  1. 21. Vehicle Mass and Road Grade Estimation Using Kalman Filter

    University essay from Fordonssystem

    Author : Erik Jonsson Holm; [2011]
    Keywords : Vehicle mass estimation; Road grade estimation; Extended Kalman filter; Vehicle model; Nonlinear observability; Truck sensors;

    Abstract : This Master's thesis presents a method for on-line estimation of vehicle mass and road grade using Kalman filter. Many control strategies aiming for better fuel economy, drivability and safety in today's vehicles rely on precise vehicle operating information. In this context, vehicle mass and road grade are crucial parameters. READ MORE

In developing countries potential of ICT4D still not understood, what ICTs can do in rural people life and how ICTs are used by rural people, so it has become area of discussion. READ MORE

  4. 23. 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.

  5. 24. Lodgepole pine - stability after thinning

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Merle Hämäläinen ; [2010]
    Keywords : lodgepole pine; quality; stability; thinning;

    Abstract : SCA has today almost 300 000 hectares of their forest land planted with lodgepole pine(Pinus contorta var. latifolia). Due to initial extensive planting in the 1970ies the area oflodgepole pine forests in the thinning age has grown rapidly from the end of the 1990ies. READ MORE

  6. 25. Evaluation of GPS Velocity and Altitude Data used for Road Grade Estimation

    University essay from KTH/Reglerteknik

    Author : Kristoffer Wänglund; [2009]
    Keywords : ;

    Abstract : This master’s thesis examines whether it is possible to improve an existing road grade estimator by measuring an additional signal from a GPS receiver. The existing estimator uses the differentiated altitude signal from the GPS to estimate the current road grade. READ MORE
