FEV has developed a software system for determining vehicle weight in real time. This allows accurate operating strategies to be produced for everything from energy management to navigation and charging. The ability to identify environmental influences and the load that the vehicle is carrying at any given time makes it possible to provide precise forecasts of the vehicle's electric range and the ideal route to take. In addition, a new European Union directive specifies that from May 2021 all commercial vehicles registered in the EU must be fitted with a device to determine the weight of the cargo on board. The software system developed by FEV evaluates the vehicle's existing sensor data, correlates it and compares it with a dynamic vehicle model that is also based on sensor data. As a result, the system is both affordable and flexible and can be integrated into any small car or truck. The algorithms are currently undergoing further development and validation to prepare them for use in the next generation of production models.
