    Author : Björn Bonthron; Christian Jonsson; [2017]
    Keywords : geogrid; cold climate; low temperature; tensile test; half-scale test;

    Abstract : Due to the findings of extensive damage on geogrids used in a road embankment in northern Sweden, the Swedish Transport Administration (TRV) started to investigate the reason of these damages. Since the geogrids were installed at low temperature, below 0°C, it was suspected that the damages were connected the low temperature. READ MORE

  3. 2. Velocity estimation in land vehicle applications - Sensor Fusion using GPS, IMU and Output-shaft

    University essay from KTH/Optimeringslära och systemteori

    Author : Christian Jonsson; [2016]
    Keywords : ;

    Abstract : In this project an alternative velocity-signal for Scania’s heavy-duty vehicles was investigated. The current velocity estimation is based on wheel-encoders obtained from other control-units like ABS- and EBSsystems. Furthermore the wheel-encoders may have poor properties at both high and low velocites. READ MORE
