Building on the success of Goodyear’s and TNO’s integration of tire intelligence into antilock braking systems (ABS) showcased at CES 2024(opens in a new window or tab) (refers to a different website), this project further underscores the role of tire data in advancing automotive safety systems.
The AEB system, designed to help prevent or reduce the severity of collisions by automatically applying the brakes when a crash is imminent, has become a key focus in the automotive industry. While existing systems are typically tuned for high-friction surfaces like dry asphalt, integrating Goodyear SightLine(opens in a new window or tab) (refers to a different website), the company’s suite of tire intelligence solutions, can help the AEB system to function effectively across a wider range of driving environments, including low-friction surfaces. Through the contact patch with the road, tire intelligence can provide the AEB with deeper insights into actual tire and road conditions to enable smarter, more precise decision-making.
‘Safety is a cornerstone of Goodyear’s commitment to innovation,’ said Chris Helsel, senior vice president and Chief Technology Officer at Goodyear. ‘By providing critical inputs about tire and road conditions into AEB systems, we are helping OEMs and their customers take a leap forward in safety, well ahead of the National Highway Traffic Safety Administration’s (NHTSA) 2029 mandate(opens in a new window or tab) (refers to a different website) for AEB systems in passenger vehicles. Beyond this mandate, AEB systems will play a critical role in automated driving, helping to provide a comprehensive safety envelope at all times.’
Recent testing indicates that an enhanced AEB system incorporating Goodyear SightLine technology has the potential to assist in mitigating impacts at speeds of up to 50 mph on low-friction surfaces. Additionally, this integration can improve precise braking, allowing the system to engage at the right moment to protect passengers and other road users alike. Overall, integration of AEB with SightLine insights on tire and road condition data helps ensure robust performance across diverse scenarios.
‘TNO is dedicated to enhancing the safety, efficiency and sustainability of vehicles.’ said Martijn Stamm, marketing director, Unit Mobility & Built Environment, TNO. ‘Our collaboration with Goodyear aims to predict the braking distance of a vehicle in more conditions, like dry and wet asphalt, to trigger the AEB timely to reduce accidents and to ultimately safe lives. This knowledge is a key enabler for a safe introduction of higher levels of automation.’
