Powertrain Systems

The Delphi Transmission Electro-Hydraulic Control Module is a complete control system for hydraulic fluid flow. The module provides "the brains" for fluid distribution in a vehicle transmission. It is fully assembled and tested, and it contains all the necessary elements including:

• Electronics
• Sensors
• Actuators
• Electrical and hydraulic connections

Benefits

• Integrated electronics and hydraulic controls provide reduced actuator manufacturing variation since the electronics are calibrated to the hydraulics. They also provide a "smart" system that "learns" and makes adjustments and enables stand-alone transmission systems.
• Direct sensing of pressure and temperature enables closed-loop control and optimization through calibration.
• Fully assembled and tested modular design provides improved quality and reliability, while offering vehicle manufacturers lower cost, and the potential for less assembly time and smaller floor space requirements.
• Reduced size and mass provides design and packaging flexibility and can contribute to vehicle fuel efficiency.
• Flexible modular design offers customization opportunities for specific transmission applications.
• The module's design enables it to be remanufactured, unlike competitive products.

Typical Applications

The Delphi Transmission Electro-Hydraulic Control Module can be used in a wide range of automatic transmissions and other applications requiring fluid management to hydraulic cylinders. The design can be easily modified for packaging to meet individual customer requirements.

Performance Advantages

The Delphi Transmission Electro-Hydraulic Control Module offers smoother shift feel and less variation in transmissions. With electronic and hydraulic controls calibrated together, the module minimizes system variation.

The Delphi Advantage

Delphi has one of the industry's most complete portfolios of sensors and actuators, and a thorough understanding of the entire powertrain management system. Delphi offers global manufacturing capabilities for sensors and an in-depth knowledge of regional market requirements. Delphi has the experience and the expertise to provide a single device or a multifunctional "smart" module to meet specific customer requirements.
