The most common wheel speed sensor system consists of a ferromagnetic toothed reluctor ring (tone wheel) and a sensor (which can be passive or active). The tone wheel is typically made of steel and may be an open-air design, or sealed (as in the case of unitized bearing assemblies). The number of teeth is chosen as a trade-off between low-speed ...
There are four main components of ABS: wheel speed sensors, valves, a pump, and a controller. ABS speed sensors Speed sensors (Encoders) A speed sensor is used to determine the acceleration or deceleration of the wheel. These sensors use a magnet and a Hall effect sensor, or a toothed wheel and an electromagnetic coil to generate a signal. The ...
A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The data from the yaw sensor is compared with the data from the steering wheel angle sensor to determine regulating action. [47] A lateral acceleration sensor that measures the vehicle's lateral acceleration. This is often called an accelerometer. Wheel speed sensors that measure wheel speed. Other sensors can include:
Throttle position sensor. Tire pressure sensor. Torque sensor. Transmission fluid temperature sensor. Turbine speed sensor. Variable reluctance sensor. Vehicle speed sensor. Water-in-fuel sensor. Wheel speed sensor.
A Hall effect sensor (also known as a Hall sensor or Hall probe) is any sensor incorporating one or more Hall elements, each of which produces a voltage proportional to one axial component of the magnetic field vector B using the Hall effect (named for physicist Edwin Hall). Hall sensors are used for proximity sensing, positioning, speed ...
