Abstract
The upcoming EURO 7 regulation requires significant CO2 reductions in road freight, targeting towing vehicles and semitrailers. Semitrailers face a 10% reduction goal, with limited gains from aerodynamic tweaks and low rolling resistance tires, making electrification the most promising solution. Electrified semitrailers hybridize diesel-powered setups, suiting both long- and short-haul routes. However, mass adoption is hindered by interoperability issues, as current designs depend on tractor-specific CAN-data, limiting compatibility across OEMs and models. This paper reports on the first results of CHANGE project which overcomes the challenge by creating an interoperable electrified semitrailer that bypasses CAN-data. Instead, CHANGE uses a load-sensing kingpin coupling, vehicle state estimation, and data from the semitrailer’s Electronic Brake System (EBS). The objective is to ensure robust traction and energy recuperation through a predictive controller, balancing braking and traction to optimize energy use based on mission profiles.
