TruckMaker is an advanced real-time simulation platform designed specifically for the needs of heavy-duty vehicle development and testing, encompassing trucks, construction machinery, buses, semi-trucks, and specialized vehicles. This solution facilitates precise modeling of real-world testing conditions in a virtual environment, thereby enhancing the efficiency of development workflows. By aligning with the automotive systems engineering methodology, TruckMaker allows for continuous development, calibration, testing, and validation of complete vehicle systems within realistic virtual scenarios through test driving simulations. It provides a powerful, real-time vehicle modeling capability that enables the creation of virtual prototypes at the initial phases of the development process. Additionally, users can customize their simulations by integrating their own components or hardware models, further tailoring the simulation experience to their specific requirements. This flexibility and realism make TruckMaker an invaluable tool in the heavy-duty vehicle industry.
