The use of regenerative braking systems is an important approach for improving the travel mileage electric vehicles, and auxiliary hydraulic energy recovery system can improve efficiency process. In this paper, we present algorithm optimizing a (HRBS) based on fuzzy Q-Learning (FQL). First, built test bench, which was used to verify accuracy simulation model. Second, combined HRBS with vehicle ...

The aim of this work is to develop a magnetorheological brake (MRB) system that has performance advantages over the conventional hydraulic brake system. The proposed brake system consists of rotating disks immersed in a MR fluid and enclosed in an electromagnet, which the yield stress of the fluid varies as a function of the magnetic field applied by the electromagnet. The controllable yield st...

In order to address the problems of low energy storage capacity and short battery life in electric vehicles, this paper, a new electromechanical-hydraulic power coupling drive system is proposed, an vehicle proposed based on system.

This paper provides a hierarchical control strategy for cooperative braking system of an electric vehicle with separated driven axles. Two layers are defined: the top layer is used to optimize the braking stability based on two sliding mode control strategies, namely, the interaxle control mode and signal-axle control strategies; the interaxle control strategy generates the ideal braking force ...

This paper proposes the use of Electromechanical Brakes (EMB) in combination with regenerative braking in PHEV so braking force can be distributed to front and rear axles according to an optimal curve instead of a linear line. Therefore, more braking force will be distributed to front axle, which will offer more kinetic energy for regenerative braking. Fuzzy logic control is used to allocate br...

Braking in hoisting drives is used to reduce the speed of the load (cargo) or to stop it completely. Braking can be realized using electrical and mechanical means; mechanical brake is used to hold the suspended cargo after disconnecting the driving motor from the supply. In modern hoisting electric drive systems, in addition to mechanical braking, electric braking is also used. Electric braking...

Dynamic collaborative driving involves the motion coordination of multiple vehicles using shared information from vehicles instrumented to perceive their surroundings in order to improve road usage and safety. A basic requirement of any vehicle participating in dynamic collaborative driving is longitudinal control. Without this capability, higher-level coordination is not possible. Each vehicle...

The difference in response to electric and hydraulic braking causes sudden changes torque during mode switching. An electro-hydraulic composite system’s dynamic coordination control strategy is proposed under switching conditions. By establishing the model of system (EHB), key factors affecting speed EHB are analyzed, fuzzy controller for pressure regulation brake wheel cylinder designed. At sa...
