An antilock braking system (ABS) is one of the most important components in a road vehicle, which provides active protection during braking, to prevent wheels from locking-up and achieve handling stability steerability. The all-electric ABS without any hydraulic potential candidate for electric vehicles. To demonstrate examine algorithms, this article proposes single-wheel test bench, mainly in...

In most studies, braking of vehicle in a straight path has been considered. When vehicle moves in a curved path, the effect of camber angle and fork angle should be considered. The variable camber angle assists braking in a curved road but the turning radius of vehicle changes due to varying camber angle and fork angle. The antilock braking system (ABS) is used for enhancing vehicle directional...

There exist several problems in the control of brake systems including the development of control logic for antilock braking systems (ABS) and “base-braking.” Here, we study the base-braking control problem where we seek to develop a controller that can ensure that the braking torque commanded by the driver will be achieved. In particular, we develop a “fuzzy model reference learning controller...

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...

A range of continental-scale soil datasets exists in Europe with different spatial representation and based on different principles. We developed comprehensive pedotransfer functions (PTFs) for applications principally on spatial datasets with continental coverage. The PTF development included the prediction of soil water retention at various matric potentials and prediction of parameters to ch...

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...
