A research in the field of technical diagnostic of vehicle suspension condition will be finished by the end of the 1st year to enable a start of the development of software applications. Sequentially manufacturing documentation will be prepared and the tester prototype will be manufactured and tested extensively. This project phase should be finished by the end of the 2nd year. Then the experimental development will be introduced to the process, based on prototype tests. The purpose of this phase is to verify high accuracy and repeatability of the suggested methods on a wide range of passenger vehicles. Therefore a lot of tests will be performed with both new and used vehicles of different age and from various manufacturers. The real condition of these examined shock absorbers will be accurately measured using a special test rig which requires disassembly of the shock absorber (by the end of 3rd year).
