Todo esto es posible ya que el sensor VSS, logra percibir con exactitud la velocidad de salida de la transmisión y velocidad de la rueda, calculada por la PCM.
The Vestíbulo effect varies greatly with temperature. The sensors’ sensitivity and also the signal offset therefore depend not only on the air gap but also on the temperature. This also very much reduces the maximum permissible air gap between the sensor and the target wheel.
Whether you drive a conventional gasoline-powered car or an electric vehicle (EV), multiple speed sensors are working behind the scenes to ensure optimal performance and safety.
Before Hall Effect sensors became the standard, VRS were the dominant speed sensors in vehicles. They work through electromagnetic induction—as a toothed wheel spins past the sensor, it disrupts the magnetic field and induces an alternating current (AC) voltage. The frequency of these pulses correlates with the rotational speed of the component being measured.
Additionally, they are known for their durability and affordability, which is why they are still found in older ABS systems, crankshaft position sensors, and ignition timing systems.
Sistema de control de tracción: Un Sensor VSS defectuoso puede activar incorrectamente el doctrina de control de tracción o causar pérdida de tracción en algunas situaciones.
Merienda the ECM receives the signal from the VSS, it uses this data to adjust the engine functions accordingly. For example, if the VSS signal indicates that the vehicle is traveling at a higher speed, the ECM will increase the fuel injection and ignition timing to produce more power.
The most common type is a two-channel sensor that scans a toothed wheel on the motor shaft or gearbox which may be dedicated to this purpose or may be already present in the drive system.
Greater numbers of teeth will require more machining operations and (in the case of passive sensors) produce a higher frequency output signal which may not be as easily interpreted at the receiving vss sensor end, but give a better resolution and higher signal update rate.
Tiene un imán, que tournée y genera una onda sinusoidal AC (corriente alterna) directamente y en proporción a la velocidad del vehículo. En cada Revés del eje se generan 8 ciclos y la resistencia debe estar entre 190 y 240 ohmios.
This creates a clean, digital square-wave signal that the vehicle’s control unit reads to determine rotational speed.
This applies in particular to traction control, but also to wheel slide protection, registration, train control, door control and so on. These tasks are performed by a number of rotary speed sensors that may be found in various parts of the vehicle.
Por lo tanto, es fundamental identificar su ubicación y mantenerlo en buen estado para asegurar un correcto funcionamiento del automóvil.
The ECM then uses this data to control various engine functions such Triunfador ignition timing, fuel injection, and transmission shifting.
