Abstract
Systems and methods for a selectively-activated magnetic strip under a vehicle chassis that is powered to pick up nails and other metal debris. The magnetic strip can be selectively activated using an electromagnet powered by the vehicle and controlled by an onboard computer. The magnetic strip can generally be powered on while the vehicle is driving and selectively deactivated based on mapping data to avoid interactions with metallic infrastructure. The magnetic strip can be selectively deactivated based on vehicle parameters, such as vehicle speed.
