HARMAN OTA is the industry-leading solution for managing full-vehicle software and keeping it up-to-date
HARMAN Over-the-Air (OTA) Software Updates for Truck and Bus Vehicle Manufacturers
An Era of Software Defined Vehicles
The transportation industry is undergoing a major transformation driven by new technologies that enable companies to increase both productivity and profitability. GM Insights predict the U.S. heavy-duty trucks market will exceed $430 billion by 2026 to support the increased demand to carry materials, goods, tools and equipment.

​The performance of companies in the transportation industry is highly impacted by their operational efficiency. Today, software updates for the various ECUs present on a typical truck/bus are mostly carried out manually and require an industry average of 2.3 days of downtime. Even when performed automatically, OTA software updates can take several hours, including immobilization of the truck for a full workday or longer in specialized locations. Therefore, poorly managing or not executing software updates​ can take a serious toll on business productivity. Introducing a proven OTA software update mechanism and a supporting in-vehicle architecture enables innovative truck and bus manufacturers to better serve their customers by remotely updating their fleets on the road with virtually zero downtime, improving productivity and minimizing maintenance-related costs.

Based on its current advanced OTA technology and industry expertise, HARMAN OTA can be integrated to any E/E architecture selected by the truck manufacturers and is optimized for an OTA configuration and to update/validate ECUs on the road with near-zero interruptions. These activities are all streamlined by a central back-end system that manages the entire truck group fleet (all brands within the truck group, all models/sub-models, all countries, etc.).​
