Which component of ABS processes all the information and signals?

The electronic control unit (ECU) is the component of the Anti-lock Braking System (ABS) that is responsible for processing all the information and signals. It acts as the brain of the ABS, receiving data from various sensors, such as wheel speed sensors and other inputs related to vehicle dynamics.

The ECU continuously monitors this data to determine the speed of each wheel and assess whether any wheel is about to lock up during braking. If a potential lock-up is detected, the ECU sends signals to the modulator valves to adjust the hydraulic pressure, preventing the wheels from locking and allowing the driver to maintain steering control.

This centralized processing ensures that the system operates effectively and efficiently, providing the necessary adjustments in real time to enhance braking performance and overall safety. Other components, while essential to the functionality of the ABS, do not interpret or analyze the data—hence their roles differ significantly from that of the ECU.
