A cybersecurity testbed for connected and autonomous vehicles

Ohio State University-Matthew Appel, Pradeep Sharma Oruganti, Qadeer Ahmed, Jaxon Wilkerson, Rubanraj Sekar

Connectivity and autonomy in vehicles promise improved efficiency, safety and comfort. The increasing use of embedded systems and the cyber element bring with them many challenges regarding cyberattacks which can seriously compromise driver and passenger safety. Beyond penetration testing, assessment of the security vulnerabilities of a component must be done through the design phase of its life cycle. This paper describes the development of a benchtop testbed which allows for the safety and security evaluations of components with all capabilities from Model-in-loop to Software-in-loop to Hardware-in-loop testing. Environment simulation is obtained using the AV simulator, CARLA which provides realistic scenarios and sensor information such as Radar, Lidar etc. MATLAB runs the vehicle, powertrain and control models of the vehicle allowing for the implementation and testing of realistic models. Real-time simulation and connectivity with external components is obtained through the use of a Speedgoat real-time machine. A fluid integration between the multiple software parts are realized using Robotic-Operating-System (ROS). Communication with external hardware can be achieved through different network protocols such as CAN, LIN, SAE J1939…

Non-contact Overload Vehicle Recognition by Vehicle to Roadside Unit

To be published on 2020-04-14 by SAE International in United States
Overloading of vehicles will affect the safety of driving, aggravate the wear of automobile brake system and make the braking distance of overloaded vehicles too long. Secondly, when the vehicle is overloaded, due to the increase of load, the stress will exceed the allowable value, which will cause early wear and damage of the parts, resulting in a decrease in the reliability of the service life of the vehicle. At present, for the detection of overloaded vehicles, most areas still adopt the method of static overload detection station or adopt the monitoring mode of traditional manual watching by installing video monitoring system. It is not efficient at all. To solve these problems, a overload vehicle detection system based on V2R (Vehicle to Roadside Unit) is developed. The system collects engine speed, engine torque and other signals through the CAN (Controller Area Network), and uses DSRC (Dedicated Short Range Communications) to directly transmit the vehicle data information to the roadside detection unit. As the speed signal collected by CAN is detected by wheel speed sensor, and…

Understanding the Implications of 5G Cellular

  • Magazine Article
  • TBMG-36152
Published 2020-03-01 by Tech Briefs Media Group in United States

The hype machine is in full swing with the latest standard in mobile telephony — 5G. This is the fifth generation of wireless, mobile broadband communications. It should not be confused with 5 GHz Wi-Fi, which is sometimes erroneously referenced as 5G. This 5G is a whole new ballgame and promises to be a revolution in how we live our daily lives — not merely an evolution of versions past.

Wireless System Powers Devices Inside the Body

  • Magazine Article
  • TBMG-36169
Published 2020-03-01 by Tech Briefs Media Group in United States

In the brain, implantable electrodes that deliver an electrical current are used for a technique known as deep brain stimulation, which is often used to treat Parkinson’s disease or epilepsy. These electrodes are now controlled by a pacemaker-like device implanted under the skin, which could be eliminated if wireless power is used. Wireless brain implants could also help deliver light to stimulate or inhibit neuron activity through optogenetics, which so far has not been adapted for use in humans but could be useful for treating many neurological disorders.

For Power-Efficient Wireless Sensing, Start with Analog Processing

  • Magazine Article
  • TBMG-36150
Published 2020-03-01 by Tech Briefs Media Group in United States

It seems like new applications for wireless sensors are appearing nearly every day. Two of the biggest growth areas are wake-word-driven systems like Alexa or Google and remote vibration monitoring of industrial machinery. Vibration monitoring provides useful information about the machinery, either in real time — condition monitoring; or to predict defects 60 or 90 days in advance — predictive maintenance.

Harness Wireless IoT Sensors for Integrated Building Management

  • Magazine Article
  • TBMG-36153
Published 2020-03-01 by Tech Briefs Media Group in United States

The Internet of Things (IoT) is proving its impact on the real estate sector. According to forecasts, building automation will lead the growth rate of connected devices in 2020. Smart building endpoints are expected to grow by 42 percent next year, reaching the staggering number of 440 million. Facility managers, real estate owners, as well as commercial and industrial businesses are looking to deploy IoT for its multifold benefits — from augmenting building efficiency and lowering costs, to improving tenants’ experience. These exciting opportunities come from granular insights into disparate aspects of building operations — all accessible from a centralized management platform.

Research on the Enhanced ADAS Functions with Modular Design Based on 5G-V2X Technology

Guang Zhou Automobile Research & Development Center (GAC-Guan Jiayi, Zhong Guoqi
Intelligent Driving Department, Automotive Engineering Insti-Jin Pingfan
  • Technical Paper
  • 2020-01-5026
Published 2020-02-24 by SAE International in United States
This paper will mainly discuss the effect of the combination of the 5th generation wireless systems - Vehicle to Everything (5G-V2X) technology an Advanced Driver Assistance Systems (ADAS) functions. With the promotion and popularization of 5G technology with high bandwidth and bottom delay, V2X has been able to quickly and safely transmit more information to target vehicles in need in the field of automatic driving. Traditional ADAS functions development has been carried out for decades, but there are still many unsolvable problems in perception and decision-making. In this paper, V2X technology is introduced into the auxiliary driving functions of L0-L3 stage by using the idea of platform module design. On the basis of not redeveloping the original functions, the existing problems of perception and decision-making are improved. Through the experimental demonstration in this paper, this method can indeed save the development cost and shorten the development cycle.

Wireless Movement-Tracking System Uses Low-Power Radio Frequency Signals

  • Magazine Article
  • TBMG-35987
Published 2020-02-01 by Tech Briefs Media Group in United States

A system called Marko uses signal reflections to provide scientists and caregivers with valuable insights into people's behavior and health. Marko transmits a low-power radio-frequency (RF) signal into an environment. The signal will return to the system with certain changes if it has bounced off a moving human. Novel algorithms then analyze those changed reflections and associate them with specific individuals. The system then traces each individual's movement around a digital floorplan. Matching these movement patterns with other data can provide insights about how people interact with each other and the environment.
