The practical problems that usually come up during the on-vehicle testing of motor car shock absorbers have been discussed. Results example tests carried out to EUSAMA standard procedure were compared test results obtained with using newer methods, i.e. phase angle method and half power bandwidth (HPBM). issue incompatibility typical excitation applied by diagnostic suspension testers one often...

OBJECTIVE Overbraking and underbraking have been shown to be common factors in motorcycle crashes. Antilock braking systems (ABS) prevent wheels from locking during braking and may make riders less reluctant to apply full braking force. The objective of this study was to evaluate the effect of ABS in fatal motorcycle crashes. METHODS Motorcycle drivers involved in fatal crashes per 10,000 reg...

The passive and also the active safety systems of the vehicles evolved in the last decades. Beside the safety system of cars and trucks the smaller vehicles like the motorbikes, scooters, e-bikes and bicycle’s systems evolved as well. The aim of the project was to create and develop a prototype bicycle that uses a hydraulic type antilock braking system. The paper presents shortly the dynamics o...

To maintain the stability trajectory of vehicles under critical driving conditions, anti lock-anti skid controllers, consisting of four anti-lock sub-controllers for each wheel and two anti-skid sub-controllers for left and right pair wheels have been separately designed. Wheel and body systems have been simulated with seven degrees of freedom to evaluate the proper functioning of controllers. ...

The “Reliability Analysis of an Anti-lock Braking System using Stochastic Petri Nets” is a work in progress and an extension to the work presented in the paper “Specification, Safety and Reliability Analysis Using Stochastic Petri Net Models”[9]. The current work attempts to model the Anti-lock braking sub-system of a vehicle system using Stochastic Petri Nets. The reliability analysis is under...

The paper presents objectives and results of a case study in computer support for failure mode and effects analysis and for the creation of repair manuals in the domain of automotive systems. Model-based prediction and diagnosis reflect the requirements of these tasks. More specifically, qualitative models of system components are necessary for both capturing the available knowledge and achievi...
