About the job

Carrying out a thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project within the company.

Several vital functionalities in a truck are controlled with pneumatics such as service brakes, parking brakes and gear boxes etc. Due to different reasons, pressure sensors are often not in the actuators themselves where it is most important to know the pressure.

The parking brakes in heavy vehicles got relatively complicated pneumatics at the same time as it is important to know how much force they apply to the wheels. Both transitions from parking brake to service brake with “hold” functions and back-up braking would benefit from an accurate model of the actual pressure in the actuators.

The project assignment is to design and develop a model of the pneumatic parking brake system. Preferably the model should be derived from the physical system but a black box model could also be investigated. If there is enough time, control of the parking brake actuators using the model would be desired but not required.

The project will require a theoretical survey of applicable methods, test design and planning, as well as extensive data processing and analysis.

Preferred experience and competence of applicants:

  • Mechanical engineering, applied physics, electrical engineering, vehicle engineering, or similar.
  • Signal processing
  • Sensor fusion, estimation/filtering techniques
  • Scripting/programming (e.g. Matlab)

Number of students: 2
Start date: August-October 2021
