ABS Sensors – Stay Safe on the Road 

Brake discs and pads are essential components of the braking system, but they’re not the only elements that ensure your safety. A critical part of any vehicle's braking system is the ABS sensors (Anti-lock Braking System). 

The ABS system prevents the wheels from locking during braking. How does it work? When braking, wheels may temporarily lock. ABS reduces brake system pressure when wheels begin to skid, restoring traction and preventing prolonged lock-up. This system is part of the Advanced Vehicle Control Systems group and helps avoid: 

• vehicle drifting, 
• spinning, 
• loss of vehicle control.

Thanks to this system, your car maintains steerability during emergency braking. 

The ABS sensor collects data on the rotational speed of the wheels, which is why it’s also called the wheel speed sensor. This information is sent to the ABS system for processing. The braking force is then controlled by the system, preventing wheel lock during sudden braking. Locked wheels reduce your ability to avoid obstacles on the road. 

A properly functioning system and ABS sensors provide specific feedback during hard braking. First, the ABS warning light on the dashboard lights up, and you may feel the brake pedal pulsing under your foot. This indicates that your car's wheel speed sensor is operating correctly. 

ABS sensors are exposed to various external factors such as moisture, water, and sand. These elements can cause wear and tear over time, potentially leading to failure of the wheel speed sensor. The ABS warning light on the dashboard will notify you of this issue. Such a malfunction can endanger all road users. During sudden braking, you may lose control of the car, leading to accidents. Therefore, replacing a faulty ABS sensor is an urgent necessity. 

Passive and Active ABS Sensors – Types of Wheel Speed Sensors 

All ABS sensors are located either in the wheel hubs or, in older models, near the car wheels. They are categorized by their operating mechanism. Your vehicle may have either a passive or active ABS sensor. What’s the difference? 

Passive sensors are connected to a toothed wheel or ring on the hub. As the sensor passes the teeth, it generates a magnetic field. The passive sensor sends this data to the ABS system, which processes it to determine the appropriate braking force. 

Active ABS sensors work based on a magnetic ring, featuring north and south pole regions. Inside the sensor are semiconductor elements that detect changes in the magnetic field and generate data on wheel rotation speed. This information is transmitted to the ABS system to monitor wheel activity during driving. 

Many drivers prefer active ABS sensors because they activate at speeds as low as 3 km/h. Active sensors offer an edge over passive ones by functioning even at near-zero speeds. However, both types of fully functional wheel speed sensors significantly enhance safety for you and other road users.

FAQ

What is ABS, and what is its role in a vehicle's braking system?

ABS prevents wheels from locking during braking by reducing brake system pressure. This helps maintain traction and prevents loss of vehicle control.

How do ABS sensors work, and why are they crucial for driving safety?

ABS sensors collect wheel rotation speed data and send it to the ABS system, which controls braking force. This prevents wheel lock, enhancing steerability and reducing road hazards.

Why choose ABS sensors from Inter Cars, and what are the key benefits of shopping with them?
