Event Data Recorder systems (green box / black box), are designed to monitor driving pattern recognition problems (steering, deceleration, acceleration).These systems, functioning in part to prevent / reduce the distraction caused by the prolonged driving in a state of disorientation with road driving tasks (fatigue, drunkenness, etc.). System composed of sensors that collect data from various vehicles (fuel consumption, speedometer, steering system, etc.), information integration into creating real-time driving profile. When the system detects a dangerous driving pattern, turned on a warning (visual / vocal), given immediately to the driver and / or transferred directly to the control center to allow the fleet manager to contact the driver extreme case even disable the car engine remotely (disabling the fuel pump). There are several technologies to diverse applications that grow each year
