Route Adaptation of control strategies for a hybrid city bus

Artikel i vetenskaplig tidskrift, 1999

A series hybrid city bus with diesel engine and electric batteries is studied on a specified route. The study uses two different basic control strategies, “On/off” and “Continuous” strategy. These basic strategies are complemented in two ways. First, an “Adviser” strategy which filters the driver commands and gives driver support feedback based on the route data. Second, an “Adapter” strategy, which adapts and the control to the route, using different control depending on the vehicle present position. Simulation results are presented. They show that the adviser and adapter strategies improves both emissions and fuel consumption.
