Delphi Features New Torque & Position Sensor on More Than $2.4 Billion of EPS System Business

Frankfurt, Germany - Delphi Steering is featuring a new non-contacting torque and position sensor on its electric power steering (EPS) systems at the 62nd International Motor Show (IAA) in Frankfurt, Germany. The highly advanced sensor technology, designed for unsurpassed durability, will be used on many of Delphi’s (PINKSHEETS: DPHIQ) EPS business awards, accounting for more than $2.4 billion (USD) in lifetime revenue globally, some of which was previously announced.

Delphi’s current portfolio of EPS systems includes column-assist, pinion-assist and rack-assist designs. The function of the torque and position sensor is the same on each. It senses torsion bar twisting (torque) and steering shaft movement (position) and sends this data to the EPS electronic controller to calculate the appropriate power assist for optimum steering.

“This sensor is critical for achieving superior performance from our various EPS systems,” said Ronald W. Voigt, director of Delphi’s Steering Business Unit. “The design target was to increase system reliability and durability to record levels, and we accomplished that goal.”

The new non-contacting torque and position sensor has a modular design with minimal parts content in a very compact package. It combines Hall-effect integrated circuitry and magnetic technology to sense and send accurate data to the system controller. Options allow sensing torque and relative position or torque and absolute position. Integration of torque and absolute position sensing functions in one electro-magnetic module is unique in the market.

Delphi’s new EPS sensor technology has no wear surfaces because of its non-contacting design and utilizes advanced electronic circuits with high reliability. It also provides superior torque sensing accuracy and absolute position accuracy without any temperature drift or fluctuation, compared to other EPS system torque sensors. The sensor accuracy, temperature performance, and package integration have no equal currently available.

“Our Column EPS systems are on 12 major vehicle programs, with our newest Pinion EPS and Rack EPS systems extending our reach into five additional programs,” Voigt said. “This new torque and position sensor provides the lifetime durability these high-performance steering systems require.”

Delphi hydraulic and electric power steering systems are recognized leaders in the industry for advanced technologies, steering feel, vehicle-tuned integration, and flexibility. With localized engineering, manufacturing, and customer sales and support, Delphi Steering currently produces steering and driveline products for a diverse base of 64 customers worldwide.

A full range of Delphi Steering technologies are on display at the IAA 2007 motor show from Sept. 13 through Sept. 22. They are showcased, along with other Delphi Corp. offerings for “driving tomorrow’s technology,” at Stand A04, in Hall 5.1 of the Exhibition Centre Frankfurt.
