Geely Binyue's permanent magnet and Hall-style black wheel speed sensor are used to measure vehicle speed
Description:
Geely Binyue's wheel speed sensor is an important part of the vehicle used to detect the wheel speed.
The wheel speed sensor is usually installed in the position of the front wheel brake disc on the hub of each wheel. Its main function is to transmit the speed signal of the wheel to the relevant systems of the vehicle, such as anti-lock braking system (ABS), electronic stability program (ESP), vehicle dynamic control system (VDC), etc., to realize the vehicle system. Accurate control of dynamic and stable control and other functions.
The wheel speed sensor types that Geely Binyue may use include magnetoelectric or Hall type.
The advantage of magnetoelectric wheel speed sensor is that the manufacturing cost is relatively simple, the structure is relatively simple, and it is not afraid of sludge. It is mainly composed of permanent magnet, polar axis and induction coil. The working principle is: the magnetic force line mainly comes out through one pole of the magnetic core, passes through the tooth ring and air, and then returns to the other pole. Whenever the wheel is running, the magnetic resistance will be changed by inducing the magnetic field in turn, resulting in corresponding changes in the electric potential. Each frequency and amplitude reflect the speed of the wheel rotation. However, the disadvantage of the magnetoelectric wheel speed sensor is that the frequency response is not very high. When the vehicle speed is driving at high speed, the response frequency may not keep up, resulting in error signals, and the anti-electromagnetic interference ability is poor, and the output signal amplitude is relatively small.
The Hall wheel speed sensor is composed of two parts: a sensor head and a gear ring. The sensor head contains a permanent magnet, a Hall element and an electronic circuit. This kind of sensor is manufactured using the principle of the Hall effect. Its advantage is that the output signal voltage amplitude is not affected by the speed, the frequency response is high, and the anti-electromagnetic interference ability is strong. When working, the current is controlled by both ends of the semiconductor. If the magnetic field is added in the vertical direction of the chip, the chip will generate a potential to control the current and magnetic induction intensity at both ends. The output of the signal mainly depends on the magnetic induction intensity. The Hall potential pulse is generated by the change of input intensity. After internal amplification, shaping and amplification, the speed of wheel rotation is reflected through the pulse frequency.
The vehicle's speed sensor has an important impact on driving safety and performance. They can feedback the speed information of the wheels in a timely and accurate manner to help the vehicle's control system function better, such as preventing the wheel from being locked during emergency braking and maintaining the stability and handling of the vehicle.
