Volvo Trucks North America at the ATA's Technology & Maintenance Council (TMC) Annual Meeting Monday in Nashville announced two initiatives to modernize heavy-duty vehicle connectivity: an expansion of automatic over-the-air software updates and the development of a high-speed wireless truck-trailer connector.

Maddie Sullivan, product marketing manager for Volvo Trucks North America.Volvo's automatic software update program has moved more than 80% of its connected fleet onto the latest software versions in the last six months, up from 25% prior. This has resulted in a 24% reduction in unplanned stops for repairs or maintenance, the company said. Successful updates have increased from approximately 1,000 per month to 1,000 per day, with the system capable of dispatching up to 10,000 daily.

"Our trucks today are basically smartphones on wheels," said Maddie Sullivan, product marketing manager for Volvo Trucks North America, adding technology moves and updates so fast, a truck bought just six months ago isn't necessarily the same as the same truck purchased today.

Previously, fleet managers were required to contact customer service or visit a dealership to perform software updates. Under the expanded system, updates are delivered in the background, allowing drivers to initiate installations while parked or during scheduled breaks.

New smart tractor-trailer connector

In collaboration with TECTRAN Manufacturing, Volvo is working to develop an enhanced tractor-trailer connector it intends to become a new industry standard in the U.S. and Canada.

The new design, developed by Volvo engineers in Sweden, updates the current J560 seven-pin connector. While the traditional connector was built primarily for lighting and basic braking signals, the new solution adds high-speed wireless data transfer capabilities within the existing housing.

Sullivan noted that a modern truck is a sophisticated, connected machine, adding that the trailer has to evolve at the same pace.

The wireless interface is designed to support real-time data exchange for advanced safety systems and cameras; powertrain optimization, including improved braking and propulsion; and direct trailer status alerts for drivers and fleet managers.

The technology is based on U.S. patents issued to Volvo in 2024 and is compatible with existing infrastructure. Volvo plans to work with industry stakeholders to promote the connector as the successor to the current 12-volt round-pin system, Sullivan added.
