Bendix Commercial Vehicle Systems LLC has reached another milestone as it strengthens its North American leadership position in the development and manufacture of leading-edge active safety and braking system technologies. In May, the Bendix ESP Electronic Stability Program full-stability system with Automatic Traction Control (ATC) became standard on the majority of Peterbilt Motors Company's Class 8 trucks and tractors, including the newly announced 579. Additionally, Bendix Wingman Advanced – A Collision Mitigation Technology, is now available as an option on Models 579, 587, 386, 384, 382, 389, 367, and 365.
Bendix was the first North American brake manufacturer to make full-stability solutions widely available for the commercial vehicle market.
"Making full stability standard represents an important, forward-thinking decision by Peterbilt, and we are thrilled that the company chose Bendix ESP as its standard technology," said Scott Burkhart, Bendix vice president and general manger, Controls group. "Peterbilt's endorsement of Bendix ESP and Bendix Wingman Advanced represents a great expression of trust and confidence in Bendix's ability to deliver the best commercial vehicle safety technology on the road today."
Since Bendix ESP was introduced in early 2005, Bendix has sold more than 175,000 units.
Peterbilt chose the Bendix ABS-based full-stability system. The system includes automatic traction control and enhances vehicle stability both by reducing engine throttle and applying vehicle braking, based on actual vehicle dynamics and driver input.
On May 23, 2012, the National Highway Traffic Safety Administration (NHTSA) published a Notice of Proposed Rulemaking (NPRM) that would require full-stability technology, known as Electronic Stability Control (ESC), on heavy trucks and motorcoaches above 26,000 lbs.
Unlike roll-only systems, more comprehensive full-stability systems – such as Bendix ESP – address both roll and directional stability. While roll-only options function on dry surfaces, full-stability systems recognize and mitigate conditions that could lead to rollover and loss-of-control situations sooner on dry surfaces, and in a wider range of driving and road conditions, including snowy, ice-covered, and slippery surfaces. Full-stability systems contain additional sensors, enabling the unit to recognize factors that could lead to truck rollovers and loss of control – often faster than a driver's capability.
Interventions are also different. Full-stability systems rely on automatic brake interventions involving the steer, drive, and trailer axles, whereas roll-only systems typically apply the brakes only on the drive and trailer axles. Slowing the vehicle quickly helps mitigate rollovers faster, while slowing and redirecting can help the driver maneuver in loss-of-control situations.
Bendix ESP is the foundation for Bendix advanced active safety technologies, such as Bendix Wingman Advanced – A Collision Mitigation Technology, which combines both adaptive cruise control and collision mitigation to help drivers mitigate or reduce the intensity of potential rear-end collision situations.
