Yes / An experimental study of wheel movement arising from compliance in the front suspension and steering system of a passenger car during braking is presented. Using a Kinematic and Compliance (K&C) test rig, movement of the front wheels and the suspension sub-frame, together with corresponding changes in suspension / steering geometry under simulated braking conditions, were measured and compared with dynamic measurements of the centre points of the front wheels. The resulting knowledge of front wheel deflections has enabled the causes and effects of steering drift during braking to be better understood in the design of front suspension systems for vehicle stability.

The doctoral thesis deals with aspects of pre-certification tests of electromagnetic immunity in the automotive industry. The thesis analyses commonly used test methodology and mentions that standardized electromagnetic immunity tests performed by certified testing centres, which are extremely expensive and represents a considerable time load in the development of the vehicle. The thesis therefore proposes innovative ways for replacement of certification tests with an acceptable level of uncertainty. Key methods are seen in numerical simulations and modified test procedures when the vehicle is exposed by electromagnetic field. The proposed methods are deeply explored and their benefits are discussed and support by number of experiments. The results obtained with the pre-certification methods are objectively compared with the results of the certification measurements by FSV method. The work brings a proposal for a comprehensive test methodology including a discussion of risks and uncertainties with related issues.
