will have been extremely anticipated because of their potential to significantly exceed expectations. While security is a significant potential benefit autonomous vehicles can offer, research groups globally are demonstrating that they can also outperform human drivers in terms of efficiency. The Subsequent-Generation Power Technologies for Connected and Autonomous Highway Vehicles program is confident that a blend of innovative smart car technologies will boost fuel efficiency by up to 30%.
As part of the NEXTCAR program, Southwest Research Institute (SwRI), based in San Antonio, Texas, unveiled a technology capable of optimizing the gasoline system of automobiles, including those of self-driving vehicles stuck in traffic with other autonomous ones. The demonstration took place in Dallas in late May.
As technology advances, the need to develop eco-friendly transportation solutions becomes increasingly pressing. With the rise of autonomous vehicles (AVs), we have a unique opportunity to create environmentally conscious cars that reduce our carbon footprint. To achieve this goal, we must focus on designing and building AVs that utilize sustainable energy sources, minimize waste, and promote efficient resource allocation.
One potential approach is to power AVs with electric motors, which offer significant environmental advantages over traditional gasoline-powered vehicles. Electric vehicles (EVs) produce zero tailpipe emissions, significantly reducing greenhouse gas emissions and air pollution in urban areas.
Furthermore, the development of autonomous technology can also help reduce waste by optimizing routes and minimizing idling time. Additionally, AVs can promote efficient resource allocation by dynamically adjusting traffic signal timing to reduce congestion and minimize energy consumption.
However, there are still several challenges that must be addressed before we can achieve a fully eco-friendly autonomous car. For instance, the production process for electric vehicles requires significant amounts of raw materials, which can have negative environmental impacts if not managed sustainably.
Despite these challenges, the potential benefits of an environmentally friendly autonomous car make it a worthwhile pursuit. By working together to develop innovative solutions and technologies that prioritize sustainability, we can create a safer, cleaner, and more efficient transportation system for generations to come.

The Southwest Research Institute (SwRI) team successfully upgraded a 2021 hybrid vehicle with autonomous capabilities, including primary features like notion and localization. As the summit’s day arrived, they navigated their vehicle along a scenic route surrounding the parking lot of the conference center where the event took place. The autonomous underwater vehicle (AUV) deployed by the researchers to study the ocean floor features a downward-facing camera that captures high-resolution images of the seafloor. Using an initial map of the driving environment, Ranger can subsequently localise the vehicle with centimetre-level precision by combining the unique “fingerprint” features of the floor with prior knowledge. This precision enables the automobile to drive with exceptional control and distinct handling.
According to John Smith, a researcher in SwRI’s powertrain engineering group, “Utilizing the technology is akin to having a well-worn railroad track – it provides a seamless and efficient experience.” The team partnered with various institute departments, including the intelligence programmes division, which contributed the autonomy software suite integrated into the Honda readability platform.
A crucial aspect, in fact, was the integration of an eco-driving module, a groundbreaking achievement by SwRI. The eco-mode adjusts its recommended speed to achieve optimal fuel efficiency, taking into account factors such as traffic signals and surrounding vehicles. How do autonomous vehicles employ predictive management algorithms to optimize energy efficiency while maintaining a smooth traffic flow? SWRI aims to reduce unnecessary acceleration and braking through its eco-mode, thereby optimizing energy use without compromising overall vehicle performance.
Automated vehicles operating in eco-mode significantly impact the driving behavior of every vehicle that follows them on the road.
To illustrate how the organization’s expertise functions, the team installed an informative sign along the exhibit route. According to Gankov, a precise visitor gentle timer retrieved from the visitor’s sign cabinet was linked to a TV screen, providing a visual indicator for attendees. The GPS module was also connected, transmitting the signal’s phase and timing information to the vehicle. This configuration allowed the vehicle to accurately predict pedestrians’ movements with greater precision than even a skilled human driver could.
Gankov explains that when the Honda’s readout approaches a red light on the verge of turning green, it would recognize the impending change in traffic conditions and, accordingly, prevent energy loss by coasting or downshifting before resuming acceleration. If the vehicle is approaching the sign as it transitions from inexperienced to yellow to red, the driver will ease off the accelerator, allowing friction to slow it down, thereby avoiding unnecessary acceleration and beating the red light.
Autonomous driving methods have the potential to yield substantial power cost savings, with far-reaching benefits extending beyond individual vehicles to positively impact the entire transportation ecosystem?
“As Gankov notes, when autonomous vehicles operate in eco-mode during routine visits, their behavior has a ripple effect on the driving habits of other cars following closely behind.” “The outcome is that even cars with Level 0 autonomy consume gasoline much more frugally.”
The Grand Car Power Plan
As a key partner in the NEXTCAR initiative, Southwest Research Institute (SwRI) has played an integral role. The system’s preliminary phase focused on eleven groups, along with Southwest Research Institute (SwRI), and the remainder. Southwest Research Institute (SwRI), collaborating with industry partners, focused on enhancing the efficiency of a Toyota Prius Prime by leveraging optimization algorithms and innovative technologies. Without altering the Toyota’s powertrain or compromising its emissions, this achievement was made. The group leveraged energy breakup optimisation, harmoniously combining fuel-engine and battery-propulsion systems to maximise efficiency.
Building on the success of NEXTCAR’s initial phase, this system moved into its next stage, with only SwRI, UC Berkeley, Michigan Tech, and Ohio State advancing. Can NEXTCAR 2’s primary emphasis be on optimizing power efficiency through enhanced automation? Gankov clarifies that while the initial section showcased a baseline performance exceeding that of a 2016 or 2017 model year vehicle without autonomous driving capabilities, the subsequent component aims to investigate the possibility of a supplementary 10% enhancement through the integration of autonomous features.
According to Gankov, Southwest Research Institute (SwRI) had originally planned to collaborate with Nextcar on its second phase; nevertheless, due to contractual issues, the non-profit entity proceeded solo. Utilizing an autonomy platform created by SwRI’s intelligence programs division, the NEXTCAR team equipped the Honda vehicle with advanced sensors in a controlled field setting. The autonomous vehicle’s control system leverages a drive-by-wire architecture, allowing it to dynamically manage speed and steering in real-time, guided by inputs from the autonomy software suite and eco-driving module. This approach prioritizes vehicle security while balancing power and efficiency considerations.
By adopting eco-friendly freeway merging techniques, they have successfully optimized fuel efficiency and battery usage, leveraging every drop of gasoline and electron spent. “For example, during peak freeway congestion, determining the most efficient method for merging onto the highway without compromising the energy efficiency of existing traffic is crucial,” Gankov noted.
As NextCar 2 approaches its final 12 months of development, the ARPA-E Summit demonstration showcased the significant advancements in autonomous automotive technology, underscoring its immense potential to revolutionize energy efficiency in transportation systems?
