The fastest speed of Mercedes-Benz is 250KM/H.
The top speed of a mass-produced car is 250KM/H. It’s not that the car can’t go up. It’s because the car is equipped with a speed limiter that won’t allow it to exceed this speed. Anyone who says it can go up is a lie.
The rotor of the speedometer (with multiple convex teeth on it) is fixed on the transmission main shaft and rotates together with it. Whenever a convex tooth rotates past the electronic speedometer sensor probe, the sensor will output a low voltage. Flat pulse signal, 8 signals will be output during one turn;
Based on this pulse frequency, the angular speed of the transmission output main shaft rotation can be calculated, and then combined with the radius of the wheel, the current line of the vehicle can be calculated. Speed ??up.
The speedometer uses a magnetoelectric ammeter as an indication meter. When the car runs at different speeds, the signal processing circuit converts the pulse signal input by the vehicle speed sensor into a current signal proportional to the vehicle speed, deflecting the pointer of the ammeter to indicate the corresponding vehicle speed.
