New steering system proposed to increase electric-car efficiency
] Text [ +
The Karlsruhe Institute of Technology (KIT) in Germany and automotive supplier Schaeffler are working to develop a new type of steering system specifically for electric cars that could improve their efficiency.
As with most internal-combustion cars, electric cars use a power assist to decrease steering effort. This draws electricity from a car’s battery pack, affecting range, the two partners note. KIT and Schaeffler propose a system that does away with the standard apparatus of a steering column linked to the wheels by tie rods. Instead, the prototype system uses individual electric motors for each of the front wheels to steer.
