Development of Test Methodology to Reveal Effects of Changes in Damping Capacity of Damper on ABS Braking Performance

This paper aims to develop ABS test methodology for determining the effects of changes in damping capacity of shock absorber on ABS braking performance of a passenger vehicle. For this aim, the performance tests of ABS are separately conducted on wet and slippery surfaces of rough road by using three different damper stages. Thereby, the effects of all stages of damper on ABS braking performance are individually investigated. The test results show that this test methodology provides the effects of changes in damping capacity of damper on braking performance of ABS to be occurred in accordance with the changes in braking distance.
