Avoiding Obstacles Safely at High Speed: An Optimal Control Approach for Driving Heavy Autonomous Ground Vehicles Close to their Dynamic Limits
June 22, 2016
by Paul N. Blumberg, PhD
No one who follows automotive news and technology trends can be unaware of the intense research and experimentation taking place related to vehicles that drive themselves, i.e., “Autonomous Vehicles.” Among other potential benefits, these vehicles offer the promise of increased safety on the nation’s roadways and personal mobility to those who are not able or do not wish to drive themselves.
The Society of Automotive Engineers has already developed Standard J3016 which describes six different levels of “driving automation” increasing from Level 0 - No Automation, to Level 5 - Full Automation. At Level 0, a human driver performs all driving tasks, even if assisted by warning or other momentary intervention systems. At Level 5, a system comprising sensors, actuators and control algorithms performs all driving tasks such as steering, braking, acceleration and monitoring the vehicle and roadway under all modes of driving. At Level 5, a human driver is no longer necessary.
NVIDIA deep learning software platform gets trio of big updates
June 20, 2016
NVIDIA announced three major updates for its deep learning software platform. NVIDIA DIGITS 4 introduces a new object detection workflow, enabling data scientists to train deep neural networks to find faces, pedestrians, traffic signs, vehicles and other objects in a sea of images. This workflow enables advanced deep learning solutions—such as tracking objects from satellite imagery, security and surveillance, advanced driver assistance systems and medical diagnostic screening.
When training a deep neural network, researchers must repeatedly tune various parameters to get high accuracy out of a trained model. DIGITS 4 can automatically train neural networks across a range of tuning parameters, significantly reducing the time required to arrive at the most accurate solution.

A novel method for energy efficient warmup of lithium-ion batteries from sub-zero temperatures using predictive control
June 06, 2016
by Paul N. Blumberg, PhD
Many of the machines and appliances that are in common use today require that their power be available immediately, regardless of adverse ambient conditions such as sub-zero temperatures. For example, on a 0 °F day, we expect to be able to start our cars or trucks, which may have cooled down to near ambient conditions, and proceed to use them in the same manner as if we were in more moderate climates. To accomplish this, engineers and scientists have worked hard to ensure that in extremely cold temperature environments, the engine oil does not become too viscous and that there are sufficient high volatility components in the fuel so that vaporization and ignition within the engine are possible on an almost instantaneous basis.
The same requirement holds true for battery-powered devices or vehicles. The Lithium-ion battery has emerged as the current “battery of choice” for automotive hybrid and electric vehicle applications. Over the last decade, significant improvements in its energy and power density have been made through research in all aspects of its fundamental electrochemistry and materials. Nevertheless, due to fundamental electrochemical factors, the availability of “instantaneous” power at temperatures below approximately 15 ˚F remains a challenge.
New Georgia Tech MPPI technique controls autonomous vehicles at edge of handling limits
May 24, 2016
Researchers from Georgia Tech’s Daniel Guggenheim School of Aerospace Engineering (AE) and the School of Interactive Computing (IC) have developed a new control technique for autonomous vehicles that can help keep a driverless vehicle under control as it maneuvers at the edge of its handling limits.
The Georgia Tech method—model predictive path integral control (MPPI) using covariance variable importance sampling—was developed specifically to address the non-linear dynamics involved in controlling a vehicle near its friction limits. The approach could help make self-driving cars of the future safer under hazardous road conditions. A paper covering this research was presented at the recent International Conference on Robotics and Automation (ICRA) in Stockholm, 16-21 May.
Audi A7 piloted driving concept “Jack” now driving more naturally
May 13, 2016
Audi’s latest version of its piloted driving research car, the Audi A7 concept “Jack,” has not only learned how to autonomously perform all of its driving maneuvers on the expressway, it has also learned how to show consideration for other road users.

UC Riverside reinforcement-learning-based real-time energy management system can improve PHEV efficiency by almost 12%
February 09, 2016
Researchers at the University of California, Riverside’s Bourns College of Engineering have demonstrated that a new, data-driven, reinforcement-learning-based, real-time energy management system (EMS) can improve the efficiency of current plug-in hybrid electric vehicles (PHEVs) by almost 12% compared to the standard, binary mode control strategy. The UCR EMS optimizes the power-split control in real time while learning the optimal decisions from historical driving cycles.
Further, the ~12% improvement does not factor in charging opportunities. An 8% fuel saving—again, compared to the standard binary mode EMS—can be achieved when charging opportunities are considered, the researchers said in a paper describing the system in the journal Transportation Research Record.

Audi’s production electric e-tron quattro may set a new standard for vehicle handling; advanced vehicle dynamics control
December 01, 2015
The production version of Audi’s battery electric e-tron quattro SUV (earlier post), due out in 2018, is an important vehicle for the brand, and especially for Audi of America, which is driving many of the requirements for the C-segment electric SUV. At the LA Auto Show, Audi of America President Scott Keogh said that the brand is targeting at least 25% of its US sales to be e-tron—i.e., plug-in hybrid or full electric—models by 2025. (Earlier post.)
He also observed, in a conversation on the eve of the LAAS, that if an automaker can launch a defining product, the game changes. Audi intends for the e-tron quattro to become such a defining product—an Audi electric SUV in the high-volume C-segment that is reasonably priced (in the luxury sector) and delivers longer range along with all the “known” benefits of electric drive: speedy acceleration, quiet, lower cost of fueling, and zero tailpipe emissions (as well as the high-value HOV sticker for some markets). But to make this a benchmark product, Audi intends to go further, leveraging the three-motor electric quattro powertrain through very advanced software controls to deliver a ride and handling experience not possible even in an all-wheel drive electric vehicle equipped with a torque vectoring differential mechanism (e.g., a Tesla).

