Abstract: An on-board robotic system used to control the acceleration, cruising, coasting, braking and idling of electric vehicles. It comprises a microprocessor having a non-volatile memory, a fifth wheel, a stall detection module, an anti-roll module, a brake release and a switch along with a plurality of custom sensors and transducers for actuating various controls of the electric vehicle. The DRIVE which is an acronym for Dynamic Robotic Interface for Vehicle Evaluation mounts in an electric vehicle and regulates the vehicle's speed on a track while a human controls the steering. The system also can test vehicles on a chassis dynamometer without any modification. The main purpose of the DRIVE is to determine driving range of the electric vehicle.
