E/E architecture for the "smartphone on wheels" provides for apps to download - eeNews Europe

Connectivity, smartphone-inspired idiosyncratic acquisition and autonomous driving are the megatrends of the mobility industry. This requires a multitude of sensors, actuators arsenic good arsenic cameras successful the conveyance – which past besides make immense amounts of information that person to beryllium transmitted and processed successful the car. With today’s modular E/E architectures, the caller features cannot beryllium afloat integrated into the vehicle. For this reason, the improvement work supplier EDAG Group has developed a conception for a zone-based, service-oriented E/E architecture arsenic portion of the “ZOBAS” backing project.

Service-oriented E/E architectures (SOA) are wide utilized successful the satellite of commercialized IT. The exertion is besides uncovering its mode much and much into the automotive environment, with functions being centralised and utilized aggregate times. An illustration of this is, for example, the extracurricular somesthesia sensor, which provides the somesthesia worth and which successful crook tin beryllium utilized by respective applications, specified arsenic aerial conditioning oregon the somesthesia show successful the centre console display. With the task extremity of processing a portion E/E architecture that is suitable for each mobility concepts, EDAG Engineering GmbH, unneurotic with the institution Technica Engineering GmbH, started the funded task “ZOBAS” successful 2020.

The completed task results person present been presented to the public. The astir important improvement goals were the instauration of SOA into the conveyance situation and the simplification of the fig of power units (ECUs) successful the vehicle. This is due to the fact that successful today’s vehicles, depending connected the scope of functions, up to 100 ECUs are distributed. In a portion E/E architecture, connected the different hand, the sensors/actuators are connected to the adjacent portion controller; the relation of the erstwhile ECUs is implemented by software. In the “ZOBAS” project, the fig of ECUs could beryllium importantly reduced depending connected the conveyance equipment. This besides importantly reduces the complexity of the wiring harness variants required for this.

Gerhard Becker, task manager of the funded task “ZOBAS”, describes the task scope of the EDAG Group: “We took attraction of the improvement of the implicit E/E architecture and the integration of the cardinal computer/zone controllers of the institution Technica Engineering. The effect is an architecture that reduces the value of the wiring harness by astir 30 percent. Another vantage of our innovative E/E architecture is the simplification of idiosyncratic wiring harnesses arsenic point-to-point connections. With a maximum magnitude of 2.5 metres, wiring harnesses tin beryllium produced automatically and installed successful the vehicle. Manufacturing tin frankincense beryllium relocated adjacent to the accumulation sites – a large competitory vantage for some car manufacturers and suppliers.” Another advantage: successful summation to the “update implicit the air”, conveyance diagnostics tin besides beryllium carried retired from anyplace successful the future.

The caller benignant of exertion improvement allows third-party providers to marque their services oregon apps disposable successful a benignant of AppStore for vehicles. Due to the precocious information measurement and the real-time requirements, automotive Ethernet is utilized for the connection betwixt the power units.

ZOBAS was funded by the German Federal Ministry of Economics. The task executing organisation is TÜV Rheinland Consulting GmbH. The results of the task are to beryllium further investigated successful a consequent probe project. The absorption is connected the integration of artificial quality for the improvement of zone-based, service-oriented EE architectures.
