The common use of UIC Pneumatic braking plant in long freight trains may involve time delays in the application of the braking forces along the convoy. This variable braking action along the train may cause heavy longitudinal efforts that could lead to wagons damaging and even cause train derailment. Simulations of these phenomena are very important both for safety and economic reasons since lo...

The paper estimates the benefits of low speed autonomous vehicle braking technologies (e.g. City Safety from Volvo) on reducing whiplash injuries, and whether driver adaptation is likely. Potential UK whiplash injury reduction and cost savings associated with autonomous braking systems are calculated. Assuming standard fleet wide fitment, predictions show autonomous braking systems (City Safety...

Kuruppu, Sandun Shivantha. M.S., Purdue University, May, 2010. Implementation and Performance Evaluation of a Regenerative Braking System coupled to Ultracapacitors for a Brushless DC Hub Motor Driven Electric Tricycle. Major Professor: Athula Kulatunga. Research related to electrical vehicles is gaining importance due to the energy crisis. An electric vehicle itself is far ahead of an internal...

This paper presents a collaborative control system for an electric vehicle chassis based on a centralized and hierarchical control architecture. The centralized controller was designed for the suspension and steering system, which is used for improving ride comfort and handling stability; the hierarchical controller was designed for the braking system, which is used for distributing the proport...

Abrasion tests were conducted using a brake dynamometer to determine the antimony (Sb) emission factor originating from automobiles. Abrasion dusts from commercially available brake pads (nonasbestos organic type) were emitted into an enclosed chamber under various braking conditions in terms of initial driving speed and deceleration. Suspended dusts inside the chamber were collected on a quart...

This paper presents a fuzzy logic model of regenerative braking (FLmRB) for modeling EVs’ regenerative braking systems (RBSs). The model has the vehicle’s acceleration and jerk, and the road inclination as input variables, and the output of the FLmRB is the regeneration factor, i.e. the ratio of regenerative braking force to the total braking force. The regeneration factor expresses the percent...

The main testing parameter of the roller brake tester is the braking force. Actually, there are some differences in results even if the same vehicle is tested on the same tester. So it will bring trouble to evaluate the braking performance accurately. Based on force analysis, the mathematical model of the roller opposite force type automobile brake tester is built in this article. And then the ...

Using the standard equation for the slowdown of a neutron star, we derive a formula for the braking index via integration rather than the conventional differentiation. The new formula negates the need to measure the second time derivative of the rotation frequency, .. ν. We show that the method gives similar braking indices for PSR B1509– 58 and the Crab pulsar to those already in the literatur...

Vehicle technology has increased rapidly in recent years, particularly in relation to braking system and sensing system. In parallel to the development of braking technologies, sensors have been developed that are capable of detecting physical obstacles, other vehicles or pedestrians around the vehicle. This development prevents accidents of vehicles using Stereo Multi-Purpose cameras, Automate...

This paper presents the formulation of a slipcontrol model for purposes of performing slip tracking of target slip. Antilock braking system modelling is performed to develop a quarter car vehicle deceleration model for braking without cornering. Input-state based feedback linearisation is applied to the highly non-linear developed antilock braking system model. Input-state feedback linearisatio...
