Wheelies: Computers help electric cars turn

Researchers find electronic solution for the different wheel speeds needed to make these “green” cars safely round a corner

Designing an electric car isn’t as simple as it might seem. Engineers can’t just swap out the gas tank for a big bank of batteries. Besides using a different energy source, many electric cars also transfer energy to the car’s wheels in a different way. Instead of gears, they relay the power with electrical cables. This simplifies a car’s mechanical layout. It also, however, makes it much harder to control an electric car’s wheels during a turn. Luckily, engineers at Ohio State University thin...
