The new ECAS technology electronic control unit (ECU) will be fitted on the vehicle's frame that results in more efficient installation and reduces costs in original equipment manufacturing processes to manufacturers. Until now, the ECAS ECU - that was first introduced in 1986 - was placed in the vehicle's cabin.

WABCO claims that the new ECAS system will significantly reduce vehicle weight due to its lighter components that results increase in fuel economy. It provides fuel saving by lowering the vehicle chassis and lifting axles which helps reduce the vehicle’s aerodynamic and rolling resistance.

The ECAS technology will also help in reducing noise emission through improved design of air compression valves due to a more effective acoustic filter, which makes commercial vehicles more environmentally friendly.

The new system maintains the vehicle parallel to the road surface at a pre-set level. It increases vehicle safety for optimal load protection and stable vehicle operation.

WABCO ECAS has been incorporated with electronic shock absorber control that enables traction optimization and provides controller area network databus compatibility for faster, better onboard electronic communication among vehicle sensors and controls. It also ensures a constant vehicle height selected by the driver for safer loading and unloading, among other functions.

Jean-Christophe Figueroa, vice president of vehicle dynamics and control at WABCO, said: “Our new ECAS technology marks 25 years of WABCO leadership in electronically controlled air suspension systems. It provides optimal vehicle safety and driver effectiveness while lowering manufacturing costs, boosting fuel efficiency and reducing environmental impact.

“Our passion is to continue to deliver innovative air suspension solutions to meet the rising standards of vehicle makers and transport operators around the world.”

WABCO is a supplier of safety and control systems for commercial vehicles. It is headquartered in Brussels, Belgium. The company reported sales of $2.2 billion in 2010.

In May 2011, WABCO signed a long term agreement with Hyundai Motor to develop and supply an emergency braking technology - OnGuardPLUS system.

Will the new technology enhance sales of WABCO?
