Questar’s AI-powered vehicle health management platform reveals bus fleet malfunctions, reduces safety risks, lowers repair costs and improves uptime


Questar identified 10% of tested buses in Kavim Public Transportation’s fleet with two malfunctions requiring repair; Repair before scheduled maintenance saves money and keeps passengers safe

TEL AVIV, Israel, June 7, 2022 /PRNewswire/ — Questar Auto Technologiesthe leader in predictive vehicle health, today announced that its Vehicle Health Management (VHM) platform, which combines artificial intelligence with automotive expertise, has successfully provided early warning of major malfunctions in 10% of a bus fleet that was tested in the pilot operated by Israel-based Kavim Public Transport company.

Today’s vehicles undergo expensive maintenance at fixed times as a preventive measure, even if they are in good condition. Yet fleet owners around the world still spend hundreds of billions of dollars a year fixing vehicle malfunctions that weren’t detected in time, leading to excessive repair costs and unnecessary downtime. .

Questar recently ran its AI-based analysis software on a heterogeneous fleet of Kavim – to monitor the health of its city and intercity buses – and determined that 90% of the buses tested were functioning properly while 10% of the buses tested had two primary malfunctions that were not observable through vehicle fault codes. The first malfunction was a problem with the vehicles exhaust systems due to leaking engine oil – a serious problem that was not flagged by engine controllers. The second malfunction was a problem with the particulate filters in the exhaust systems, which disrupted the pollutant combustion cycle process that ensures proper filtration of emissions.

By identifying vehicle malfunctions before they turn into costly or dangerous problems, Questar minimizes vehicle downtime due to malfunctions and repair times and helps fleet owners save thousands of dollars per vehicle. . Field data shows that by using Questar’s vehicle health management solution to detect vehicle malfunctions before they occur, fleet operators can benefit from a 30% reduction in costs on spare parts, a 10% reduction in fuel consumption, a 20% reduction in accidents and up to 75% reduction in unnecessary downtime. The payoff goes beyond dollars and cents: real-time health monitoring optimizes emissions filtration and saves fuel, making fleets more environmentally sustainable.

“Questar was born following the acquisition of SafeRide by Traffilog, with the vision to take the AI ​​and deep learning capabilities of SafeRide and combine them with the data collection capabilities and deep knowledge of the Traffilog Automotive, as well as its strong customer base, to create a first-of-its-kind predictive health platform,” said Erez Lorber, CEO of Questar. “Today, that vision has turned into reality: Questar is a one-stop-shop offering everything the automotive ecosystem needs to convert vehicle data into actionable insights in real time. Technology enables us to help fleet owners like Kavim to reinvent traditional vehicle maintenance and repair practices – avoiding unnecessary expense and keeping bus drivers and passengers safe.”

By combining AI-based analytics software, advanced telematics, years of accumulated data insights, and automotive know-how, Questar is redefining traditional vehicle maintenance practices to better manage the condition of vehicles and identify vehicle malfunctions before they become unnecessarily expensive or turn into safety risks. Questar’s technology is deployed in more than 350K vehicles in more than 20 countries, providing constant, meaningful and cost-effective information to automakers, suppliers and fleets.
