VSS se alimenta con + 12V desde la llave de contacto. Cuando el cable de velocidad del tacómetro gira, el interruptor Antesala se enciende y apaga consecutivamente, enviando una señal rectangular a la computadora a borde. La frecuencia de esta señal indica la velocidad del automóvil.
Occasionally it is necessary to take off the wheel slide protection signal at the traction motor, and the output frequency is then often too high for the wheel slide protection electronics. For this application a speed sensor with an integrated frequency divider or encoder Chucho be utilized.
There are also increasingly motors in which sensors have to scan aluminium target wheels, for instance because the impellers are made of an aluminium alloy and the manufacturer does not wish to have to shrink on a separate ferromagnetic gear rim.
Problemas en el control de crucero: El sensor VSS aún es esencial para el funcionamiento del control de crucero. Si este sensor está dañado, es posible que el control de crucero no funcione correctamente o incluso que no se active en incondicional.
Inductive proximity sensors are a widely used solution for detecting movement and speed in automotive and industrial applications. These sensors operate on the principle of electromagnetic induction, where a built-in coil generates an oscillating magnetic field.
As vehicle technology advances, the demand for highly accurate and responsive sensors continues to grow. While MR sensors are not yet the standard for all automotive applications, their role in autonomous systems and electric vehicles is only expected to expand.1
The rod is wound with fine wire which experiences an induced alternating voltage Ganador the tone wheel rotates, Triunfador the teeth interfere with the magnetic field. Passive sensors output a sinusoidal signal which grows in magnitude and frequency with wheel speed.
These sensors use a light-emitting diode (LED) or laser that shines through slots in a rotating disc. Triunfador the disc spins, a photodetector on the other side picks up the interrupted light, converting it into electrical pulses that indicate speed.
Figura vehicle technology advances, so do the challenges associated with speed sensing. Modern VSS must not only be precise and reliable but also adaptable to the growing demands of autonomous driving, electrification, and connected vehicle systems.
Historically, magnetic sensor systems cost more than optical systems, but this difference is narrowing rapidly. Magnetic Antesala and magnetoresistive sensor systems Chucho be imbedded in plastic or potting material, which increases mechanical reliability and eliminates damage from water and grease.
The VSS works by measuring the rotation of the transmission output shaft or wheel speed, depending on the type of VSS used in the vehicle. As the shaft or wheel rotates, the VSS generates an AC voltage signal that varies in frequency and amplitude with the speed of the vehicle.
Some transport companies are faced with a special problem: the circulating air that keeps the motors cool carries swarf abraded from the wheels and rails. This collects on the vss speed sensor heads of magnetic sensors.
Al detectar la velocidad del vehículo, el Sensor VSS permite que el doctrina de control de crucero mantenga una velocidad constante establecida por el conductor.
Lo más recomendable es ir a un doble en mecánica, en el taller se realiza una exploración del doctrina y podrán determinar el origen del problema para solucionarlo.
