InnovationsMercedes-Benz adds lane changes to its autonomous driving offeringsResize Text Print Article Comments 0By Matt McFarland December 9 Highway drivers will only need to activate their turn signal to change lanes in the E-Class. (Daimler)The auto industry took a small step toward autonomous driving when Mercedes-Benz announced Wednesday that it will automate some lane changes on its new E-Class next spring.Drivers at highway speeds will only need to activate a turn signal, and the car will then switch lanes, provided it determines it’s safe to do so. The new feature from Daimler — which some have called the leader in autonomous driving — is similar to a feature in Tesla’s autopilot that arrived in October.For the automated lane change to work, the car must be traveling between 50 mph and 112 mph and having steering assist activated. (That feature keeps the vehicle in the center of the lane.) Once the turn signal has been on for two seconds — and the car’s sensors determine a safe change can be made in three seconds — the vehicle will change lanes. The E-Class will rely on a camera and radar to ensure there isn’t a car in its path and to identify lane markings. Mercedes-Benz says the system will only work on multi-lane highways.
