  1. 1. Gear engagement control for transmissions in hybrid electric vehicles

    Författare :Muddassar Piracha; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Noise and wear minimization; Dog Clutch; Hybrid Powertrain; Optimal control; LQI control; Mechanical Synchronizers; Dedicated Hybrid Transmission; Gear shifting; Drivability; Dual Clutch Transmission; Electric Powertrain; Phase plane analysis;

    Sammanfattning : Hybrid and electric vehicles have become very important for vehicle manufacturers due to stricter legislation, government incentives and customers’ growing awareness of the environmental issues. For conventional vehicles, Dual clutch transmissions (DCT) have better shift quality and efficiency than conventional automatic transmissions. LÄS MER

  3. 2. Route Adaptation of Charge strategies for Hybrid Vehicles

    Författare :Jan Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver model; modelling; control strategies; road model route adaptation; powertrain; charge strategies; simulation; hybrid vehicle; vehicle propulsion;

    Sammanfattning : For vehicles with energy storage devices, here referred to as hybrid vehicles, the control of the system is of great importance. The hardware system can not be judged without its control. This thesis describes a method for determining the potential of an arbitrary vehicle propulsion system for a prescribed driving mission.

  4. 3. On Energy Management Strategies for Hybrid Electric Vehicles

    Författare :Lars Johannesson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER

  7. 5. A Methodology for the Design of Cost Effective Hybrid Vehicles

    Författare :Jonas Hellgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuzzy logic; system engineering; model car; optimal design; evolutionary algorithms; hybrid electric vehicle; alternative powertrain; simulation; modeling; genetic algorithms; fuel cell vehicle; hybrid vehicle;

    Sammanfattning : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. LÄS MER
