  1. 1. Torque-Based Load Estimation for Passenger Vehicles

    University essay from Linköpings universitet/Reglerteknik

    Author : Tobias Nyberg; [2021]
    Keywords : Load Estimation; RLS; Recursive least squares; torque; torque-based; mass estimation; mass; passenger vehicle; estimation algorithm; load estimation algorithm; forgetting factor; RLS with forgetting factor;

    Abstract : An accurate estimate of the mass of a passenger vehicle is important for several safety systems and environmental aspects. In this thesis, an algorithm for estimating the mass of a passenger vehicle using the recursive least squares methodis presented. READ MORE

  3. 2. Improving Traction Efficiency in Off-Road Vehicles - A Sliding Mode Approach

    University essay from KTH/Optimeringslära och systemteori

  5. 4. Experimental investigation of rolling losses and optimal camber angle

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Bethuel Karanja; Elin Skoog; [2015]
    Keywords : ;

    Abstract : This Bachelor thesis project is an experimental investigation of the effect of camber and toe angles on rolling resistance. The experiments are done on Sleipner, a Prototype car made by KTH students, which takes part in the Shell Eco Marathon competition in Rotterdam. READ MORE

  6. 5. Virtual Vehicle Pitch Sensor

    University essay from Institutionen för systemteknik

    Author : Hamdi Bawaqneh; [2011]
    Keywords : Load distribution; Pitch angle offset; Longitudinal accelerometer; Road grade; Axle height;

    Abstract : An indirect tire pressure monitoring system uses the wheel rolling radius as an indicator of low tire pressure. When extra load is put in the trunk of a car, the load distribution in the car will change. This will affect the rolling radius which in its turn will be confused with a change in the tire pressure.
