LOUISVILLE, KY. Brussels, Belgium-based Wabco Holdings Inc. is showcasing its “breakthrough” hydraulic anti-lock braking system (ABS) with its integrated ESCsmart electronic stability control (ESC) here at the Mid-America Trucking Show.
According to Wabco, the system “marks the first time within the commercial vehicle industry that these two vehicle safety technologies – ABS and ESC – have been integrated for hydraulic brake applications on medium-duty trucks and buses.
The company explained thatABS with integrated ESC for hydraulic applications improves the vehicle’s directional stability and helps protect against roll-over, skidding and spin-out during critical driving situations. In North America, Wabco noted, initial government mandates for ESC are anticipated to come into force starting in 2016.
Wabco said this latest addition means it can now“uniquely”deliver hydraulic as well as pneumatic ABS with ESC systems for manufacturers of commercial vehicles of all sizes from Class 5 to Class 8.
“Wabcois the first supplier to bring the technological advancement of hydraulic anti-lock braking systems integrated with electronic stability control to the commercial vehicle market,” said Nikhil Varty, Wabco president, Americas, at a news conference. “Having successfully adapted these systems to meet the specific requirements of the North American marketahead of the anticipated ESC legislation coming into effect in 2016, Wabcocan now offer original equipment manufacturers the broadest range of options in safety technology.”
Varty said that from 2014, Wabcowill roll out its hydraulic ABS in combination with ESCsmart. He pointed out that ESCsmart uses “computational simulation”to achieve ESC technical validation on trucks and buses. Therefore, it’s designed to be programmed on the assembly line, enabling new vehicles to be driven away immediately. Varty noted also that the hydraulic ABS with ESC system uses30%less mounting space and weighs 20%less than Wabco’scurrent hydraulic braking systems.
“By eliminating calibrating driving procedures and physical testing of all variants of vehicles, ESCsmart significantly reduces the time and labor currently required by the traditional approach to ESC technical release,” Varty advised. “This means vehicle makers will be able to respond more quickly and flexibly to customer needs by introducing new vehicle types within shorter development times.”
He added that ESCsmart’s enhanced functionality also offers a continuous “self-learning” capability for fleet operators, since the system continuously monitors vehicle characteristics and automatically self-adjusts for optimal performance.
Wabco also announced that it is now supplying its “c-comp”compressor with integrated clutch to two European-basedglobal manufacturers of commercial vehicles.The company said the c-comp boasts the industry’s most compact compressor design and that it ”combineshighperformance and best-in-class-efficiency.”
The company said it plans to introduce thec-comp compressor to the North American market during 2013.
According to Wabco, its c-comp air compressor technology “optimally disengages the compressor through a pneumatic signal when no air is needed, allowing fuel savings up to 145 gals. annually in long-haul operations of 125,000 miles in typical North American driving conditions.”
The c-comp features a simple on-off control and only draws power from the engine during the pumping phase, switching off completely during the long off-load phase. Wabco said this leads to a significant reduction of the compressor’s overall energy demand. In addition, according to the manufacturer, thisalso reduces maintenance costs due to lower carbonization and at the same time, enhances driver comfort due to reduced noise levels.
The company also announced that production trucks built by Daimler Trucks North America (DTNA)are now on the road fitted with Wabco’s MAXXUS heavy-duty single-piston air disc brake technology.
Wabco entered into a long-term supply agreement with DTNA in June 2012; as a result, MAXXUS brakes began being fitted to DTNA trucks last month. MAXXUS air disc brakes are currently available onCascadia, Coronado, Columbia, Business Class®M2 and SD models as well as on 4700, 4800, and 4900 models.
“DTNA is one of the leading manufacturers of commercial vehicles in North America and we are proud to supply them with Wabco’s MAXXUS air disc brakes, a game-changing generation of high-performance, low-weight braking technology that significantly increases vehicle safety and efficiency,” said Varty.
“MAXXUS, being specifically tailored for the local market, is yet another example of Wabco’s differentiation through technology leadership, and a further demonstration of the company’s commitment to serve North American customers,” he added.
