Problems concerning energy consumption and emissions in urban areas are well known and have received a great deal of attention. This paper focuses on one specific automotive area: city bus traffic. One promising way to control emissions from city buses is to use hybrid propulsion systems. A hybrid vehicle has an obvious potential to limit fuel consumption and undesired emissions compared to a traditional one. The vehicle studied is a series electric vehicle where the power from a diesel engine is transferred via an energy storage. The vehicle is driven along a specified route. This study uses two different basic control strategies. These strategies are complemented in two ways. First, an 'Adviser' which filters the drivers command and/or gives the driver support feedback. Second, a kind of adaptation to the route is made. This is carried out by using different control depending on the position along the route. Simulations using mathematical models give levels of emissions and fuel consumption. An improvement in these aspects are achieved by adapting the control and by using the described 'Adviser'.
