Distributes drive system for semitrailer truck has second drive system, which is controlled in dependence on load signal and request signal

摘要

The system includes a traction engine (12) to which a semitrailer (14) is connected which has a second drive system (26). A load sensor (24) detects the load between the traction engine and the semitrailer and generates a load signal. An electronic control unit (22) controls the second drive system dependent on the load signal and a request signal generated by an input device. An independent claim is included for a traction system for use with a traction engine.
