Powertrain Control Interface for Electronic Controls Used in Medium-
and Heavy-Duty Diesel On-Highway Vehicle Applications
Foreword—Electronic controls for engines, transmissions, braking systems, and retarders need to mon
measured parameters and have a method for interaction. To eliminate the need for redundant sensors and
possible conflicting data, a method municating information between electronic controls is required. By
sharing information, the vehicle installation costs can be reduced and performance enhanced with interactive
control features.
A method municating control parameters between engine, transmission, antilock braking system (ABS)/
traction control, and retarder systems is required. A long- and short-term approach has been taken to resolve the
problem. This document addresses the short-term need. The SAE Truck and Bus Control munications
Network mittee is developing a work document (draft SAE J1939) that will use
a high-speed data link, which will address the long-term need.
