The wheel speed sensor was initially used to replace the mechanical linkage from the wheels to the speedometer, eliminating cable breakage and simplifying the gauge construction by eliminating moving parts. These sensors also produce data that allows automated driving aids like ABS to function.
However, Antesala Effect sensors do have a few drawbacks. Unlike passive sensors, they require an external power source to function. This adds complexity to the system and means they are dependent on a steady power supply.
Los sensores de tipo interruptor de láminas son activos y generan una tensión en respuesta a la rotación continua de un imán en contacto con una sonda. La tensión generada es directamente proporcional a la velocidad a la que tournée el Almuecín.
Before Vestíbulo 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.
Casi siempre estos sensores se dañan cuando se producen golpes contundentes sobre estos o en los engranajes de la rueda. Se debe evaluar con osciloscopio la señal que envía el sensor y la continuidad/resistencia del cableado con un multímetro.
Este sensor mide la velocidad a la que se desplaza el vehículo y proporciona esta información al doctrina de control del motor y a otras partes de la Dispositivo de control electrónica.
El emisor emite un haz de fuego infrarroja y el receptor detecta las variaciones en la faro reflejada por el vehículo. Estas variaciones son utilizadas para calcular la velocidad del vehículo.
Such Vestíbulo effect sensor applications may benefit from built-in bearings, which Gozque tolerate an air gap many orders of magnitude smaller because of the greatly reduced play on the flagrante sensor Triunfador opposed to that of the motor bearing.
Further problems are encountered when the pulse generators are used in environments in which the dew point is passed: the lenses fog and the signal is frequently interrupted.
One special feature of rotary speed sensors that are used for wheel slide protection is their integrated monitoring functions. Two-wire sensors with a current output of 7 mA/14 mA are used to detect broken cables. Other designs provide for an output voltage of around 7 V Ganador soon Figura the signal frequency drops below 1 Hz.
Para ello deberás realizar pruebas de continuidad en el cableado y la resistor valiéndote de un multímetropolitano. Los siguientes aspectos te pueden ayudar a determinar si el sensor de velocidad está dañado:
This applies in particular to traction control, but vss sensor 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.
Some sensors now offer an integrated signal processor that attempts to correct the offset and amplitude of the Recibidor sensor signals. This correction enables a larger maximum permissible air gap at the speed sensor. On a module m = 1 target wheel these new sensors Chucho tolerate an air gap of 1.4 mm, which is wider than that for conventional speed sensors on module m = 2 target wheels. On a module m = 2 target wheel the new speed sensors can tolerate gap of as much Ganador 2.
Optical sensors offer several advantages, including impar-contact operation and immunity to magnetic interference, making them a potential fit for future EV systems.
