The Simulation of Automotive Braking Energy Recovery System based on AMESim

Abstract

Based on AMESim, this paper focuses on the modeling and simulation of a particular bus. Set-ting a certain speed for the bus, and then take braking. Through analyzing the process of braking energy recov-ery and launching of the bus, a series of simulation curves are obtained. And then, it is concluded that the influence of the filling pressure of the accumulator and the displace- ment of the hydraulic pump on the braking performance are similar, and the volume of the accumu- lator have less effect on the braking performance. Instruction Braking energy recovery is a form of energy efficient and environmentally friendly way of brak- ing which is different from the traditional friction braking. It makes a part of the mechanical energy converted to other forms of energy, through the energy conversion device which connected to the drive axle. And then, the energy will be stored in an energy storage device. During the vehicle start- ing, acceleration, uphill, this part of energy as auxiliary power supply released and returned to drive axle. The working process of the braking energy recovery system itself is the process of the auto- mobile braking deceleration, so the use of this system will reduce the use of traditional braking sys- tem. It is to say, the use of Braking Energy Recovery System can improve the power performance and fuel economy of the vehicle, and can reduce the emissions of pollutants and the wear and tear of the braking system.
