How Bitsensing Fills the Safety Gap in Commercial Vehicles

Commercial vehicle safety is less about “future technology” than it is about what happens on the road today. Instead of promising autonomous driving, Bitsensing’s ADAS Kit focuses on filling the “radar gap” that still exists in many commercial vehicles with a practical, warning-centered system. Its execution model is built around a closed validation loop - installation, calibration, updates, and data - while aggregating volume to fundamentally change the cost structure. In the end, the logic is simple: reduce just one accident, and the commercial vehicle market responds.

Accidents That Don’t Stay in the Statistics
Commercial vehicle accidents rarely remain abstract statistics. Large vehicle bodies, long braking distances, and structurally wide blind spots mean that even a minor collision can result in damages worth tens of millions of won. In many cases, operators calculate their next contract and insurance premium before even considering an insurance claim. As a result, accidents are often handled as costs rather than officially recorded incidents. A single mistake on the road is translated directly into a line item on the profit-and-loss statement.
Yet many of these heavy industrial vehicles still operate without radar. While safety regulations such as AEBS for new vehicles - especially medium and heavy commercial trucks - are becoming stricter, the majority of existing commercial vehicles on the road remain limited to camera-based monitoring systems. Blind spots, low-speed congestion, and pedestrian proximity risks are still largely dependent on driver experience and intuition. This is not a technology problem; it is a gap left in the market.
That gap is precisely where Bitsensing’s aftermarket integrated ADAS solution, the ADAS Kit, enters - designed to address today’s realities, not tomorrow’s promises.



“Reducing Just One Accident Is Enough”

“Commercial vehicles are huge and expensive. Even a small contact accident can cost tens of millions of won,” says Jae-Eun Lee, CEO of Bitsensing. “But operators often avoid insurance claims because higher premiums can hurt the business.”
When explaining the product, Lee speaks first about the field - not the technology. He understands that commercial vehicle accidents are not merely safety issues, but business risks tied directly to operations, contracts, and insurance rates.
“That’s why we believed that if this kit could prevent even a single accident, it would more than pay for itself.”
ADAS Kit is an aftermarket integrated ADAS solution designed for existing commercial vehicles. It can be installed without changing the vehicle platform and combines radar and camera sensors to provide real-time warnings such as Forward Collision Warning (FCW), Rear Collision Warning (RCW), and Blind Spot Information System (BSIS). Additional functions - including Surround View Monitoring (SVM), Front Vehicle Start Alert (FVSA), and Moving-Off Information System (MOIS) - are integrated into a single system.
The goal is not autonomous driving, but driver awareness. That distinction matters even more in commercial vehicles. While passenger-car ADAS can sometimes create the expectation that “the car will handle it,” commercial vehicle drivers must ultimately make the final judgment themselves when controlling large, heavy vehicles. For them, the most critical need is not automated control, but timely warning.
Bitsensing designed ADAS Kit with a warning-centric philosophy for exactly this reason. It is not a technology that “prevents accidents” by taking over, but one that enables drivers to recognize dangerous situations before they escalate. It is, in effect, a redesign of time on the road.

Why Commercial Vehicles Still Lack Radar

The commercial vehicle market has long occupied an ambiguous position. Vehicles are expensive, but volumes are far lower than passenger cars. Vehicle types are diverse, operating environments harsher, and customization unavoidable. As a result, it has rarely appeared attractive at scale to large Tier-1 suppliers.
The reality is that while many commercial vehicles have camera-based monitoring, radar-based driver warning systems remain rare - both domestically and overseas, including in the United States.
“It’s the same in the U.S.,” Lee notes. “Most existing vehicles just have camera monitors. There are very few companies offering proper radar-based aftermarket solutions.”
The key point is not that the technology does not exist, but that complete products do not. Commercial vehicle environments demand more than sensors alone - they require seamless integration of installation, calibration, maintenance, driver interfaces, field feedback, and updates. Very few companies manage this entire chain without interruption. ADAS Kit is an attempt to step directly into that gap.



Why Imaging Radar Was Not Used

Given Bitsensing’s reputation as a leading 4D imaging radar startup, some may find it surprising that ADAS Kit does not use imaging radar.
“For this application, imaging radar is simply too high-end,” Lee explains. “Many existing commercial vehicles don’t have radar at all. Even a compact radar providing reliable warnings can statistically reduce accidents by more than 30%.”
This does not mean lowering performance - it means redefining the problem. For Bitsensing, the issue is not how dense a point cloud can be generated, but how quickly the safety gap on today’s roads can be closed. Warning comes first, perception next, and autonomy later. ADAS Kit does not lower the technological ceiling; it adds a practical on-ramp.



