Introduction
In the rapidly evolving automotive industry, technology continues to redefine vehicle control. Autonomous driving requires comprehensive vehicle control, and the braking system is a critical element. Brake-by-wire technology enables precise computer control of vehicle braking, supporting the implementation of autonomous driving functions.
Overview of Brake-by-Wire Technology
Brake-by-wire replaces conventional mechanical linkages with electronic sensors and actuators to control braking. This approach can improve braking performance and safety while enabling integration with automated driving systems. Sensors play a central role: for example, when the driver depresses the brake pedal, position sensors and switch chips detect the input and initiate control actions to safely stop the vehicle.
