Minn. professor works on hybrid hydraulic project

MINNEAPOLIS - University of Minnesota researchers are working on an alternative to the electric hybrid vehicle. Hybrid hydraulic vehicles have recently been built as the new model for large vehicles that start and stop frequently, such as delivery trucks. But mechanical engineering professor Kim Stelson says he hopes to develop hydraulic technology for small passenger cars. . . . Recently I was discussing with a UK HCH team about rally work. One problem is the IMA has limited power since it looks to be designed to optimize engine performance. However, a parallel, hydraulic system opens up how much energy can be absorbed and fed back for speed and rear-wheel traction. IMHO, this opens up the performance window significantly although I don't want to trivialize the control law challenges. Bob Wilson |
