ELYRIA, Ohio – With a major change in North American commercial vehicle braking systems coming in the form of a migration toward Electronic Braking Systems (EBS), Bendix is working closely with truck manufacturers to prepare fleets and drivers for what the technology will bring.
EBS differs from ABS (antilock braking systems) in that brake pressure is controlled electronically on every brake application – versus ABS, where that control signal is pneumatic.
“EBS has been in use in Europe for two decades, so it’s absolutely an established, road-tested safety technology,” said Richard Beyer, Bendix vice president – engineering and R&D. “Now in North America, the dual factors of advanced driver assistance systems (ADAS) and electric-powered vehicle development are driving the industry toward making EBS the base brake control system, and we know people have questions about what that means. Within three to five years, Bendix anticipates EBS will become standard in many applications, so we believe the time is right to increase awareness of this technology in the marketplace.”
Bendix Commercial Vehicle Systems LLC is the North American leader in the development and manufacture of active safety, air management, and braking solutions for commercial vehicles.
What Is EBS?
EBS is an extension of existing FMVSS 121-compliant braking technology that now allows functions in the brake system to be electronically controlled. While these controls enable EBS to deliver new brake system features, including smoother braking, and improved brake balance and feel across different load conditions, it also allows automated driver-assist features to activate braking much more frequently than current ABS systems.
More precise control during every brake application – even at the individual axle and wheel-end levels – means the benefits of EBS are realized during automated braking interventions of advanced driver assistance systems like Bendix® Wingman® Fusion™, Bendix’s flagship collision mitigation technology.
“Customers seeking smoother ADAS braking will find EBS delivers,” Beyer said. “These advanced capabilities also make EBS suited for regenerative braking on an electric vehicle by blending the pneumatic braking with retardation of electric engines. EBS also supports the ISO 11688 tractor-trailer Controller Area Network (CAN) interface for enhanced communication.”
