EB tresos 9, the new iteration of Elektrobit’s basic software for electronic control units (ECUs), enables automotive manufacturers and suppliers to develop next-generation electronic control units (ECUs) based on the current Autosar standard.

According to industry experts, the share of production vehicles with ECUs based on Autosar basic software will increase to 80 % by 2027. The software version now presented fully supports Autosar R20-11. It enables OEMs and Tier 1 suppliers to standardise according to Autosar and thus reduce development costs and time. Additionally included are the onboard intrusion detection functions of the CAN IDPS package from Argus Cyber Security.

EB tresos 9 optimises the development of software functions that comply with the latest security and safety standards. These include ISO/SAE 21434 for cyber security risk management and SAE J1979-2 for onboard emissions diagnostics. The latter standard will become mandatory for vehicles in the US from 2027. The software monitors data traffic and detects threats and anomalies. It also offers prevention mechanisms for common attack methods such as denial of service or brute force. The software also fulfils the requirements defined by Autosar for firmware over-the-air for updating ECUs during normal vehicle operation.

EB tresos 9 is a central component of Elektrobit’s comprehensive portfolio of software and engineering services. The offering provides automotive manufacturers with a one-stop shop for developing their own automotive operating systems – the harmonised software platforms that control all systems in next-generation vehicles.
