ZF introduces City Bus Assist, a sensor-based system for automated power steering and coordinated vehicle lowering at bus stops.
A city bus approaches its next stop. City Bus Assist guides the vehicle precisely along the curb. At the same time, the chassis automatically lowers to enable step-free boarding.
ZF supports public transport companies with integrated systems, new features, and software-based vehicle intelligence designed to improve safety, efficiency, total cost of ownership, and comfort.
In addition to City Bus Assist, ZF offers the following systems for city buses, among others:
– City Bus CMS: This emergency braking system, specifically designed for city buses, detects vehicles, cyclists, and pedestrians and can actively initiate braking maneuvers to limit or prevent collisions. As part of ZF’s ADAS portfolio, the system is based on the OnGuardMAX platform and features a specific braking profile to improve the safety of standing passengers. City Bus CMS is already used by various bus manufacturers and meets the increasingly stringent safety requirements for city buses.
– CDC Skyhook: A computer continuously adjusts the damper behavior to current driving conditions. This stabilizes vehicle movements, increases ride comfort, and improves overall driving dynamics.
e-comp Scroll: The oil-free and low-noise electric air compressor supplies compressed air to the brake and suspension systems. By reducing noise and vibration levels, it increases comfort, particularly in electric buses, while simultaneously lowering maintenance costs.
