Most of the energy is wasted into heat due to conventional braking, so an optimal braking strategy needed. A Regenerative utilizes kinetic engine electrical by changing function electric machine a generator. The regenerative system uses Switched Reluctance Machine (SRM) which has several advantages; simple construction, does not require maintenance, and return battery. method that can be used i...

In this paper, a bidirectional AC DC converter is analyzed. The converter applies a half bridge thyristor rectifier and a recuperating thyristor bridge instead of a braking resistor. Recuperating mode of the converter is focused in the analysis, and it is shown that the converter exposes two operating modes within the recuperating mode, one characterized by negligible, and the other one charact...

This paper proposes an effective method of energy regeneration during braking for a dc motor or internal combustion(IC) engine. During the braking period, instead of dissipating the kinetic energy in the brake shoes and poles in the form of heat, this energy is recovered using a switched reluctance generator that is mechanically coupled to the shaft of prime mover. Here the DC motor or the IC e...

Conclusive evidence has demonstrated the critical importance of highly automated driving systems and regenerative braking in improving safety economy. However, traditional system cannot be applied to vehicles. Therefore, this paper proposes a fully decoupled for vehicles, which two working modes: conventional redundant braking. Aimed at above modes, respectively pressure control algorithm, base...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

Timing is often seen as the most important property of systems after function, and safety-critical systems are no exception. In this paper, we consider how timing is typically treated in safety assurance and, in particular, the safety arguments being proposed by industry and academia. A critique of these arguments is performed based on how systems are generally developed and how evidence is gat...

Abstract The application of electric vehicles leads to a change in the principle operation and functioning some systems vehicle, which also lead concept vehicle itself. One those that has new concept, differs from powered by IC engines, is braking system. previous function system was stop i.e. reduce speed safe way. In case vehicles, friction brakes were retained, with addition regenerative rol...

This work presents a hydraulic anti-lock braking system (ABS) for a motorcycle. The ABS has a hydraulic modulator and an intelligent controller. The hydraulic modulator is analyzed, and then equipped on a scooter for road tests. The intelligent controller controls the hydraulic modulator by estimated vehicle velocity to calculate the slip ratio of the wheels in real time. The performance of the...
