tripcomputer

A trip computer is an onboard computer found in motor vehicles that gathers and displays trip-related data to help drivers monitor efficiency and planning. It typically collects information from the vehicle’s sensors and control modules and presents metrics such as distance traveled, elapsed time, average speed, instantaneous speed, fuel consumption, and estimated range.

Core functions commonly include trip distance, trip time, average speed, instantaneous speed, average fuel economy (for example liters per 100 kilometers or miles per gallon), and instantaneous fuel consumption. Many systems also provide an estimated range or distance to empty based on current fuel level and recent consumption, and they may track fuel economy over a trip or display eco-driving indicators and maintenance reminders.

Data sources and calculation methods vary by system. Modern trip computers usually obtain data via the vehicle’s CAN bus from sensors such as fuel flow or level, mass air flow, oxygen sensors, wheel speeds, and injector information. The range estimate combines current fuel quantity with recent consumption trends. Earlier or simpler implementations relied on mechanical odometers or manual input.

Interface and usage are designed for easy access, typically integrated into the instrument cluster or infotainment display and accessible through steering-wheel controls or central touchscreens. In electric and hybrid vehicles, the trip computer often adds energy consumption metrics and remaining electric range, alongside conventional fuel data.

Overall, the trip computer serves as a lightweight, centralized source of trip metrics to aid driving efficiency and trip planning.
