It was tested as a bobtail, with 1 trailer and with 2 trailers.

In this case it was a 2008 Freightliner with a Detroit Diesel Series 60 Engine and A DDEC 6 controller. Test ProcedureĪs a brief overview, the following actions were performed: This article will explain the different settings and link to the data files. The RP1210 Device used to access DDEC data with a PC.Ī photograph of the instruments mounted in the cab of the truck is shown below. Monitors and records all bus traffic from the 9-pin Deutsch connector in the cab (both J1939 and J1708). Measures switch input from pressure switch Transmits data in a CAN message onto J1939 bus for correlation Measures switch input from pressure switch on brake pedal. Measures analog signals (Vehicle Speed Sensor Output, Brake Pressure) The following table lists the instruments used and their purpose. The purpose of these measurements was to determine the response of the vehicle speed sensor signals and look for noise in the signal due to the mechanical impact from coupling to a trailer. The vehicle was measured even during standard normal operations like reversing and hooking up to a trailer. The J1939 data bus was used to synchronize the data. Therefore, a significant objective of this site is to host the data collected. Robust data sets that time correlate as many measurements as possible are rare.
This paper provides much of the inspiration for this work. The paper, Timing and Synchronization of the Event Data Recorded by the Electronic Control Modules of Commercial Motor Vehicles - DDEC V, used a VBox as the reference instrumentation and showed that some of the switch events (brake and clutch) can be delayed over 1 second. BackgroundĪ paper assessing the timing and synchronization of different parameters from a DDEC 5 controlled truck was presented at the 2013 SAE World Congress.

Taking the data presented below, we can demonstrate how to synchronize the times between the report and the reference instrumentation.

When performing an accuracy assessment of the digital data stored on heavy trucks, data from reference instrumentation are compared to the reports generated by the diagnostic software for the heavy vehicle. The time synchronization is performed by oversampling the J1939 bus traffic.
A correlated measurement is one that is synchronized in time. This article explains and presents correlated measurements of a 2009 Freightliner truck-tractor with a Detroit Diesel Series 60 Engine controlled by a DDEC6 controller.
