  1. 1. Evaluation of Traction Control Systems for an Electric Forklift Truck

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Mattias Karlsson; Sebastian Johansson; [2021]
    Nyckelord :forklift; traction control; maximum transmissible torque; model following control; sliding mode control; slip; asr; tcs; mfc; mtte; smc; electric vehicle; master thesis;

    Sammanfattning : This thesis evaluates different controllers for traction control on an electric forklift truck and has been done in cooperation with Toyota Material Handling Manufacturing Sweden. The need for a traction control system has increased with the introduction of lithium-ion batteries replacing the older lead-acid batteries, reducing the battery weight and therefore the downward force on the driving wheel increasing the risk for slip.

  3. 2. Wheel Induced Vibrations on Heavy Vehicles

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Hector Garcia; Emma Smith; [2013]
    Nyckelord :;

    Sammanfattning : Some of the most significant comfort disturbances in heavy vehicles can often be related to the wheels. In those cases, the vibration of the vehicle is excited by for example force variations within the tire, ovality of the tire or imbalance in the wheel. LÄS MER

  4. 3. Modeling of Engine and Driveline Related Disturbances on the Wheel Speed in Passanger Cars

    Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Robert Johansson; [2012]
    Nyckelord :Wheel speed disturbance; driveline model; engine model; torsional vibration; diesel;

    Sammanfattning : The aim of the thesis is to derive a mathematical model of the engine and driveline in a passenger car, capable of describing the wheel speed disturbances related to the engine and driveline. The thesis is conducted in order to improve the disturbance cancelation algorithm in the indirect tire pressure monitoring system, TPI developed by NIRA Dynamics AB. LÄS MER

  5. 4. Data Requirements for a Look-Ahead System

    Magister-uppsats, Institutionen för systemteknik

    Författare :Erik Holma; [2007]
    Nyckelord :Look Ahead; Cruise Controller; MPC; Topographic Road map; Input data;

    Sammanfattning : Look ahead cruise control deals with the concept of using recorded topographic road data combined with a GPS to control vehicle speed. The purpose of this is to save fuel without a change in travel time for a given road. This thesis explores the sensitivity of different disturbances for look ahead systems. LÄS MER

  7. 5. Evaluation of an Active Steering System

    Uppsats för yrkesexamina på avancerad nivå, KTH/Reglerteknik

    Författare :Adrian Rodriguez Orozco; [2004]
    Nyckelord :;

    Sammanfattning : A steering aid system called active steering is evaluated by simulating different driving events. The active steering solution, which is taken from a scientific paper, has been implemented in Matlab/Simulink. LÄS MER
