Upgrading Of Two Position Anti-skid Valve For Braking System Of Urban Rail Transit Vehicles
نویسندگان
چکیده
Abstract Based on the structural principle of existing two-position anti-skid valve for urban rail vehicles, has been modified to increase pressure maintaining position based original only brake and release position, so as upgrade three-position valve. As pressure-maintaining is added, maximum braking force shall be kept far possible under premise control train, shorten distance ensure driving safety.

Hydraulic anti-lock, anti-skid braking system using fuzzy controller
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. ...

A Novel Anti-Lock Braking System for Electric Vehicles
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...
متن کاملUrban Rail Transit System Operation Optimization A Game Theoretical Methodology
The Urban Rail Transit (URT) has been one of the major trip modes in cities worldwide. As the passengers arrive at variable rates in different time slots, e.g., rush and non-rush hours, the departure frequency at a site directly relates to perceived service quality of passengers; the high departure frequency, however, incurs more operation cost to URT. Therefore, a tradeoff between the interest...

−Reducing the number of traffic accidents is a declared target of most governments. Since dependence on driver reaction is the main cause of road accidents, it would be advisable to replace the human factor in some driving-related tasks with automated solutions. In order to automate a vehicle it is necessary to control the actuators of a car, i.e., the steering wheel, accelerator, and brake. Th...
