Meritor WABCO announced the Roll Stability Support (RSS) 1M, a two-sensor, one-modulator trailer safety system that provides 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, the company says, 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 its 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 trailer systems, Meritor WABCO. “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.”
The RSS 1M safety system is targeted for vans, reefer units, flatbeds and is easily retrofitable to upgrade existing equipment. Features and benefits include 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.
