Investigation on Different Driving Cycle and Scenarios Considering the Autonomous Electric Vehicles

Abstract

This study presents a series of analyzes considering the traction and steering demands of an autonomous electric vehicle (AEV) as a shuttle. The considered analyzes in here are dealt with as driving cycle (DC) and driving scenarios (DS) to assess the traction and steering performance of the AEV. The aim of this study is to evaluate the issues such as over engineering for AEV traction and steering motor requirements on a certain route by comparatively analyzing traditional and dynamic calculation under the DC and DS. Therefore, DC and DS in the lit-erature are evaluated in terms of different applications, optimization techniques, generation algorithm, parametric characterization, e-motor type etc. Afterwards, NEDC, US06, WLTC, Double Lane Change (DLC), Constant Radius (CR) and Slowly Increase Steer (SIS) are determined. Then, they are arranged according to the vehicle-specific limits on an electric golf car. The modified DCs and DSs are run on the dynamic model of the vehicle. In the performed analysis, the parame-ters such as reference trajectory tracking, yaw angle, tractive and steering forces, lateral and longitudinal displacement-acceleration, steering and traction motor power–speed-torque are investigated. And the obtained results are evaluated by comparing the traditional calculation results.

Analysis of the operating characteristics of hydrogen PEM fuel cell and battery onelectric vehicle in different driving cycles

“…With the PEM fuel cell, it not only provides energy directly to the electric motor throughout the cycles, but also the battery was charged. In addition, in these three driving cycles, the PEM fuel cell stack showed the best performance in the FTP75 cycle as it had lower instantaneous acceleration and lower maximum speeds ( 52 ). With PEM fuel cell, in the FTP 75, NEDC, and WLTC tests, a total of 4224.23, 19386.9, and 13596.9 kW of energy were stored by charging the battery, respectively.…”
