Abstract

The article presents possibilities of extending the scope of ABS / ESP systems control as part of periodic vehicle technical inspection. It was proposed to check the functioning of the ABS / ESP system based on the evaluation of its effects in the form of dynamic changes of braking forces measured on the roller diagnostic stand. The tested system is started by a diagnostic tester through the OBD socket in the car during the implementation of active tests. The effect of the system is checked on the basis of the analysis of the course of braking forces. This allows to detect those mechatronic system failures that are not detected by on-board diagnostic systems. The algorithms for control of ABS and ESP modulators using diagnostic testers are presented.
