Thevehicle speed sensor, also known as a transmission speed sensor or output shaft speed sensor, plays an active role in your car's transmission and cruise control systems. There are also ABS wheel speed sensors (WSS) on a vehicle's wheel hubs (both on the front axle and rear axle). Chapter1: Animation and Commercial Vehicle Wheel Speed Sensor Market Product Definition, Product Types, Volume, and Revenue Analysis of Each Type in North America, Europe, Asia-Pacific, Latin Thesensor is mounted at a specific gap from a toothed reluctor ring. As the teeth pass by the wheel speed sensor, it changes the magnetic field and produces alternating current or AC voltage. The AC voltage can be seen by a scope as a sine wave. The voltage signal will increase in amplitude with an increase in the speed of the reluctor ring. TheHall-type wheel speed sensor is made using the principle of Hall effect. The Hall-type wheel speed sensor has also been widely used in automobiles, and has the following characteristics: the output signal voltage amplitude value is not affected by the rotation speed; the frequency response is high; Strong anti-electromagnetic wave interference ability. Thepassive speed sensor creates its own AC signal that changes frequency with wheel speed. This signal is only present while the wheel is turning at a rate fast enough to create the AC signal. Vehicles equipped with passive wheel speed sensors do not read at or below 2 mph coming from a dead stop. During a wheel-spin condition, or under a Thetwo most important things to know about wheel speed sensors are: 1. What kind of sensor to use 2. Where they can be located. The most common place to find a factory vehicle speed sensor is on the gearbox where you'd usually find a sensor detecting the speed of the output shaft which is directly related to road speed. j7At0.
