Did You Know?

WABCO is the first to the NA market with OnGuard. 90,000+ systems in the field and 32 billion highway miles.

WABCO is focused on continuously developing integrated safety technology and efficient system solutions, delivered by the broadest and most experienced support network


In 1990 WABCO pioneered the introduction of anti-lock braking (ABS) for commercial vehicles in North America. In 2002 we were the first to launch Roll Stability Control for pneumatically braked trucks, tractors and buses. Since that time we have continued to develop a broad portfolio of stability control systems with advanced features and flexibility to meet your individual needs. Today the SmartTrac family represents ABS, automatic traction control (ATC), Electronic Stability Control (ESC) and Roll Stability Control (RSC). SmartTrac systems are currently used in commercial vehicles, construction vehicles, fire and emergency, bus, coach and military applications. These systems have demonstrated proven performance in assisting the driver in reducing vehicle accidents and reducing overall vehicle operating costs.
