View of Chassis Without Top Body…..………………………………………………………………………….20 UNIVERSITY OF CINCINNATI Date: 8-Nov-2010 I, Kovid Mathur , hereby submit this original work as part of the requirements for the degree of: Master of Science in Mechanical Engineering It is entitled: Conversion of a Hybrid Electric Vehicle to Drive by Wire Status Student Signature: Kovid Mathur This work and its defense approved by: Committee Chair: Manish Kumar, PhD Manish Kumar, PhD Ernest Hall, PhD Ernest Hall, PhD Janet Dong, PhD Janet Dong, PhD 11/11/2010 1,200 Conversion of a Hybrid Electric Vehicle to Drive by Wire Status A thesis submitted to the Division of Research and Advanced Studies of the University of Cincinnati In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE In the Department of Mechanical Engineering of the College of Engineering 2010 By Kovid Mathur Bachelor of Engineering (Mechanical Engineering) Visvesvaraya Technological University, 2005 Committee Chair: Dr Manish Kumar Abstract With advancements in the automotive driving and safety technology the new age is looking to redefine transportation as we know it. The thrust area of study at the Center for Robotics Research at University of Cincinnati is building technology for autonomous vehicles and it has made considerable advancements over the years to building the future car. In summer 2006, Defense Advanced Research Projects Agency announced the third Grand Challenge which would feature ground vehicles executing “simulating military supply missions safely and effectively in a mock urban area”. The center entered the competition with a team of students and researchers to achieve this goal with generous contributions from Tank Automotive Research Development and Engineering Center (TARDEC), Applied Research Associates Inc (ARA) and the University of Cincinnati amongst others. An all terrain hybrid electric vehicle built by Cal Motors as an economical non tactical base transport vehicle was used as the competition entry, which was donated as per a Co-operative Research and Development Agreement (CRADA). This thesis presents the drive by wire solution along with the custom changes which were made on the vehicle in order to put the till now theories into practice. The design solution introduced control of linear actuators by more responsive and energy efficient servo motors which were driven by a Galil™ motion controller. Each axis of the controller was responsible for the control of electronic braking, steering and speed control systems respectively. The process involved some metal fabrication to incorporate the positioning of components for improved space usage and definite mounting, after which the iii systems were calibrated for optimum functioning. A series-hybrid approach was introduced for the ATV to provide longer hours of operation. Before the vehicle was allowed to ply on city streets it was brought to Ohio state law standards and in addition underwent a thousand mile durability test. The result of the research and development was a robust and effective system which could control by wire the all terrain vehicle (ATV) and met all primary goals of the project. iv v Acknowledgement My thesis work at the University of Cincinnati is the amalgamation of many people’s effort all through my life.

Dorrell3 Abstract An X-by-wire chassis can improve the kinematic characteristics of human-vehicle closed-loop system and thus active safety especially under emergency scenarios via enabling chassis coordinated control. This paper aims to provide a complete and systematic survey on chassis coordinated control methods for full X-by-wire vehicles, with the primary goal of summarizing recent reserch advancements and stimulating innovative thoughts. Driving condition identifca- tion including driver’s operation intention, critical vehicle states and road adhesion condition and integrated control of X-by-wire chassis subsystems constitute the main framework of a chassis coordinated control scheme. Under steer- ing and braking maneuvers, diferent driving condition identifcation methods are described in this paper. These are the trigger conditions and the basis for the implementation of chassis coordinated control. For the vehicles equipped with steering-by-wire, braking-by-wire and/or wire-controlled-suspension systems, state-of-the-art chassis coordi- nated control methods are reviewed including the coordination of any two or three chassis subsystems. Finally, the development trends are discussed. Keywords: X-by-wire systems, Chassis coordinated control,

  • The Design of a Controller for the Steer-By-Wire System∗
    896 The Design of a Controller for the Steer-by-Wire System∗ Se-Wook OH∗∗, Ho-Chol CHAE∗∗∗, Seok-Chan YUN∗∗ and Chang-Soo HAN∗∗∗∗ Drive-by-Wire (DBW) technologies improve conventional vehicle performance and a Steer-by-Wire (SBW) system is one of the DBW technologies. The control algorithm of the SBW system was designed in this paper. To verify the control algorithm, the SBW system is modeled using the bond graph method. The first aim of the control algorithm is controlling the steering wheel assist motor to make the real vehicle’s steering feel and for a vehicle designer to adjust the steering feel as he finds necessary. Therefore, torque map is designed to determine the steering wheel reactive torque. The second aim is controlling the front wheel assist motor to improve vehicle’s maneuverability and stability by using understeer and oversteer propensity of a vehicle. Furthermore, high performance control algorithm is proposed in this paper and Active Roll Stability Control (ARSC) method is designed as one of the high performance control algorithm. Key Words: Steer-by-Wire, Drive-by-Wire, Torque Map, Steering Feel, Active Roll Stabil- ity Control a vehicle’s weight by reducing the number of necessary 1.

Never disconnect the battery or the PCM while the ignition is turned “ON” 2. Never short any wires in the wiring harness to ground (with the exception to the ground wires) this can cause damage to the PCM. 3. A Multi-meter with a minimum of 10-Mohm resistance is required for test circuits. Do not back probe wires, this can lead to permanent wire damage. Requirements: 1. All Vortec engines require VATS to be removed from the PCM. If the system is not removed from the PCM the engine will NOT start. 2. Vortec engine harness utilizes two oxygen sensors on each side of the engine, one before and after the catalytic converter. The rear O2 sensors (after the catalytic converter) are NOT used. 3. All Vortec engines utilize an EGR, Air Pump, and CCP features for emission control, this harness does not include provisions for EGR, Air Pump, and CCP are not necessary for engine operation. PCM programing may be necessary to avoid storing a Diagnostic Trouble Codes (DTC) for the absence of emission equipment 4. It is recommended that you use a VSS when using a T56 or nonelectric transmission (TH350, TH400, Powerglide, 700R4, etc.).

In Proceedings of the 2019 IEEE Eurasia Conference on IOT, Communication and Engineering, Yunlin, Taiwan, 3–6 October 2019. Received: 31 December 2019; Accepted: 20 February 2020; Published: 23 February 2020 Abstract: This research mainly aims at the construction of the novel acceleration pedal, the brake pedal and the steering system by mechanical designs and mechatronics technologies, an approach of which is rarely seen in Taiwan. Three highlights can be addressed: 1. The original steering parts were removed with the fault tolerance design being implemented so that the basic steering function can still remain in case of the function failure of the control system. 2. A larger steering angle of the front wheels in response to a specific rotated angle of the steering wheel is devised when cornering or parking at low speed in interest of drivability, while a smaller one is designed at high speed in favor of driving stability. 3. The operating patterns of the throttle, brake, and steering wheel can be customized in accordance with various driving environments and drivers’ requirements using the self-developed software.
