Self-Balancing, Two-Wheel Car Invented

Lit Motors has cut their cars in half. Literally. Lit Motors has created a self-balancing, two-wheeled car that won one of Popular Science’s 2015 Invention Awards.

“With fuel efficiency crucial to easing climate change, founder Daniel Kim believes that most commuters drive around in way too much auto—especially for daily activities like commuting and grocery shopping. Motorcycles make more sense for single-passenger trips, but they are more dangerous to operate than cars, expose riders to the elements, and require skill to keep upright. Kim, a 35-year-old who wears jeans and a black t-shirt, leads the way to the company’s prototype solution: the all-electric C-1. It has two wheels, like a motorcycle, but a steel and composite outer body, like a car. He invites a visitor to sit inside the C-1 and sway from side to side. The vehicle, emitting a steady hum, stays upright. No kickstand props it up; no third wheel adds stability. ’When was the last time you balanced on a motorcycle at zero miles an hour?’ Kim rhetorically asks. ‘Never.’

A patented control system, featuring two gyros that spin in a compartment beneath the driver’s seat, is the secret to the C-1’s balancing act. The gyros provide the torque to keep the vehicle upright no matter what the driver does and to hold it at the precisely correct lean angle when the vehicle turns.

The allure of a two-wheeled, self-stabilizing car has tempted automotive designers for at least a century, but earlier prototypes had fatal flaws—the gyros were too large, the mechanical control systems too crude. The C-1 instead employs the foot-wide, high-speed, computerized technology of devices known as control-moment gyros (CMGs), which are mostly used for positioning satellites in space. Frederick Leve, an aerospace engineer with the U.S. Air Force who specializes in CMGs, says that if Lit can effectively and affordably deploy CMGs on a terrestrial vehicle, ‘that is a breakthrough. That’s dramatic.’”
