Autonomous driving to become more easy -written by Nitisha Gurjar (BA English Hons.)

Engineers are developing a low-powered sensor for making autonomous driving easier.

Today, the world has got so advanced and full of technology that we have self-driving cars. But these cars still face many issues to work properly. Together, scientists from Western Michigan University and the Department of Energy's Oak Ridge National Laboratory are advancing answers to this issue.

The reflective raised pavement signs that are already used to help drivers identify lanes are being fitted with low-powered sensors by ORNL engineers. Microchips inside the markers reportedly communicate information to passing cars regarding the shape of the road, according to a publication in IEEE Sensors by ORNL researcher Ali Ekti alongside main author Sachin Sharma of WMU. They are efficient even when glare, fog, snow, or other impediments render vehicle cameras or remote laser sensing, often known as LiDAR, problematic.

The technology not only offers more precise information about road conditions, but it also transfers some of the processing burden from the car's software to the infrastructure. This increases the driving range of electric vehicles, which encourages wider EV adoption.

According to Ekti they are aiming to make autonomous driving features reliable and secure in farther-flung locations. And also they are accomplishing that by transforming a useless piece of infrastructure into something that serves a lot more purposes.

The system has the ability to be used with both today's and tomorrow's standard autonomous driving capabilities, such as lane assist.

The initiative is part of a wider undertaking led by WMU, which is working along with research and business partners to create a relevant sensor and autonomous driving technologies such as radar retro-reflectors, high-definition mapping, computational offloading, and weather sensing. Zachary Asher, assistant professor of mechanical and aerospace engineering and director of the WMU Energy Efficient and Autonomous Vehicles Lab, said that WMU researchers are also using a vehicle traveling on a closed course to measure the decrease in vehicle energy use that is made possible by these technologies.

 

The sensors may also alert drivers to brief lane changes or closures in construction areas where high-definition maps may not be current. According to Ekti, marker sensors may potentially provide data on temperature, humidity, and traffic volume.  The project team intends to engage with students to create a more affordable alternative to more expensive off-the-shelf products by creating a smaller microprocessor for the markers.
