ZF Introduces City Bus Assist: A Smarter and Safer Way to Approach Bus Stops

• New City Bus Assist system enhances accessibility and passenger comfort at every bus stop.

• Intelligent integration of ADAS, braking, steering and suspension systems further improves safety in complex urban traffic.

• ZF will showcase its latest commercial vehicle technologies at Hall 21, Stand B42 during IAA Transportation 2026.

By intelligently integrating advanced driver assistance systems (ADAS), chassis technologies and software, ZF enables bus manufacturers and public transport operators to improve safety, operational efficiency, total cost of ownership and passenger comfort.

A Smarter Bus Stop Approach

Imagine a city bus approaching its next stop in heavy urban traffic. Thanks to City Bus Assist, the driver receives automated steering support that guides the vehicle precisely alongside the curb. At the same time, the suspension system automatically lowers the bus to reduce the step height, making boarding and alighting easier for passengers with reduced mobility.

Meanwhile, the braking system delivers smooth and predictable deceleration, creating a safer and more comfortable experience for both seated and standing passengers.

The result is a bus stop maneuver that is safer, smoother and significantly more accessible.

This integrated scenario was demonstrated during ZF's Commercial Vehicle Tech Day (CV Tech Day) ahead of IAA Transportation 2026, showcasing technologies that could soon become part of everyday urban public transport operations.

Integrated Intelligence for Urban Mobility

Commenting on the company's latest developments, Ivan Brajdic, Head of R&D for ZF Commercial Vehicle Solutions, said:

"Urban buses operate in highly complex traffic environments where they must simultaneously protect passengers and other road users, deliver a comfortable ride in stop-and-go traffic, and maintain reliable operation. By connecting advanced driver assistance systems, chassis control technologies and intelligent software functions, we support drivers in critical situations while improving passenger comfort, accessibility and fleet efficiency."

Technologies Demonstrated by ZF

City Bus Assist

Making its public debut at CV Tech Day, City Bus Assist provides automated steering assistance during bus stop approaches. The system accurately guides the vehicle alongside the curb while reducing lateral tyre wear. Integrated suspension control optimizes the kneeling function, minimizing the height difference between the curb and the bus floor to improve accessibility.

City Bus CMS (Collision Mitigation System)

Developed specifically for urban buses, City Bus CMS actively detects vehicles, cyclists and pedestrians. If necessary, it automatically applies the brakes to help prevent collisions, improving safety for both passengers and vulnerable road users.

The system is based on ZF's OnGuardMAX ADAS platform and has already been adopted by several leading bus manufacturers.

CDC Skyhook

This real-time software-controlled damping technology continuously adjusts shock absorber performance according to road conditions, significantly improving ride comfort and vehicle stability.

e-comp Scroll

ZF's oil-free, low-noise electric air compressor supports braking and suspension systems while reducing noise, vibration and maintenance requirements—particularly valuable for electric buses.

A Comprehensive Portfolio for Bus Manufacturers and Operators

Alongside its latest innovations, ZF continues expanding its portfolio for bus manufacturers and public transport operators.

At Busworld Türkiye, the company recently presented its AxTrax 2 LF electric portal axle with optional digital condition monitoring as well as new digital fleet management capabilities through ZF Bus Connect.

Together with ADAS, braking, steering, chassis, driveline, electrification and digital fleet management technologies, these solutions underline ZF's long-term commitment to the global bus industry.

ZF at IAA Transportation 2026

ZF will present its latest commercial vehicle technologies at IAA Transportation 2026, taking place in Hanover, Germany, where visitors can find the company at Hall 21, Stand B42.

The new City Bus Assist concept demonstrates how intelligent system integration can make urban bus operations safer, more accessible, more efficient and more comfortable—helping shape the future of public transportation.
