ABS SENSOR FOR 2019 FORD FOCUS is part of the vehicle’s electronic braking system. This intelligent braking system prevents wheel lock-up during emergency or sudden braking. This prevents skidding and loss of control in the presence of obstacles. The ABS sensor, often called the ABS Wheel Speed Sensor, detects the speed of each wheel and transmits signals to the Electronic Control Unit (ECU) to control wheel slip. This is an intelligent braking system that prevents wheel lock-up during emergency or sudden braking, preventing skidding and loss of control. The ABS system is currently the most intelligent and safest system equipped on new generation vehicles. The ABS wheel speed sensor typically consists of a magnet encased in a coil and a toothed signal ring. The passage of the signal ring past the magnet creates a change in the magnetic field passing through the coil inside the sensor. This generates a signal through electromagnetic induction. This signal is then converted into a digital signal and sent to the Anti-lock Braking System (ABS) control unit. After receiving the digital signal, the control unit calculates the appropriate friction coefficient and applies braking force to each wheel according to the calculated coefficient. The optimal friction coefficient usually ranges from 10-30%, but it depends on various conditions such as road conditions, tire construction and pressure, and current load. The control unit can make minor adjustments to this coefficient.
Older ABS sensor configurations had sensors located outside the wheel axle on other components such as the steering knuckle or differential housing. This measured the speed of the two drive wheels based on the rotation speed of the crown gear. However, ABS wheel speed sensors in current ABS systems are integrated into the wheel assembly itself. The ABS wheel speed sensor measures the rotational speed of a signal ring. This signal ring is mounted on the output of the half-shaft or wheel hub assembly. A vehicle may have one or four ABS wheel speed sensors at the wheels, depending on the vehicle’s system layout.
The automotive ABS sensor system consists of: Speed sensor, hydraulic valve, hydraulic pump, and control system.
- The speed sensor helps the vehicle detect if any wheels are locking up during braking. This sensor is located on each wheel or in the differential.
- The hydraulic valve controls the brake pads on each wheel. It includes three valves (open, close, and release valves).
- The hydraulic pump is responsible for pumping and releasing to change the pressure on the vehicle’s wheels through the hydraulic valve system.
- The ABS control system receives signals from the speed sensor to calculate and make appropriate adjustments to the braking pressure on each wheel to ensure maximum safety.
Modern vehicles typically have ABS sensor systems on 2, 3, or 4 wheels on completely independent channels. When the vehicle starts, the ABS system is activated only when the vehicle speed exceeds 10 km/h. At this time, the ABS warning light will illuminate and then turn off within a few seconds. If the ABS warning light does not turn off at this speed, it indicates a problem with the system and requires inspection. ABS speed sensors have a relatively long lifespan, supporting up to 50,000 km of vehicle operation. Maintenance is recommended every 30,000-40,000 km to ensure optimal operation and driver safety. The ABS system is located in 2, 3, or 4 different locations with a complex structure. Therefore, when there is a problem with the ABS system, tests are needed to accurately determine if the issue is with the rotor or sensor. Sometimes, simple cleaning is enough to restore normal operation; however, in many cases, diagnostic equipment is required to pinpoint the cause.
