SmarTrac ESC helps meet proposed rule

Meritor WABCO Vehicle Control Systems has confirmed that its SmarTrac Electronic Stability Control (ESC) product has the technology to help ensure that truck tractors and motorcoaches are able to meet the US Department of Transportation's National Highway Traffic Safety Administration (NHTSA)-proposed standard on electronic stability control systems for heavy vehicles.

The system was first introduced by Meritor WABCO in 2005 and combines Roll Stability Control (RSC) and yaw or rotational control. ESC can reduce the risk of vehicle instability while on slippery surfaces or taking evasive action, limiting the likelihood of jack-knife and drift-out conditions. If a potential rollover risk is detected, tractor-trailer speed is reduced through engine control and application of the engine brake, tractor, and trailer foundation brakes. Currently, Meritor WABCO has installed more than 150,000 SmarTrac stability control products on commercial vehicles in North America.
