Experimental Investigation of Electric Vehicle Performance and Energy Consumption on Chassis Dynamometer Using Drive Cycle Analysis

SAE International Journal of Sustainable Transportation, Energy, Environment, & Policy

Indian Institute of Petroleum CSIR, India-Robindro Lairenlakpam
  • Journal Article
  • 13-01-01-0002
Published 2019-12-02 by SAE International in United States
This article reports an experimental study carried out to investigate the vehicle performance and energy consumption (EC) of an electric vehicle (EV) on three different driving cycles using drive cycle analysis. The driving cycles are the Indian Driving Cycle (IDC), Modified Indian Driving Cycle (MIDC) and Worldwide harmonized Light vehicles Test Cycle (WLTC). A new prototype electric powertrain was developed using an indigenous three-phase induction motor (3PIM), Li-ion battery (LiB) pack, vector motor controller, and newly developed mechanical parts. In this research work, a pollution-causing gasoline car (Maruti Zen) was converted into an EV by using the new powertrain. The EV conversion vehicle was used as the test vehicle. After the removal of the Internal Combustion Engine (ICE) the new powertrain was integrated with the vehicle’s gearbox (GB) system which was configured on a single motor, fixed gear configuration having a gear ratio of 1.28:1. The EV performance tests were carried out on the chassis dynamometer that followed the driving cycles. The maximum speed test showed a top speed of 64 km/h for the EV.…

Performance Specifications for a Midsize Male Pedestrian Research Dummy

Human Biomechanics and Simulations Standards Committee
  • Ground Vehicle Standard
  • J2782_201911
  • Current
Published 2019-11-26 by SAE International in United States

While it is recognized that collisions involve pedestrians of all sizes, this Information Report addresses performance specifications for a midsize adult male research dummy. This approach stems from the greater knowledge of biomechanics and existing dummy technologies for the midsize male relative to other adult sizes and children. While not the initial objective, it is envisioned that additional performance specifications for other sizes of pedestrian research dummies will be developed in the future based on accepted scaling procedures.

Determining the State Of Health [SOH] of Li Ion cell

Sushant Manohar Mutagekar
  • Technical Paper
  • 2019-28-2579
Published 2019-11-21 by SAE International in United States
“NuGen Mobility Summit-2019” Paper Title : Determining the State Of Health [SOH] of Li Ion cell Authors: Sushant Mutagekar, Ashok Jhunjhunwala, Prabhjot Kaur Objective Cells age with life. This aging is dependant on various factors like charging/discharging rates, DOD of operation and operating temperature. As the cell ages it undergoes power fade (ability to deliver required power at particular State of Charge [SOC]) and capacity fade (the charge storage capacity of cell). In an Electric Vehicle it is important to know what power shall be demanded from a battery irrespective of what its current SOC is and number of cycles it has undergone. With minimal accuracy and less computational power, it is difficult for a Battery Management System [BMS] to accurately determine SOH; the paper proposes a a precise model that may help. Methodology To understand different cells aging at different conditions, an experiment was setup to simulate various conditions of a cell. • Cycling: Cells of different form factors were cycled continuously at different ambient temperatures, different discharge rates and Depth of discharges. •…

Seat Belt Dynamic Test Performance Sensitivity to Anchorage Location Tolerance of 50 mm

ICAT-Akshat Gupta
  • Technical Paper
  • 2019-28-2398
Published 2019-11-21 by SAE International in United States
Seat Belt Assemblies used in a vehicle are tested and certified as per ECE R16/ IS 15140 for its performance during dynamic test. During validation test, seat belt anchorages are set-up as per design condition. The tolerance provided in the regulation for each anchorage is 50mm. Also there is difference in actual anchorage location in a vehicle and design location. This tolerance and variation can affect the performance of seat belt during the test or actual car accident. This study shows the variation of seat belt performance when different combination of anchorage locations is used within 50 mm.

Trajectory Tracking Control for Autonomous Driving Vehicle with Obstacle Avoidance: Modeling, Simulation, and Performance Analysis

SAE International Journal of Connected and Automated Vehicles

China-Songxin Shi
Huazhong University of Science and Technology, China-Hefeng Zhan, Chaoran Lin, Qiangqiang Huang
  • Journal Article
  • 12-02-04-0014
Published 2019-11-19 by SAE International in United States
The external driving environment of an autonomous driving vehicle is complex and changeable. In this article, the trajectory tracking control with obstacle avoidance based on model predictive control was presented. Specifically, double-level control scheme by controlling the front steering angle was used in our research, and the double level is composed of the high level of model predictive controller for local trajectory planning and low level of model predictive controller for trajectory tracking. At high level, the local trajectory planner based on the point-mass model was designed. Then, at low level, the linear time-varying vehicle dynamics model was presented, and the trajectory tracking controller was proposed considering control variable, control increment, and output constraint. Finally, the trajectory tracking performance was tested in co-simulation environment with CarSim and Simulink, and the tracking errors were analyzed. Compared with the controller without a high level for local trajectory planning, this article indicates that the trajectory tracking controller has rather effective and efficient trajectory tracking performance during all conventional cases, which shows strong robustness to vehicle speed.
