The Georgia Tech team has done a lot of exciting work on their EcoCAR’s control system lately. The vehicle has been drivable for several months now and the drive quality was recently improved by updating accelerator pedal mapping in accordance with AVL recommendations.

The group has held multiple conference calls with General Motors and other 2Mode teams to share ideas and help resolve issues they’ve encountered as they attempt to get the maximum capabilities out of their transmission. Currently Georgia Tech is in the progress of test-driving in EVT2, the second hybrid mode available in their transmission, and they hope to resolve the issue of keeping the engine off for electric-only operation within the next couple of weeks.

The team also expects to add more refinements to their control strategy in order to boost performance for the Spring Workshop.

Stay tuned to read about how the team fares in Ann Arbor!


The Virginia Tech EcoCAR team recently completed the first step in a multiphase flex-fuel (85 percent ethanol and 15 percent gasoline) engine integration process.

In less than a month after receiving the flex-fuel engine,  it is up and running and the controls team is communicating with the engine.

“HEVT is off to a good start, but must prepare to face even bigger challenges in the next six months leading up to competition,” said Patrick Walsh, a graduate research assistant from Richmond, VA.

What do you think of the flex-fuel engine and transmission? We think it’s pretty cool!
