Overview
The Braunschweig City Driving Cycle cycle was developed at the Technical University of Braunschweig. It is a transient driving schedule simulating urban bus driving with frequent stops.
The Braunschweig Cycle was frequently used in various research projects, as well as for some equipment certification programs. Since the introduction of the transient ETC cycle, the role of the Braunschweig cycle has diminished. Comparison studies indicate that the ETC produces about 40% lower power output and 30 – 70% lower regulated emissions than the Braunschweig cycle (AB Svensk Bilprovning Motortestcenter, Report 9707, 1997).
