steering, braking or driving systems not only enables the complete redesign of the vehicle interior or the development of new functions and features - it also makes a significant contribution to reducing complexity and costs. The digitization of previously manual or hydraulic vehicle functions also guarantees maximum precision as well as unique control, representing a true revolution in the entire vehicle and mobility industry.

Your benefits:

  • Improved driving comfort thanks to variably adjustable steering ratio
  • Individually applicable/adjustable driving dynamics
  • New interior concepts due to the elimination of mechanical connections (steering, brakes, etc.)
  • Improved safety through real-time networking of safety-related systems
  • Standardization and simplification of vehicle and chassis platforms
  • Increased safety through elimination of the steering column
  • Elimination of human error through automated steering and braking intervention
  • Increased development speed and reduced effort
  • Stowable input devices
  • Central interface for automation of technical process flows
  • Prerequisite for autonomous driving
  • Savings in manpower and simultaneous increase in effectiveness (24/7)

Barrier-Free Mobility

An electric wheelchair that overcomes barriers
Inclusion is what drives us! Individual mobility for people with severe physical disabilities is not just a question of finding the right vehicle - it is part of Arnold NextG's founding promise. Part of this holistic approach is the development of the world's first autonomous electric wheelchair, which raises individual mobility and independence to unprecedented levels. Depending on the handicap and individual needs, this wheelchair adapts to the needs of its users - from fail-safe joystick steering and an assisting robotic arm to chin and eye control. The remote function allows the wheelchair to be controlled remotely if necessary and also forms the basis for all automated and autonomous driving functions, including mind control. The core of the new development is the globally unique and multi-redundant NX NextMotion central control unit, which covers all requirements of individual mobility thanks to its scalable and powerful system architecture.
