A multi-functional altitude simulation system called MEDAS helps vehicle and engine manufacturers decrease development and testing timeframes. The MEDAS system is a compact altitude simulator that supplies the correct atmospheric conditions to reproduce a wide range of environmental scenarios. It is suited for a variety of testing applications, including calibration, durability, and road to rig […]
Test and alignment software/hardware setup handles public-safety radios
An Auto-Test setup works with the L3Harris Technologies XG-25M, XG-25P, and XG-15P radios on the VIAVI 3920B Radio Test Platform and 8800SX Digital Radio Test Set. The development enables automated test and alignment of the best-in-class L3Harris XG-25M, XG-25P, and XG-15P two-way radios. These Auto-Test applications perform fast, repeatable, and accurate alignment and test matching […]
Protecting autonomous vehicle control circuits
The subsystems that make up an autonomous vehicle should be bullet-proof when it comes to electrical interference and transients. James Colby, Prasad Tawade Littelfuse, Inc. Those who follow autonomous vehicle technology are usually well aware of its benefits. But the safety and convenience autonomous vehicles offer can only come if the vehicle electronics is reliable […]
Optimizing in-vehicle data networks
Physical channels have limits that affect the practicalities of automotive network architecture and communication protocols. Here’s the lowdown on current work aimed at breaking bandwidth bottlenecks. CHRIS RUSCH, BERT BERGNER | TE Connectivity It has become a truism that we have an insatiable appetite for data. Not so obvious is the effect our need for […]
Low-resistance ohm meter excels at tests with long leads
A digital low-resistance ohmmeter can deliver reliable results when using long test leads. The DLRO2, a 2-A handheld tester, is a candidate for use in production line testing and industrial applications. This robust and intuitive handheld instrument offers a ‘difference meter’ that allows for quick data comparisons. Applications that require long test leads are not […]
The sense-think-act model of autonomous vehicles
Electronics and software tend to be more important than the mechanics of autonomous vehicles. This shift has serious implications for how vehicles are designed. Puneet Sinha | Mechanical Analysis Div., Mentor, a Siemens business Though certain autonomous functions, especially driver-assist and active-safety features, have started to show up in some recent-model vehicles, the goal of […]
CAN for better autonomous vehicles
Handing data-intensive lidar and radar processing at the sensor itself can let CAN connections make autonomous vehicle networking more economical. KENT LENNARTSSON | Kvaser AB There’s no question that as the autonomous driving capabilities advance, so do the requirements for transmitting large amounts of data. A 2017 paper by Stephan Heinrich, currently a systems architect […]
Open standards for driverless cars
Why unsafe autonomous vehicle systems are passing undetected during development. Dr. Luca Castignani, MSC Software In February, McAfee exposed the alarming gap between the road test and real-world performance of autonomous vehicle sensors. In a demonstration, McAfee was able to fool a Tesla car into accelerating to 85 mph in a 35 mph zone using […]
OEM guide to ADAS development
As automotive electronics becomes more complex, the quest is on for economical ways to cover the widest possible range of requirements. Eric Pinton | Renesas Electronics In recent years, few topics have stoked the automotive industry’s collective enthusiasm like autonomous vehicles. Pushed by widely publicized breakthroughs in connected vehicle development, deep learning software, and data-driven […]
Safety and cyber security for the connected car
Even the best coding practices are likely to result in vehicles infected with 10,000 software bugs. Simulated attacks can sniff out vulnerabilities before the car hits the road. Hwee Yng Yeo, Rick Kundi | Keysight Technologies The era of the connected car, and a growing concern over cybersecurity threats, is here. Safeguarding the connected car […]
