Description
Necessary for vehicle development, data acquisition systems are utilized for viewing dynamic effects on the entire vehicle. These systems will monitor acceleration, cornering, braking, surface, and driver effects. Virtually every manufactured vehicle utilizes many different sensors to maintain engine operation commonly known as engine management. The Formula SAE vehicle maintains separate engine management and data acquisition systems, utilizing separate software for logging data. Interfacing the engine management and data acquisition system is of immense value, harnessing the ability to gather data from every portion of the vehicle with one system. The Interface functions on simple principles, the data management system outputs data through a transmit line, sending all engine specific sensor output values. The data acquisition system interprets the information through a receive line. The interface option purchased did not function as described. It was programmed for higher functioning engine management systems, different from the current system. The data acquisition system received data at a different rate than what the engine management sends. The electrical engineering students built an AVR microprocessor to convert the data rates that the engine management system was sending so the data acquisition unit could read and interpret the data. The team successfully accomplished the communication link between the two systems and worked on mapping out the correct channel identification codes and values. The team can now utilize all information through a single-wire, using one system allowing for superior testing, and diagnostic capabilities.
