  1. 1. An efficient deep reinforcement learning approach to the energy management for a parallel hybrid electric vehicle

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mingwei Liu; [2023]
    Keywords : HEV; EMS; Deep Reinforcement Learning; Learning Efficiency; Fuel Efficiency; HEV; EMS; Djup Förstärkningsinlärning; Inlärningseffektivitet; Bränsleeffektivitet;

    Abstract : In contemporary world, the global energy crisis and raise of greenhouse gas concentration in atmosphere necessitate the energy conservation and emission reduction. Hybrid electric vehicles (HEVs) can achieve great promise in reducing fuel consumption and greenhouse gas emissions by appropriate energy management strategies (EMSs). READ MORE

  3. 2. Hybrid Vehicle Control Benchmark

    University essay from Linköpings universitet/Fordonssystem

    Author : Ruchit Anilbhai Bhikadiya; [2020]
    Keywords : Hybrid electric vehicle; Dynamic Programming; Powertrain Modes;

    Abstract : The new emission regulations for new trucks was made to decrease the CO2 emissions by 30% from 2020 to 2030. One of the solutions is hybridizing the truck powertrain with 48V or 600V that can recover brake energy with electrical machines and batteries. The control of this hybrid powertrain is key to increase fuel efficiency. READ MORE

  4. 3. The Energy Efficiency Model of a DC Motor for the Control of HEVs

    University essay from KTH/Skolan för industriell teknik och management (ITM)

  6. 5. Camber effect study on combined tire forces

    University essay from KTH/Fordonsdynamik

    Author : Shiruo Li; [2013]
    Keywords : ;

    Abstract : Considering the more and more concerned climate change issues to which the greenhouse gas emission may contribute the most, as well as the diminishing fossil fuel resource, the automotive industry is paying more and more attention to vehicle concepts with full electric or partly electric propulsion systems. Limited by the current battery technology, most electrified vehicles on the roads today are hybrid electric vehicles (HEV). READ MORE
