    Since the speedometer measures the rotation of the gearbox output shaft, it is a relatively simple matter to use this information to work out how far the car has travelled. This is why the milometer (often called an odometer) is built into the speedometer.

    A speedometer or speed meter is a gauge that measures and displays the instantaneous speed of a vehicle. Now universally fitted to motor vehicles, they started to be available as options in the early 20th century, and as standard equipment from about 1910 onwards. [1]

    The sensors used by speedometers are usually magnetic or optical sensors. Both magnetic and optical sensors function the same way in the sense that they are capable of keeping track of “pulses” every time a gear in the transmission spins. These pulses are then sent to the ECU to calculate the vehicle speed. Speedometers have gone a long way from th...

    The technology used in our cars has gone a long way from the early days of the automobile. Back in the day, our cars used a mechanical way of telling the speed at which the vehicle is moving. The speedometers back then used wires, gears, and magnets that allowed the dial on the speedometer to tell how fast the car was moving at any given moment. To...

    Now that we have discussed that today’s speedometers use sensors that are located in the transmission, let us now look at what kind of sensors are used by this system so that we can understand how speedometers work. So, basically, different speedometers use different types of sensors but they essentially work the same way when it comes to how the s...

    All that said, how do the sensors fit into the entire system of the modern speedometer and what do these sensors do when they are capturing the speed at which the vehicle is moving? So, in that regard, let’s discuss how speedometer sensors work so that you would understand how accurate and amazing these sensors are. As mentioned, speedometer sensor...

  4. Jan 12, 2016 · The speedometer sensor is located in the transmission of your vehicle and is designed to register the driveshafts rotational speed. The sensor delivers this information through the speedometer cable and to the vehicle’s computer, which converts electrical pulses into a numerical speed.

  5. A speedometer indicates speed via a circular permanent magnet that rotates 1,000 revolutions per mile of vehicle travel. This motion is initiated by a flexible shaft driven by gears at the rear of the transmission.

  6. Apr 29, 2023 · The job of the speedometer is to indicate the speed of your car in miles per hour, kilometers per hour or both. Analog speedometers use a needle to point to a specific speed, which the driver reads as a number printed on a dial.
