“…According to BOCKER (2013), the estimate of the potential of energy storage by regenerative braking is around 10% in real applications. XU et al (2011) implemented a system of regenerative braking in an electric vehicle using fuzzy logic and achieved an improvement in the autonomy of 25.7% experimentally. However, a lot of the mechanized agricultural operations are maneveurs operations that require low speeds and also constant speeds, presenting; therefore, so little acceleration and deceleration, in addition to undergoing through a lot of tires friction on the ground and additional forces of agricultural implements.…”

This paper presents the main applications of electric vehicles in rural areas, pointing out the trends and challenges for the future. Technological conditions and difficulties faced by the industry for a wide dissemination of this technology are discussed. The paper described the main researches with proposals to overcome the problems of implementing electric tractors, as supply and electricity storage. Technical and economic comparisons between conventional internal combustion tractors and electric tractors are also presented and discussed. The paper showed the existence of barriers to the implementation of electric vehicles in rural areas, as well as the need for batteries technological evolution, which have high costs and for that reason they are very heavy for these purposes, but there are already systems that can be applied to minimize dependence of fossil fuels in this sector and increase the use of sustainable energy.

“…To employ both two brake systems, the architecture of the brake system needs to be changed instead of conventional construction. There are two techniques to coordinate the regenerative torque of the motor and friction torque of the hydraulic unit: parallel and series (7) . In order to recover kinetic energy as much as possible during braking, the hydraulic brake force prefers not to operate until regenerative brake force reaches its maximum availability.…”

Integrated Slip-Based Torque Control of Antilock Braking System for In-Wheel Motor Electric Vehicle

et al. 2014

In electric vehicles (EVs), cooperative control between a regenerative brake system (RBS) and the conventional hydraulic brake system (HBS) enhances the brake performance and energy regeneration. This paper presents an integrated antilock braking control system based on estimating the wheel slip to improve the anti-slip performance of a four wheel drive in-wheel motor EV. A novel anti-slip control method for regenerative braking was developed and integrated with a hydraulic antilock braking system (ABS) according to the logic threshold concept. When combined with the features of driving motors, the proposed method can improve the brake performance under slip conditions. Comparative simulations showed the proposed control approach provided a more effective antilock braking performance than the conventional ABS.

“…However, the conventional friction braking system must be retained and works together with the regenerative braking system since the regenerative braking torque is limited by many factors, such as the motor speed, the state of charge (SOC) and temperature of the battery [2]. This prompts the development and investigation of regenerative braking strategies and control methods during normal braking events and emergency braking events [3,4].…”

Performance Evaluation of an Anti-Lock Braking System for Electric Vehicles with a Fuzzy Sliding Mode Controller

Traditional friction braking torque and motor braking torque can be used in braking for electric vehicles (EVs). A sliding mode controller (SMC) based on the exponential reaching law for the anti-lock braking system (ABS) is developed to maintain the optimal slip value. Parameter optimizing is applied to the reaching law by fuzzy logic control (FLC). A regenerative braking algorithm, in which the motor torque is taken full advantage of, is adopted to distribute the braking force between the motor braking and the hydraulic braking. Simulations were carried out with Matlab/Simulink. By comparing with a conventional Bang-bang ABS controller, braking stability and passenger comfort is improved with the proposed SMC controller, and the chatting phenomenon is reduced effectively with the parameter optimizing by FLC. With the increasing proportion of the motor braking torque, the tracking of the slip ratio is more rapid and accurate. Furthermore, the braking distance is shortened and the conversion energy is enhanced.
