Vehicle Suspension and Steering (5 cr)

Objectives (course unit)

Students:
- know steering structures, suspension, suspension damping, wheel and tire structures and their effects on the handling characteristics of the vehicle
- know the braking system structures.

Content (course unit)

The course covers steering, wheel angle effect to the driving characteristics, tilt and nod center determination, suspension and damping effect on drive comfort and safety, design of suspension and damping, braking system engineering.
