Meritor WABCO Unveils RSS 1M Trailer Safety System

Meritor WABCO introduced the Roll Stability Support (RSS) 1M, a two-sensor, one-modulator system that completes a diverse offering of trailer safety systems to provide the benefits of both ABS and trailer stability control integrated into a single compact unit.

The risk of rollover from driving actions, including collision avoidance maneuvers; sudden lane changes and acceleration in a curve, can be mitigated or prevented as a result of the RSS 1M, thereby assisting the driver in maintaining control of the vehicle.

The system automatically accounts for the load status and calculates lateral acceleration while driving. If the lateral acceleration exceeds a specific value, low pressure check brake applications are applied. If the system detects a potential rollover during the brake check process, a full brake application is put into effect. The Meritor WABCO RSS 1M is derived from the proven RSS 2 M system that has been available to fleets for 9 years.

“As a leader in trailer safety systems, with more than 3 million ABS systems in the field, we listened to our customers and developed an effective solution for customers that have been requesting a one modulator variant of our proven RSS 2M,” said Mark Melletat, director of trailer systems. “There are nearly 20,000 RSS 2M systems in the field, and now the RSS 1M broadens our portfolio to support those fleet applications that desire to upgrade from their current 1M ABS to include the advanced features and technology of stability control.”

This RSS 1M safety system is targeted for vans, reefer units, flatbeds and is easily retrofitable to upgrade existing equipment. Features and benefits includes proven anti-lock brake performance, stability control, integrated control and supply port screens, a tank mountable ECU/valve assembly, optional lift axle control, and Meritor Tire Inflation System (MTIS) by PSI monitoring. Additional capabilities include air and spring suspension applications, generic input and output, onboard data recorder and telematic broadcasting capabilities.

Meritor WABCO also announced that its Vehicle Control Systems will market and distribute SafeTraK, Takata’s vehicle sensor system which offers Lane Departure Warning (LDW), Forward Collision Warning (FCW) and Driver Alertness Warning features to the North American commercial vehicle industry. The agreement is a result of a newly forged alliance between Meritor WABCO and Takata Corporation’s U.S. subsidiary, TK Holdings Inc.

This vision-based system monitors the road ahead and audibly warns drivers if they unintentionally depart from a lane or the road. The SafeTraK LDW system alerts drivers of weaving, lane drifts or lane changes that occur without a turn-signal application by detecting and classifying lane markers on the road through a fully integrated, compact unit.

The unit is composed of a camera, optics, processor and a power supply that assist in tracking and projecting the lane ahead. Installation and setup is simple. The system automatically calibrates itself using the unit’s integrated diagnostics and can be installed directly on the vehicle’s windshield in less than an hour.