Not Legacy Chips, but the Latest Radar Technology

Another long-standing convention in the commercial vehicle market is the trickle-down of technology: semiconductors and sensors that have completed their lifecycle in passenger cars are often reused in commercial vehicles.
Bitsensing rejected that approach. The radar used in ADAS Kit is based on the latest passenger-vehicle chipsets. While conventional corner radars typically offer detection ranges of around 160 meters, this radar reaches approximately 240 meters in the same form factor - approaching long-range radar performance.
“There’s no reason commercial vehicles should rely on outdated technology,” Lee says. “Our goal was to offer passenger-car-level capability at an affordable price.”
The system consists of front and corner radars based on NXP STRX chipsets, cameras, an integrated controller, and a driver display. A typical configuration includes three radars (one front, two side, with an optional rear radar), four cameras for buses, and SVM. Camera partners have not been disclosed.

Validation on Real Roads and a Volume-Driven Strategy

ADAS Kit is already in operation. In November 2025, Bitsensing began a pilot deployment with Korea-based transportation operator Korea Wide Group. After real-world validation, the company secured supply contracts for more than 500 vehicles. Installations are currently underway on express buses operating routes such as Dongdaegu - Incheon Airport, with plans to expand across the group’s network.
Pricing ranges from approximately KRW 3 - 5 million for a configuration with three radars and four cameras, excluding installation costs. In the aftermarket, installation quality and maintenance networks often become the real bottlenecks to scaling. Bitsensing therefore begins with large fleet operators, where standardized installation reduces labor costs.
This is not merely a reference project. It represents the first real execution of Bitsensing’s broader strategy: targeting markets that Tier-1 suppliers overlook, aggregating volume directly, and using that volume to reshape pricing structures.
“Even if individual operators only have 5,000 or 10,000 vehicles, by aggregating them we can offer pricing equivalent to 100,000 units,” Lee explains. “Bitsensing is light and fast - we can move that way.”



What Startups Do That Tier-1s Don’t

Another reason ADAS Kit works lies in how it is supported. Commercial vehicles differ by model, country, route, installation position, and driver habits. Customization is unavoidable. Large Tier-1 suppliers, however, rarely adapt their specifications for small-volume markets.
“Big companies deliver to spec and stop there,” Lee says. “They don’t change anything. As a startup, we can review and implement changes quickly.”
Here, competitiveness is defined not by sensor performance alone, but by response speed in the field. If warnings are too frequent, drivers disable the system; if they come too late, accidents are not prevented. Striking that balance requires continuous feedback and updates.
“There are cases where mandatory AEB systems are turned off by drivers due to ghost braking or quality issues,” Lee notes. “That’s how a safety feature becomes unusable.”
Commercial vehicle customers want fewer features - but ones they don’t have to turn off. ADAS Kit is designed around that principle.



Regulations as Market Entry Points

Bitsensing states that ADAS Kit meets UNECE R151 (Blind Spot Information System) and R159 (Moving-Off Information System) requirements. But this is more than a regulatory checklist. Commercial vehicle safety regulations are expanding beyond new vehicles toward operations and data. Fleet operators need lower risk; insurers want evidence. Compliance becomes the language of market entry.
This is why Bitsensing also discusses insurance integration. While Korea offers premium discounts for certain ADAS installations, many overseas markets do not. Technology alone does not scale commercial vehicle ADAS - regulations, insurance, and operational data must move together.
“As we roll this out in earnest this year, data will accumulate,” Lee says. “By comparing it against historical accident statistics, we can persuade customers with numbers.”
Warnings change driver behavior, behavior becomes data, and data becomes persuasion. In the commercial vehicle market, numbers speak.



From the Past to the Present: A Radar Systems Company’s Choice

In a 2023 interview with AEM, Lee described Bitsensing not as a company competing on imaging radar chips, but as one that designs complete radar systems. At the time, he explained that many radar technologies fail to reach mass production because they cannot overcome real-world field issues - branches, tunnels, deserts, interference, EOL yield, calibration.
ADAS Kit is the most practical expression of that philosophy. Commercial roads are not laboratories, and the aftermarket is even harsher. Companies that have connected the entire chain - from design to deployment - hold the advantage. ADAS Kit is less a collection of cutting-edge technologies than the result of knowing where not to apply them.
Returning to the idea of “one accident,” the logic becomes clear. Many commercial vehicles still operate without radar. Bitsensing chose to fill that gap first. And the justification does not require a grand future vision - only today’s data showing that one accident was avoided. That is enough to move the commercial vehicle market.
