WABCO Welcomes Pending EU Mandate on Electronic Stability Control (ESC) for Heavy Trucks and Buses

BRUSSELS, Belgium, Nov. 30, 2007 -- WABCO Holdings Inc. , today announced its support of the UN/ECE (United Nations Economic Commission for Europe) agreement that paves the way for new EU legislation mandating electronic stability control (ESC) systems for certain categories of heavy truck/trailer combinations and touring coaches. The agreement allows the EU to make ESC a mandatory requirement by reference to UN/ECE braking Regulation 13, which will require new vehicles to be fitted with ESC systems starting in 2010.

"We are proud to have brought the first ESC systems to market in 2001 and to have participated in the UN/ECE working group on braking," said WABCO chief executive officer Jacques Esculier. "We are confident that this agreement will help expedite the introduction of similar requirements in other parts of the world," he added. According to the European Commission*, Regulation 13 which is widely accepted in many parts of the world, promotes harmonization of standards and encourages the wider use of ESC systems, even in countries where they may not be a mandatory requirement.

WABCO pioneered commercial vehicle ESC in 2001 when it offered the system as an option on the company's electronic braking system (EBS). The company is one of the leading providers of electronic braking, stability, suspension and transmission control systems for the commercial vehicle industry. Today, less than 10 percent of all new heavy trucks and buses in Europe are equipped with electronic stability controls.

Stability control systems help drivers to maintain control of their vehicles in a variety of potentially dangerous situations by automatically taking corrective action, for example during sudden lane changes or while cornering at excessive speed. They can help prevent truck-trailer combinations from rolling-over, skidding or jack-knifing. Stabilization of the vehicle is achieved by selective braking on each wheel while simultaneously reducing engine power.

WABCO has a strong track record of technology leadership and pioneered many of the industry's most important innovations focused on improving the performance, safety and efficiency of commercial vehicles. These include anti-lock braking systems (ABS) developed in cooperation with Daimler in 1981, electronically controlled air suspension (ECAS) systems, automated manual transmission controls, electronic braking systems (EBS) and a range of stability control systems.

WABCO Stability Control Systems

Roll Stability Control (RSC) is integral to the anti-lock braking system (ABS). An accelerometer is mounted directly to the electronic control unit (ECU) to monitor the vehicle's lateral acceleration. The RSC system focuses on a vehicle's center of gravity, wheel speed, and the lateral acceleration threshold where rollover may occur. When critical lateral acceleration thresholds are exceeded, RSC intervenes by reducing engine torque, engaging the engine retarder and automatically applying the drive axle and trailer brakes. The deceleration resulting from the intervention reduces the vehicle speed and rollover threshold allowing improved maneuverability and stability.

Electronic Stability Control (ESC) combines the features of the company's RSC system with added yaw (horizontal-plane rotation) sensing. This improves the vehicle handling and performance if there is an impending loss of control due to rotational forces. These forces may occur as a result of rapid lane change, or cornering maneuvers on slippery surfaces.

Roll Stability Support (RSS) is an independent system for trailers and offers electronic assistance to reduce the likelihood of rollover. The technology is integrated in the trailer ABS system, requiring no additional hardware. Similar to RSC, RSS focuses on the lateral acceleration, wheel speed, and monitoring the critical lateral acceleration limit threshold. If this limit is exceeded, the trailer brakes are automatically applied helping to reduce the vehicle's speed.

While stability enhancement systems provide additional driver assistance, no system can prevent loss of control, or rollover in all driving conditions. It remains the responsibility of the driver to ensure that the physical limits of the vehicle are not exceeded.
