‘Software Defined Vehicles’ emerged as key industry theme at IAA Transportation in Hannover.
To understand what it means, consider the capabilities of a conventional vehicle as being predominantly defined by its hardware. In contrast, for a software-defined vehicle, the hardware still provides the capability, but the software determines how that capability is used and managed.
Crucially, the capability of software-defined vehicles can be continually tweaked and improved, and need not be ‘set and forget’ until the vehicle is replaced or upgraded. That functionality also offers vast opportunities for on-going optimisation.
The concept has broad application across vehicles, trailers, systems, parts and equipment. Heavy vehicles already have dozens of electronic systems controlling functions such as braking, steering, suspension, powertrain, trailer functions and the wide range of Advanced Driver Assistance Systems (ADAS).
HVIA members attending IAA were treated to a detailed technical presentation at the Knorr-Bremse stand that covered the company’s advanced connectivity capabilities, which included a new Online Configuration Tool (OCT), which is a cloud-based platform for configuring trailer systems, and a new Software Update Management System (SUMS), which provides remote updates to trailer brake control systems and tyre pressure monitoring.
Similar solutions and concepts were also on display at the ZF stand, with a unique new capability also on display – the Truck Trailer Link (TTL) concept. TTL is envisaged to eventually replace conventional wiring connectors with a single truck-trailer connection to enable bi-directional, cyber-secure data transfer.
Applications under consideration include incorporating trailer video into driver assistance systems, and in-cabin control of trailer sub-systems such as lift axles and lighting.
For global truck and trailer systems supplier Jost, the concept took the form of its in-house digital platform that is able to manage its Digital Tipping Solution (DTS), its new ePTO product and the KKS coupling, an automated fifth wheel connection available to reduce incorrect connections and support future autonomous operations.
The next generation of trucks and trailers will be more connected, and more intelligent than before, and will become increasingly defined by the software that coordinates their underpinning hardware systems, which is set to offer vast opportunities to update and improve them throughout their working lives.
