Bitsensing unveils retrofit ADAS kit for bus & truck fleets

Bitsensing has launched an aftermarket Advanced Driver Assistance Systems (ADAS) product for buses, trucks and other commercial vehicles, as fleets face pressure to reduce collisions and improve driver awareness.

The product, called ADAS Kit, retrofits safety warning functions into existing vehicles. It combines radar and camera sensors with a controller and an in-cab display that issues alerts while a vehicle is driving, manoeuvring or stationary.

Commercial vehicles account for a significant share of severe road incidents in major markets. Heavy goods vehicles are involved in 14% of all fatal road crashes in the EU and 9% in the US, according to figures the company cited from ERSO and NHTSA.

Warning features

ADAS Kit includes a Blind Spot Information System and a Moving Off Information System. It also offers Forward Collision Warning, Rear Collision Warning, Front Vehicle Start Alert and Surround View Monitoring.

Alerts appear through a driver interface inside the vehicle. The system is aimed at urban driving, where large vehicles encounter pedestrians, cyclists and motorcycles, along with frequent stop-start traffic.

Bitsensing describes the product as a complete package for fleet deployment rather than a set of separate components. The system uses sensor fusion between radar and cameras to improve detection of road users and speed up hazard warnings in commercial-vehicle conditions.

Regulatory context

The launch comes as Europe tightens safety requirements for large vehicles. Bitsensing says the product supports key UNECE regulations, including R151 for Blind Spot Information System and R159 for Moving Off Information System, which form part of Europe's safety standards for large vehicles.

Aftermarket driver-warning systems have become a focus for fleet operators that keep vehicles in service for long periods. While new vehicles may include more safety functions as standard, a large installed base of trucks and buses remains on the road without modern alerts. Retrofit systems offer an alternative for operators that want to update safety functions without replacing vehicles.

Retrofit installation

Bitsensing says ADAS Kit has a retrofit-ready architecture and requires minimal maintenance after installation. It is designed for quick installation with limited disruption to fleet operations.

The standard configuration includes radar sensors mounted at the front and corners of the vehicle for continuous object detection, plus camera systems for visual context. An integrated controller runs ADAS functions, and a driver display provides real-time warnings and alerts.

The radar sensors use NXP's STRX chipset, according to the product description. Bitsensing works with NXP Semiconductors on radar development and commercial partnerships.

Early deployment

The product has been trialled in South Korea. Bitsensing recently installed ADAS Kit on buses operated by Koreawide Express Group on routes in downtown Daegu, a city with a population of 2.3 million.

The collaboration began with intercity and city buses operating in real road environments, with plans to expand to more than 500 buses. The pilot continues on those Daegu routes.

Bitsensing, founded in 2018, develops radar products for automotive and other applications. It has raised USD $52 million in funding from investors including AF WPartners, Korea Development Bank and Mando Corporation.

The commercial vehicle safety market has drawn increased attention from technology suppliers as regulators and cities demand better protection for vulnerable road users. Fleets also face rising insurance costs and operational pressure tied to incidents, downtime and driver retention. Retrofit packages that combine cameras, radar and in-cab alerts are emerging as a growing category alongside factory-fit options.

Dr. Jae-Eun Lee, Chief Executive Officer of Bitsensing, said the product targets gaps in the installed base of vehicles:

"Commercial vehicles operate in some of the most demanding road environments, yet many fleets still lack access to modern driver warning systems. ADAS Kit was developed to close that gap, delivering a complete, system-level ADAS solution that can be deployed on existing vehicles without redesigning the vehicle platform. By integrating radar, camera, and proven ADAS software, we are making advanced safety warnings more accessible, practical, and scalable for real-world fleet management operations."
