The high technology cars of today contain an enormous amount of advanced electronic equipment.
To ensure the function of the electrical system these must be grounded in the body of the car. The grounding is made possible by welding unthreaded nuts into the body of the car.
If the grounding doesn’t work as it should in the car, the strangest defects can occur and they can be very hard to locate. To maintain the functionality of the entire electronic system it’s of the highest importance to get an
adequate grounding capability on the grounding element.
The project is like an element in VCBC:s work to meet Volvos goal:
“To be No. 1 in customer satisfaction in the premium segment of the car
The purpose is to increase the communication and widen the individually understanding in all segments within the company. The most important task is, and will always be, to deliver a car without any ground related problems
to the costumers even in the future.
Measurements and physical tests have been done and the results have been documented in a thorough and clear way so that it will be easy to track and identify the actual grounding connections.
The work has been of investigating character and included information retrieval, information sorting and information documentation.
The result of our work is going to be a great help regarding possible changes and investigations of the cars electrical system.
