Parameter Estimation of a Countershaft Brake for Heavy-Duty Vehicles with Automated Mechanical Transmission

Lateral Control of Heavy Duty Vehicles for Automated Highway Systems

Three results pertaining to lateral control of heavy duty vehicles on Automated Highway System are presented. First, a time domain, frequency domain and pole/zero analysis of the linearized model for lateral control of tractor-trailer vehicles is presented. The steering response subject to variation of speed, road adhesion and look-ahead distance is studied. Based on the analysis, a simple base...

Speed gradient approach to longitudinal control of heavy-duty vehicles equipped with variable compression brake

This paper considers a longitudinal speed control problem for heavy-duty vehicles equipped with variable compression brake. The use of compression brake reduces the wear of the conventional friction brakes, and it is, thus, a preferred way of controlling the vehicle speed during a steady descent or noncritical braking maneuvers. To perform more aggressive (critical) braking maneuvers or control...

Selective Catalytic Reduction for Heavy-duty and Light-duty Vehicles

Whereas previous emission limit values could be met by primary engine control measures, the limits for PM and NOx from heavy duty engines in 2008/09 (Euro V) and diesel passenger cars in 2014/15 (Euro 6) represent a challenge for the developers of diesel engines and vehicles. Due to the thermodynamics of the Diesel combustion process, it is difficult to optimise the combustion process for both ...
