Abstract: For the characteristics of full electric propulsion, a novel kind of brake-by-wire unit is designed for electric vehicle to improve braking performance. A comprehensive brake-by-wire system including this unit is set up after its structure and principle are introduced. Then, a multi-layer fuzzy controller is proposed to regulate decelerate and wheel slip rate, and an optimal regenerat...

An optimal Fractional Order PI λ D μ (FOPID) controller is designed for a full vehicle nonlinear active suspension system. The optimal values of FOPID controller parameters for minimizing the cost function are tuned using an Evolutionary Algorithm (EA), which offers an optimal solution to a multidimensional rough objective function. The fitness parameters of FOPID controller (proportional const...

This paper deals with the design of a brake caliper pressure controller for a conventional ABS/ESC system and the experimental validation of its tracking performances. The analysis of the hydraulic plant, carried out in Part I of this two-part study, is here utilized to develop the control algorithm for ABS digital electro-hydraulic valves. The control strategy is based on a Feedforward (FF) an...

In this manuscript, a control strategy for electric vehicles is developed to optimise the energy consumption while respecting constraints associated with both inter-vehicle safety and comfort, which challenge in typical optimal solution methodologies. Firstly, long-term using Pontryagin's Maximum Principle (PMP). Thereafter, obtained PMP used bound state space computationally tractable Dynamic ...

Accelerations and braking of vehicles can be measured and analyzed with different systems and software. In our case, we used the system G-Tech Pro Performance Meter RR w and Performance Analysis System Software (PASS). This system enables measurements of longitudinal accelerations, lateral accelerations and braking. PASS software has two options, the first is Drag Runs, which is designed for th...

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...

Regenerative braking is an effective approach for electric vehicles (EVs) to extend their driving range. A fuzzy-logic-based regenerative braking strategy (RBS) integrated with series regenerative braking is developed in this paper to advance the level of energy-savings. From the viewpoint of securing car stability in braking operations, the braking force distribution between the front and rear...

The purpose of this study was to investigate the effect of weighted jump squat training with and without eccentric braking. Twenty male subjects were divided into two groups (n = 10 per group), Non-Braking Group and Braking Group. The subjects were physically active, but not highly trained. The program for Non-Braking Group consisted of 6 sets of 6 repetitions of weighted jump squats without re...
