What is Speed Odometer?

[VanMelanie]

Automobile speed odometers are divided into two types: roller counters and dot-matrix LCD screens. They consist of a speedometer that indicates the vehicle's driving speed and an odometer that records the distance traveled by the vehicle. Both are housed in a common casing and driven by the same shaft. Conventional speedometers are generally magnetic induction type. Relevant information about vehicle range is as follows: 1. Introduction: Vehicle range refers to the maximum distance that can be traveled with the remaining gasoline in the tank at a fuel-efficient speed, mainly calculated automatically by the vehicle's computer based on current driving fuel consumption. 2. Influencing factors: The vehicle's range capability is affected by four factors: charging equipment, tire pressure, whether the vehicle overtakes, and whether it frequently makes sudden stops and starts.
