Vehicle Dynamics Control for Chassis Functions

The article presents cubiX, a control software designed to manage the entire spectrum of vehicle control functions. It networks active and semi-active actuators of the chassis and driveline, utilizing highly performant control algorithms. The software's modular design allows for individual adaptation to any vehicle's requirements, simplifying engineering processes and reducing costs. As the automotive industry transitions to domain- and zone-controlled vehicle architectures, cubiX addresses the increasing software complexity by providing a collection of solutions. One of its key features is the ability to redistribute control targets seamlessly among available actuators, ensuring optimal support for the driver's desired control. The software also serves as a host for vehicle motion functions and offers a comprehensive interface to autonomous and driver assistance systems, enhancing their performance. The article delves into the four main functions of the control software: Performance Drive, Driver Assistance & Autonomous Drive, Safety, and Autonomous Drive Commercial Vehicle. It emphasizes the safety features, which include a fail-operational layer for software functions in all six degrees of freedom of vehicle motion, ensuring compliance with safety goals up to ASIL D. Additionally, the integration of machine learning into control functions is highlighted, showcasing the software's ability to meet high performance and cost-efficiency expectations. The article concludes with an outlook on future vehicle enhancements and the potential for car manufacturers to differentiate themselves with individual feature bundles.
