Rig for testing active safety system for two-wheelers

Abstract

The paper deals with the measuring equipment used to conduct two-wheeler braking system testing. When in motion, two-wheelers are initially less stable than cars, which necessitates creating more advanced active safety systems (ASS) that take into account the characteristics of their motion. Active safety systems available today operate on the basis of control algorithms that use kinematic parameters as sources of information, which requires performing approximate estimation of the relative slip in the contact patch between the wheel and the road. This leads to more complex control algorithms and increased cost of the entire system. To improve the safety of twowheelers, an active safety system operating on the basis of control algorithms which use primary information about road conditions as sources of information must be developed. The primary information includes a number of forces, brake power, the magnitude of lateral forces, normal reactions in the contact patch between the wheel and the road. When creating and testing new anti-lock braking systems and their improved control algorithms, rig and road tests must be performed where testing conditions closely represent the real modes of operation of the active safety systems being developed. To conduct the rig tests under conditions close to real-world scenarios, a specialized rig for two-wheelers must be developed and created.
