NX NextMotion

Central control unit

Fail Operational: The scalable and multi-redundant central control unit NX NextMotion is the heart of Arnold NextG's Safety-by-Wire® technology. The quad-redundant and modular software and hardware architecture of NX NextMotion allows simultaneous control of all primary and secondary functions. The system meets the stringent requirements of IEC 61508 and ISO 26262 ASIL-D for functional safety. Thanks to our intelligent safety concept and the latest chip technology, we are able to integrate customer software into our multi-redundant system architecture.

One step ahead

Our flexible, platform-independent modular system meets all drive-by-wire, steer-by-wire, and brake-by-wire requirements, up to revolutionary system-on-chip (SoC) solutions. With the modular and scalable NX NextMotion architecture, we are already prepared for future mobility scenarios. Thanks to the latest chip technology and optimal computing power, we can seamlessly integrate additional customer-specific software modules into the NX NextMotion control unit. The use of our technology accelerates our customers' development processes. We are capable of meeting specific requirements from almost all industries, making our solutions highly versatile. Our technology ensures maximum safety, reliability, and efficiency.
