Understanding your vehicles’ “health” enables you to make crucial performance decisions, such as when to perform preventive maintenance, what actions to postpone until the next maintenance cycle, and whether a driver is causing any vehicle damage through poor driving habits. The answers to these questions can keep a fleet’s health in check and help maximize business uptime. The required actions can improve efficiency and prevent damage due to severe wear and tear.
Modern vehicles contain many microcontrollers that connect into a Controller Area Network (CANBUS), the biggest being the Engine Control Unit (ECU). CANBUS is a message-based protocol, used in the On-Board Diagnostics OBD-II vehicle diagnostics standard. After turning the vehicle switch and subsequently throughout a vehicle’s trip, the microcontrollers send status messages that are read, filtered, and analyzed. In the event an exception to certain thresholds or a sequence of contingencies is detected, a report or an alert is sent for intervention.