HARMAN contributes open source software to Open AVB Project for low-latency, real-time automotive Ethernet
November 03, 2015
HARMAN has made an open source software contribution to the Open AVB project to help drive the adoption of Ethernet AVB/TSN (Audio Video Bridging/Time Sensitive Networking) in automotive, consumer, pro audio/video and industrial markets. In AVB/TSN, the maximum latency is deterministic and thus supports low-latency applications from live A/V to machine control.
Legacy Ethernet uses “best effort delivery”—i.e., data traffic flow is indeterminate, and intervening traffic can delay a data stream. Because of this uncertainty on receiving a stream packet, the receivers in legacy systems typically employ large buffers so as not to underflow, which would result in an audible click on an audio stream or loss of critical control information in a control stream.
New, faster cutting-plane optimization algorithm
October 23, 2015
The theory—and sometimes the implementation—of control systems relies heavily on optimization (e.g., earlier post)—as do many other aspects of engineering and design (e.g., earlier post). At the IEEE Symposium on Foundations of Computer Science, a trio of present and past MIT graduate students won a best-student-paper award for a new general-purpose algorithm for solving optimization problems.
The new “cutting-plane” method algorithm improves on the running time of its most efficient predecessor, and the researchers offer some reason to think that they may have reached the theoretical limit. They also present a new method for applying their general algorithm to specific problems, which efficiency gains of several orders of magnitude.

The car has become the most computationally complex high-tech device with which the vast majority of consumers will ever come into contact—let alone own. The car has also become a focal point for the development of innovative and entrepreneurial technologies, services and business models designed to enhance and evolve not only the basic efficiency of vehicles, but also the way in which they are used alone and as a part of a larger multi-modal transportation eco-system.
There have been and continue to be a number of market drivers forcing this evolution: concerns over health effects, congestion, consumption of petroleum-based fuels, climate change, an ever more rapidly increasing population and what appears to be an inexorable movement toward large-scale urbanization. The auto industry has known for a long time that business-as-usual was literally unsustainable.

New efficient hybrid optimization control method for diesel engine emissions and performance
October 19, 2015
Researchers at Iowa State have developed a new hybrid optimization control method to improve diesel engine emissions and performance. As reported in a paper in the International Journal of Engine Research, the hybrid method, which combines both particle swarm optimization (PSO) and genetic algorithm (GA) methods was able to locate a narrow window of operation which showed 27% lower NOx emissions and 60% lower particulate matter emissions than a standard PSO method.
The hybrid method was also able to locate the improvements using similar dynamometer time, indicating that the hybrid method is more efficient and more effective, the researchers said.
ORNL researcher proposes solution for online optimization of power management in HEVs/PHEVs and for different drivers
October 12, 2015
Dr. Andreas Malikopoulos at Oak Ridge National Laboratory (ORNL) has developed a solution for the online optimization of power management in parallel HEVs/PHEVs and for any different driver (i.e., for different driving styles). A paper on his work is published in IEEE Transactions on Control Systems Technology.
There has been a great deal of work done since the late 1990s on the optimization of power management control—i.e., the optimal distribution of power demanded by the driver to the available subsystems of combustion engine, motor, generator and battery—in parallel HEVs. Despite that significant body of work, Malikopoulos notes, deriving online an optimal solution for different driving styles still remains a challenging control problem.

Volkswagen: new EU 6 diesels clear of software cheat, but up to 11M EA189 diesels worldwide affected
September 22, 2015
In a statement issued this morning, Volkswagen AG said that new vehicles from the Volkswagen Group with EU 6 diesel engines currently available in the European Union comply with legal requirements and environmental standards. The engine control software in those vehicles does not affect handling, consumption or emissions, the company said.
Although the engine management software that enabled the cheating on NOx targets (earlier post) is installed in other Volkswagen Group vehicles with diesel engines, the company added, for the majority of those engines the software does not have any effect. However, the software “discrepancies” do relate to vehicles with the Type EA189 2.0-liter diesel engines—involving some eleven million vehicles worldwide. (Earlier post.)

The cars clocked 750 hours of drive time and gathered 150 million data points, correlated with data from EPA stationary measurement sites. EPA provided scientific expertise in study design and instrument operations as part of a Cooperative Research and Development Agreement (CRADA) with Aclima.
Roland Berger study explores need for consolidation in vehicle electronic architectures
In a new study, Roland Berger Strategy Consultants explores the strategy of module consolidation as a solution for the feature- and function-driven increasing complexity of vehicle electronic architectures.
Consumers increasingly expect the latest and greatest in electronics and safety when purchasing a car, regardless of type. Whether it’s an instrument cluster with a graphics rich, fully reconfigurable display or a lane departure warning system, a tremendous amount of processing power and electronic communication is required. The current approach to adding these features to vehicle’s electric/electronic (E/E) architectures is generally “ad-hoc”—i.e., simply adding a new ECU every time a new vehicle feature requires processing power. This has resulted in vehicles with as many as 100 ECUs and more than 100 million lines of code in ultra-luxury cars.
