What is the role of the installation position of the wheel speed sensor?

The mounting position of the wheel speed sensor.

The function of the wheel speed sensor is to detect the speed of the wheel and input the speed signal into the electronic control unit of ABS. It is used to control the wheel slip rate.

At present, there are two main types of wheel speed sensors used for ABS systems: electromagnetic type and Hall type.

A wheel speed sensor is a sensor used to measure the rotational speed of a car's wheels.

The speedometer on most electric vehicles in China is converted into the speed of the car by converting the rotational speed of the car tires into the speed of the car.

Generally speaking, all speed sensors can be used as wheel speed sensors, but considering the actual factors such as the working environment and space size of the wheel, the commonly used wheel speed sensors mainly include magnetoelectric wheel speed sensors and Hall wheel speed sensors.

Composition of the sensor.

A sensor usually consists of three parts: a sensing element, a conversion element, and a measurement circuit.

1) The sensitive element refers to the part that can directly feel (or respond) to be measured, that is, the sensitive element that is measured through the sensor is converted into a non-electric or other quantity that has a definite relationship with the measurement.

2) The conversion element converts the above-mentioned non-electric power into electrical parameters.

3) The function of the measurement circuit is to convert the electrical parameters input by the conversion element into measurable quantities such as voltage, current or frequency, so as to display, record, control and process.

The role of the wheel speed sensor is to measure the speed of the wheels of the car.

Explanation: A wheel speed sensor is a sensor used to measure the rotational speed of a car's wheels. Commonly used wheel speed sensors mainly include:

Magnetoelectric wheel speed sensor, Hall wheel speed sensor. For modern automobiles, wheel speed information is indispensable, and wheel speed information is required for automotive dynamic control systems (VDC), automotive electronic stability program (ESP), anti-lock braking systems (ABS), and control systems for automatic transmissions. Therefore, the wheel speed sensor is one of the most critical sensors in modern cars.

Principle: The magnetoelectric wheel speed sensor is composed of a permanent magnetic core and a coil. The magnetic field lines come out of one pole of the core, pass through the ring gear and air, and return to the other pole of the core.

Since the coil of the sensor is wound around the magnetic core, these magnetic field lines also pass through the coil. When the wheel rotates, the gear ring synchronized with the wheel rotates, and the teeth and gaps on the gear ring pass through the magnetic field of the sensor quickly in turn, and the result is that the magnetic resistance of the magnetic circuit is changed, resulting in a change in the induced electric potential in the coil, resulting in an electric potential pulse of a certain amplitude and frequency. The frequency of the pulses, i.e. the number of pulses produced per second, reflects how fast or slow the wheel rotates.

ABS anti-lock braking system, wheel speed sensor, is mainly used to monitor the speed of each wheel, automatically adjust the pressure of the brake pump, avoid individual wheel locking, and improve the safety of the car.

Wheel speed sensor (referred to as wheel speed sensor) is provided with electromagnetic induction wheel speed sensor in the automobile anti-skid control system. It can be mounted on wheels or in a final drive or transmission.

The wheel speed sensor is mainly a sensor used to test the wheel speed of the car, and the detected rotation frequency signal will be directly transmitted to the ABS computer of the car. When the wheel speed sensor detects that the wheel has reached 40 km h, the ABS system will start to step in. Then when the car brakes, with the help of the ABS system, the pressure of the brake pump will be automatically adjusted, so as to avoid the locking of individual wheels, which improves the safety of the car to a certain extent.

The operating conditions of each part of the car are transmitted to the ECU

It provides fast and slow voltage signals for vehicle speed, and the ECU has logic analysis capabilities according to SP signals, TPS signals, and VSS signals.

Hello, the wheel speed sensor provides a signal to the ABS computer, and the computer controls the ABS pump, and the ABS pump controls the brake cylinder to make the brake not lock. Hope it helps.

Provide a signal to the ABS to control the four-wheel brakes, and a signal to the ECU to check the speed of the vehicle.

Wheel speed sensors, also known as wheel speed sensors, are usually installed in the drive axle housing or transmission housing. This is to eliminate electromagnetic and radio frequency interference caused by high-voltage live wires, on-board ** or other electronic equipment, ensure that electronic communication is not interrupted, and prevent deterioration of driving performance.

Wheel speed sensors are sensors used to measure the speed of the wheels of a car. For modern cars, wheel speed information is essential. Vehicle Dynamics Control (VDC), Vehicle Electronic Stability Program (ESP), Anti-lock Braking System (ABS), and Automatic Transmission Control System all require wheel speed information.

As a result, wheel speed sensors are one of the most critical sensors in modern cars.

Generally speaking, all speed sensors can be used as wheel speed sensors, but considering the practical factors such as the working environment of the wheel and the size of the empty, the commonly used wheel speed sensors mainly include magnetoelectric wheel speed sensors and Hall wheel speed sensors. Magnetoelectric wheel speed sensor is widely used in ABS anti-lock braking system of modern automobiles because of its simple structure, low cost, and not afraid of dirt.

Features of Hall Wheel Speed Sensors:

1.The amplitude of the output signal voltage is not affected by the speed;

2.high-frequency response;

3.Strong anti-electromagnetic interference ability.
