Heavy Duty Vehicle Dynamics Related to Braking, Steering and Tyres - Swedish Research and Proposals by VTI 892502

Research concerning heavy duty vehicle dynamics related to braking, steering and tyres has been conducted by the Swedish Road and Traffic Research Institute (VTI) for about 20 years. The aim has been to develop test procedures and propose minimum performance requirements primarily for vehicle combinations. This paper summarizes results concerning dynamic stability in a double lane change manouevre at constant speed, overturning stability, emergency antilock braking performance under winter conditions in terms of stability, steerability and braking performance during emergency braking in a turn on ice and during straight line braking on ice, split friction and transition from low-to high friction. Hybrid simulation and a tyre tester are also described.
