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...

Energy and environmental protection have already become two principal themes of the development for the world in our times. The hybrid-electric vehicle (HEV) is considered as a new-type car with strong enforceability, which can deal with energy crisis, pressure of environmental protection and realize the sustainable development of the auto industry at present. This paper proposed that the contr...

"The anti-lock braking system is a safety equipment that prevents the vehicle wheels from locking up under emergency, panic, or harsh conditions, ensuring steering control during and reducing distance. This studied by automotive engineers for performance comparisons determining optimal methods. For this reason, paper presents method to mathematically model system. The obtained afterwards used i...

Abstract Regenerative braking is a technique that employs electric motors to convert the dynamic mechanical energy from motor’s spinning rotor and any attached loads into electricity. However, such type of regenerative can only slow but not stop vehicle because there too little excite motor acting as generator at low speeds. Therefore, this paper presents unique flywheel-based system for railwa...

The Anti-lock braking system (ABS) is the most common safety system in the vehicles, which works to increase the generating braking force between the tire and the road surface in way to keep the stability in vehicles during braking. The high nonlinearity due to the interaction between the tire and road, the uncertainties in vehicle dynamics always exist and using the standard PID controller wil...

In this paper, we present the general context of the research in the domain of analysis and modeling of mechatronic systems. In fact, we present à bibliographic review on some works of research about the systemic analysis of mechatronic systems. To better understand its characteristics, we start with an introduction about mechatronic systems and various fields related to these systems, after we...

Anti-lock Braking System (ABS) is the most important active safety system for passenger cars, but unfortunately the literature is not really precise about its description, stability and performance. This research improves a five-phase hybrid algorithm based on wheel deceleration and validate it on a tyre-in-the-loop laboratory facility. Five relevant effects are modelled so that the simulation ...

In order to solve the problems of wheel locking and loss vehicle control due understeering or oversteering during braking energy-recovery process hydraulic regenerative system (HRBS), aiming at characteristics chassis domain that can realize coordinated work among various systems, a cooperative strategy HRBS based on was proposed. Firstly, test bench built, accuracy simulation model verified by...
