Various methods have been utilized for the cooperative tasking of unmanned aerial vehicles (UAVs), with the genetic algorithm (GA) being a technique that has proven to be versatile and effective for this use. The design and implementation of a GA is both an art and a science that brings together creativity, theoretical foundations and engineering. The focus of this paper is to show how the fitness...
In China, a variety of non-motor vehicles (NM-Vehicle) exist on the road in recent years, some are similar to pedestrian, others are similar to motor vehicle (M-vehicle) in monitor video, which brings a great number of trouble to policeman when case tracking. In this paper, we proposed a traffic object classification pipeline based on state-of-the-art deep convolutional neural networks (CNNs).Unfortunately,...
The operation of electric vehicles in cold weather is a concern, but the precise nature of the impact on travel range and energy consumption is not well characterized. The Chevrolet Volt, a commercially-available plug-in hybrid electric vehicle (PHEV) was driven-to-depletion across a broad range of temperatures as occur naturally in Winnipeg, Canada, due to its climate. Results conform to a simple...
Metaphors help create realities for us, especially social realities. A metaphor influences behavior; to attract and/or divide. Metaphors for education provide symbolic representations of what we intend in education; insight into the philosophy that underlines both how we educate, and what we are trying to educate. E.g., "Education as a journey" conveys a different meaning and intention than...
Uncontrolled charging is known to cause problems for the distributed power network even if only 10% of cars are powered by electric, so a charging system that prevents such problems will become necessary as they increase in popularity. Electric vehicle charging regimes that can provide the charge required by the user whilst supporting the grid and protecting battery health are required and are described...
Recent models of hybrid vehicles and electric vehicles include traction motors with increasing capacity for rotation speed. Therefore, high-speed testing equipment suitable for use with traction motors and motor components is required in automotive research and development. Induction motors (IMs) with oil-cooling are suitable motors for testing equipment. Solutions for some drawbacks of high-speed...
This paper discusses on an experimental platform of an electromechanical simulator able to reproduce the power flows between a railway vehicle and the power supply system. The platform consists of an scaled-down system. It represents an urban DC railway systems in normal and extraordinary operating conditions. It is equipped with hardware and software components, suitable for testing mechanical moving,...
The validation and verification of cognitive skills of highly automated vehicles is an important milestone for legal and public acceptance of advanced driver assistance systems (ADAS). In this paper, we present an innovative data-driven method in order to create critical traffic situations from recorded sensor data. This concept is completely contrary to previous approaches using parametrizable simulation...
Systems Modeling Language (SysML) is used to capture systems design as descriptive and analytical system models, which relate text-based requirements to the system design model and provide an infrastructure to support analysis and verification. However, SysML is not a methodology, nor a method. This opens-up discussions of how to utilize SysML provided infrastructure to successfully achieve analysis...
The decreasing cost of radar and camera sensory technology has established advanced driver assistance systems (ADAS) to the standard equipment of modern vehicles. ADAS employ semi-autonomous interventions in longitudinal (e.g., adaptive cruise control, ACC) and lateral (e.g., lane-keeping aid, LKA) direction. ACC and LKA constitute the milestones of ADAS technology and have shown to correspondingly...
In a suburb of Bristol, in western England, not far from the Welsh border, a band of engineers are building a machine that they hope will make the biggest jump in the centurylong history of the official world land-speed record, taking it from a smidgen above the speed of sound to 1,600 kilometers (1,000 miles) per hour. That’s roughly the cruising speed of a fighter aircraft, but it’s considerably...
The paper describes the challenges of testing high voltage systems of modern electric and hybrid vehicles for electromagnetic compatibility (EMC). It introduces a new test set-up to assure EMC testing satisfying the relevant standards and specifications, while the system operates in its real condition. This set-up is already introduced in the international standard committee and is described in a...
Run-off test is performed in factory for first few limited production build machines. It verifies all the machine functions possible. The Virtual Vehicle Run-off test is new approach for automation test to perform first level product verification and validation in virtual environment to produce higher quality and productivity. Virtual Vehicle Run-off test helps to perform software PV&V in short...
This paper presents the methodology and utility of an HEV plant model using Matlab-Simulink for testing the HCU (Hybrid control Unit) logics in dSPACE Hardware-in-loop environment. It also describes how requirements related to Hybrid Controller testing are addressed using the subject plant model. It further discuss about the requirements for Inputs to hybrid controller that are modeled in close loop...
This paper would detail a novel and Frugal Embedded Software Development Methodology, accelerates the embedded software development for Instrument Clusters and Load Centers application. The Software modules for various features are perceived as modular and re-usable blocks. The development process is completely automated using a configurable framework. This method significantly reduces the overall...
Electronic controller unit (ECU) used for controlling sub-systems of complex real life applications like automotive vehicles can pose several challenges. Many times one needs to plan development and testing of controller, when the end vehicle is also under development and hence not available. In such case, hardware in the loop (HIL) approach for testing such controllers emulates the external application...
The Traditional way of embedded software testing follows a "V" cycle approach. This has multiple phases. Left side of the "V" represents Model in Loop and Software in Loop phase. Whereas the right side of the "V "represents Hardware in Loop and Vehicle in Loop phases. Ideally all the phases has its own importance and value addition in the world of embedded software Testing...
Light detection and ranging (LIDAR) scanners are essential components of intelligent vehicles capable of autonomous travel. Obstacle detection functions of autonomous vehicles require very low failure rates. With the increasing number of autonomous vehicles equipped with LIDAR scanners to detect and avoid obstacles and navigate safely through the environment, the probability of mutual interference...
High-power, bidirectional DC/DC converters are widely used in electric vehicles. As vehicle volumes increase, the robust and efficient testing of these converters will be key to high reliability and low cost. A highly configurable, closed-loop, regenerative burn-in test system is presented here that reduces power supply and load requirements to less than 1/10th of those required for conventional test...
Development and testing of novel Advanced Driver Assistance Systems (ADASs) based on Vehicle-2-X (V2X) communication is often supported by simulations. However, simulation models for Vehicular Ad Hoc Networks (VANETs) can easily become very complex due to the diverse set of involved components such as vehicle mobility, radio propagation, network protocols and application behavior. Therefore, we present...
