This paper presents the validation method and its evaluation of the spontaneous braking and lane changing with scope awareness parameter. By using the real traffic flow data, the traffic cellular automaton model that accommodate these two driver behaviors, e.g., spontaneous braking and driver scope awareness has been compared and evaluated. The real traffic flow data have been observed via vide...

Performance on a visually guided action may improve with practice because observers become perceptually attuned to more reliable optical information. Fajen and Devaney (2006) investigated perceptual attunement, using an emergency braking task in which subjects waited until the last possible moment before slamming on the brakes. The subjects in that study learned to use more reliable optical var...

The purpose of this study was to investigate the effects of right leg restriction at the knee, ankle or both, on a driver's braking times. Previous studies have not investigated the effects of knee restriction on braking performance. A total of 23 healthy drivers performed a series of emergency braking tests in a driving simulator in either an above-knee plaster cast, a below-knee cast, or in a...

Brushless Direct current (BLDC) motors are gaining attention these days in many applications because of their simplicity in its control and high power density. Due to their usage many advances are taking place in field of automobiles in general and locomotives in particular. To have an effective control over the locomotive it is desirable to have control over starting, running and braking of a ...

Abstract: Recently, design of electric scooters (ESs) has commonly adopted brushless DC motors (BLDCMs) in place of brushed DC motors. This invention develops a new anti-lock braking system (ABS), based on a slip-ratio estimator, for ES utilizing the braking force generated by the BLDCM when electrical energy releases to the load yielding an analogous effect of ABS control in gas-engine vehicle...

To improve safety on commercial cars, a multivariable Global Chassis Controller (GCC) design, involving braking and steering systems is proposed. In case of emergency (e.g. loss of manoeuvrability), the GCC uses the braking system to handle the problem. But, in case of inefficiency of the braking system (e.g. due to low road adherence, large yaw rate error or actuator failure), detected by a br...

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...
