The goal of the SAE ORAV RAI task force is to develop a shared framework and language for addressing the basic system functions and functional interfaces in the form of a reference architecture for automated vehicle to support the SAE levels of driving automation for on-road vehicles (e.g., J3016). While the final architecture may eventually support conformance testing for component level interoperability the deliverable for this task force (i.e., white paper) will describe of how requirements will be achieved through a model-based representation of reusable patterns of activity, functionality, information/data flows, and scenarios of sequenced responses to time events. To achieve this goal, the task force will conceptualize and define a reference architecture that contains modular software (and possibly hardware) components based on standardized interfaces.

Abstract To increase the range of a Battery Electric Vehicle (BEV), a lot of ideas have been proposed. A prominent one among them is the Battery swapping methodology or Rapid Battery Interchange (RBI), where standardized batteries can easily be removed from the BEV and replaced with recharged batteries quickly. The feasibility of this methodology has been highly debated and contested. This paper studies the feasibility of a very popular distribution and maintenance network currently used for LPG distribution in India, to be applied to battery distribution used across different makes and models of BEVs. In India, 33.6 million households subscribe to LPG Cylinders for domestic cooking usage. These standard sized (14.2Kg) cylinders are refilled and redistributed via multiple public sector and private companies.

Abstract Hybrid Electric Vehicle (HEV) Controls Development is an important aspect to realize the goals of Powertrain Electrification i.e. fuel economy and emission improvement. Keeping that in mind, development engineers need to formulate numerous control strategies. Once the control strategy is evaluated and frozen, it typically does not change from one vehicle model application to another. However, it may happen that Electronic Control Unit (ECU) manufacturer may change depending on the sourcing strategy. Therefore, in order to maintain uniformity, it may be required to compare control strategy of a finished ECU product frozen for one model application to be compared with new ECU sourced through another manufacturer. This paper discusses a methodology to compare control strategy of two ECU’s sourced from different ECU manufacturers with identical control requirements.

Abstract Battery modeling is of major concern going forward for Hybrid Electric Vehicle (HEV) and Electric vehicle (EV) modeling. The major issue lies in characterizing the battery power, Charge acceptance and reaction to sudden load changes (transient behavior) in relation to battery’s State of Charge (SOC). In particular modeling the battery is challenging task as it requires a lot of test data to understand and validate modeled chemical and electrical characteristics in various operating conditions. Hence, the one of the ways of simulating Battery based Hybrid System is to use battery Hardware-in-the-Loop Simulation (HILS) or simply known as Battery-in-Loop (BIL). With this approach hybrid vehicle or more precisely battery management system (BMS) development time and cost can be significantly reduced by eliminating the detailed battery modeling. To understand the effectiveness of this approach, Battery Hardware-in-Loop test setup was developed.

Abstract The relevance of Hybrid electrical vehicle (HEV) / Electrical vehicles (EV) is seen as never before due to global call for the reduction in carbon foot print. In such a scenario HEV/EV has a greater role to play. But as years pass by there are still a few technological challenges which makes the automotive world a bit skeptical about the immediate and complete take over by HEV/EV. As of now Li-ion cells are the front runner as a favorite to various automotive OEM’s as the stored energy source. The average time required to charge a Li-ion based vehicle ranges from 4-6 hours [Table 1].This paper analyses different charging methods/configurations based on different approaches in literatures based on three critical parameters namely charging time, battery life and safety.

Abstract The constant mesh gearbox is the most adoptable transmission unit that is available in the current automotive market today because of the simple gear train design. This design features a driver operated clutch and a movable gear stick. Most automobile transmissions allow the driver to select different gear ratios at any time. But with the increased demand in the number of gear ratios for increased torque and speed, transmission unit is getting bigger and controlling them has become more complex. This paper identifies a new way of power flow in the gear box, resulting in availing more numbers of gear ratios with less number of gears from the existing unit. This paper also suggests the development of a electronic control system for the shifting of the gears for smooth operations.

Abstract In today’s fast moving vehicle scenario, road safety is of utmost importance. Many people have lost their lives while travelling, due to a road accident. So we should mitigate such accidents if we wish to travel safely. To cater this cause, we propose an adaptive steering controlled headlight setup. The system can be adopted in any type of four wheel vehicles/trucks or trailers etc. without being an economic burden on the end user. The notion of steering controlled headlight is not new, but its adaptability according to the steering turning angle is its novel part. A lot of companies have developed technologies that incorporate turn able headlight to better illuminate the path, but these technologies are quite expensive and continue to be distant from the majority of car owners. So we felt the need of developing a mechanism that incorporates few simple components like gears, linkages etc. and can be readily fitted onto any steering column without much of a design variations.

Abstract This paper describes the design methodology and algorithm development towards the design of an automatic external gear-shifting and clutch-actuation system for a sequential gearbox with the aim of providing the drivers with easier and an efficient means of shifting gears. Automatically actuated manual transmission system bridges the gap between automatic and manual transmissions which provides the advantages of both type of transmissions. This would ideally leads to faster shifting time and provide significant benefits in the form of electronic-aids like launch control and traction control. Removal of mechanical clutching would reduce fatigue and lead to ergonomic benefit. Based on the benchmarking performed on an easily available ready-to-install aftermarket alternative, options will be considered for the actuating mechanism and the most feasible will be used to develop a shifting system.

Abstract In laboratory car crash tests, Anthropomorphic Test Devices (ATD) are equipped with piezoresistive and resistive sensors for occupant injury assessment. Accelerometers are inertial transducers that convert acceleration into electrical output which can be easily recorded by a Data Acquisition System (DAS). For an accelerometer, this electrical output mainly depends upon subjected acceleration, sensitivity of the accelerometer, excitation voltage and gain provided. Before use in testing, accelerometers are calibrated at a standard excitation (manufacturer decided) voltage to determine characteristics like Sensitivity, Sensitivity per unit excitation voltage, Zero Measurand Output (ZMO), Transverse Sensitivity etc. It is observed that these characteristics are highly dependent on the excitation voltage. In testing, due to limitations of DAS and/or other unwanted noise in the excitation voltage, these accelerometers are sometimes used at a different excitation voltage.

Abstract This paper suggests an Intelligent Control Algorithm for optimizing the charge and discharge of a battery pack used in a hybrid/electric vehicle. With precision control of voltage and current levels in secondary batteries, high performance and greater battery life can be achieved and the problems of overcharging and over discharging in batteries can be avoided. It uses cell isolation system, which controls the number of cells required specifically for an instantaneous load condition, thus reducing the overall internal resistance of battery pack, hence reduces losses due to heating.

Primary function of the inverter in an Electric or Hybrid Electric vehicle (EV/HEV) is to generate required AC voltage from high voltage battery to drive Electrical machine (EM). Being part of power-train of the vehicle, inverters (or hybrid control units (HCU)) are safety related electronic control units (ECU) due to the severity of the accidents/incidents that could result if the ECU is not functional as intended. Therefore it is necessary to develop the inverter in accordance with applicable safety standards. The standard ISO 26262 in particular addresses the complete development cycle of safety related automotive products. OEMs now mandate the strict adherence to ISO26262 standard for such ECUs. This paper describes how safety principles are realized in the hardware modules of inverter, which are responsible for the functional safety adherence.
