    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

    Abstract : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. READ MORE

  4. 2. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes

    Author : Lars Johannesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Management; Powertrain Control; Predictive Control; Dynamic Programming; Vehicle Telematics; Hybrid Electric Vehicle; Hybrid Electric Powertrains;

    Abstract : At the highest level in the powertrain control system in a hybrid electric vehicle an energy management controller interprets the driver’s pedal actions as a torque that is to be delivered at the powertrain output. The energy management controller distributes this torque between the engine and the electric machines and decides when to change gear and when to turn off the engine for pure electric propulsion.

    Abstract : This thesis addresses methodological issues in estimating the value of a statistical life (VSL). Two main approaches have been used to estimate the VSL, the indirect and direct methods; the indirect method is based on revealed preferences, such as the wage premium demanded for a risky job.
