A speedometer is a device used to measure and display the live speed of vehicles. Speedometer is usually located on the dashboard of any vehicle such as motor bike, car, train, bus and aero plane. The speedometer provides real-time information about the speed of the vehicle, usually in miles per hour (mph) or kilometers per hour (km/h).
Who Invented SpeedoMeter?
The speedometer was invented by Croatian inventor and physics professor Josip Belusic in the year 1888 and was previously called "velocimeter". His invention allowed drivers to monitor their vehicle's speed, providing an important tool for maintaining safe and legal speeds on the road.
Types of SpeedoMeter
Mechanical speedometer is a conventional device used in vehicles to display vehicle speed. It operates through a mechanical connection to the vehicle's transmission system.
The analog speedometer is also a traditional instrument found in vehicles, consisting of a circular dial with a moving needle that indicates the current speed. It operates mechanically by connecting to the vehicle's transmission system.
Digital speedometer is a modern device that displays the vehicle speed in numerical format on a digital screen. It uses electronic sensors to measure speed, often integrated into digital dashboard displays, with additional features such as fuel efficiency.
GPS-based speedometers rely on Global Positioning System technology to determine vehicle speed with high accuracy.
A heads-up display (HUD) displays the speedometer and other information on the vehicle's windshield, allowing the driver to see important details without being distracted from the road. It enhances safety by providing real-time information in the driver's line of sight.
A hybrid speedometer combines both analog and digital elements in its design. It may feature a central digital display surrounded by analog-style dials, offering a customizable interface that combines classic aesthetics with modern functionality.
