A vehicle with an anti-lock brake system (ABS), an anti-skid brick control (ASR), a four-wheel drive or an electronic stability program (ESP) with a Hall acceleration sensor in addition to the wheel sensor for measurement Longitudinal and lateral acceleration of the car as it travels.
The Hall element is a Hall-based magnetic sensor that has evolved into a diverse family of magnetic sensor products and has been widely used. They can be used to detect magnetic fields and their changes, and can be used in a variety of applications related to magnetic fields. Hall devices are based on the Hall effect. Hall devices have many advantages. They are solid in structure, small in size, light in weight, long in life, easy to install, low in power consumption, high in frequency, resistant to vibration, and not afraid of pollution or corrosion such as dust, oil, water vapor and salt spray.
Movement between the Hall device and the working magnet
The Hall linear device has high precision and good linearity; the Hall switch device has no contact, no wear, clear output waveform, no jitter, no rebound, and high position repeatability. Hall devices with various compensation and protection measures have a wide operating temperature range. According to the function of the Hall device, they can be divided into: Hall linear device and Hall switching device. The former outputs an analog quantity, and the latter outputs a digital quantity.
